The formula for slope is the difference in y-values divided by the difference in x-values. the slope of a line is its steepness or its rate of change. There are 4 types of slopes positive, negative, zero, and undefined.

ANSWER

B. 81

EXPLANATION

The given expression is:

[tex] {3}^{ \frac{11}{5} } \div {3}^{ - \frac{9}{5} } [/tex]

Recall that:

[tex] {a}^{m} \div {a}^{n} = {a}^{m - n} [/tex]

We simplify the expression using the properties of exponents to obtain:

[tex]{3}^{ \frac{11}{5} } \div {3}^{ - \frac{9}{5} } = {3}^{ \frac{11}{5} - - \frac{9}{5} } [/tex]

We simplify the exponents to get;

[tex]{3}^{ \frac{11}{5} } \div {3}^{ - \frac{9}{5} } = {3}^{ \frac{11 + 9}{5}} [/tex]

[tex]{3}^{ \frac{11}{5} } \div {3}^{ - \frac{9}{5} } = {3}^{ \frac{20}{5}} [/tex]

[tex]{3}^{ \frac{11}{5} } \div {3}^{ - \frac{9}{5} } = {3}^{4} [/tex]

[tex]{3}^{ \frac{11}{5} } \div {3}^{ - \frac{9}{5} } = 81[/tex]

No he should have multiplied 5,700 by 0.05

Answer:

The correct option is B) No, he should have multiplied $5,790 by 0.05.

Step-by-step explanation:

Consider the provided information.

He is paid $14.00 per hour, plus 5% commission. He worked 8 hours and sold 6 computers today for a total of $5,790.

Now find his total earning as shown:

$14 × 8 = $112

It is given that he sold 6 computers for a total of $5,790 and he gets a commission of 5% of total sale.

5% = [tex]\frac{5}{100}=0.05[/tex]

Now multiply 0.05 with $5,790

$5,790 × 0.05 = $289.5

Hence, the total income is $112+$289.5=$401.5

To calculate his pay, Henry multiplies 14 × 8, then adds the product to 5,790, then multiplies the sum by 0.05.

Henry's calculation is incorrect as he needs to multiply 5,790 with 0.05 and then he need to add the product of 14 × 8

Therefore, the correct option is B) No, he should have multiplied $5,790 by 0.05.

Answer:

slope = - 6

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

y - 15 = - 6(x + 7) ← is in point- slope form

with slope m = - 6

The slope of the line that is represented by the equation y-15=-6(x+7) is -6.

The given equation is y-15=-6(x+7).

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The standard form of the slope intercept form is y=mx+c.

Where, m=slope and c=y-intercept

Here, y-15=-6(x+7) can be written as y-15=-6x-42

⇒ y=-6x-42+15

⇒ y=-6x-27

So, slope of an equation is -6.

Therefore, the slope of the line that is represented by the equation y-15=-6(x+7) is -6.

Answer:

1) g(x) ----> y-intercept -3

2) h(x) ----> y-intercept -1

3) f(x) ----> y-intercept 2

Step-by-step explanation:

we know that

The y-intercept or initial value, is the value of y when the value of x is equal to zero

Calculate the y-intercept of each exponential function

case 1) A function g, has a growth factor of 2 and a value of 1, and passes through the point (1,-2)

The exponential function is equal to

[tex]g(x)=1(2)^{x}+c[/tex]

Find the value of c

For x=1, g(x)=-2

substitute

[tex]-2=(2)^{1}+c[/tex]

[tex]-2=2+c[/tex]

[tex]c=-4[/tex]

so

[tex]g(x)=(2)^{x}-4[/tex]

Find the y-intercept

For x=0

[tex]g(0)=(2)^{0}-4[/tex]

[tex]g(0)=-3[/tex]

case 2) Observing the table

For x=0

f(0)=2

therefore

The y-intercept of f(x) is 2

case 3) Observing the graph

For x=0

h(0)=-1

therefore

The y-intercept of h(x) is -1

Order the functions from least to greatest y-intercept

1) g(x) ----> y-intercept -3

2) h(x) ----> y-intercept -1

3) f(x) ----> y-intercept 2

Final answer:

To find the y-intercept of an exponential function, evaluate it at x = 0. The constant term in the function represents the y-intercept. Order the functions by comparing these constant terms from least to greatest.

Explanation:

To find the y-intercept of an exponential function, we need to evaluate the function when x is equal to zero. The exponential function is usually given in the form f(x) =[tex]ab^x[/tex], where a is the y-intercept. This is because any number (except zero) raised to the power of zero is 1, so[tex]b^0[/tex] will always be 1, leaving us with f(0) = a.

After finding the y-intercept for each function, order them from least to greatest to complete the task. For example, if we have functions such as f(x) = [tex]2(3)^x, g(x) = 5(2)^x[/tex], and h(x) = [tex]-1(4)^x,[/tex] their y-intercepts would be 2, 5, and -1 respectively. Ordered from least to greatest, the functions by their y-intercepts would be h(x), f(x), g(x).

Answer:

B). graph of increasing exponential function going through point (0, 3)

Step-by-step explanation:

Given function is [tex]f\left(x\right)=3\left(1.5\right)^x[/tex]

Now we need to find about which of the given choices best describes the given function. Where given choices are:

A). graph of increasing exponential function going through point 0, 2

B). graph of increasing exponential function going through point 0, 3

C). graph of increasing exponential function going through point 0, 1

D). graph of increasing exponential function going through point 0, 4

plug x=0 into given function

[tex]f\left(x\right)=3\left(1.5\right)^x[/tex]

[tex]f\left(0\right)=3\left(1.5\right)^0=3(1)=3[/tex]

Hence graph passes through point (0,3).

growth factor 1.5 is greater than 1 so that means it is increasing function.

