F(x) can be written as:
f(x) = Asin(2x); where A is the amplitude and the period of the function is half that of a normal sin function.
f(π/4) = 4
4 = Asin(2(π/4))
4 = Asin(π/2)
A = 4
Amplitude of g(x) = 1/2 * amplitude of f(x)
A for g(x) = 2
g(x) = 2sin(x)
Answer:
the third one ( -7+u+8t)
Step-by-step explanation:
first you add the ts together and you get 8. Then u keep the U and cancel out the +2 nad the -2. Then you are left with your answer. have a nice day
Answer:
7
Step-by-step explanation:
3^2 = 9
(-4)^2 = 16
16-9= 7
The answer is the last option: 
Explanation:
1. You have that the equation of the line is:

Where
is the slope of the line and
is the intercept with the y-axis.
2. Therefore, you must find
.
3. Then, you must substitute the points given in the problem and the slope into the equation of the line and solve for
, as following:
