Answer: Choice B
======================================================
Explanation:
The original equation is 
with 8 as the base. That is also the base of the log when we get the final answer shown above. Logs are useful to isolate the exponent.
The general rule is that 
is equivalent to the log form of 
where b is the base of each.

Answer:
12.0 cm
Step-by-step explanation:
The Pythagorean theorem applies:
(12 cm)² +b² = (17 cm)²
b² = (289 -144) cm² = 145 cm²
b = √145 cm ≈ 12.04 cm
b ≈ 12.0 cm . . . . rounded to 1 decimal place
Answer: The answer is A. 3/5
Step-by-step explanation:
Cos is the X coordinate given in parenthesis.
The X coordinate is 0.6, so find the fraction which equals 0.6.
3/5 = 0.6
57% rounded. Pretty sure that's it

y =-22x+32
Step-by-step explanation:
Given that the functions f and g are differentiable for all real numbers x. The table below gives values for the functions and their first derivatives at selected values of x.
x f(x) f'(x) g(x) g'(x)
1 4 -3 5 2
2 -3 -1 4 6
3 π 8 -1 4
4 -5 unknown 0 3
a) 
(using quotient rule)
Substitute 1 for x
b) 
when
