The average price of milk in 2018 was $6.45 per gallon.

The average price of milk in 2021 was $189.15 per gallon.

How to calculate the price

When x = 0 (which represents the year 2018), the function becomes:

3.55 + 2.90(1 + 0)³

= 3.55 + 2.90(1)³

= 3.55 + 2.90

= 6.45

The average price of milk in 2018 was $6.45 per gallon.

When x = 3 (which represents the year 2021), the function becomes:

3.55 + 2.90(1 + 3)³

= 3.55 + 2.90(4)³

= 3.55 + 2.90(64)

= 3.55 + 185.6

= 189.15

The average price of milk in 2021 was $189.15 per gallon.

If arc wvx=(13x+9) and angle wxz=(5x+36) find angle wxy

Answers

Angle WXY is vertical to angle WXZ, they are equal, therefore, angle WXY is also 141 degrees.

How to find the angle WXY using information about the arc WVX and angle WXZ in a circle?

To find the angle WXY, we need to use the properties of angles formed by intersecting chords in a circle. The angles formed by intersecting chords are related to the arcs intercepted by those chords.

Given that the arc WVX is equal to (13x + 9) and the angle WXZ is equal to (5x + 36), we can set up an equation:

Angle WXZ = [tex]\frac{1}{2}[/tex] * Arc WVX

(5x + 36) = [tex]\frac{1}{2}[/tex] * (13x + 9)

To solve for x, we'll multiply both sides of the equation by 2 to eliminate the fraction:

2(5x + 36) = 13x + 9

10x + 72 = 13x + 9

Subtracting 10x and 9 from both sides, we get:

72 - 9 = 13x - 10x

63 = 3x

Dividing both sides by 3, we find:

x = 21

Now that we have the value of x, we can substitute it back into the equation for the angle WXZ to find its value:

Angle WXZ = 5x + 36 = 5(21) + 36 = 105 + 36 = 141 degrees

Since angle WXY is vertical to angle WXZ, they are equal. Therefore, the angle WXY is also 141 degrees.

The faces of a rectangular prism have areas of 9, 9, 25, 25, 49, and 49 square meters. Find the volume of the rectangular prism, in cubic meters

Answers

The volume of the rectangular prism is 105 cubic meters.

To find the volume of the rectangular prism, we can use the formula V = lwh, where V is the volume, l is the length, w is the width, and h is the height.

Since there are three pairs of congruent faces, we can deduce that the areas of the three pairs of faces represent the three dimensions of the rectangular prism. The areas are 9, 25, and 49 square meters, which are the squares of the sides' lengths.

Take the square root of each area to find the corresponding side lengths:

√9 = 3 meters
√25 = 5 meters
√49 = 7 meters

Now, apply the formula to find the volume:

V = lwh = 3 × 5 × 7 = 105 cubic meters.

The volume of the rectangular prism is 105 cubic meters.

6. Yu is considering two different banks for his $3,000 savings account: OPTION A 4% FOR 20 YEARS SIMPLE INTEREST OPTION B 2% FOR 10 YEARS COMPOUND INTEREST 8 What is the interest earned on option A? O What is the total value on option A? What is the interest earned on option B? O What is the total value on option B? 10 Which is the better option?

Answers

The interest earned on Option A is $2400 and Option B is $666.18.  Option A is the better option as Option A has a higher total value of $5400 compared to Option B's total value of $3666.18.

To calculate the interest earned and total value for each option, we can use the following formulas:

For Option A:

- Interest earned = principal x rate x time = 3000 x 0.04 x 20 = $2400

- Total value = principal + interest earned = 3000 + 2400 = $5400

For Option B:

- Interest earned = principal x (1 + rate/n)^(n x time) - principal = 3000 x (1 + 0.02/1)^(1 x 10) - 3000 = $666.18

- Total value = principal + interest earned = 3000 + 666.18 = $3666.18

Therefore, the interest earned and total value for each option are as follows:

Option A:

- Interest earned = $2400

- Total value = $5400

Option B:

- Interest earned = $666.18

- Total value = $3666.18

To compare the two options, we need to consider the total value of each option. Option A has a higher total value of $5400 compared to Option B's total value of $3666.18. Therefore, Option A is the better option.

Answers

The amount of time Carl represent is 25-m on the problems.

The statement "Davis spent 25 minutes working on math problems. Carl worked on math problems for m fewer minutes" means that Carl spent some amount of time working on math problems, but that amount is m minutes less than what Davis spent.

To represent the amount of time Carl worked on math problems, we can use the variable X. We know that X is equal to the amount of time Carl worked on math problems, and that X is equal to 25 minus m.

This is because Davis spent 25 minutes on math problems, and Carl worked on them for m fewer minutes. So if we subtract m from 25, we get the amount of time Carl worked on math problems.

