Answer:

The diameter decreases at a rate of 0.053 cm/min.

Step-by-step explanation:

Surface area of an snowball

The surface area of an snowball has the following equation:

[tex]S_{a} = \pi d^2[/tex]

In which d is the diameter.

Implicit differentiation:

To solve this question, we differentiate the equation for the surface area implictly, in function of t. So

[tex]\frac{dS_{a}}{dt} = 2d\pi\frac{dd}{dt}[/tex]

Surface area decreases at a rate of 3 cm2/min

This means that [tex]\frac{dS_{a}}{dt} = -3[/tex]

Tind the rate (in cm/min) at which the diameter decreases when the diameter is 9 cm.

This is [tex]\frac{dd}{dt}[/tex] when [tex]d = 9[/tex]. So

[tex]\frac{dS_{a}}{dt} = 2d\pi\frac{dd}{dt}[/tex]

[tex]-3 = 2*9\pi\frac{dd}{dt}[/tex]

[tex]\frac{dd}{dt} = -\frac{3}{18\pi}[/tex]

[tex]\frac{dd}{dt} = -0.053[/tex]

The diameter decreases at a rate of 0.053 cm/min.

Step-by-step explanation:

[tex] - 12u + 13 = 8w - 3 \\ - 12u + 13 + 3 = 8w \\ - 12u + 16 = 8w \\ w = \frac{ - 12u + 16}{8} \\ w = \frac{ - 3}{2} u + 2[/tex]

I hope that is useful for you :)

Answer:

6

Step-by-step explanation:

2(2y - 12) = 0

distribute the 2

2·2y - 2·12 = 0

4y - 24 = 0

add 24 to both sides

4y - 24 + 24 = 0 + 24

4y = 24

divide both sides by 4

(4y)/4 = 24/4

y = 6

How many days will it take for the water to be 4m high?

Step-by-step explanation:

use the missing variable.

The volume of the solid obtained by rotating the region under the curve over the interval [4, 7] about the x-axis is approximately 111.817 cubic units.

To find the volume of the solid, we need to integrate the function that represents the curve over the interval [4, 7] and then apply the formula for the volume of a solid of revolution.

Let's assume the function that represents the curve is f(x). We want to rotate the region under the curve from x = 4 to x = 7 about the x-axis.

The formula for the volume of a solid of revolution is given by:

[tex]V = \pi \int\limits^a_b { (f(x))^2} \, dx[/tex]

In this case, a = 4 and b = 7, so the formula becomes:

In this case, a = 4 and b = 7, so the formula becomes:

[tex]V = \pi \int\limits^4_7 { (f(x))^2} \, dx[/tex]

To calculate the integral, we need to know the specific function f(x). Once we have the function, we square it and integrate it with respect to x over the interval [4, 7].

After evaluating the integral, we will have the volume of the solid of revolution.

Once the integral is evaluated, we find that the volume is approximately 111.817 cubic units.

Answer:

You would pay 80% of the cost of a large pizza. So if the pizza was $10 you would pay $8 getting $2 off.

Step-by-step explanation:

Answer:

A) 9(2+7)

B) 3(12+9

C) 8(3+7)

D)4(5+8)

Step-by-step explanation:

A)

9*(x+7) = 18+63

9*(x+7) = 81

81/9 = x+7

9 = x+7

x = 2

B)

x*(12+9) = 36+27

x*(12+9) = 63

x*21 = 63

x = 63/21

x = 3

C)

8*(x+7) = 24+56

8*(x+7) = 80

x+7 = 80/8

x+7 = 10

x = 3

D)

x*(5+8) = 20+32

x*13 = 52

x = 52/13

Step-by-step explanation:

Let d represent the length of the track in meters. The relation of interest is ...

  time = distance/speed

Then the total time to run and walk back is ...

  60 = d/10 + d/5

  600 = d + 2d

  200 = d . . . . . . . divide by 3

The length of the track is 200 meters.

Answer:

4 units

Step-by-step explanation:

Use the distance formula

d = [tex]\sqrt{(x2 - x1)^2 + (y2 - y1)^2}[/tex]

Plug in the points

d = [tex]\sqrt{(-4 - (-8))^2 + (3 - 3)^2}[/tex]

d = [tex]\sqrt{(4)^2 + (0)^2}[/tex]

d = [tex]\sqrt{16}[/tex]

d = 4

So, the distance between the pair of points is 4 units

Answer:

4 units

Step-by-step explanation:

[tex]\large{ \sqrt{ {(x_2 - x_1)}^{2} + {(y_2 - y_1)}^{2} } }[/tex]

The formula above is the formula of distance between two points.

Substitute the ordered pairs in.

[tex] \large{ \sqrt{ {( - 4 + 8)}^{2} + {(3 - 3)}^{2} } } \\ \large{ \sqrt{ {4}^{2} + 0 } } = \sqrt{16} = 4[/tex]

Therefore, the distance between two points is 4 units.
