#1) 4.445 ft
#2) yes
Explanation
#1) The maximum height is the y-coordinate of the vertex. We first find the axis of symmetry, given by x=-b/2a:
x=-0.17/2(-0.005) = -0.17/-0.01 = 17
Plugging this into the equation,
y=-0.005(17²)+0.17(17)+3 = 4.445
#2) Substituting 30 into the equation,
y=-0.005(30²) + 0.17(30) + 3 = 3.6
The ball will 3.6 in the air, so yes, it will clear the 3 ft tall net.
Step-by-step explanation:
Co interior angles' sum is 180°
A minus x plus b equals c
Add 5 to both sides to get x alone and you will have your answer which is x= -3
Answer:

Step-by-step explanation:
As we are given the adjacent (a) side and the hypotenuse (h), we can use the cosine function to find the measure of angle B.
Recall that 
This means that in order to find B, we need to take the inverse of cosine
This gives us

From a calculator, we find that the answer of this is

When this is rounded to the nearest hundredth, we get
