Answer:

25

Step-by-step explanation:

It's what the others said, i'll change it if it's wrong

Based on the description of cost and the equation used, m in the equation would represent $25

m in the equation, y = mx + b, is the gradient. It is the figure that shows how much the cost will change in relation to time or activity.

In other words, m is the variable cost.

The only variable cost above is $25 which is variable because it increases per hour worked. m is there $25.

In conclusion, m is $25.

The difference quotient for f(x) = 3x2 – 12 is 6x + 3h

The function is given as:

f(x) = 3x^2 – 12.

Calculate f(x + h)

f(x + h) = 3(x + h)^2 – 12

The difference quotient is then calculated using:

[tex]f'(x) = \frac{f(x + h) - f(x)}{h}[/tex]

This gives

[tex]f'(x) = \frac{3(x + h)^2 - 12 - 3x^2 + 12}{h}[/tex]

Evaluate the difference

[tex]f'(x) = \frac{3(x + h)^2- 3x^2}{h}[/tex]

Expand

[tex]f'(x) = \frac{3x^2 + 6xh + 3h^2- 3x^2}{h}[/tex]

Evaluate the difference

[tex]f'(x) = \frac{6xh + 3h^2}{h}[/tex]

Evaluate the quotient

f'(x) = 6x + 3h

Hence, the difference quotient for f(x) = 3x2 – 12 is 6x + 3h

Answer:

It will take 5 months for the two fitness clubs to have the same number of members

Step-by-step explanation:

Let the number of months it takes fitness club A  and B to have the same number be = x

For the two clubs to have the same number in x months, that means we can set up an equation as follows

450 +15x = 400 + 25x

Grouping like terms

450 - 400 = 25x -15x

50 = 10x

x= 5

Therefore, it will take 5 months for the two fitness clubs to have the same number of members

Answer:

f(x)=(x-1)(x+1)^2(x-4)^3

Step-by-step explanation:

The zeros of the function are x=-1, x=1, and x=4, so its factors are x+1, x-1, and x-4.

The graph touches, but doesn’t cross, the x-axis at x=-1. So the factor x+1 is a repeated factor with an even multiplicity.

The graph crosses the x-axis at x=4, but with a little curve before and after it meets this point. So the factor x+4 is a repeated factor with odd multiplicity.

The graph crosses the x-axis at x=1 with no curve before or after. So the factor x-1 is not a repeated factor.

Therefore, function f is defined by f(x)=(x-1)(x+1)^2(x-4)^3.

The sixth-degree polynomial that shows in the graph is [tex]\rm f(x) = (x+1)(x-1)^2(x-4)^3[/tex] and this can be determined by evaluating the x-intercept of the given graph.

Given :

Sixth-degree polynomial -- [tex]\rm f(x) = (x-b)(x-c)^2(x-d)^3[/tex]

The following steps can be used in order to determine the value of b, c, and d:

Step 1 - Write the given sixth-degree polynomial.

[tex]\rm f(x) = (x-b)(x-c)^2(x-d)^3[/tex]

Step 2 - Observe the given graph and determine the x-intercept of the graph of the sixth-degree polynomial.

Step 3 - So, the x-intercepts that are the values of b, c, and d is given below:

b = -1

c = 1

d = 4

Step 4 - Substitute the values in the given sixth-degree polynomial.

[tex]\rm f(x) = (x+1)(x-1)^2(x-4)^3[/tex]

Answer:

x=-6

Step-by-step explanation:

use distributive property on the () and times x and 1 by three

then you subtract 6 from both sides

then subtract three from both sides

then divide both sides by 3

your work would look like this:

3(x+1)+6=-9

3x+3+6=-9

3x+3=-15

3x=-18

x=-6

Hope this helps!

Answer:

X=6

Step-by-step explanation:

3(x+1)+6=−9

Step 1: Simplify both sides of the equation.

3(x+1)+69(3)(x)+(3)(1)+6=−9

(Distribute)

3x+3+6=−9(3x)+(3+6)=−9

(Combine Like Terms)

3x+9=−93x+9=−9

Step 2: Subtract 9 from both sides.

3x+9−9=−9−93x=−18

Step 3: Divide both sides by 3.

3x3=−18/3

Answer:

Domain: [-2, 0, 2, 4]

Range: [3]

Step-by-step explanation:

The domain of the function are all values of x that are plotted on the horizontal axis (x-axis), while the range are the corresponding y-values plotted on the vertical axis (y-axis).

Therefore,

Domain of the function = [-2, 0, 2, 4]

Range of the function = [3] (only 1 possible value of y can be seen as plotted on the gray]

Answer:

a. x = -4

c. x = 9

Step-by-step explanation:

Values of g(x), output values, are plotted on the y-axis, while the corresponding x values, input, of the function are plotted on the x-axis.

We are to determine all possible input values (x-values) that will give us an output value, g(x) = 8.

On the graph, look at the point where y = 8, on the y-axis. When y = 8, we have two possible values of x. They are -4, and 9.

Thus:

g(-4) = 8

g(9) = 8.

The possible input values for which g(x) = 8, are x = -4, and x = 9.

Answer:

The height, h, of the rock as a function of the horizontal distance from Jeremy's hand is h = -13/784·(x - 28)² + 17

Step-by-step explanation:

The given parameters are;

The height of the rock above the water when it leaves Jeremy's hand = feet

The maximum height of the rock = 28 feet

The horizontal distance at maximum height = 17 feet

Therefore, the given coordinates of the maximum height = (28, 17)

The equation of a parabola in vertex form is f(x) = a(x - h)² + k

Taking the maximum point as the vertex of the parabola, we have;

(h, k) = (28, 17)

Substituting the values gives;

f(x) = a·(x - 28)² + 17

At x = 0, the height = 4, we have;

f(0) = 4 = a·(0 - 28)² + 17

4 - 17 = a×28²

-13 = 784 × a

a = -13/784

Therefore, the height of the rock, f(x) = h, as a function of the horizontal distance from Jeremy's hand is therefore;

f(x) = h = -13/784·(x - 28)² + 17
