Answer:
A familiar use of modular arithmetic is in the 12-hour clock, in which the day is divided into two 12-hour periods. If the time is 7:00 now, then 8 hours later it will be 3:00. Simple addition would result in 7 + 8 = 15, but clocks "wrap around" every 12 hours.

A cube has an edge of 3 feet. The edge is increasing at the rate of 4 feet per minute. Express the volume
of the cube as a function of m, the number of minutes elapsed.
Hint: Remember that the volume of a cube is the cube (third power) of the length of a side.
Answer:
so it increases by 4 per minute
the volume of a cube is v=side^3
so the side length be 5+4m where m is the number of minutes
therefor the volume can be expressed as V(m)=(5+4m)³
Step-by-step explanation:
The volume of the cube can be expressed as a function of m, the number of minutes elapsed as V(m) = (3 + 4m)³ feet³.
What do we mean by volume?The volume of an object is the total space occupied by the object in the three-dimensional space.
How do we solve the given question?In the question, we are asked to express the volume of a cube as a function of m, the number of minutes elapsed. We are given that the initial length of the edge of the cube was 3 feet, and it increases at a rate of 4 feet per minute.
∴ We can say that the length of the edge after m minutes = 3 + 4m
As 4 feet is the increase per minute and m minutes have elapsed.
We know, that the volume of a cube is the cube of the length of the edge.
∴ The volume = (3 + 4m)³.
Hence, the function of the volume of the cube in m can be written as,
V(m) = (3 + 4m)³ feet³.

-Giving a brainely for correct answer
Answer:
Below.
Step-by-step explanation:
They are of the form y = kx where k is some constant.
8x + 2y = 0 is Direct Variation because you can transform it:
8x + 2y = 0
2y = -8x
y = -4x :- here k = -4.

 Line v passes through point (6, 6) and is perpendicular to the graph of y = 3/4x - 11. Line w is parallel to line v and passes through point (–6, 10). Which is the equation of line w in slope-intercept form?
A: y= 3/4x+2
B: y=-3/4x+2
C: y=-4/3x+2
Answer:
Step-by-step explanation:
Perpendicular lines have negative reciprocal slopes.
Parallel lines have identical slopes
As our original line has a slope of 3/4, both lines v and w have slope of -4/3
This means that
C: y = -4/3x + 2
is the only possible option.
Let's check that the given point fits on this line.
10 = -4/3(-6) + 2
10 = 10
So our answer is correct.
