We calculate for the volumes of each of the wax needed for the candles through the equations presented below.

For cylinder:
V = πr²h
where V is volume, r is radius and h is height.

Substituting the known values,

V = (3.14)(3 in)²(6 in)
V = 169.56 in³

For sphere:

V = 4πr³/3
Substituting the known values,
V = 4(3.14)(3 in)³ / 3 = 113.04 in³

The difference between the two volumes,

difference of volumes = 169.56 in³ - 113.04 in³
difference of volumes = 56.52 in³

Thus, the answer to this item is the last choice.

Evaluate f (2) if f (x)= 10-x^3

weeeeeb [17]

f (x)= 10-x³.
f(2) means the value of the function when x=2.
So, we need to substitute 2 instead of x.

f(2) = 10 - 2³ = 10-8 =2

f(2) = 2

What are the domain and range of an exponential parent function? Help please

a_sh-v [17]

The domain and the range of an exponential parent function, that is, y = eˣ are equal to all real numbers and non-negative numbers, respectively. (Correct choice: C)

<h3>How to determine the domain and range of an exponential function</h3>

In this problem we should determine what an exponential parent function is. The most common exponential functions have the following form:

$y = A\cdot e^{B\cdot x} + C$ (1)

(1) is an exponential parent function for A = 1, B = 1 and C = 0.

All functions are relations with a domain and range, the domain is an input set related to the range, that is, an output set. In the case of an exponential parent function, the domain and the range of the expression are $\mathbb{R}$ and y ≥ 0, respectively. (Correct choice: C)

A coin is tossed and a standard number cube is rolled. What is the probability that the coin shows head and the number cube show

krok68 [10]

The total possibility that the head and even no on dice appears is 3. and total possible choice are 12 {head ---> (1,2,3,4,5,6) & tail ---> (1,2,3,4,5,6)}. so the probability is 3/12= 1/4.

C: 1/4
