Answer:
Step-by-step explanation:
Let the number of month be x
<u>Expression to show amounts</u>
- 2350 + 200x = 3250 + 175x
- 200x - 175x = 3250 - 2350
- 25x = 900
- x = 900/25
- x = 36
<u>Amount</u>
- 2350 + 200*36 = 2350 + 7200 = 9550
Time is 36 months
Amount is $9550
Answer:
I belive it is the theme that is the most affected.
Step-by-step explanation:
It is 7 .....................................................
Usually, They make tables of equivalent ratios relating quantities with whole-number measurements, find missing values in the tables, and plot the pairs of values on the coordinate plane.
Step-by-step explanation:
initial speed = 272 ft/s
h = -16t² + 272t
a. 1120 = -16t² + 272t we change a bit into
16t² - 272t + 1120 = 0 then divide all with factor 16
t² - 17t + 70 = 0
(t - 10)(t - 7) = 0
t = 10 and t = 7
7 s when it goes up and 10 sec when the rocket goes down.
b. 1152 = -16t² + 272t we change a bit into
16t² - 272t + 1152 = 0 then divide all with factor 16
t² - 17t + 72 = 0
(t - 9)(t - 8) = 0
t = 9 and t = 8 sec
c. since the answer of a and b is:
7 sec and 8 sec the rocket goes up but at 9 sec and 10 sec the rocket goes down then we can take conclusion that the maximum height is reached at 8.5 s
so how long the rocket in the air?
goes up : 8.5 sec
goes down : 8.5 sec
total = 17 sec
