Answer:
Step-by-step explanation:
It wo be B= -8
When the penny hits the ground, h will = 0.
So: Set h(t) = 0 = -4.9t^2 + 0t + 150 m
Then 4.9t^2 = 150, and so t^2 = sqrt(150 / 4.9) = plus or minus 5.53 sec.
We can use only the positive root, as we're measuring time.
t = 5.5 sec (answer)
Answer:
The answer is A. Angles are proportional, side lengths are larger.
Step-by-step explanation:
That’s because scale factors greater than one make a shape larger, and the angles are proportional it's the lengths of the size that change.
If you are looking for volume you want v by itself so your formula would look like this : d*m=v
