Answer:
x ∈ R, x ≠ 9
Step-by-step explanation:
Given
f(x) =
The denominator of f(x) cannot be zero as this would make f(x) undefined.
To find the value that x cannot be, equate the denominator to zero and solve for x
x - 9 = 0 ⇒ x = 9 ← excluded value
Thus the domain is x ∈ R, x ≠ 9
The equation that represents the mathematical statement is 2^x + 1 = 21
<h3>How to determine the equation?</h3>
The statement is given as:
Two to the second power +1 equals 21
Equals mean =
So, we have:
Two to the second power +1 = 21
Two to the second power means 2^x, where x is the variable.
So, we have
2^x + 1 = 21
Hence, the equation that represents the statement is 2^x + 1 = 21

Is there supposed to be a picture or a multi choice answer because there is none.Sorry
A) Yes, the smaller cone is similar to the original cone. They are similar because the smaller cone is half of the original cone.
B) The volume of the larger cone is 56.52 and the volume for the smaller cone is 7.065
C) The ratio of the volume of the larger cone and the smaller cone is the top/smaller cone is half the volume of the bottom/larger cone
D) The Volume of the frustum is 49.455
The expected winning on an $1 ticket would be $0.326 or about 33 cents.
First, we need to find the total of all of the prize money:
1(160000) + 2(20000) + 11(4000) + 21(800) = 260800
Divide this total by the 800,000 tickets and you get 0.326.
