The cinematic equation is:
h (t) = (1/2) * a * t ^ 2 + vo * t + h0
Where,
a: acceleration
vo: initial speed
h0: initial height
Substituting values:
h (t) = (1/2) * (- 32) * t ^ 2 + (0) * t + 9
h (t) = - 16t ^ 2 + 9
For t = 0.2 we have:
h (0.2) = - 16 * (0.2) ^ 2 + 9
h (0.2) = 8.36 feet
To touch the ground we have:
-16t ^ 2 + 9 = 0
16t ^ 2 = 9
t = root (9/16)
t = 0.75 s
Answer:
The height of the cherry after 0.2 seconds is:
h (0.2) = 8.36 feet
the cherry hits the ground at:
t = 0.75 s
1080 dollars. The first interest is 2700 and the second is 1620.
i think you do it by like
12squared - 1.5 squared = A Squared
you do this to get the height
so
144- 2.25 = 141.75 then you square root it which equals 11.90
11.90×3÷2 = 17.85
17.85×6= 107. 15
im not sure
Answer:
n = 5/2
Step-by-step explanation:
(2n + 4) + 6 = -9 + 4(2n + 1)
2n + 4 + 6 = -9 + 8n + 4
2n + 10 = 8n - 5
15 = 6n
n = 5/2
Hope this helps!
Pizza = x
Sandwiches = 2(x-4)
So if sandwiches = 62
62= 2(x-4), multiply 2 into the para-thesis
62 = 2x - 8 (add 8 to both sides)
70 = 2x (divide both sides by 2)
x = 35 I hope this helps
