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: 10 years I think
Step-by-step explanation:
Answer:
Because the sum of these angles will always be 360°, then each exterior angle would be 60° (360° ÷ 6 = 60°). If each exterior angle is 60°, then each interior angle is 120° (180° − 60° = 120°).
Answer:
(0,2)
Step-by-step explanation:
The linear equation is mx+b=y.
m=slope
x= x coordinates
b=y intercept
y=y coordinates
In this case 2 is the y intercept.
Answer:
.5 is the remainder
Step-by-step explanation:
because the answer would be 56.5
