Answer:
The Answer is C.
Step-by-step explanation:
f(x) = cos x , g(x) = cos(x - π/4)
Equation: f(x) = a * cos (x - h) + k
Since the equation only has h = π/4, it means that it shift right.
Hello Ramirez,
I assume that you meant to put parenthesis around the entire expression for the denominator: (x^3 - 4x).
If so, then you would have a hole wherever the denominator is zero, because it would be undefined.
So let's factor: x^3 - 4x
First factor out an x to get x(x^2 - 4).
Then, we have the difference of squares, so we can factor it to: x(x+2)(x-2)
If we set that equal to zero, there are 3 possible solutions.
0, 2, and -2
These inputs would make the denominator zero and you would have a hole on your graph.
I hope this helps,

Answer:
constructing a 90% confidence interval
Step-by-step explanation:
quizlet
at a 95% confidence interval By use of the table we have a critical value of 1.96, and so the margin of error is 1.96/(2 √ 900 = 0.03267, or about 3.3%.

A 90% confidence interval has a z-score (a critical value) of 1.645. In conclusion, the margin of error is 2.52%.

Answer:
3589 feet
Step-by-step explanation:
The horizontal distance from the helicopter to the landmark is 3589 feet.
Answer: 11,304mi^2
We're finding area of a circle.
A = pi*r^2
A = pi*60^2
A = pi*3600
A = 11,304mi^2
