100 points find the horizontal distance from the bottom of the ramp to the bottom of the platform. show your work, rounding to the nearest hundredth, if necessary.

Answers

Answer 1

The horizontal distance from the bottom of the ramp to the bottom of the platform is 57.74 feet.

What is the horizontal distance between the bottom of the ramp and the bottom of the platform?

In order to find the horizontal distance between the bottom of the ramp and the bottom of the platform, we need to use the Pythagorean theorem. Let's call this distance "d". We know that the vertical distance from the bottom of the ramp to the bottom of the platform is 50 feet, and the length of the ramp is 70 feet.

Using the Pythagorean theorem, we can solve for the horizontal distance:

[tex]d^2 = 70^2 - 50^2[/tex]

[tex]d^2[/tex] = 4,900 - 2,500

[tex]d^2[/tex]= 2,400

d = √2,400

d = 48.99 (rounded to the nearest hundredth)

Therefore, the horizontal distance from the bottom of the ramp to the bottom of the platform is 48.99 feet (rounded to the nearest hundredth).

In a recent BMO survey, many Canadian university students said they expected to owe


$26, 500 after graduation. A group of n = 64 university students are randomly selected, and


the average student loan debt is found to be $26,000 with a standard deviation of 500.


(a) Construct a 98% confidence interval for the true average student loan debt for


university students in Canada.




(b) Does this contradict the reported average of $26,500? Explain

Answers

(a) With 98% confidence, the true average student loan debt for university students in Canada falls between $25,883.5 and $26,116.5.

(b) No, this does not contradict the reported average of $26,500.

(a) To construct a 98% confidence interval, we can use the formula:

CI = [tex]\bar{x}[/tex] ± z* (σ/√n)

where [tex]\bar{x}[/tex] is the sample mean, σ is the population standard deviation (unknown), n is the sample size, and z* is the z-value from the standard normal distribution that corresponds to the desired level of confidence (98% in this case).

Substituting the given values, we get:

CI = 26,000 ± 2.33 * (500/√64)
CI = 26,000 ± 116.5
CI = (25,883.5, 26,116.5)

Therefore, we can say with 98% confidence that the true average student loan debt for university students in Canada falls between $25,883.5 and $26,116.5.

(b) No, this does not contradict the reported average of $26,500. The reported average is within the confidence interval we calculated, which means that it is a plausible value for the true average. The sample mean of $26,000 is slightly lower than the reported average, but this could be due to random sampling error.

Overall, we cannot make a definitive conclusion about the true average based on this sample alone, but we can say with 98% confidence that it falls within the range of $25,883.5 to $26,116.5.

A particular base ball field is a quarter circle with a radius of 290 feet. The baseball diamond is a square with a side length of 90 feet, and bases at its vertices. What is the area of the shaded section of the field?

Answers

The area of the shaded region of the circle is A = 57,918.5 feet²

Given data ,

First, we need to find the area of the quarter circle:

Area of quarter circle = (1/4)  π ( r )²

= (1/4)  π ( 290 )²

= 66,018.5 feet²

Next, we need to find the area of the square:

Area of square = side²

= 90²

= 8,100 feet²

Now, we can find the area of the shaded section by subtracting the area of the square from the area of the quarter circle:

Area of shaded section = Area of quarter circle - Area of square

= 66,018.5 feet² - 8,100 feet²

= 57,918.5 feet²

Hence , the area of the shaded section of the field is 57,918.5 feet²

The capacity of 1 jug is the same as the total capacity of 6 similar glasses. 10. 36 litres of
water is needed to fill 3 jugs and 19 glasses. What is the capacity of one glass?
10​

Answers

The capacity of one glass is 36/37 liters.

Let's begin by representing the capacity of one jug as "J" and the capacity of one glass as "G". From the first piece of information, we know that:

J = 6G

This means that the capacity of one jug is equal to 6 times the capacity of one glass.

Next, we are given that 36 liters of water is needed to fill 3 jugs and 19 glasses. We can use this information to form an equation in terms of J and G.

