SOLUTION:
120 miles = 60 seconds
120 ÷ 240 = 60 ÷ 240
120 × 1 / 240 = 60 × 1 / 240
120 / 240 miles = 60 / 240 seconds
1 / 2 mile = 1 / 4 seconds
1 / 2 mile = 1 / 4 ÷ 60
1 / 2 mile = 1 / 4 × 1 / 60
1 / 2 mile = 1 / 240 minute
FINAL ANSWER:
Therefore, it will take Rachel 1 / 240 of a minute to swim a 1 / 2 mile.
Hope this helps! :)
Have a lovely day! <3
Answer:
A
Step-by-step explanation:
Here, we want to get the number that will be in the units place
Six consecutive numbers from 33 are;
33 , 34 , 35 , 36 , 37 , 38 ,
Product of 5 and any of the even numbers will yield 0
That means the number on the unit place is 0
I think you have to solve this with number and line
When taking square roots, you can't take square roots of negative roots of negative numbers. So, what will work for the domain of u(x) is what makes u(x) zero or more. We can make an inequality for that.
u(x) ≥ 0.

9x + 27 ≥ 0 by squaring both sides
9x ≥ -27
x ≥ -3
So the domain of the function is when x ≥ -3 is true.
