Answer:
B
Step-by-step explanation:
First distribute the 2x to get:
4x² + 10x
Then distribute the -5 to get:
-10x - 25
Then combine
4x² + 10x - 10x - 25
The 10x's will cancel leaving you:
4x² - 25
It can be found by using the formula,
an = a+(n-1)d
Answer:
-3
Step-by-step explanation:
3+x=0
subtract 3 from 3, 0
subtract 3 from 0, -3
The domain is the set of allowed inputs, in this case t values. The smallest t value allowed is t = 0. The largest is t = 165. So that's why the domain is

-------------------------------
The range is

since H = 0 is the smallest output of the function and H = 40,000 is the largest output. Like the domain, the range is the set of possible outputs of a function.