The total capacity of 3 jugs is 3J and the total capacity of 19 glasses is 19G. Therefore, we can say:

3J + 19G = 36

Now we can substitute J with 6G (from the first equation) and simplify:

3(6G) + 19G = 36

18G + 19G = 36

37G = 36

G = 36/37

Answers

The circumference of the cake board is 35π cm.

The diameter of the round cake is 30 cm, which means its radius is 15 cm. The diameter of the circular cake board is 5 cm longer than that of the cake, which means its diameter is 30 + 5 = 35 cm. Therefore, the radius of the cake board is 17.5 cm.

The circumference of a circle is given by the formula:

[tex]$$C = 2 \pi r$$[/tex]

where [tex]$r$[/tex] is the radius of the circle. Using this formula, we can find the circumference of the cake board:

[tex]$$C = 2 \pi \cdot 17.5 = 35 \pi$$[/tex]

Therefore, the circumference of the cake board is 35π cm.

In other words, if you were to wrap a string or ribbon around the edge of the cake board, it would need to be 35π cm long.

This is an important measurement to consider when decorating or transporting a cake, as it can help ensure that the cake is centered on the board and that there is enough room for any additional decorations or trimmings.

In summary, the circumference of the cake board is 35π cm.

What were the company's profits each month from March through May? Enter the answer in the box.

Answers

The company's profits for each month from March through May were $658.33.

How to find the company profits for the months of March through May?

To solve the problem, we need to use the information given and set up an equation. Let's call the profits for the months of March through May "P" (since they are the same for each month).

The company's total profits for the year can be calculated by adding up the profits for each month:

January profit + February profit + March profit + April profit + May profit = total profit

Plugging in the numbers we know:

-$4,758 + $3,642 + 3P + 3P + 3P = -$1,275

Simplifying the equation:

9P = $5,925

Dividing both sides by 9:

P = $658.33

Answers

Service fee for the over the counter deposit of R700: R10.50

Service fee for the ATM withdrawal of R500: R11.50

To determine the service fee that Tilly will incur for the given transactions,

Over the Counter Deposit of R700:

Tilly is depositing R700, the fee will be:

Fee = R3.50 + (R1.00 per R100) x (R700 / R100)

= R3.50 + R7.00

= R10.50

Therefore, the service fee for the over the counter deposit of R700 is R10.50.

ATM Withdrawal of R500:

The fee for an ATM withdrawal at own bank is calculated as R6.50 + R1.00 per R100.

Since Tilly is withdrawing R500, the fee will be:

Fee = R6.50 + (R1.00 per R100) x (R500 / R100)

= R6.50 + R5.00

= R11.50

Answers

R= 1 and the interval of convergence is (-1, 1].

To find the radius of convergence, we can use the ratio test:

lim n→∞ |(-1)^n x^(n+1) Vn+5| / |(-1)^n x^n Vn+5| = lim n→∞ |x|

This limit exists for all x, and it equals 1 when |x| = 1. Therefore, the radius of convergence is R = 1.

To determine the interval of convergence, we need to check the endpoints x = -1 and x = 1 separately.

When x = -1, the series becomes:

∑ (-1)^n (Vn+5)

This is an alternating series with decreasing terms, so it converges by the alternating series test.

When x = 1, the series becomes:

∑ (-1)^n (Vn+5)

This is again an alternating series with decreasing terms, so it also converges by the alternating series test.

Therefore, the interval of convergence is (-1, 1].

Answers

According to the above, the fishing population is divided into 53% prefer fresh water and 47% prefer salt water.

How to find the percentages of each group?

