Answer:
Solution is 34
Step-by-step explanation:
to find f(8) you plug in 8 for x in the equation
f(x)=4(8)+2=34
hope this helps.

Answer: quadrant 3</h3>
Work Shown:
Divide 1300 over 360
1300/360 = 3.611 approximately
Focus on the whole part 3. There are 3 full revolutions
3*360 = 1080, which subtracts off to get 1300-1080 = 220 left over.
The remainder 220 tells us where the angle points. It's in quadrant 3 since 220 degrees is between 180 degrees and 270 degrees.

Answer: 1/70
Step-by-step explanation:
This is a question that can also be interpreted as what is the probability of having the first number of a phone number to be 8 and the last number of the phone number to also be 8. This answer gives the fraction of the phone numbers that starts with 8 and end with 8.
Since three numbers (0,1,2) cannot start a phone number and we are left to pick from 7 numbers,
then the probability of figure "8" starting phone number = 1/7
Since all 10 numbers can possibly end a phone number,
then the probability of having figure "8" as the last digit of a phone number = 1/10
Hence probability of having "8" as the first and last digit of a phone number = fraction of total telephone numbers that begin with digit 8 and end with digit 8 = 1/7 × 1/10 = 1/70.