Therefore, the equation X = 25 - m represents the amount of time Carl worked on math problems, where X is the amount of time in minutes and m is the number of minutes Carl worked less than Davis.

Find the radius of gyration of a plate covering the region

(Type exact answer)

Answers

The radius of gyration of the plate about the x-axis is [tex]6 \sqrt{6} / 5[/tex] units.

How to find the radius of gyration of a plate covering the region?

To find the radius of gyration of a plate covering the region bounded by [tex]y = x^2[/tex], x = 6, and the x-axis with respect to the x-axis, we need to use the formula:

[tex]k_x = \sqrt{(I_x / A)}[/tex]

where [tex]k_x[/tex] is the radius of gyration, [tex]I_x[/tex] is the moment of inertia of the plate about the x-axis, and A is the area of the plate.

We can calculate the area A of the plate as follows:

[tex]A = \int\limits^6_0 { x^2}\, dx\\= [x^3/3]\ from\ 0\ to\ 6\\= 72[/tex]

To find the moment of inertia [tex]I_x[/tex], we can use the formula:

[tex]I_x = \int\ {y^2} \, dA[/tex]

where y is the perpendicular distance of an element of area [tex]dA[/tex] from the x-axis. We can express y in terms of x as y = x². Therefore, we have:

[tex]dA = y dx = x^2 dx\\I_x = \int\limits^6_0 { x^2 (x^2)} dx\\= \int\limits^6_0 {x^4}\, dx\\= [x^5/5]\ from\ 0\ to\ 6\\= 6^5/5[/tex]

Substituting these values into the formula for [tex]k_x[/tex], we get:

[tex]k_x = \sqrt{(I_x / A)}\\= \sqrt{((6^5/5) / 72)}\\= \sqrt{(6^3 / 5)}\\= 6 \sqrt{6} / 5[/tex]

Therefore, the radius of gyration of the plate about the x-axis is [tex]6 \sqrt{6}/ 5[/tex] units.

In 3 ​minutes, a conveyor belt moves 200 pounds of recyclable aluminum from the delivery truck to a storage area. A smaller belt moves the same quantity of cans the same distance in 9 minutes. If both belts are​ used, find how long it takes to move the cans to the storage area

Answers

If both belts are​ used, it will take 2.25 minutes to move the cans to the storage area

To solve this problem, we need to use the concept of rate of work. We know that the larger belt can move 200 pounds of aluminum in 3 minutes, which means its rate of work is 200/3 = 66.67 pounds per minute. Similarly, the smaller belt can move the same quantity of cans in 9 minutes, which means its rate of work is 200/9 = 22.22 pounds per minute.

When both belts are used together, their rates of work add up, so the total rate of work is 66.67 + 22.22 = 88.89 pounds per minute. We can use this rate of work to find how long it will take to move the cans to the storage area.

Let's assume that it takes x minutes to move the cans using both belts. Then, we can set up the following equation:

88.89x = 200

Solving for x, we get:

x = 2.25 minutes

Therefore, it will take 2.25 minutes to move the cans to the storage area using both belts.

cap A times open paren negative 7 comma negative 5 close paren

Answers

The coordinates of point P along the directed line segment AB with a ratio of 1:4 are (-5, -2).

Since the ratio of AP to PB is 1:4, we can use the midpoint formula to find the coordinates of point A. The midpoint formula is

((x₁ + x₂)/2, (y₁ + y₂)/2)

Plugging in the coordinates of points P and B, we get:

((4(-7) - 2)/5, (4(-5) + 0)/5) = (-30/5, -20/5) = (-6, -4)

we can use the point-slope formula to find the equation of the line segment AB:

(y - (-4)) = (1/5)(x - (-6))

Simplifying this equation, we get:

y = (1/5)x + 2

Finally, we can use the given ratio of 1:4 to find the coordinates of point P. Since the ratio of AP to PB is 1:4, we can use the ratio formula to find the coordinates of point P:

(x, y) = (4(-5) + (-2))/5, (4(-2) - (-4))/5) = (-30/5, 12/5) = (-6, 2.4)

Rounding off to one decimal place, we get the coordinates of point P as (-5, -2).

Find the volume of the solid obtailed by rotating the region bounded by the given curves about the specified axis. y= x, y = 1 about y = 3

Answers

The region bounded by the given curves is a triangle with vertices at (0,0), (1,1), and (1,0). When this region is revolved around the line y=3, we obtain a solid with a hole in the middle.
To find the volume of this solid, we can use the method of cylindrical shells. Imagine slicing the solid into thin cylindrical shells with radius r and height Δy. The volume of each shell is approximately 2πrΔy times the thickness of the shell.

The distance between the axis of rotation (y=3) and the line y=1 is 2 units. Therefore, the radius of each cylindrical shell is r = 3 - y. The height of each shell is Δy = dx, where x is the distance from the y-axis.

