12
Step-by-step explanation:
Use pythag to solve.
x^2+5^2=13^2
x=12
Answer:
divide the 70.00 by the four hours
Step-by-step explanation:
Answer:
The frequency of the given sinusoidal graph is 4.
Step-by-step explanation:
The frequency of a sinusoidal graph is the number of cycles it completes in the interval 0 to 2π radians.
From the given sinusoidal graph it is noticed that the the graph complete its one cycle in the interval 0 to
.
If the complete its one cycle in
, then the number of cycles completed by the graph in the inteval 0 to 2π is



Therefore the frequency of the given sinusoidal graph is 4.
The given equation is

x intercept
To find the x intercept, we have to plug 0 for y and solve for x.That is

So x intercept is (6,0) .
y intercept
To find the y intercept , we have to plug 0 for x and solve for y. That is

So the y intercept is (0,-9) .
The answer I'm pretty sure is B but I can't really explain it, sorry
