Answer:
The answer to your question is: letter B
Step-by-step explanation:
Function definition: a function is a relation from a set of inputs to a set of outputs.
The most important about functions is that each input is related to one and only one output. Then there are not repeated values of inputs.
In the exercise, the inputs are -10, -25, -5, and the outputs are 5, 10, 15 and 20.
So, to solve this exercise, look for a number in the options that will not be repeated in the inputs,
Then,
- 20 is a possible option because is not repeated
-5 is not an option to complete the table because 5 already exist.
- 15 is a possible option because is not repeated previously.
Given:
The function is:

To find:
The initial value of the function.
Solution:
We have,

The value of the function at x=0 is called the initial value of the function.
For x=0, we get


Clearly 0.88 is a non zero number and zero to the power of a non zero number is always 1.


Therefore, the initial value of the function is 350.
Answer:
C
Step-by-step explanation:
f(x)=72-4x
72-4x=0
4x=72
x=18
f(x)<=18
The formula to find the surface area of a sphere is A=4(3.14)r². So if you plug in the data you would get,
A=4(3.14)4²
A=(12.56) (16)
A=200.96
You mught want to check over it so you will be able to solve it for yourself the next time you have this question.
Your answer is 80. A triangle’s angles add up to 180 degrees. Therefore, you need to subtract 30 and 70 from 180 to find your answer: 180-(30+70)=80 or 180-70-30=80
