11. how does the value of k affect the graph?
12. how does the value of h affect the graph?
13. how do the sign and absolute value of A affect the graph?

Answers

Step-by-step explanation:

Given the general form of the absolute value function, y = a|x - h| + k

11. How does the value of k affect the graph?

The value of k determines how far up or down the parent function is translated. If k is positive, the function is translated k units up. If k is negative, the function is translated |k | units down.

12. How does the value of h affect the graph?

The value of h determines how far left or right the parent function is translated. If h is positive, the function is translated h units to the right. If h is negative, the function is translated |h | units to the left.

13. How do the sign and absolute value of A affect the graph?

The value of a determines whether the graph opens up or down.

If a is positive, the graph opens up.If a is negative, the graph opens down.

The value of a also makes the parent function wider or narrower.

If 0 < a < 1, the graph is wider than the parent function.If a > 1, the graph is narrower than the parent function.

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.

Answers

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.

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

Answers

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.
