Answer:
(d) -11
Step-by-step explanation:
Each of the functions is evaluated in the usual way: put the number where the variable is in the expression and simplify.
h(-1) = -2(-1)² -3(-1) +1 = -2 +3 +1 = 2
f(2) = (2(2) +7)/(2 -3) = 11/-1 = -11
Then f(h(-1)) is ...
f(h(-1)) = f(2) = -11

Step-by-step explanation:
Answer:
a) $300 in interest
b) $1800 account total
Step-by-step explanation:
Interest = Principal x Rate x Time
I = 1500(.04)(5)
I = 300
A = P + I
1800 = 1500 + 300
First of all, remember if 2 people are walking away from each other at the same speed (ex 4 mph), after 1 mile, they would be 8 miles away. 4 miles south and north. So these trains go away from each other at a total of 150 mph( 67 + 83). So your equation is h = hours, 150h = 600. Divide both sides by 150 to get h = 4. 4 hours is your answer.
