in how many months will $8500 grow to $8818.75 at 5% P.A?

a) An exponential equation in the form of y = a(b)ˣ that can model the amount of money (future value) in Patrick's account, y, x years after starting the account is y = 894(1.02)ˣ.

b) If Patrick makes no other deposits or withdrawals, after 5 years or approximately 6 years his account will have more than $1,000 (future value).

An exponential equation is a mathematical function, written in the form of y = a(b)ˣ, where y is the ending value, a is the initial value, b is the growth or decay rate, and x is the exponent or number of years.

Thus, there are two types of exponential functions: exponential growth and exponential decay functions.

y = 894(1.02)^6

1,000 ≤ 894(1.02)ˣ

I/Y (Interest per year) = 2%

Present Value = $894

FV (Future Value) ≥ $-1,000

Results:

x = 5.658

x ≈ 6 years

= $1,006.79

Answer:

Step-by-step explanation:

There are 2 parts for your function.    (see image)

y=4x, which is a line with a slope of 4 but x≠0, so there is a hole there

y=1 only at x=0  so the point is above the line

(a)  Domain: All real numbers.  There is a value for all x's

(b)  There is no x-intercept because the graph never touches x

y-intercept (1,0)  That's where the graph touch y

(c) see image

(d) range:  (-∞, 0) U (0, +∞)   there is a stop at 0 for y values

can also be written   -∞<x<1  and 1<x<+∞

(e) yes it's continuous for domain but not range.   because even though there is a jump at that point, i still have an x value.  The jump causes me to not have a y value at y=0, that's why range is discontinuous

The measure of angle x of the circle is x = 5.7

Given data ,

Let the center of the circle be represented as x

Now , the value of x is given by

The measure of angle ∠VWU = 43°

And , the measure of arc VU = ( 7x + 46 )°

Now , from the arc theorem of circle , we get

mVU = 2 ∠VWU

On simplifying , we get

2  ( 43 ) = ( 7x + 46 )

7x + 46 = 86

Subtracting 46 on both sides , we get

7x = 40

Divide by 7 on both sides , we get

x = 5.71

Hence , the measure of x of circle is x = 5.7

The solution set for each rational inequality:

Case 1: - 9 ≤ x < - 5

Case 3: Every real number except x = 1.

In this problem we find two cases of rational inequality, whose solution sets can be found by using algebra properties and sign laws. Now we proceed to solve on each case:

Case 1

(3 · x + 7) / (x + 5) ≥ 5

(3 · x + 7) / (x + 5) - 5 ≥ 0

[(3 · x + 7) - 5 · (x + 5)] / (x + 5) ≥ 0

(- 2 · x + 18) / (x + 5) ≥ 0

- 2 · (x - 9) / (x + 5) ≥ 0

The inequality is positive for - 9 ≤ x < - 5.

Case 3

(- x² - 1) / (- x² + 2 · x - 1) > 0

[(- 1) · (x² + 1)] / [(- 1) · (x² - 2 · x + 1)] > 0

SP = hypotenuse (c) = s

c = s = √50

b = √34

The mean number of processes to be performed before a commercially successful one is 8.

The probability of success in each attempt is 0.125, so the parameter of the geometric distribution is p=0.125.

The mean of a geometric distribution with parameter p is equal to 1/p, so:

Mean = 1/p = 1/0.125 = 8

Therefore, the mean number of processes to be performed before a commercially successful one is 8.

In probability and statistics, the mean (or average) is a measure of the central tendency of a set of numbers. It is calculated by adding up all the numbers in a set and then dividing the sum by the total number of values in the set. The mean is a commonly used measure of the central tendency because it takes into account all the values in the set and provides a single value that represents the "typical" value.

Answer:

2v-1

Step-by-step explanation:

9v+-3v+-4v-2+1

=9v-3v-4v-1

=6v-4v-1

=2v-1

The vector v can be expressed as v = -0.161 i + 0.618 j, where i and j are the unit vectors

To express a vector v in terms of i and j, we need to find its x and y components. The magnitude ||v|| of a vector is given by:

||v|| = √(v₁² + v₂²)

where v₁ and v₂ are the x and y components of v, respectively.

The direction angle θ of a vector with respect to the positive x-axis is given by:

θ = atan(v₂/v₁)

where atan denotes the arctangent function.

In this problem, we are given that the magnitude ||v|| of the vector v is 2/3, and its direction angle θ with respect to the positive x-axis is 116 degrees. Therefore, we can write:

||v|| = √(v₁² + v₂²) = 2/3

θ = atan(v₂/v₁) = 116°

Solving for the x and y components, we get:

v₁ = ||v|| cos(θ) = (2/3) cos(116°) ≈ -0.161

v₂ = ||v|| sin(θ) = (2/3) sin(116°) ≈ 0.618

Therefore, the vector v can be expressed as:

v = -0.161 i + 0.618 j

where i and j are the unit vectors in the x and y directions, respectively.

The equation of the line that is parallel to the line that passes through the point (7, 6) is y = 8x - 50.

A line is an object in geometry that is indefinitely long and has neither breadth nor depth nor curvature.

Since lines can exist embedded in two, three, or higher dimensions environments, they are one-dimensional objects.

The term "line" can also be used to describe a line segment in daily life that contains two locations that serve as its ends.

So, the lines with the same slope but a different y-intercept are said to be parallel.

Therefore, we must use the same slope to plug in the point (7, 6) and solve for the y-intercept.

We thus have:

y = 8x + b

6 = 8(7) + b

6 = 56 + b

b + 56 = 6

b + 56 - 56 = 6 - 56

b = -50

The equation is: y = 8x - 50

Therefore, the equation of the line that is parallel to the line that passes through the point (7, 6) is y = 8x - 50.

Correct question:

Consider the line y = 8x - 4. Find the equation of the line that is parallel to this line and passes through the point (7, 6).

Answer:

21 and 42

Step-by-step explanation:

Lets say x and y are our numbers. x is the smaller number, y is the larger.

We can construct the equations:

x = 0.5y

x + y = 63

Substitute 0.5y for x in the second equation.

0.5y + y = 63

1.5y = 63

y = 42.

Plug y into the first equation.

x = 0.5 * 42

x = 21.

Your numbers are 21 and 42.

Anything between 0 and 1, were 0 traditionally denotes a percentage and 1 typically denotes the degree of certainty, can be used to represent chance. A probability illustration shows the likelihood that a particular event will occur.

The LCD of the rational equation above is 4(x + 7)(x - 7).

To find the LCD (Least Common Denominator) of the given rational equation, we need to factor the denominators of each fraction and then take the product of the highest powers of each factor.

The first denominator, x^2 - 49, can be factored using the difference of squares formula:

x^2 - 49 = (x + 7)(x - 7)

The second denominator, 4x + 28, can be factored by factoring out the greatest common factor:

4x + 28 = 4(x + 7)

Therefore, the LCD is the product of the highest powers of each factor, which is:

LCD = 4(x + 7)(x - 7)

A subscription to a live streaming program normally costs $29 but is on sale for 25% off. An 8% tax is added at checkout then the total cost is $23.49.

To calculate the total cost, first, we find the discounted price of the subscription. A 25% discount on $29 is calculated by multiplying $29 by 0.25 (25% as a decimal), which gives us a discount of $7.25. Subtracting the discount from the original price, we get the discounted price of $29 - $7.25 = $21.75.

Next, we need to add the 8% tax to the discounted price. To calculate the tax amount, we multiply $21.75 by 0.08 (8% as a decimal), which gives us $1.74. Adding this tax amount to the discounted price, we get the total cost as $21.75 + $1.74 = $23.49.

Step 1: Calculate the discount amount:

Discount = 25% of $29

Discount = 0.25 * $29

Discount = $7.25

Step 2: Find the discounted price:

Discounted Price = Original Price - Discount

Discounted Price = $29 - $7.25

Discounted Price = $21.75

Step 3: Calculate the tax amount:

Tax Amount = 8% of Discounted Price

Tax Amount = 0.08 * $21.75

Tax Amount = $1.74

Step 4: Calculate the total cost:

Total Cost = Discounted Price + Tax Amount

Total Cost = $21.75 + $1.74

Total Cost = $23.49

So, the total cost after applying the 25% discount and adding an 8% tax at checkout is $23.49.

- Discount = 0.25 * $29 = $7.25

- Discounted Price = $29 - $7.25 = $21.75

- Tax Amount = 0.08 * $21.75 = $1.74

- Total Cost = $21.75 + $1.74 = $23.49

Wholesale price + (50% x Wholesale price) = $549 + (0.5 x $549) = $823.50

If Josh would receive a 10% discount off the in-store price, then the price he would pay would be:

In-store price - (10% x In-store price) = $823.50 - (0.1 x $823.50) = $741.15

(c) If the superstore marks up the wholesale price of the refrigerator by 40%, then the price at the store would be:

Wholesale price + (40% x Wholesale price) = $549 + (0.4 x $549) = $768.60

Therefore, Josh would pay $768.60 for the refrigerator at the superstore.

Comparing the prices, we can see that Josh would pay less for the refrigerator at the department store after factoring in the discount:
