The equation of the perpendicular line is y = x + 3

Perpendicular line:

The perpendicular line means a straight line that makes the right angle (90 degrees) with the other line.

Given,

Here we have the equation y = -x + 3.

Now, we need to find the equation of the perpendicular line.

In order to find the equation of a perpendicular line, first we need to find the negative reciprocal of the slope given.

Through the given equation we have identified the slope of the line is -1. so the slope of the perpendicular line will be 1.

While looking at the graph we have identified the y intercept of the equation is 3.

So now we know the values of y-intercept and slope.

We just put them together, and apply it one the standard form of the equation of line, then we get,

y = 1x + 3

y = x + 3.

Therefore, the equation of perpendicular line is y = x +3.

The marginal profit is -41 dollars.

In accounting, a profit is an income that is given to the owner throughout a successful market producing process (business).

The advertising is given by P(x) = 930 + 15x -4x².

The marginal profit at x = 7 is given by

P(x) = 930 + 15x -4x²

P'(x) = 15 - 8x

Now at x = 7 the marginal profit is

P'(7) = 15 - ( 8×7 )

or, P'(7) = -41

Hence there will be marginal profit of -41 dollars.

Answer:

  [tex]y=\begin{cases}-\dfrac{7}{2}x-16&\text{for $-6\le x\le-4$}\\\\\dfrac{1}{5}x-\dfrac{6}{5}&\text{for $-4 < x < 1$}\\\\\dfrac{9}{4}x-\dfrac{13}{4}&\text{for $1\le x\le 5$}}\end{cases}[/tex]

Step-by-step explanation:

You want the piecewise function that describes the relation shown in the graph.

The relation shown consists of three line segments connecting the points ...

  (-6, 5) and (-4, -2)

  (-4, -2) and (1, -1)

  (1, -1) and (5, 8)

The equations for the lines between the pairs of points can be written using the slope formula and the point-slope equation of a line.

The slope formula tells you the slope is ...

  m = (y2 -y1)/(x2 -x1)

And the point-slope equation of a line is ...

  y -y1 = m(x -x1)

If we add y1 to the equation of the line, and substitute the equation for m, we get ...

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1 . . . . . . a 2-point formula for a line

Between x-values -6 and -4, the equation of the line will use the first pair of points:

  y = (-2 -5)/(-4 -(-6))(x -(-6)) +5

  y = -7/2(x +6) +5 = -7/2x -16

Between x-values -4 and 1, the equation of the line will use the second pair of points:

  y = (-1-(-2))/(1 -(-4))(x -(-4)) +(-2)

  y = 1/5(x +4) -2 = 1/5x -6/5

Between x-values 1 and 5, the equation of the line will use the last pair of points:

  y = (8 -(-1))/(5 -1)(x -1) +(-1)

  y = 9/4(x -1) -1 = 9/4x -13/4

The piecewise function uses the equation for the line that is applicable for the appropriate x-values. We have listed those sets of x-values above.

We need to make sure that the function has only one definition for any given value of x. When two segments have a point in common, we need to make sure only one segment includes it.

  [tex]y=\begin{cases}-\dfrac{7}{2}x-16&\text{for $-6\le x\le-4$}\\\\\dfrac{1}{5}x-\dfrac{6}{5}&\text{for $-4 < x < 1$}\\\\\dfrac{9}{4}x-\dfrac{13}{4}&\text{for $1\le x\le 5$}}\end{cases}[/tex]

The likelihood of each possible occurrence is displayed on the y-axis of a probability histogram. A histogram is a statistical data display that makes use of rectangles to illustrate the frequency of data items in successive numerical intervals of equal size. The dependent variable is plotted along the vertical axis in the most typical type of histogram, while the independent variable is plotted along the horizontal axis. The distribution of data is depicted graphically in a histogram. A collection of neighboring rectangles, each with a bar that represents a certain type of data, is used to illustrate a histogram. Fill L1 with the values of the random variable (remember to use the class midpoints for continuous random variables). The associated percentages should be entered into L2 with a decimal format.

The solution for the quadratic equation is -5/2, 2/3

Given,

The equation: 18a² - 30 = -33a

We have to solve this equation

We can convert this equation into a quadratic equation:

18a² + 33a - 30 = 0

Now lets solve this quadratic equation with quadratic formula:

Quadratic formula = [tex]\frac{-b(+-)\sqrt{b^{2}-4ac } }{2a}[/tex]

Here,

a = 18, b = 33 and c = -30

Now we can solve:

[tex]\frac{-b(+-)\sqrt{b^{2}-4ac } }{2a}[/tex]

= [tex]\frac{-33(+-)\sqrt{33^{2} -4(18)(-30)} }{2(18)}[/tex]

=  [tex]\frac{-33(+-)\sqrt{1089-(-2160)} }{36}[/tex]

= [tex]\frac{-33(+-)\sqrt{1089+2160} }{36}[/tex]

= (- 33 ± √3249) / 36

= (- 33 ± 57) / 36

Solve for:

(- 33 + 57) / 36 = 24/36 = 2/3

Solve for:

(- 33 - 57) / 36 = - 90/36 = - 30/12 = -10/4 = -5/2

That is, the solution for the quadratic equation is -5/2, 2/3

The equation for two different bowling alleys is 2x - 3y = -2

This is a problem from algebraic equations. We can solve this problem by following a few steps.

In the first case, he paid $7 to rent a pair of shoes and x dollars an hour to bowl and bowled for 2 hours on Friday.

Here, the cost to bowl for one hour is x dollars. So, the cost to bowl for 2 hours is ( 2× x ) = 2x

Now, the total expenditure for shoes and to bowl is, (2x + 7) dollars

In the second case, he paid $5 to rent a pair of shoes and y dollars an hour to bowl and bowled for 3 hours on Saturday.

Here, the cost to bowl for one hour is y dollars. So, the cost to bowl for 3 hours is (3 × y) = 3y

Now, the total expenditure for shoes and to bowl is, (3y + 5) dollars.

As the total expenditure is the same in these two cases. Therefore, we can conclude,

(2x + 7) = (3y + 5)

Or, 2x - 3y = -2

The equation in slope-intercept form that represents the function is: g(x) = -2x + 1.

To write the slope-intercept form of an equation that represents the linear function g, find the slope (m) of the line and determine the y-intercept (b) of the line, then substitute the values into g(x) = mx + b.

Slope of the line that represents function g = change in y/change in x = -6 units/3 units

Slope of the line (m) = -6/3

Slope of the line (m) = -2.

The line intercepts the y-axis at y = 1, therefore the y-intercept (b) of the linear function is b = 1.

To write the equation representing the function, substitute m = -2 and b = 1 into g(x) = mx + b:

g(x) = -2x + 1

we have that the midpoint is (-2,-7)

and the endpoint is (12,-9)

We remember the midpoint formula:

Where (x1,y1) are the coordinates of one endpoint and

(x2,y2) are the coordinates for the other endpoint.

Here, we are trying to find (x2,y2) given that

(x1, y1) ---> (12, -9)

And since we also know the midpoint M(-2, -7), making a comparison with this and the midpoint formula, we get two equations, the first one is:

substituting x1 and solving for x2:

And now, with the second equation which is:

we substitute y1 and solve for y2:

Given,

If the perimeter of the triangle is 33 inches, then we have to find the sides of the triangle.

Let x be the sides of the triangle, we know that the triangle has 3 sides.

And lest us consider this one as equilateral triangle.

So, the formula for perimeter is,

Perimeter = 3 x sides
