Answer: 3 seconds
Step-by-step explanation:
Hi, the correct equation is d (t) = 144- 16 t²
So, to answer this question we have to analyze the information given:
When the car reaches the ground the distance, d (t) of the car from the ground is 0.
0 = 144- 16 t²
Solving for t:
16 t² =144
t²=144/16
t²= 9
t = √9
t = 3 seconds

Answer:
A. 13.5ft
Step-by-step explanation:
Answer:
R___S___T
RT=RS+ST
(17y-33) =( 9y+3)+(3y+4)
17y-33 = 12y+ 7
17y - 12y = 7+33
5y= 40
y=40/5
y= 8
RS = 9y+3 = 9(8)+3= 72+3=75
ST= 3y+4 = 3(8)+4=24+4=28
RT= 17y-33= 17(8)-33= 136-33= 103 —>
<u>Or</u><u> </u><u>;</u> RT=RS+ST =75+28= 103
<h3><u>So</u><u>;</u></h3><h3>a. <u>Ans;</u> y=8</h3>
<h3>b. <u>Ans;</u> RS= 75 , ST = 28 , RT = 103</h3>
