Answer:
22
Step-by-step explanation:
10% of 20 is 2, so when you add the previous amount and the percentage you end up with 22
12 miles in 48 minutes
12/48 or 1/4 miles per minute
Times 60 is 15 miles per hour
Answer:
3+x sqrt 7 -13 is a radical equation.
Answer:
D.
Step-by-step explanation:
To tell whether the domains can include 0, all you need to do is find where x = 0, and whether the y-value is real.
h(x) = sqrt(2x^2 + 5x - 3)
= sqrt(0^2 + 5 * 0 - 3)
= sqrt(-3)
Since this includes the square root of a negative number, h(0) is an imaginary number. That means that we can eliminate choices A and B.
If you look at the graph of w(x), when x = 0, there is a real value for the y-value on the graph. But, if you think about it, if you have 0 workers, there is no way that you can still be producing wrenches. So, the domain cannot contain 0.
Your answer will be D.
Hope this helps!!
