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.
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
What polynomial has quotient
x^2 + 6x − 2 when divided by x + 3?
Answer:
[tex]x^3+9x^2+16x-6[/tex]
Step-by-step explanation:
When you learned to divide numbers, you said that 10 divided by 2 has quotient 5 since 5 times 2 was 10.
Same difference, let's multiply the two polynomials:
[tex](x^2+6x-2)(x+3) = x^3+9x^2+16x-6[/tex].
that assuming that you want no remainder. If you care about the remainder, just change the constant term with anything you want. the distance from [tex]-6[/tex] will be your remainder.

Given that x = 7.3 m and θ = 40°, work out AB rounded to 3 SF.
Answer:
AB ≈ 4.69
Step-by-step explanation:
using the sine ratio in the right triangle
sinΘ = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AB}{AC}[/tex] = [tex]\frac{AB}{x}[/tex] , then
sin40° = [tex]\frac{AB}{7.3}[/tex] ( multiply both sides by 7.3 )
7.3 × sin40° = AB , then
AB ≈ 4.69 ( to 3 sf )

Matthew is given a $25 music gift card for his birthday. He downloads one song and the value of the card is $23.50. After two downloads, its value is $22. Write a formula to represent the remaining value on the card as an arithmetic sequence. What is the value of the card after 10 downloads? The value of the card after 10 downloads is
The formula to represent the remaining value of the card is aₙ = 26.5 - 1.5n
The value of the card after ten downloads is $10
Arithmetic formulaaₙ = a + (n - 1)d
where
a = first term
d = common difference
n = number of terms
Therefore,
a = 25
d = 23.5 - 25 = - 1.5
Therefore,
aₙ = 25 + (n - 1)(-1.5)
aₙ = 25 - 1.5n + 1.5
aₙ = 26.5 - 1.5n
After ten download the value of the card will be as follows,
26.5 - 1.5(11) = 26.5 - 16.5 = $10

Find the measurement of the missing angles.
Answer:
Answers to 1 and 5:
Q1 Angle 1: 129 degrees
Q1 Angle 2:116 degrees
Q5 Angle 1: 143 degrees
Q5 Angle 1: 78 degrees
Step-by-step explanation:
I cannot solve all of these, however I can still solve some of them. We know that one side of a straight line is 180 degrees.
Question 1:
If the angle that is next to angle 1 is 51 degrees, then we simply do: 180-51. The result will be 129 degrees.
The angle next to angle 2 is 64. 180-64= 116 degrees.
Question 5:
The angle next to angle 1 is 37. 180-37= 143 degrees.
The angle next to angle 2 is 102. 180-102=78 degrees.
Note: I am really sorry that I wasn't able to answer all the questions. If I got any of these answers wrong, please write it in the comments and I will try to edit my answer.

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
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
