Answer:
f(1) = -3
f(8) =3
f^-1 (5) =2
f^-1 (2) =4
Step-by-step explanation:
f(1) = is the value when x=1 which is -3
f(8) = is the value when x=8 which is 3
f^-1(5) is x value when y=5 so find y=5 in the table and read the x value x=2
f^-1 (2) is the x value when y=2 so find y=2 in the table and read the x value x=4
Answer: 
Step-by-step explanation:
For this exercise it is important to remember that:
1. The word "difference" indicates subtraction (The result of a subtraction is called "difference").
2. The multiplication of signs:

For this case, according to the data given in the exercise, the records high temperature and the record low temperature are:

Therefore, if you want to find the difference in the record temperatures, you need to sutract them.
Then you get the following result:
9514 1404 393
Answer:
(a, B, C) ≈ (9.15, 29.2°, 102.8°)
Step-by-step explanation:
The given angle lies between the given sides, so the law of sines cannot be used. The third side is ...
a² = b² +c² -2bc·cos(A) ≈ 83.6452
a ≈ √83.6452 ≈ 9.146
__
Then angle B is found from the law of sines. We want to find the smaller angle, so we can tell if the triangle is acute or obtuse.
sin(B)/b = sin(A)/a
B = arcsin(b/a·sin(A)) ≈ arcsin(0.48753)
B ≈ 29.2°
C = 180° -48° -29.2° = 102.8°
The solution to the triangle is (a, B, C) = (9.1, 29.2°, 102.8°).
Your answer is 8 is exponent
