If a snowball melts so that its surface area decreases at a rate of 3 cm2/min, find the rate (in cm/min) at which the diameter decreases when the diameter is 9 cm. (Round your answer to three decimal places.)
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:
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)

please help
Answer:
Least = m<H
Middle = m<J
Greatest = m<I
Step-by-step explanation:
The angle opposite the shortest side would have the shortest angle. The side opposite the greatest side would have the greatest angle.
Least = m<H
Middle = m<J
Greatest = m<I

Given two similar triangles.
Corresponding parts of similar figures have same ratio.
Use ratios to find the value of x:
(4x - 5)/(x + 7) = 35/12.5(4x - 5)/(x + 7) = 14/55(4x - 5) = 14(x + 7)20x - 25 = 14x + 9820x - 14x = 98 + 256x = 123x = 123/6x = 20.5Find the value of FG:
FG = 4*20.5 - 5 = 77Karin has 7 more pieces of candy than Danny. Danny has d pieces of candy. Karin uses the expression 7 + d to figure out how many pieces of candy she has.

Find the distance between the pair of points.
(-4,3) and (-8,3)
The distance between the pair of points is
units.
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.

Step-by-step explanation:
Answer:
The answer is (C) y = 55 + 15 x
Step-by-step explanation:
This is because the cost of the plan must be added to the cost of the lines to find the total cost. The equation for option (C) correctly depicts that y the plan, needs to be added to x the lines. This equation correctly shows the relationship between the two numbers.

HELP. What is the value of y in the equation 2(2y - 12) = 0? (5 points)
1) 4
12 6
3
3) 7
4) 8
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

(q12) Find the volume of the solid obtained by rotating the region under the curve
over the interval [4, 7] that will be rotated about the x-axis.
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.
