The answer is true. We know this because 9^2 - 6^2 is 45.
A and b are perpendicular meaning that they intersect forming 90
b and c are parallel meaning that the intersection of c and a is also perpendicular
11x - 9 = 90 degrees
solve
11x - 9 = 90
add 9 to both sides
11x = 99
divide both sides by 11
x = 9
Hope this helps
Answer:
Rewrite the equation as x+xyz=wx+xyz=w.
x+xyz=wx+xyz=w
Subtract xx from both sides of the equation.
xyz=w−xxyz=w-x
Divide each term by xzxz and simplif
Answer:
- h(t) = -16t^2 +188
- 3.4 seconds
Step-by-step explanation:
The usual equation for ballistic motion is ...
h(t) = -16t^2 +v0·t +s0
where v0 is the initial upward velocity, and s0 is the initial height above some reference point.
Here, we presume there is no initial vertical velocity, and the height is given as 188 ft above the river. Since we want the time to reach the river, we're solving ...
h(t) = -16t^2 +188
h(t) = 0
-16t^2 +188 = 0
t^2 -11.75 = 0
t = √11.75 ≈ 3.4
It takes about 3.4 seconds for the log to reach the river.
