Answer:
2s or 3s
Step-by-step explanation:
Given the function that models the height of the object as;
h(t) = - 16t^2 + 80t + 96
The ball reaches the ground when h = 0
Substitute
0 = - 16t^2 + 80t + 96
Divide through by -16
0 = t²-5t-6
t²-5t-6 = 0
t²-2t-3t+6 = 0
t(t-2)-3(t-2) = 0
(tt-2)(t-3) = 0
t - 2 = 0 and t-3 = 0
t = 2 and 3s
Hence it will take the ball 2s or 3s to reach the ground
1) (green)
A = 1/2(4+8)(6)
A = 1/2(12)(6)
A = 36
2) (pink)
A = 1/2(8+16)(14)
A = 1/2(24)(14)
A = 168
Answer:
<u>Photo Lab:</u> 
<u>=3.20x +8</u>
<u>Specialty Photos:</u> <u>=2.60x + 10</u>
Step-by-step explanation:
At the Photo Lab, the cost is $3.20 per roll plus 8 per print.
Therefore, the cost of developing a roll of film is:
<u>=3.20x +8</u>
At Specialty Photos the cost is $2.60 per roll plus 10 per print.
Therefore, the cost of developing a roll of film is:
<u>=2.60x + 10</u>
