Answer:
Step-by-step explanation:
Given that,
Force, F = 50 pounds
It is directed at 30° from the horizontal.
The force will be given by :
So, the required force is 43.30 N.
80 x 70 = 5600 square feet total
5600 / 400 = 14
he would need 14 loads
Answer:
y =
Step-by-step explanation:
using the addition formula for sine
sin(x + y) = sinxcosy + cosxsiny
then
sinxcosy + cosxsiny = sinx + cosx
for the 2 sides to be equal , then
cosy = and siny =
then
y = ( ) =
and
y = ( ) =
thus y =
Answer:
x≤3 or x>10
Step-by-step explanation:
x≤3 because the dot is a solid dot at 3 and pointing backward toward numbers less than 3.
x>10 because the dot is an open circle pointing toward numbers greater than 10.
Using the quadratic formula we get
Therefore the tennis ball is at least 15 feet above the ground from 0.5 seconds to 2.04 seconds