To find the percentage of people that make up each group, we must find the total number of people who were surveyed:

228 + 245 + 242 + 285 = 1,000

Once we find the total number of people who took the survey, we can find the percentage of each value by making rules of three as shown below:

Age 30 and younger and Saltwater fishing:

1,000 = 100%

228 = ?%

228 * 100 / 1,000 = 22.8%

Age 30 and younger and Freshwater fishing:

1,000 = 100%

245 = ?%

245 * 100 / 1,000 = 24.5%

Over 30 years old and Saltwater fishing:

1,000 = 100%

242 = ?%

242 * 100 / 1,000 = 24.2%

Over 30 years old and Freshwater fishing:

1,000 = 100%

285 = ?%

285 * 100 / 1,000 = 28.5%

To find the other percentages we must find the total number of fishermen by age ranges and by fishing preference:

Age ranges

228 + 245 = 473

242 + 285 = 527

1,000 = 100%

473 = ?%

473 * 100 / 1,000 = 47.3%

1,000 = 100%

527 = ?%

527 * 100 / 1,000 = 52.3%

Fishing mode preferences

228 + 242 = 470

245 + 285 = 530

1,000 = 100%

530 = ?%

530 * 100 / 1,000 = 53%

Answers

The net present value of this investment, assuming a required 8% return, is approximately $13,829.

To calculate the net present value (NPV) of this investment, we'll first find the present value of the net cash flows and the salvage value, then subtract the initial investment.

For the net cash flows, we'll use the Present Value of Annuity (PVA) formula:

PVA = Net Cash Flow * [(1 - (1 + r)^(-n)) / r]

Where:
- Net Cash Flow is $11,000
- r is the required return (0.08)
- n is the number of years (7)

PVA = 11,000 * [(1 - (1 + 0.08)^(-7)) / 0.08]
PVA = 11,000 * 4.99271
PVA ≈ $54,920

Next, we'll find the present value of the salvage value at the end of year 7:

PV_salvage = Salvage Value / (1 + r)^n
PV_salvage = 6,700 / (1 + 0.08)^7
PV_salvage ≈ $3,909

Now, we can calculate the NPV by adding the present values and subtracting the initial investment:

NPV = (PVA + PV_salvage) - Initial Investment
NPV = (54,920 + 3,909) - 45,000
NPV ≈ $13,829

The net present value of this investment, assuming a required 8% return, is approximately $13,829.

Determine whether the function is an example of exponential growth or exponential decay then find the y-intercept y=8 (2/7)^x

Answers

This function is an example of exponential decay because the base of the exponential term (2/7) is between 0 and 1. and the y-intercept is 8.

To find the y-intercept, we need to evaluate the function when x=0, which gives:

y = 8 (2/7)^0 = 8

The given function is an example of exponential decay. In an exponential function, if the base of the exponent is between 0 and 1, the function shows exponential decay, and if it is greater than 1, the function shows exponential growth.

In the given function y = 8 (2/7)^x, the base of the exponent is 2/7, which is less than 1. This means that as the value of x increases, the value of the function decreases at a decreasing rate, which is the characteristic of exponential decay.

To find the y-intercept of the function, we can substitute x=0 in the given function. When x=0, we have:

y = 8 (2/7)^0

y = 8 x 1

y = 8

This means that the y-intercept of the function is (0, 8), which is the point where the function intersects the y-axis. In this case, it represents the initial value of the function when x=0.

Therefore, This function is an example of exponential decay because the base of the exponential term (2/7) is between 0 and 1. and the y-intercept is 8.

Work out this price. ​

Answers

If Polly reduced the price and sold 3 of the remaining necklaces for £8 each, she sold the remaining necklaces for £6.70 each.

First, let's find the original cost of the necklaces:
50 necklaces * £5 = £250

Now, let's calculate the profit Polly made:
£250 * 70% = £175

So, the total amount she made from selling the necklaces is:
£250 + £175 = £425

Polly sold 40% of the necklaces for £11 each:
50 necklaces * 40% = 20 necklaces
20 necklaces * £11 = £220

She sold 3 necklaces for £8 each:
3 necklaces * £8 = £24

Now let's find the amount left after selling these necklaces:
£425 - £220 - £24 = £181

Polly has 50 - 20 - 3 = 27 necklaces remaining. Let's find the price at which she sold each of the remaining necklaces:

How much will the monthly payment be for a new car priced at $24,530 if the current finance rate is 36 months at 3. 16%? You will finance the 8% TT&L and make a 20% down payment

Answers

The monthly payment for a new car priced at $24,530 with the given terms is $630.15.


