We need to know about roots of a quadratic equation to solve the problem. The quadratic equation is [tex]x^{2} -3x-40=0[/tex]

Quadratic equation is an equation with the highest degree of the variable being 2. A quadratic equation has two roots. The two roots can be real and different or real and equal or imaginary. The roots of a quadratic equation can be found using factorization method. The roots of a quadratic equation can be used to find the quadratic equation itself. Here in this question we have two points (-5,0) and (8,0). These points lie on the x-axis hence we can say that they are the two roots of the equation and the quadratic equation is in terms of x since it cuts the x-axis. Hence we can say that the two roots of the equation are -5 and 8.

For a quadratic equation [tex]ax^{2} +bx+c=0[/tex] let us say that the roots are α and β

α+β=-b/a

αβ=c/a

Here α and β are -5 and 8

-5+8=-b/a ⇒b/a=-3

c/a=-5 x 8=-40

The quadratic equation is given by [tex]x^{2} +\frac{b}{a} x+\frac{c}{a} =0[/tex] which is [tex]x^{2} -3x-40=0[/tex]

Therefore we found the quadratic equation using the two points given, the equation is [tex]x^{2} -3x-40=0[/tex]

A men’s traditional haircut at the Barbara spot cost $20 and a shave cost $25 there is an 8.25% state sales tax what is the total price that Cheyenne must pay if she gets his haircut and beard shaved and he tips the barber 25%

Answers

The total price that Cheyenne must pay if he gets his haircut and beard shaved $60.89

A sales tax is one that applies to the purchase of goods and services for consumers and to the sale of goods and services for businesses. It's a type of consumption tax, meaning it taxes people for spending money.

The formula for calculating the sales tax on a good or service is: selling price x sales tax rate, and when calculating the total cost of a purchase, the formula is:

total sale amount = selling price + sales tax.

Given that

spot cost = $20

shave cost =  $25

state sales tax = 8.25%

tips = 25%.

find out  the total price that Cheyenne pay.

total selling price = spot + shave cost

total selling price = $20 + $25

total selling price = $45

we know that

sales tax = selling price x sales tax rate

sales tax = $45 x 8.25%

sales tax = $45 x 8.25 / 100

sales tax = $3.7125.

Cost with sales tax = $45 + $3.7125

Cost with sales tax = $48.7125

Tip is calculated on total bill

Tip Total: $ 12.18

Total (Bill + Tip): $ 60.89

hence , total amount of $ 60.89 is that Cheyenne must pay if he gets his haircut and beard shaved with the bill and tip.

Answers

The statement that best describes the expression p-1(x) is (c) the amount for x grams

How to complete the statements?

The equation of the function is given as

P(n) = 0.2n + 5.3

(a) which statement best describes (p^-1) (x)?

The function is given as

P(n) = 0.2n + 5.3

This means that the inverse of the function is represented as p-1(n)

Hence, the statement that best describes the expression p-1(x) is (c) the amount for x grams

(b) The function p^-1 (x)

We have

P(n) = 0.2n + 5.3

Rewrite as

y= 0.2x + 5.3

Swap x and y

x = 0.2y + 5.3

Make y the subject

y = 5x - 26.5

Express as inverse function

p^-1(x) = 5x - 26.5

(c) The value of p^-1 (6.6)

We have

p^-1(x) = 5x - 26.5

This gives

p^-1(6.6) = 5 x 6.6 - 26.5

write an equation in slope- intercept form for the line described.
perpendicular to y = 1/4x + 2 passes through (0,0)

Answers

Answer:

y=-4x+0

Step-by-step explanation:

Slope form is y=mx+b

m is the slope, and b is the y intercept. If the line must pass through (0,0) then the y intercept would be zero.

This give you y=mx+0

Now to find the slope you need a perpendicular line to the previous line. This would mean you have to swap 1/4 which is the previous lines slope.

1/4 is a positive so make it a negative, -1/4

Now flip -1/4 to make is -4/1 which also equals -4

Now with the slope -4 and y-intercept 0, you know you equation

Answers

Answer:

x < 0

Step-by-step explanation:

We are given this inequality:

3x + 4 < 4

And we want to solve it.

Solving inequalities is very similar to solving equations. We want to isolate the variable (in this case, x) on one side, while leaving the numbers on the other side.

To start, we can subtract 4 from both sides.

