Do you recognize that the hypotenuse here has the length 22 and that the opposite side is the unknown (x)? The angle is 21 degrees.
This is a perfect application of the tangent function:
tan 21 deg = opp / adj = opp / 22 = x / 22
tan 21 deg = 0.384 so x would be 22 tan 21 deg, or
x = 22*(0.384)
= 8.45 (answer)
Answer:
The slope of problem 11 is

The slope of problem 10 is

Their sum can be both equal, or greater. If you have 3/8 and 6/8, you would get 9/8 or 1 and 1/8. Which is greater than 1. Also if you add 2/6 and 4/6, you get 6/6 or 1. proving that both are possible.
Answer:
4104.79 Seconds or about 1.14 Hours
Step-by-step explanation:
26mi = 41842.9m
100/9.81 = 41842.9/x
41842.9 x 9.81 = 100x
410478.849 = 100x
x = 4104.78849
Answer:
1a: f(-2) means substituting -2 for x
1b: 65
I don't know the second one
