Answer:
11/7 feet
Step-by-step explanation:
the perimeter of a circle is πr²
and a semi circle is half of a circle then the formula would be 1/2 πr²
1/2×22/7×1 (it is 1 because we have divided the diameter to get radius
so we derived at 11/7
Step 1: Find the slope
(y-y)/(x-x) = (8-8)/(9+4) = 0
Step 2: Substitute into the slope intercept equation
y - y = m(x - x)
y - 8 = 0(x - 9)
If the problem just wants plain, slope intercept form, then this is your answer.
If not, y = 8
Ok
y=-0.04x^2+8.3x+4.3
when the rocket reaches the ground (when height=0, ie when y=0), then the rocket will land, find the x coordinate
set y=0
0=-0.04x^2+8.3x+4.3
use quadratic formula
if you have ax^2+bx+c=0, then
x=

a=-0.04
b=8.3
c=4.3
x=

x=208.017 or -0.516785
xrepresents horizontal distance
you cannot have a negative horizontal distance unless you fired and theh wind blew it backwards
therefor x=280.017 is the answer
208.02 m
$7.35. All you do is multiply the two together
Answer: I’m not really sure what the correct answer is if you could help that would be great so let me know
