Answer:
Step-by-step explanation:
A local maximum or local minimum is the point where the tangent drawn to it is parallel to the x axis.
The crest of a wave is local maximum and the trough of wave is local minimum.
Here, in the graph, there are 2 troughs and 1 crest.
The crest is at . So, the local maximum is at .
The interval of the local maximum is between and .
So, the option that matches with the above interval is .
Answer:
3 option Is the correct answer right
A. 30 miles
step by step explanation: 14.75-4.25 (one time fee)
14.75-4.25=10.5
10.5 divided by 0.35 is 30
therefore the answer is A, 30 miles
Answer:
16
Step-by-step explanation:
Given x^2 + 16x = 18. Complete the square:
Take half of the coefficient of x (in other words, take half of 16) and square the result: we get 8^2 = 64.
Add 64, and then subtract 64 from x^2 + 16x + 64 = 18 + 64
Then (x + 8)^2 = 82. From this point on it's easy to find the roots, but we were not asked to do so.
The desired number is 64; note that it is (16/2)^2.
