Answer:
t = 15.42 s
Step-by-step explanation:
A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation.
We ned to find the time when the rocket will the ground. For this, y = 0
It is a quadratic equation whose solution is given by :
Here, a = -16, b = 242 and c = 73
Neglecting negative value.
So, it will hit the ground in 15.42 s.
32.75 x .25
subtract the answer given with the original price, 32.75.
$24.56
Since the base is 3 inches and the height is 4 inches, as well as the area of a triangle being base*height/2, we get 3*4/2=6 in. for each triangle. Since we need 20 pieces for each puzzle, we multiply 6 by 20 to get 120. In addition, since 80 puzzles are needed, with 20 pieces for each puzzle, we have 120 inches for each puzzle and 120*80 = 9600 square inches of wood used
Answer: d, eight and fifty-three thousandths
Step-by-step explanation:
The number before the decimal place in the units column is a whole number (8).
The numbers after (.053) are thousandths because the whole number (8.053) consists of 4 numbers the same way a 1000 does.
Sorry I found the last bit harder to put into words, but I hope it helps :)
I am so so so sorry I do not know the answer but I might later in the shool year
