Dr. Smith purchased a used car for $11,325. Her state charges 8% tax for the car, $53 for the license plates, and $40 for a state safety and emissions inspection. How does she need to play for these extra charges, not including the price of the car?

Answers

Answer:

999

Step-by-step explanation:

8% of 11,325 is 906

53 plus 40 is 93

906 plus 93 is 999

What was the cost of each teacup?

Answers

Using a linear equation, we find c using:

[tex]42 = 18 + 4c[/tex]

A linear function has the following format:

[tex]A(n) = A(0) + cn[/tex]

In which:

c is the slope, which is the price per unit.A(0) is the y-intercept, which is the fixed price.

In this problem, fixed price of $18, hence [tex]A(0) = 18[/tex]

She bough 4 units, and it cost $42, hence: [tex]n = 4, A(n) = 42[/tex]

Then

[tex]A(n) = A(0) + cn[/tex]

[tex]42 = 18 + 4c[/tex]

Hence, the equation to find c is:

[tex]42 = 18 + 4c[/tex]

what is the greatest number of relative maximum that a polynomial of degree 15 can have? Select the right answer among them 1. 14 2. 6 3. 9 4. 7 5. 4

Answers

Answer:

7

Step-by-step explanation:

The greatest number of relative maxima it can have is 14.

So, the correct answer would be option (1) 14.

Use the concept of a polynomial defined as:

An expression that consists of exponents, variables, and constants and that is combining many different mathematical procedures:

Addition, subtraction, and multiplication is referred to as polynomial.

Given that,

The degree of polynomial  = 15

The objective of this question determine the number of relative maxima it can have.

The number of relative maxima that a polynomial can have is equal to its degree minus 1.

In this case:

The polynomial is of degree = 15,

Hence,

The greatest number of relative maxima it can have is 15 - 1 = 14.

So, the correct answer would be option (1) 14.

Jacob has a headache. He can't stand long lists. "Can you repeat that again?" he asks. "It's easy. Name a number that is greater than 10, less than 20, is a multiple of 7, and FINALLY is a factor of 42," Replies Eric.

Answers

i think it would be 14. greater than 10 and less than 20. 42/3 is 14 and 7 times 2 is 14

Answer:

Well here are the constraints given to us here

Lets make this number “x”

x > 10

x< 20

7x

X = 1, 2, 6, 7, 21, 42

So with all this we can come up with this

10 < 7x < 20 = 1, 2, 3, 6, 7, 14, 21, 42

So lets cut this down a bit

It’s gotta be a multiple of 7 so we can get rid of 3 of the solutions

It can be 7, 14, 21, 42

Now it has to be more then 10 but less then 20

So that gets rid of everything except 14

infinite number of solutions

Step-by-step explanation:

x - ([tex]\frac{x}{5}[/tex] + 60) = [tex]\frac{4}{5}[/tex] x - 60 ← distribute parenthesis on left by - 1

x - [tex]\frac{x}{5}[/tex] - 60 = [tex]\frac{4}{5}[/tex] x - 60 , collect like terms on left side

[tex]\frac{4}{5}[/tex] x - 60 = [tex]\frac{4}{5}[/tex] x - 60

Since expressions on both sides are equal then any value of x is a solution.

That is there is an infinite number of solutions

Select the number line model that matches the expression | -6 - (-3)∣

Answers

-6 - (-3) remember ( a number in between ) this means positive number so that would mean that that equation would be 3
The absolute value means the value in side will be positive. - - or 2 negative signs give a positive number (cancel each other out). So it becomes -6 plus 3 which is -3. This would be the answer but absolute value signs mean that this value inside (-3) has to be positive.
The correct answer is a number line that shows 3.
