What are the leading coefficient and degree of the polynomial?
-7 -10w^7+12w +
15w^9

Answers

Answer 1
Answer: Rewritten:
15w^9 - 10w^7 + 12w - 7

Leading coefficient: 15

Degree of the polynomial: 9
Answer 2
Answer:

Final answer:

The leading coefficient of the polynomial 15w9 - 10w7 + 12w -7 is 15 and the degree of the polynomial is 9.

Explanation:

The polynomial in question is -7 -10w7 + 12w + 15w9. To find the leading coefficient and degree of the polynomial, we need to reorder the terms from highest to lowest power of w. The proper order is 15w9 - 10w7 + 12w -7. In a polynomial, the leading coefficient is the coefficient of the term with the highest degree. So, the leading coefficient in this polynomial is 15. The degree of a polynomial is the highest power in the polynomial. Therefore, the degree of this polynomial is 9.

Hello,

In order to exist ,k>=0

1) sin (180°+x)=-sin (x) ==>sin(203°)=-√k

2) cos² x +sin² x=1==>cos x=√(1+sin² x)=√(1+k)

3)tan (-x)=-tan (x) =-sin (x)/cos (x) =- √k/√(1+k)=√(k/(1+k))

Work the following pricing problems for services rendered. (For all calculations use hundredths.)Labor time = 4 1/2 hours
Overhead rate = 95%
Retail price of parts = $134.75
Total cost of job = $241.98
Hourly rate?

Answers

Answer:

Hourly Rate = $12.22 per hour

Step-by-step explanation:

\text{Labor Time = }4\tfrac{1}{2}=4.5\thinspace{ hours}

Overhead Rate = 95%

Retail price of parts = $134.75

Total cost of job = $241.98

Cost of labor = Total cost - Retail price

                      = 241.98 - 134.75

                      = $107.23

Now, labor works for 4.5 hours and ears a total amount of $107.23

\implies\text{Amount earned in one hour or hourly rate = }(107.23)/(4.5)\n\n\implies \text{Hourly rate = }\$23.83\text{ per hour}

Now, Labor will get 95% overhead rate

⇒ The labor is getting 100% already but an overhead of 95% is also given

\text{So, Hourly Rate = }(23.83)/(1+0.95)\n\n\bf\implies\textbf{Hourly Rate = }\$12.22\textbf{ per hour}

For every increase of 1 on the Richter scale, an earthquake is 10 times more powerful. Which of the following models this situation?

a-linear function with a negative rate of change
b- linear function with a positive rate of change
c-exponential decay function
d-exponential growth function

answer-exponential growth function

Answers

The model that best describes this situation is an exponentialgrowthfunction.

The correct answer is option D.

What is a function?

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

Exponential growth function

The given situation describes how the power of an earthquake increases exponentially with an increase in Richter scale magnitude.
Specifically, for every increase of 1 on the Richter scale, the earthquake is described as being 10 times more powerful.

This is characteristic of exponentialgrowth, where a quantity increases by a fixed proportion for each unit increase in another variable.

In this case,

As the Richter scale magnitude increases by 1, the power of the earthquake increases by a factor of 10, which is an exponentialgrowth relationship.

Therefore,

The model that best describes this situation is an exponentialgrowthfunction.

Fandango has movie tickets on sale for 1\2 price. You buy 2 $12 tickets and you must pay 6% sales tax. What is your total cost after discount and taxes?​

Answers

Answer:

$12.72 or $25.44

Step-by-step explanation:

if he buys 2 tickets that are $12 each. half of 12 is 6 so you will have to pay 12 plus tax(6%). to find tax you would multiply 12 x .06 which would be $12.72. if it say the tickets are half off from $24 being $12 each then the answer would be $25.44. the question  dosent specify that.

hope i helped

Final answer:

The total cost after the discount and taxes would be $13.44.

Explanation:

To find the total cost after the discount and taxes, we first need to determine the discount amount.

Since the tickets are on sale for 1/2 price, the discount would be half of the original cost of the tickets.

So the discount amount would be 1/2 * $12 * 2 = $12.

Next, we need to calculate the sales tax, which is 6% of the original cost of the tickets.

The sales tax would be 0.06 * $12 * 2 = $1.44.

Finally, we can calculate the total cost by adding the original cost of the tickets, the sales tax, and subtracting the discount amount.

The total cost would be $12 * 2 + $1.44 - $12 = $13.44.
