(f∘g)(2) = f(f(2)) = f(4(2)-7) = f(1) = 4(1)-7 = -3
2.4 +2/5 = 2.8
2.8 / 1/5= 70 / 5 = 14 / 1
The multiples of 3 are 3, 6, and 9. There are 10 spots.
10/10 - 3/10 = 7/10
The answer is 7/10, 0.7, or 70%.
Using the slope concept, it is found that the change in elevation was of -699 feet.
<h3>What is a slope?</h3>
The slope is given by the <u>vertical change divided by the horizontal change</u>, and it's also the tangent of the angle of depression.
In this problem, we have that:
- The vertical change is of h.
- The horizontal change is of 10,000 feet.
Hence:
tan(-4º) = h/10000
h = 10000 x tan(-4º)
h = -699.

Shorter piece = x
Longer piece = 2x
x + 2x = 33
3x = 33
x = 11 feet
2x = 11 × 2
2x = 22 feet
So one piece will be 11 feet and the other will be 22 feet.
Hope this helps!
