Answer:
The movers will need 3 crib-jacks
Step-by-step explanation:
Since each crib jack can lift 30,000lbs, and without the belongings it only weighs 90,000, which divided by 30,000 equals 3.
The solve for n would be 11
2 to the second power is 4 and 4x11=44
From birth to 5yo = 91,200
from 5 to 18yo = 167,000
therefore from birth to 18yo will cost 91,200 + 167,000 which is 258,200
Since the question says per year and thats the total cost of 18 years ( from 0 years to 18), we divide it by 18.
258,200 ÷ 18 = 14,344
Answer a: 14,344
7*8-4(6-2)+18
56-4(4)+18
56-16+18
40+18
58
6^2-(8*3)+2^2(7*3)
36-24+4(21)
12+84
96
(5,0) if it’s asking the solution or do you want the equation? Technically the solution would be where the parabola touched the x axis
