Answer:
B) Multiply each side by 3
Step-by-step explanation:
This is how to solve for h
+ 7 = 5 (First Step --> Subtract 7 from both sides)
= - 2 (Second Step --> Multiply both sides by 3 to cancel out the denominator and to find just h)
h = -6
The fraction is : 71/100
The decimal is : 0.71
Answer:
The time it takes for the stone to reach the ground is 3.94 s. This answer is correct.
Step-by-step explanation:
I believe there's a mistake in the equation shown, the acceleration (number that multiplies t²) should be negative, since the stone is falling, therefore I'll answer assuming it's -16 instead of 16, otherwise there would be no real solution to the equation.
In order to calculate how long it'll take for the stone to hit the ground we must make f(t) = 0 and find the time "t" that makes the equation valid, so we have:
f(t) = -16t² + 248 = 0
-16t² = -248
t² = -248/(-16) = 15.5
t = sqrt(15.5) = 3.94
Answer:
Newton realized that the reason the planets orbit the Sun is related to why objects fall to Earth when we drop them. The Sun's gravity pulls on the planets, just as Earth's gravity pulls down anything that is not held up by some other force and keeps you and me on the ground.