Calculating the down payment:

20% of $24,530

= 0.20 × 24,530

= $4,906.


Subtracting the down payment from the car price:

= $24,530 - $4,906

= $19,624 (amount to finance).

Adding the 8% TT&L (tax, title, and license) to the amount to finance:

  8% of $24,530

= 0.08 × 24,530

= $1,962.40.

So, the total amount to finance

= $19,624 + $1,962.40

= $21,586.40.

Converting the annual interest rate of 3.16% to a decimal:

  3.16% / 100

= 0.0316.

Calculating the monthly interest rate:

 0.0316 / 12

= 0.002633.

Calculating the total number of payments: 36 months.


Using the monthly payment formula:

P = (PV * r * (1 + r)^n) / ((1 + r)^n - 1),

where P is the monthly payment,

           PV is the present value or amount to finance,

          r is the monthly interest rate, and

          n is the total number of payments.
Now, pluggin  in the values:

P = ($21,586.40 × 0.002633 × (1 + 0.002633)³⁶) / ((1 + 0.002633)³⁶ - 1)

= $630.15.

The monthly payment for the new car will be approximately $630.15.

A parking lot is 316 feet long. Workers paint lines to make one row of parking spaces. They do not paint lines on a 28-foot length at one end of the row in order to allow cars room to turn. The workers paint lines along the rest of the row to make 9-foot-wide parking spaces. How many parking spaces does the parking lot have?​

Answers

The number of parking spaces that the parking lot has is 32 parking spaces.

How to find the number of spaces ?

To start, we must ascertain the parking lot's length designed exclusively for parking spaces. Bearing in mind that 28 feet at one end of each row is left unmarked, this distance is subtracted from the overall parking lot length:

316 feet - 28 feet  = 288 feet

It is now established that the width of each space assigned to a car is equal to nine feet. Consequently, dividing the previously determined length used for parking by the allotted width per car will determine the total number of available parking spaces:

288 feet / 9 feet = 32 parking spaces

LQ - 10.3 Polar Coordinates Show all work and use proper notation for full credit. Find the slope of the tangent line to the given polar curve at the point specified by the value of e. TT r = 1-2sine,

Answers

To find the slope of the tangent line to the polar curve, we need to find the derivative of the equation with respect to θ.

First, we can convert the polar equation into rectangular coordinates using the conversions rcos(θ) = x and rsin(θ) = y:
rcos(θ) = (1-2sin(θ))cos(θ)
r = x/cos(θ)
x/cos(θ) = 1 - 2sin(θ)
x = cos(θ) - 2sin(θ)cos(θ)
y = sin(θ) - 2sin^2(θ)

Next, we can find the derivative of y with respect to x using the chain rule:
dy/dx = (dy/dθ) / (dx/dθ)
dy/dθ = cos(θ) - 4sin(θ)cos(θ)
dx/dθ = -sin(θ) - 2cos^2(θ)
Plugging in the value of e for θ, we get:
dy/dθ = cos(e) - 4sin(e)cos(e)
dx/dθ = -sin(e) - 2cos^2(e)

Finally, we can find the slope of the tangent line by taking the ratio of dy/dθ to dx/dθ:
slope = (cos(e) - 4sin(e)cos(e)) / (-sin(e) - 2cos^2(e))
This is the slope of the tangent line to the polar curve at the point specified by the value of e.
Hi! I'd be happy to help you with your question. To find the slope of the tangent line to the polar curve r = 1 - 2sin(θ) at a specific value of θ, we'll first need to convert the polar equation into Cartesian coordinates.
Let's recall the conversion formulas:
x = r*cos(θ)
y = r*sin(θ)

