Step-by-step explanation:
f(x)=8(5x-2)
interchanging the role of x&y
x=8(5y-2)
- x=40y-16
- x+16=401y
- y=(x+16)/40
f-1(x)=(x+16)/10

Answer: The correct answer is the last choice.
In the first segment of the trip, the car goes from 0 to 2 hours and the line is moving up. Therefore, it traveled for 2 hours.
In the second segment, the line went straight horizontal for 1 hour. That means the distance didn't change, in other words it didn't move.
In the last segment, it moved up again for 2 hours.
No
Step-by-step explanation:
they could be but it doesnt say where the angle is so there isn't enough information to tell if they are congruent. answer is no

Step-by-step explanation:
Sin 21 = 
Sin 21 = 
0.3583 = 
0.3583*15 = BC
BC = 5.3745 = 5.37 m
Tan ∅ = 
Tan ∅ = 
∅ = tan⁻¹ (0.7448) = 36.67 = 36.7
Answer:

Step-by-step explanation:
For any angle
, we have that:

Quadrant:
means that
is in the first quadrant. This means that both the sine and the cosine have positive values.
Find the cosine:







Since the angle is in the first quadrant, the cosine is positive.
