The radius of a right circular cone is increasing at a rate of 1.9 in/s while its height is decreasing at a rate of 2.2 in/s. At

musickatia [10]

Answer:

Volume of the cone is increasing at the rate $9916\pi \frac{in^3}{s}$ .

Step-by-step explanation:

Given: The radius of a right circular cone is increasing at a rate of $1.9$ in/s while its height is decreasing at a rate of $2.2$ in/s.

To find: The rate at which volume of the cone changing when the radius is $134$ in. and the height is $136$ in.

Solution:

We have,

$\frac{dr}{dt} =1.9 \:\text{in/s}$ , $\frac{dh}{dt}=-2.2\:\text{in/s}$ , $r=134 \:\text{in}$ , $h=136\:\text{in}$

Now, let $V$ be the volume of the cone.

So, $V=\frac{1}{3}\pi r^{2}h$

Differentiate with respect to $t$ .

$\frac{dv}{dt} =\frac{1}{3}\pi \left [ r^2\frac{dh}{dt}+h\left ( 2r \right )\frac{dr}{dt} \right ]$

Now, on substituting the values, we get

$\frac{dv}{dt} =\frac{1}{3}\pi\left [ \left ( 134 \right )^2\left ( -2.2 \right )+\left ( 136\right )\left ( 2 \right )\left ( 134 \right )\left ( 1.9 \right ) \right ]$

$\frac{dv}{dt} =\frac{1}{3}\pi\left [ -39503.2+69251.2 \right ]$

$\frac{dv}{dt} =\frac{1}{3}\pi\left [ 29748 \right ]$

$\frac{dv}{dt} =9916\pi \frac{in^3}{s}$

Hence, the volume of the cone is increasing at the rate $9916\pi \frac{in^3}{s}$ .

At George Washington High School the ratio of graduating seniors that go on to college, as compared to those who do not, is 7 :

soldi70 [24.7K]

First you figure out that the ratio 7:4 is 1.75
Then you do this problem 28 divided by 1.75=16
And 28:16 is the same as 7:4
Now all you do is add 28+16=44

What value represents the vertical translation from the graph of the parent function f(x) = x2 to the graph of the function

Vlad [161]

A function is shifted vertically upwards/downwards by adding/subtracting a constant value to the function.

In this case f(x) was shifted upwards by 3 units.

An isosceles triangle whose equal sides measure 8 and whose altitude drawn to the base measures 8

viva [34]

The question is incomplete, the complete question is here

Find the measures of the angles of an isosceles triangle whose equal sides measure 8 and whose altitude drawn to the base measures 4

Answer:

The measures of the angles of the isosceles triangle are 30°, 30° and 120°

Step-by-step explanation:

In a triangle whose sides a, b, c and angles A, B and C, where a is opposite to ∠A, b is opposite to ∠B, and c is opposite to ∠C, the given is

a = c
m∠A = m∠C

The height from ∠B to side b is 4 units

That means the length of the height is half the length of each equal sides, then there is a right triangle its hypotenuse is 8 and the side opposite to the base angle is 4, so we can find the measure of the base angle by using the rule sin(base angle) = $\frac{altitude}{a}$

∵ The base angles are ∠A and ∠C

∵ a = c = 8

∵ The altitude to b is 4

∵ $sin(A)=\frac{4}{8}=\frac{1}{2}$

- By using $sin^{-1}$

∴ m∠A = $sin^{-1}(\frac{1}{2})$

∴ m∠A = 30°

∵ m∠A = m∠C

∴ m∠C = 30°

Use the rule of the sum of the measures of the interior angle of a Δ is 180° to find m∠B

∵ m∠A + m∠C + m∠B = 180

∵ m∠A = m∠C = 30°

∴ 30° + 30° + m∠B = 180°

∴ 60 + m∠B = 180

- Subtract 60 from both sides

∴ m∠B = 120°

The measures of the angles of the isosceles triangle are 30°, 30° and 120°
