Answer:
100
Step-by-step explanation:
10000 divided by 100 is 100
you know that sin 90 is 1 and cos 45 is 1/√2
so,
set it up like a y= equation.
which would be y=-x^2+7
to find the vertex, you substitute the 0s.
so 0=-(0)^2+7
-0^2=0
0+7=7
0=7
(0,7)
3
3(m+8)
first you add m to 8, so you would do m+8. then you triple that, means multiply it by 3. so 3(m+8)
12.8 feet
