Answer:

Step-by-step explanation:

Alright, lets get started.

The given polynomial is : $4m-2m^4-6m^2+9$

In the standard form, the highest power term is written first

Then second highest power is written and follows the same rule further

Here the highest power term is $-2m^4$

The second highest power term is $-6m^2$

The third highest power term is $4m$

Last term is 9

So, the standard form is :

$-2m^4-6m^2+4m+9$ : Answer

Hope it will help :)

The original price of a DVD is $25. The price is marked down 17% each month.

masya89 [10]

Answer:

$16.50

Step-by-step explanation:

First we have to find 17% of 25 so our equation is:

25 x 0.17 = 4.25

Then we have to find how much we have to mark down from the original price so our equation is:

4.25 x 2 = 8.5

Then we have to take 8.5 off of the original price:

25 - 8.5 = 16.5

So the price is $16.50 after 2 months

Your cousin Vinny wants to borrow $23750. He’s willing to pay you back over 8 years with simple interest. Your alternative is to

kolbaska11 [484]

Answer:

A)You will earn $20311.62 as interest if you deposit $23750 into an investment account for 8 years.

B) The annual interest rate to you charge Vinny in order to make the same amount of interest on his loan as your investment account is 10.69%

Step-by-step explanation:

We are given that Your cousin Vinny wants to borrow $23750. He’s willing to pay you back over 8 years with simple interest.

Your alternative is to invest in the $23750 into an account paying 7.75% compounded monthly.

a)How much interest would you earn in your investment if you deposit $23750 into an investment account for 8 years?

Principal = 23750

Rate of interest = 7.75%

No. of compounds per year = 12

Time = 8 years

Formula : $A=P(1+\frac{r}{n})^{nt}$

Where A is the amount

P is the principal

r = rate of interest

n = No. of compounds

t = time

Substitute the value sin the formula :

$A=23750(1+\frac{7.75}{1200})^{12 \times 8}$

A=44061.6163406

Interest = Amount - Principal

Interest = 44061.6163406-23750

Interest =20311.62

You will earn $20311.62 as interest if you deposit $23750 into an investment account for 8 years.

B)What annual interest rate to you charge Vinny in order to make the same amount of interest on his loan as your investment account

Principal = 23750

Simple interest = $\frac{P \times T \times R}{100}$

$20311.62=\frac{23750 \times 8 \times R}{100}\\\frac{20311.62 \times 100}{23750 \times 8}=R\\10.69\%=R$

Hence The annual interest rate to you charge Vinny in order to make the same amount of interest on his loan as your investment account is 10.69%

Triangle ABC is reflected over the X axis. TRIANGLE ABC has points A(10,2) B(9,5) C(6,4). What is the C coordinate

gavmur [86]

1. Let A(a,b) be a point in the coordinate axis. The reflection of A with respect to the x-axis is the point A'(a, -b).

2. So the reflection of C(6, 4) is C'(6, -4)

3. Remark, a picture is always helpful when dealing with reflections.

I need help with this trigonometry problem.

irina1246 [14]

The sum of all 3 angles in a triangle is 180
180-44=136
And you know that angle A is over 90 degrees so I believe it is 100 leaving angle b to be 36

What is the equation (4, 5) m=-1/4 solved in point slope form?

hammer [34]

Answer:

Step-by-step explanation:

The point-slope form of an equation of a line:

$y-y_1=m(x-x_1)$

We have m = -1/4 and the point (4, 5). Substitute:

$y-5=-\dfrac{1}{4}(x-4)$
