The formula for the volume of a cone is V = r²h, where r is the radius of the
pshichka [43]

Answer:

<u>h = V/r²</u>

Step-by-step explanation:

The formula is :

  • V = r²h (actually 1/3πr²h in real life)

Solving :

  • Dividing both sides by r²
  • V/r² = r²h/r²
  • <u>h = V/r²</u>

I think the correct answers from the choices listed above are the first and the fourth option. The statements that are true about a reflection would be that it  is an isometry and the it flips a plane about a fixed line. <span>A </span>reflection<span> over a line k (notation rk) is a transformation in which each point of the original figure (pre-image) has an image that is the same distance from line k.</span>

A "b" value of less than 1 produces a graph with exponential decay
Andru [333]
<span>If this statement is a True or False question.

Then, TRUE. A "b" value of less than 1 produces a graph with exponential decay.

We consider this formula: y = a*b^x or f(x) =a*b^x

a is the initial value, b is the rate, x is the exponent. 

If b has a value of less than 1, as the exponent increases the resulting value of y decreases.

f(x) = 20(0.90)^x

f(1) = 200(0.90)</span>¹ = 180
f(2) = 200(0.90)² = 162
f(3) = 200(0.90)³ = 145.80
f(4) = 200(0.90)⁴ = 131.22
f(5) = 200(0.90)⁵ = 118.10

Exponential decay is the decrease in a quantity. As you can see in the given example the value of f(x) decreases as the value of x increases because the value of b is less than 1.
