Answer: 36π
Step-by-step explanation:

Substitute the values of x to the equation of the function f:

Therefore we have two points (-1, 7) and (2, 1).
We can calculate the slope of line l.
The formula of a slope:

Substitute:

<h3>Answer: A) -2.</h3>
Answer:
B
Step-by-step explanation:
The zeros of a polynomial are the solutions to the function. They are found from the factors. The factors which multiply to make the equation in standard form. To write the factors reverse the process by unsolving the factor.
x = -2 comes from x+2
x = 5 comes from x-5
x = 6 comes from x-6
The factored form is (x+2)(x-5)(x-6).
Answer:
Bill got more ($1.62) for each pound exchanged than did Gwyll ($1.56).
Step-by-step explanation:
Let's calculate the unit rate in each case, that is, the number of dollars obtained through exchanging one (1) pound for dollars:
Bill:
$729
--------- = $1.62 per pound
£450
Gwyll:
$780
---------- = $1.56 per pound
£500
Bill got more ($1.62) for each pound exchanged than did Gwyll ($1.56).
