Parallel lines have the same gradient
rearrange the equation so they will be in the form y = mx + c, where m is the gradient
y = -6x - 8
y = 2x + 5
as you can see, since they do not have the same gradient, they are not parallel lines
Answer:
- a) 6.5 seconds
- b) 13 seconds
- c) 679 ft
Step-by-step explanation:
<u>Given function:</u>
a) <u>Maximum height is the vertex.</u> The ball reaches the maximum after:
- h = -208/2(-16) = 6.5 seconds
b) <u>Time the ball was in the air:</u>
Solving we get approximately t = 13 seconds
c) <u>Maximum height is at vertex, we found t above:</u>
- h(6.5) = -16(6.5)^2 + 208*6.5 + 3 = 679 ft
27 , he cut 27, pkease give me a brainliest!!
I'm pretty sure the answers are G and B