3x + 4 < 4

    -4     -4

__________________

3x < 0

Now, we have the numbers on one side and the variable on the other, but we aren't done yet, as we want to solve for the value of x, or 1x, not the value of 3x.

So, we'll need to divide both sides by 3.

Graph the following system of inequalities on the coordinate plane. You will need to explain your work. Each correct line graphed WITH the correct explanation and shading is worth TWO points.
Please tell me how you graphed each line and how you determined where to shade

Answers

Answer:

See attached graphs Graph1, Graph2 and Graph3 and detailed explanation below

Step-by-step explanation:

The process for plotting and shading are essentially the same but with different inequalities

To plot any line

We need two pointsPlug in a value for x and find the corresponding y valueRepeat for another x value and find the corresponding y valueDraw a straight line through the two points

To determine area to shade

Choose a point on either side of the line from the graph. See if the corresponding (x,y) values satisfy the inequality. If they do, then that's the area to shade. If not, shade the other area

1. Inequality y > -3x - 2

The line equation is y = -3x -2

Let's choose x = 0. Then y = -3(0) -2 = -2. So one point is (0, -2)

Choose another value for x, say x = 1

y = -3(1) - 2 = -3-2 = -5. So another point is (1,-5).

Draw a straight line through both points (see attached Graph1)

Determining area to shade

Choose a point on the graph on one side of the line. Let's choose (1,2). So x = 1 and y = 2. Does this satisfy the inequality y = -3x -2? Let's see

Is 2 > -3(1) - 2 ?

2 > -3-2 ?

2 > -5 ? YES since a positive number is greater than a negative number. So the area containing (1,2) should be shaded as shown in Graph 1

2. Inequality 4x + 5y ≤ 20

Line equation is  4x + 5y =20

Convert to a function of x as follows

Subtract 4x from both sides ==> 5y = 20 -4xDivide by 5 both sides ==> y = 20/5 - (4/5)x  ==> y = 4- 4x/5

Choose two values of x and find corresponding y values to get the coordinates of two points

Plug x = 0 into line equation ==> y = 4- 4x/5

==> y = 4 - 4(0)/5 = 4

==> (0, 4) is one point

Choose another value of x, say 5(this is a convenient value since we are dividing by 5)

==> y = 4- 4(5)/5 = 4-4 = 0

==> (5, 0) is another point

Draw straight line through (0,4) and (5,0)

To determine area to shade let's choose a point on the graph. (0,0) is a convenient point.  Do the values of x=0 and y=0 satisfy the inequality
4x + 5y ≤ 20?

Plugging in x = 0 and y = 0 gives us

4(0) + 5(0) = 0 and 0 is indeed ≤ 20

So the inequality is satisfied at (0,0)

Shade the region on the side of the line where (0,0) is (see Graph2)

3. Inequality y > -4

The line equation is y = -4

Since this equation does not involve x, the line plot will be a horizontal line at y = -4 for all x values

Simply draw a horizontal line which crosses the y axis at y = -4

To determine which area to shade, choose a point. Use (0,0)

Does y = 0 satisfy the inequality y > -4?

0 > -4 so indeed the point (0,0) satisfies the inequality. Just shade the area on the side of the line which contains (0,0). This will be the region above the line y = -4 See Graph3

Hope that helps :)

many took both Calculus and Physics? Illustrate using a Venn diagram.

Answers

No student took both calculus and physics out of the 30 students.

Given that, total number of students are 30. Out of which 18 took calculus and 12 took physics. Then, we have to calculate how many took both calculus and physics. So, by using venn diagram we have,

Total number of students = 30

Students who took calculus = P(A) = 18

Students who took physics = P(B) = 12

Students who took both calculus and physics = P(A∩B) = x

Students who took only physics = P(B)-x = (12-x)

Students who took only calculus = P(A)-x = (18-x)

From venn diagram, we get

(18-x)+x+(12-x) = 30

18-x+x+12-x = 30

⇒ x = 0

∴ P(A∩B) = 0

Therefore, No student took both physics and calculus.

Answers

The loss percentage of cloth is 12.5%.

Stock of cloth = Rs. 1,60,000

worth of destroyed cloth = Rs. 20,000

A percentage is a number or ratio that can be expressed as a fraction of 100. It is denoted by the symbol %.

Percentage = Value/ Total value × 100%

Loss percentage = Loss/Total value × 100%

So, the loss percentage of cloth = 20,000/1,60,000 ×100%

                                                   = 0.125 × 100%
