Answer:
(a) $126
(b) .453333%
Step-by-step explanation:
(a) 476 - 350 = $126
(b)

Simplif 1/2t to t/2
t/2 + 8 = 5/2t - 10
Simplify 5/2t to 5t/2
t/2 + 8 = 5t/2 - 10
Multiply both sides by 2
t + 16 = 5t - 20
Subtract t from both sides
16 = 5t - 20 - t
Simplify 5t - 20 - t to 4t - 20
16 = 4t - 20
Add 20 to both sides
16 + 20 = 4t
Simplify 16 + 20 to 36
36 = 4t
Divide both sides by 4
36/4 = t
Simplify 36/4 to 9
9 = t
Switch sides
<u>t = 9</u>
Answer:
Right now it would be

Since desend means down add -20 to -40

or

Then is goes up 35, which is positive

Therefore, the answer is -25

Hello,
A)
h max
A:-2x/100+32/100=0==>x=16
B:-2x/100+18/100=0==>x=9
B)
y=0
A:-x²+32x+400=0==>x=41.612496... or x=-9.61... exclude
B:-x²+18x+500=0 ==> x=28.1039415...or x=-15.1039.. exclude
C)
x=0
A:y=4
B:y=5
D)-x²/100+32/100x+4=-x²/100+18/100x+5
==>14/100*x=1 ==>x=50/7=7.1428....