Hence correct choice is:

B). graph of increasing exponential function going through point (0, 3)

The pepperoni and peppers are mixed up

Step-by-step explanation:

Answer:

The mistake my friend made was that pepperoni and peppers are mixed up, pepperoni is suppose to be 20% while peppers is supposed to be 14%

Step-by-step explanation:

Given that 4000 students

Pepperoni = 800

Sausage = 1,000

Mushrooms = 1,200

Peppers = 560

Onions = 240

Other = 200

To find the degree of each on the circle graph, we have:

Pepperoni = 800/4,000 * 100 = 20%

Sausage = 1,000/4,000 * 100 = 25%

Mushrooms = 1,200/4,000 * 100 = 30%

Peppers = 560/4,000 * 100 = 14%

Onions = 240/4,000 * 100 = 6%

Other = 200/4,000 * 100 = 5%

The mistake my friend made is that pepperoni and peppers are mixed up, pepperoni is suppose to be 20% while peppers is supposed to be 14%

Step-by-step explanation:

12 seconds for 28 claps

1 second for (28/12) claps

? claps for 1.75 mins?

1.75 minutes = 105 seconds (1.75×60 = 105)

105 seconds for (28/12)×105 claps

= 245 claps

Answer:

Your friends can clap their hands 245 times in 1.75 minutes.

Step-by-step explanation:

First of all, you should know how many seconds represents 1.75 minutes, because the amount of applause your friends can make is in that measure of time.  In order to make this conversion, a simple rule of three is made, knowing that 1 minutes is 60 seconds:

If 1 minute is 60 seconds, how many seconds are 1.75 minutes?

[tex]\frac{1.75minutes*60seconds}{1minute} =105 seconds[/tex]

Knowing that your friend can clap his hands 28 times in 12 seconds and knowing that 1.75 minutes is 105 seconds, you can perform a rule of three again:

If they can clap their hands 28 times in 12 seconds, how many applause can they make in 105 seconds?

[tex]\frac{105seconds*28applause}{12} =245 applause[/tex]

Then your friends can clap their hands 245 times in 105 seconds, which is 1.75 minutes.

Answer:

Step-by-step explanation:

n, n + 1, n + 2 - three consecutive integers

The equation:

138 - n = (n + 1) + (n + 2)

138 - n = n + 1 + n + 2                 combile like terms

138 - n = 2n + 3           subtract 138 from both sides

-n = 2n - 135               subtract 2n from both sides

-3n = -135            divide both sides by (-3)

n = 45

n + 1 = 46

n + 2 = 47

The three consecutive integers in question are 45, 46, and 47. This was solved by setting up and solving a simple algebraic equation.

Let the three consecutive integers be x, x+1, and x+2. According to the problem, the sum of the second and third integers is equal to 138 minus the first one. This can be written mathematically as:

x + (x + 1) + (x + 2) = 138

Solving this equation gives:

3x + 3 = 138
3x = 135
x = 45

Hence, the three consecutive integers are 45, 46, 47.

To calculate the total amount Emilee will pay back under a finance agreement, one needs to know the specifics of the loan. Joanna's example, with a known interest rate and term, shows how to use the present value of an annuity formula to find out the maximum loan and total amount paid over time.

The question pertains to calculating the total amount that Emilee will pay back under a finance agreement for her purchase. To determine this amount, one must know the principal amount of the loan, the interest rate, and the term of the loan.

For instance, if Joanna can afford to pay $12,000 a year for a house loan at an annual interest rate of 4.2% for 30 years, one can use the formula for the present value of an annuity to calculate the maximum loan she can afford. The formula is PV = PMT [1 - (1 + i)^(-n)] / i, where PV is the present value (the maximum loan), PMT is the annual payment ($12,000), i is the interest rate per period (4.2% annually), and n is the number of periods (30 years).

By applying this formula, Joanna can afford a maximum loan of approximately $202,556.98. Over 30 years, she will end up paying $12,000 times 30, which equals $360,000 in total. Similarly, to determine the total amount Emilee will repay, the same types of calculations would apply based on the terms of her finance agreement.

The age of youngest friend = 14 years

Step-by-step explanation:

It is given that, four friends were born on consecutive years the sum of their ages is 62

Let 'x' be the age of youngest friend

age of other friends are (x + 1), (x + 2) and (x + 3)

To find the age of youngest friend

From the given information we can write,

x +  (x + 1) + (x + 2) + (x + 3) = 62

4x + 6 = 62

4x = 62 - 6 = 56

x = 56/4 = 14

Answer:

f(x) =  3(x + 2)(x - 1)(x + 3)

Step-by-step explanation:

A logical first step would be to factor 3 out of all four terms:

f(x) = 3x^3+12x^2+3x-18 = 3(x^3 + 4x^2 + x - 6)

Roots of this x^3 + 4x^2 + x - 6 could be factors of 6:  {±1, ±2, ±3, ±6}.

I would use synthetic division here to determine which, if any, of these possibilities are actually roots of x^3 + 4x^2 + x - 6.  Let's try x = 1 and see whether the remainder of this synth. div. is 0, which would indicate that 1 is indeed a root of x^3 + 4x^2 + x - 6:

1    /    1    4    1    -6

                1    5    6

    ------------------------

          1     5    6    0

Yes, 1 is a root of x^3 + 4x^2 + x - 6, and so (x - 1) is a factor of x^3 + 4x^2 + x - 6.

Look at the coefficients of the quotient, which are   1, 5 and 6.

This represents the quadratic 1x² + 5x + 6, whose factors are (x + 2) and

(x + 3).

Thus, the given polynomial in factored form is:

f(x) = 3x^3+12x^2+3x-18 = 3(x + 2)(x - 1)(x + 3)
