Answers

Answer:

C.) No solution

Step-by-step explanation:

3y=3/2x+6

Just divide 3 by both sides.

3/2 divided by 3/1
3/2 * 1/3 = 1/2

y = 1/2x + 2 is the solution

SOLVE for r.
V=(1/3)pi r^2 h

Answers

V=(1/3)pi r^2 h
3V = pi r^2 h
3V/pi = r^2 h
3V/h*pi = r^2
r = sqrt (3V/h*pi)

sand is falling at the rate 27 cubic feet per minute onto a conical pile whose radius is always equal to its height. how fast is the height of the pile growing when the height is exactly (a) 3 feet (b) 6 feet (c) 9 feet.

Answers

Answer:

Step-by-step explanation:

The formula for the volume of a cone is V = (1/3)(area of base)(height). If the radius is always equal to the height of the cone, then V = (1/3)(πh²)(h), where we have eliminated r. Shortened, this comes out to V = (1/3)(π)(h³).

We want to know how fast h is increasing when h = 3 ft.

Taking the derivative dV/dt, we get dV/dt = (1/3)π(3h²)(dh/dt), or, in simpler terms, dV/dt = πh²(dh/dt). Set this derivative = to 27 ft³/min and set h = 3 ft.

Then 27 ft³/min = π(3 ft)²(dh/dt) and solve for dh/dt: (3/π) ft/min = dh/dt when h = 3 ft.

Answer:

Step-by-step explanation:

20. First find the values of the numbers being added.

$((3)/(4))^3 = (27)/(64)$

$((5)/(8) )^2 = (25)/(64)$

These numbers have a common denominator, so you can add the numerators

27 + 25 = 52

so the number comes out to $(52)/(64)$

to simplify, divide the numerator and denominator by 4.

So the final fraction becomes $(13)/(16)$

However the question doesn't have this answer and now I am confused. I assumed that the expression was $r^(3)+s^(2)$ but the picture is a little bit blurry and I have bad eyesight so let me know if it is not. I'm too tired to delete this so next problem.
