The correct answer is b. The domain of the function is in terms of x, so we are looking at the x-axis. The line stretches from 3 to 7 on the x-axis, so we know that b is our answer.
The answer is 7^4 / 3^10.
$76.5
51/6 = 8.5
8.5 x 9 = 76.5
Do you know your trig ratios?
A x b = 24
Possible values of a and b are:
1 x 24 = 24
2 x 12 = 24
3 x 8 =24
4 x 6 = 24
The possible sums of a and b are:
1 + 24 = 25
2 + 12 = 14
3 + 8 = 11
4 + 6 = 10
Therefore, the least possible sum of a and b is 10.
