Answer:
7 seconds, 6 seconds
Step-by-step explanation:
a) For the object to reach the ground, the height from the ground has to be 0. therefore, let the function h = 0
0 = -16t^2 + 700
the amswers are + or - 6.61
we cant have negative time so it is approximately 7 seconds.
b) for the object to reach a 100 feet, h =100
100 = -16t^2 + 700
0 = -16t^2 + 600
solve: + or - 6.12
therefore it takes approximately 6 seconds to reach 100 feet.
parallel means same slope. m = 2
y - y₁ = m(x - x₁)
y - (-11)= 2(x - (-3))
y + 11 = 2(x + 3)
y + 11 = 2x + 6
<u> -11 </u> <u> -11 </u>
y = 2x - 5
Answer: A
The information is really hard to follow, you should ask the question with a screenshot of the data table.
Multiply everything in the parenthesis by a.
ac + ab = d
Subtract ab from both sides.
ac = d - ab
Divide a on both sides.
c = d - ab / a
Hope this helps!
