Answer:
a) s = -16
+ 192t + 96
b) Height of the football after 2 seconds is 448 feet.
ii. The football would not hit the ground after 2 seconds.
Step-by-step explanation:
Given:
s = -16 + 
t + 
where: s is the height of the football above the ground, t is the time, is the initial velocity and is the initial height.
The height of the building = = 192 feet and the initial speed of the ball = = 96 feet per second, then;
s = -16 + 192t + 96
a) The polynomial is given as:
s = -16 + 192t + 96
b) The height of the football when t = 2 seconds is;
s = -16(2) + 192(2) + 96
= -32 + 384 + 96
= -32 + 480
s = 448
The height of the football when t = 2 seconds is 448 feet.
ii. The football would not hit the ground after 2 seconds.

Answer:
$20
Step-by-step explanation:
let 1 meter of sulu = s, lusia has m dollar
7s = m + 1 => m = 7s - 1
5s = m - 5
5s = 7s - 1 - 5
2s = 6
s = 3
m = 7s - 1 = 21 - 1 = 20
Answer:
Step-by-step explanation:
The formula for simple interest I is
I = Prt, where
P = the principal (amount invested)
r = the interest rate per period and
n = the number of periods
In this problem, the interest rate is annual, so n = 1.
We must write the interest rate as a decimal fraction.
Let x = amount of each investment. Then
0.02x = interest at 2 %
0.07x = interest at 7 %
0.09x = interest at 9 %
0.18x = total interest
