Answer:
Step 1: Simplify both sides of the equation.
Step-by-step explanation:
x+−13=13
The answer to 6 is point Q
Answer:
12
Step-by-step explanation:
14 doesn't go into both 48 and 84. 12 is the next highest and it goes into both of them.
a. Factorize the denominator:
Then we're looking for such that
If , then ; if , then . So we have
as required.
b. Same setup as in (a):
We want to find such that
Quick aside: for the second term, since the denominator has degree 2, we should be looking for another constant such that the numerator of the second term is . We always want the polynomial in the numerator to have degree 1 less than the degree of the denominator. But we would end up determining anyway.
If , then ; if , then . Expanding everything on the right then gives
which tells us and ; in both cases, we get . Then
as required.
Answer: 22 feet.
Step-by-step explanation:
Note that there are two right triangles in the figure attached: ACD and BCD. Where "h" is the height of the chimeney from John's eye level to the top of the chimney.
You need to use the trigonometric identity for this exercise.
Solve for h:
Substitute and solve for h:
