Answer:
A
Step-by-step explanation:
If you graph the equation f(x) = -16x^2+25x+15. You would need to pay attention to the x value which is somewhere in between 0.75-0.9.
Another way is to convert the equation into vertex form.
The 1st one
Well it's the same as normal exponents so you multiply 2/3 x 2/3 x 2/3 x 2/3 x 2/3
A square has two parallel sides and four right angles.
it's plural so axes*
and in pilar coordinates, the axes are circular so they never intersect but the centre point is still called origin.
Answer: 
Step-by-step explanation:
Given
Two forces of 9 and 13 lbs acts
angle to each other
The resultant of the two forces is given by

Insert the values

Resultant makes an angle of

So, the resultant makes an angle of
with 9 lb force
Angle made with 13 lb force is
