Answer:
<h2>12</h2><h2 />
Step-by-step explanation:
<u>3</u> =<u> x </u>
8 32
8 (x) = 32 (3)
x = <u>32 (3)</u>
8
x = 12
You would have to put 21.3 on top and 1.9 under it. then you would have to borrow the number. the answer would be 19.4
H = 5 + ut - 16t^2
When the balls falls back to the ground, h = 0
0 = 5 + 3.2u - 16(3.2)^2
0 = 5 + 3.2u - 163.84
0 = 3.2u - 158.84
3.2u = 158.84
u = 158.84/3.2 = 49.6 ft/s
Required equation is
h = 5 + 49.6t - 16t^2
You just substitute the value of x in the given equation:
f(x) = 2x^2 - 5
f(-4) = 2 (-4)^2 -5 = 27
f(x) : a name given to the equation
f(-4): refer to the equation when the value of the independent variable x has the value between the brackets.
