Answer:
The correct answer is 1/4(n - 64).
Step-by-step explanation:
1/4n - 16 Write Original expression
0.25n -16 Simplify the fraction
0.25(n - 64) Distribute(take out) 0.25 from n-16
1/4(n - 64)
Answer: Intercepting.
Step-by-step explanation:
1. To solve this problem and classify the system of equations shown above, you can graph it has you can see in the graph attached.
2. As you can see the lines intersect each other, this means that the system of equation has one solution and the lines are intersecting.
3. Therefore, the answer is the option A: Intersecting.
Answer:
The amplitude is 
Step-by-step explanation:
Let f(x) be a sinusoid function that has the following format:

Then b is the amplitude of the function
h is the vertical displacement of the wave
s is the phase angle
is the period.
In this problem 
Then 
Therefore the amplitude of the function is 
The amplitude is a measure of the vertical size of the sinx wave
The answers have square roots among the choices so we probably shouldn't use that calculator button.
We can't just apply the area of the trapezoid formula

where b is the bottom base, t the parallel top, and h the height, because we don't know the top t.
It will be 10 less the leg of that right triangle, which we calculate as

Now we can apply the trapezoid formula. We have


Choice b