To set up the integral, we need to express x in terms of y. Since the region is bounded by y=x and y=1, we have x=y for 0<=y<=1. Therefore, the integral for the volume of the solid is:
V = ∫[0,1] 2π(3-y)x dx
 = 2π ∫[0,1] (3-y)y dx

Evaluating this integral, we get:
V = 2π [3y^2/2 - y^3/3] from 0 to 1
 = 2π (3/2 - 1/3)
 = 2π/3

Therefore, the volume of the solid obtained by rotating the region bounded by y=x, y=1 about y=3 is (2/3)π cubic units.

What is addition?

The phrase "the addition" refers to combining two or more numbers. Adding two numbers is indicated by the plus sign (+), therefore adding three is written as three plus three.

To add 8 and 78, we can start by adding the ones place digits, which are 8 and 7.

8 + 7 = 15

Since 15 is greater than 10, we need to regroup 10 ones as 1 ten and carry it over to the tens place. We can represent this with place value blocks by moving a rod of 10 ones from the ones place to the tens place.

So we have:

We have to find out how many quarters Caleb has.

Let x be nickel,

y be dimes and

z be quarters

x + y + z = 51.....(1)

1 quartes = 25 cents

1 dimes = 10 cents

1 nickel = 5 cents

Now, the total dollar is $9,

Where the function f(x) = x² + 2x - 3 is given, note that the x-intercepts of the function f(x) are -3 and 1, and the minimum value of the function is -4. See the attached graph.

What is the explanation for the above response?



To find the minimum and maximum points of the function f(x), we can complete the square:

f(x) = x^2 + 2x - 3

= (x + 1)^2 - 4

We can see that the function is in the vertex form f(x) = a(x - h)^2 + k, where the vertex is (-1, -4).

Since the coefficient of the x^2 term is positive, the parabola opens upwards, and the vertex is the minimum point. Therefore, the minimum value of the function f(x) is -4.

To find the x-intercepts, we can set f(x) = 0:

(x + 1)^2 - 4 = 0

(x + 1)^2 = 4

Taking the square root of both sides, we get:

x + 1 = ±2

x = -1 ± 2

Therefore, the x-intercepts of the function f(x) are x = -3 and x = 1.

In summary, the x-intercepts of the function f(x) are -3 and 1, and the minimum value of the function is -4, which occurs at the vertex (-1, -4).

3. Compute the integral JSS, udv, where U is the part of the ball of radius 3, centered at 0,0,0), that lies in the 1st octant. Recall that the first octant is the part of the 3d space where all three coordinates I, y, z are nonnegative. (Hint: You may use cylindrical or spherical coordinates for this computation, but note that the computation with cylindrical coordinates will involve a trigonometric substitution - 30 spherical cooridnates should be preferable.)

Answers

To compute the integral JSS, udv, where U is the part of the ball of radius 3, centered at 0,0,0), that lies in the 1st octant, we can use spherical coordinates. Since the region is defined as having all three coordinates nonnegative, we can set our limits of integration as follows: 0 ≤ ρ ≤ 3, 0 ≤ θ ≤ π/2, and 0 ≤ φ ≤ π/2.

Using the Jacobian transformation, we have:

JSS, udv = ∫∫∫U ρ²sinφ dρdθdφ

Substituting in our limits of integration, we get:

JSS, udv = ∫0^π/2 ∫0^π/2 ∫0³ ρ²sinφ dρdθdφ

Evaluating the integral, we get:

JSS, udv = (3³/3) [(sin(π/2) - sin(0))] [(1/2) (π/2 - 0)]

JSS, udv = 9/2 π

Therefore, the value of the integral JSS, udv, over the part of the ball of radius 3 that lies in the 1st octant is 9/2π.
To compute the integral JSS, udv, over the region U, which is the part of the ball of radius 3 centered at (0,0,0) and lies in the first octant, we will use spherical coordinates for this computation as it's more preferable.

In spherical coordinates, the volume element is given by dv = ρ² * sin(φ) * dρ * dφ * dθ, where ρ is the radial distance, φ is the polar angle (between 0 and π/2 for the first octant), and θ is the azimuthal angle (between 0 and π/2 for the first octant).

Now, we need to set up the integral for the volume of the region U:
JSS, udv = ∫∫∫ (ρ² * sin(φ) * dρ * dφ * dθ), with limits of integration as follows:
ρ: 0 to 3 (radius of the ball),
φ: 0 to π/2 (for the first octant),
θ: 0 to π/2 (for the first octant).

So, the integral becomes:
JSS, udv = ∫(0 to π/2) ∫(0 to π/2) ∫(0 to 3) (ρ² * sin(φ) * dρ * dφ * dθ)

By evaluating this integral, we will obtain the volume of the region U in the first octant.

Urgenttttt what is true about the series given: 25+5+1+...

the series converges to 31.25 the series diverges .
the series converges to 125
the series does not converge or diverge .

Answers

The statement "the series converges to 31.25" is true about the given series.

Given series is 25 + 5 + 1 + ....

We can clearly see that given series is infinite geometric series.

First term is a=25

common ratio is r = 5/25

= 1/5

We know that the formula of sum of an infinite geometric series is

S = a / (1 - r)

S = 25 / (1 - 1/5)

S = 25/(4/5)

S = (25*5)/4

S = 125/4

S = 31.5

Therefore, the sum of the infinite geometric series is 31.25.

Since, the sum of the series is a finite number, we can say that the series converges.

Therefore, the statement "the series converges to 31.25" is true about the given series.

A hot water pipe needs to be insulated to prevent heat loss. The outer pipe has a diameter D = 48.7 cm (correct to 3 significant figures). The inner pipe has a diameter d = 19.25 cm (correct to 2 decimal places). Work out the upper and lower bound of the cross-sectional area of the insulation, A (the shaded area between the inner and outer pipes) in cm2 to the nearest whole number. Give your answer in interval form, using A as the variable.

Answers

The upper and lower bound of the cross-sectional area of the insulation, would be A = [ 3129, 3137 ] cm².

How to find the upper and lower bond ?

The upper and lower bound of A would be found by the formula :

A = π x ( R ² - r ² )

The upper bound is therefore:

= π x  (( 48. 75 / 2) ² - ( 19.2 45 / 2) ²)

= π x ( 1183. 0625 - 184. 857025 )

= π x 998. 205475

= 3, 137 cm²

The lower bound will then be:

= π x ( ( 48. 65 / 2 ) ²- (19. 255 / 2) ²)

= π x ( 1180. 9225 - 184. 963025)

= π x 995. 959475

= 3, 129 cm²

The interval form is therefore A = [ 3129, 3137 ] cm²

A basic pattern of 1 blue bead and 1 green bead is used to make a bracelet that is 37cm long. The bracelet is made by repeating the basic pattern 10 times. The length of a blue bead is Bcm. The length of a green bead is 1. 2cm. Complete the question to represent the length of the bracelet

Answers

Answer: Therefore, the length of a blue bead is 2.5 cm, and the length of a green bead is 1.2 cm. And the length of the bracelet is:

10 × (2.5 + 1.2) = 37 cm.

Step-by-step explanation:

To represent the length of the bracelet, we need to determine the length of each repetition of the basic pattern and then multiply it by the number of times the pattern is repeated.

The length of each repetition of the basic pattern is the sum of the length of one blue bead and one green bead, which is:

B + 1.2 cm

Since the basic pattern is repeated 10 times, the total length of the bracelet is:

10 × (B + 1.2) cm

And we know that the total length of the bracelet is 37 cm, so we can set up an equation:

10 × (B + 1.2) = 37

Simplifying the equation, we can divide both sides by 10:

B + 1.2 = 3.7

Subtracting 1.2 from both sides, we get:

B = 2.5

Therefore, the length of a blue bead is 2.5 cm, and the length of a green bead is 1.2 cm. And the length of the bracelet is:

10 × (2.5 + 1.2) = 37 cm.

tomas earns 0.5% commision on the sale price of a new car. On wednesday, he sells a new car for $24,500. How much commison does tomas earn on this sale

Answers

Tomas earns a commission of $122.50 on the sale of the new car.

Tomas earns a 0.5% commission on the sale price of a new car. On Wednesday, he sells a new car for $24,500. To determine the commission Tomas earns, we need to multiply the sale price by the commission rate. The commission rate is given as 0.5%, which can be expressed as a decimal by dividing by 100. So, 0.5% is equal to 0.005 as a decimal.

Now, we can calculate Tomas's commission by multiplying the sale price by the commission rate. In this case, we multiply $24,500 by 0.005:

$24,500 x 0.005 = $122.50

7*. All lengths are in cm. Find the area of the right angled
triangle.
x-14( shortest side)
2x+5( hypotenuse)
2x+3( remaining side)

Answers

Answer:

504 cm^2.

Step-by-step explanation:

By Pythagoras:

(2x + 5)^2 = (2x + 3)^2 + (x - 14)^2

4x^2 + 20x + 25 = 4x^2 + 12x + 9 + x^2 - 28x + 196

20x - 12x + 28x + 25 - 9 - 196 = x^2

x^2 - 36x + 180 = 0

(x - 6)(x - 30) = 0

x = 6, 30.

As one of the sides is x - 14, x mst be 30 as its length has to be positive.

So the area of the triangle

= 1/2 * (x - 14) 8 (2x + 3)

= 1/2 * (30-14)(60 + 3)

= 1/2 * 16 * 63

= 504 cm^2.