Now, substitute the polar curve equation into these formulas:
x = (1 - 2sin(θ))*cos(θ)
y = (1 - 2sin(θ))*sin(θ)
To find the slope, we need the derivative of y with respect to x, which is dy/dx. To do this, we'll first find dy/dθ and dx/dθ.
Differentiating both x and y with respect to θ:
dx/dθ = -2cos(θ)^2 + 2sin(θ)cos(θ)
dy/dθ = -2sin(θ)^2 + 2sin(θ) - 2sin(θ)cos(θ)
Now, we find the derivative of y with respect to x:
dy/dx = (dy/dθ) / (dx/dθ)
dy/dx = (-2sin(θ)^2 + 2sin(θ) - 2sin(θ)cos(θ)) / (-2cos(θ)^2 + 2sin(θ)cos(θ))

Now, you can plug in the specific value of θ for which you want to find the slope of the tangent line to the polar curve, and simplify the expression to obtain the final answer.

(1 point) Evaluate the integral by reversing the order of integration. 7 STE dedy

Answers

the integral by reversing the order of integration. the result will be F(β) - F(α), which is the integral evaluated after reversing the order of integration.

First, let's rewrite your integral more clearly:

∫∫ R 7x dy dx, where R is the region of integration.

To reverse the order of integration, we first need to determine the limits of integration for R in terms of x and y. Let's assume the current limits are a to b for x and c(y) to d(y) for y.

Now, we need to express these limits in terms of y and x. Let's denote the new limits as α to β for y and γ(x) to δ(x) for x.

After finding the new limits, we can rewrite the integral as:

∫∫ R 7x dx dy

Now, evaluate the integral by integrating first with respect to x and then with respect to y:

1. Integrate 7x with respect to x: (7/2)x^2 + C₁(x)
2. Apply the limits of integration for x: [(7/2)δ(x)^2 + C₁(δ(x))] - [(7/2)γ(x)^2 + C₁(γ(x))]
3. Integrate the result with respect to y: ∫[α, β] [(7/2)(δ(y)^2 - γ(y)^2)] dy
4. Apply the limits of integration for y: F(β) - F(α)

The final result will be F(β) - F(α), which is the integral evaluated after reversing the order of integration.

Find the nth Maclaurin polynomial for the fu f(x) = tan x, n = 3 3 = P(x) I

Answers

The 3rd Maclaurin polynomial for f(x) = tan x is P(x) = x + (1/3)x^3.

Recall that the Maclaurin series expansion for tan x is given by:

tan x = x + (1/3)x^3 + (2/15)x^5 + ...

To find the 3rd Maclaurin polynomial, we only need to take the first three terms of the series expansion, since n = 3.

Thus, the 3rd Maclaurin polynomial for f(x) = tan x is given by:

P(x) = x + (1/3)x^3.

Note that the first two terms of the polynomial, x and (1/3)x^3, correspond to the first two terms of the Maclaurin series expansion for tan x.

The third term of the polynomial would correspond to the next term in the series expansion, which is (2/15)x^5. However, since we are only finding the 3rd Maclaurin polynomial, we do not need to include this term.

The amount of time spent practicing shooting free throws and the percentage made in a game

Answers

The relationship between the amount of time spent practicing shooting free throws and the percentage made in a game can be described as a positive correlation.

As a basketball player dedicates more time to practicing free throws, their skill and accuracy in making these shots during a game typically improve.

Consistent practice is crucial for developing muscle memory and fine-tuning shooting techniques, which contribute to a higher success rate in making free throws during games. This increased success rate is reflected in the percentage of free throws made in a game, an essential factor that can influence the outcome of the match.

However, it is important to note that the correlation is not always linear. For example, a player who practices for hours on end may experience diminishing returns due to fatigue or lack of focus. Additionally, other factors such as pressure, game context, and individual differences in learning abilities can affect the percentage of free throws made in a game.

In conclusion, investing time in practicing free throws generally leads to an improvement in a player's in-game performance. While there are external factors that may influence the success rate, the positive correlation between practice time and the percentage of free throws made in a game emphasizes the importance of consistent and focused training for basketball players.
