The equation can be used to model the height as a function is where t is time, the second option is correct.
<h3>What is trigonometry?</h3>
Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We know the general equation for the cosine function:
Where A is the amplitude
We have a wall clock that varies from 9 feet to 10 feet.
The value of 'A' is given by:
b is the cycle speed, we know:
(T is period)
The value of d is given by:
d = 9.5
The equation can be modeled:
(c =0 and y =h)
Thus, the equation is

Answer: B) 9
Step-by-step explanation:
You are not dumb. You just probably don't know how to solve this.
When you have the same base (3) raised to x exponent, and these bases are dividing each other, you put the same base and subtract exponents.
Another way of looking at this is;
Answer:
$1100. She would be paid $1100 monthly.
Step-by-step explanation:
Well first off. She gets paid WEEKLY at $275.
If she was paid MONTHLY we need to multiply $275 by the amount of weeks in a month.
Typically there are 4 weeks to a month so we would do 4 * $275.
4*$275=$1100
Answer:
g(f(4)) = -3
Step-by-step explanation:
f(x)=x-7
g(x) = x
g(f(4))
f(4) = 4-7
f(4) = -3
g(-3) = -3
Cos45 = cos(2*22.5) = (cos22.5)^2 - (sin22.5)^2 = (cos22.5)^2 * (1-(tan22.5)^2)
= (1 + cos45)/2 * (1-(tan22.5)^2)
Now, solve for tan22.5:
tan22.5 = sqrt(1 - 2cos45 / (1+cos45) )
