d because you take the denominator of the fraction and you put it infront of the square root then you take the numerator and multiply it by the number at hand in this case 7
Answer:
h(t) = -16t2 + 144
h(1) = -16(12) + 144 = 128 ft
h(2) = -16(22) + 144 = 80 ft
h(2) - h(1) = 80 - 128 = -48 ft
It fell 48 ft between t = 1 and t = 2 seconds.
It reaches the ground when h(t) = 0
0 = -16t2 + 144
t = √(144/16) s = 3s
It reaches the ground 3s after being dropped.

Answer:
11.1
Step-by-step explanation:
0.5(−77.8−11)/−4
=(0.5)(−88.8)/−4
=−44.4/−4
=11.1
Answer:
DF^2=DH^2+HF^2
DF=√DH^2+HF^2
DF=√2(DH^2) {AS IT IS A CUBE THEN ALL SIDES ARE EQUAL}
DF=√2*11^2 {ALL SIDES OF A CUBE ARE EQUAL}
DF=√2*121
DF=√242
DF=15.555
THEREFORE,OPTION B..
-(12x - 6) = 12x + 6
First, distribute the negative sign on the left side.
It is the same as multiplying the quantity in parentheses by -1.
-1(12x - 6) = 12x + 6
-12x + 6 = 12x + 6
Now, subtract 12x from both sides.
-24x + 6 = 6
Subtract 6 from both sides.
-24x = 0
Divide both sides by -24.
x = 0/(-24)
x = 0
Answer: x = 0
