Answer:

45/8

Step-by-step explanation:

-45 represents a loss of 45 yards (integers include negative numbers)

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

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

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

The exponent of the power function is 1/2.

How often we are multiplying a number by itself is indicated by its exponent. To multiply 3 four times, for instance, we get 34. It is 3333 in its enlarged form. A number's power is another name for an exponent. It may take the form of an integer, a fraction, a negative integer, or a decimal.

A fractional exponent is one where the exponent of a number is a fraction. Parts of fractional exponents include square roots, cube roots, and nth roots. Square root of the base is a number having a power of half.

Hence we get the exponent of the function as 1/2.

Answer:c

Step-by-step explanation:

c

Answer:

Either 40 or 80, depending on whether you worded the question correctly or not.

Step-by-step explanation:

If you mean he has gone 80 miles:

velocity is distance per time, so 80miles/2hours = 40 miles/hour

If you mean he is going 80mph, then the answer is in the question, 80 miles/hour and the distance he has traveled is in miles, therefore you need to multiply by hours, i.e., 80*2=160 miles.

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

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

Evaluate

p^-1(6.6) = 6.5

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]

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

The representation of x^pi in base e is e^xln3.

An exponential function is a the kind of mathematical function that involves exponents.

       f (x) = aˣ

where x is a variable and an is a constant known as the function's base.

        f (x) = eˣ

When the exponent in this component increases by one, the function's value increases by a factor of e.

When the exponent is reduced by one, the value of the function is reduced by the same factor (it is divided by e ).

        f ( x ) = 10ˣ

Now, for the given function.

3x=e^ln3^x

Jenna paid a total interest of $4810 (13% of the cost of the car) for the car.

Suppose there is initial amount as P.

The interest, or say charge on it is applied annually as 'C' amount.

Taking how much percent of P is C, we get:

[tex]APR = \dfrac{C}{P} \times 100[/tex]

WE have been given that Jenna bought a new car for $37,000 and paid a 10% down payment and financed the remaining balance for 72 months with an APR of 6.5%

Assuming that she makes monthly payments, to determine the total interest Jenna pays over the life of the loan.

The cost = $37,000

Time = 72 months

APR = 6.5%

Then;

Interest = (37,000 x 6.5 x 2) /100

= $4810

Percentage of interest paid = (4810/37,000 ) x 100

= 13%

Therefore, Jenna paid a total interest of $4810 (13% of the cost of the car) for the car.

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

The approximate rate of change of the function is 224.95

The rate of change of the given function is expressed according to the equation below;

f'(x) = f(b)- f(a)/b-a

Given the interval [-4, 3]

a = -4

b = 3

f(a) = 9(-4)⁴ + 7/(-4)²

f(-4) = 2304+ 7/16

f(-4) = 2304.4375

f(b) = 9(3)⁴ + 7/(3)²

f(3) = 729 + 7/9

f(3) = 729.7778

Substitute to have:

f'(x) = 729.7778-2304.4375/3+4
