the volume of a cube depends on the length of its sides. The volume of a cube depends on the length of its sides. This can be written in function notation as v(s). What is the best interpretation of v(4) = 64?
Answer options in the picture.
Answers
Answer:
B. A cube with side lengths of 4ft has a volume of 64 cubic feet.
Step-by-step explanation:
The best interpretation of the function is that a cube with a side length of 4ft has a volume of 64ft³;
Function;
v(s) = s³
s is the side of the cube;
Now, if we input 4, the cube is 64
A function simply relates a set to another one.
So, answer choice B is the right one
Aaron travels 3 miles per hour in still water on his kayak. The expression 12 3 + x can be used to find the time it takes for him to travel with the current. If x represents the rate of the current, what does the denominator represent? A. the rate Aaron travels against the current B. the rate of the current C. the total distance Aaron kayaks D. the rate Aaron travels with the current
Answers
Answer:
A. The rate Aaron travels with the current
Step-by-step explanation:
Distance travelled = 3 mph in still water(downstream)
Time it takes for him to travel with the current = 12 / (3+x)
Where,
x = rate of the current
Denominator, 3 + x = The rate Aaron travels with the current
Therefore, the correct answer is
A. The rate Aaron travels with the current
5b - 5 - 126 - 7
I need steps please and thank you
Answers
Answer:
5b - 138
Step-by-step explanation:
Alright let's break it down.
First, you can see that each constant (5,126,7) have negatives in front of them. SO you are going to subtract each one of them.
When subtracting negatives it's basically just adding them together. How to do it is simply adding:
5 + 126 + 7
Then you get 138.
BUT, it was negative numbers. So it's actually -138.
Then bring back the 5b and your answer is:
5b - 138
