Step-by-step explanation:
BD = 14.5
Answer:
n/a
Step-by-step explanation:
A. t(h) = 5.5h + 50
B. t(6) = 5.5(6) + 50
t(6) = 85
C. (6, 85) This means that when the electrician for 7 hours, they get paid $85
F(x) = -3(x + 2)(x - 5)^3 > 0
(x + 2)(x - 5) > 0
x + 2 > 0 or x - 5 < 0
x > -2 or x < 5
-2 < x < 5
Therefore, the stated interval is false.
For this case, the first thing we must do is define variables.
We have then:
x: number of minutes
y: final temperature
We write then the equation that models the problem:

For y = 20 we have:

Clearing x:
