I think it’s a C since it doesn’t have a letter after since the others have the letters after Graph.
Answer: 
Step-by-step explanation:
By the negative exponent rule, you have that:
By the exponents properties, you know that:
Therefore, you can rewrite the left side of the equation has following:
Descompose 32 and 8 into its prime factors:
Rewrite:
Then:
As the base are equal, then:
Solve for x:
So i think what you do is if you make a number line like this:
1...2...3...4...5...6...7...8
you have to find out how many numbers are in between 4 and 7, so I would be 3 because there are 3 numbers I between 4-7.
so
a) 3
b) 6
c) 14
d) 8
Answer:
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
----> by angle addition postulate
substitute the given values
Answer: 42.9%
Step-by-step explanation:
Percent error is the difference between the measured and known value, which is divided by the known value, and then multiplied by 100%.
Percent error = (Estimated number- Actual number)/Actual Number × 100.
= (60 - 42)/42 × 100
= 18/42 × 100
= 0.429 × 100
= 42.9%
