. Multiplying the denominator by
gives
![x^2(x^2+2x+8)=x^4+2x^3+8x^2](https://tex.z-dn.net/?f=x%5E2%28x%5E2%2B2x%2B8%29%3Dx%5E4%2B2x%5E3%2B8x%5E2)
Subtracting this from the numerator gives a remainder of
![(x^4+x^3+7x^2-6x+8)-(x^4+2x^3+8x^2)=-x^3-x^2-6x+8](https://tex.z-dn.net/?f=%28x%5E4%2Bx%5E3%2B7x%5E2-6x%2B8%29-%28x%5E4%2B2x%5E3%2B8x%5E2%29%3D-x%5E3-x%5E2-6x%2B8)
. Multiplying the denominator by
gives
![-x(x^2+2x+8)=-x^3-2x^2-8x](https://tex.z-dn.net/?f=-x%28x%5E2%2B2x%2B8%29%3D-x%5E3-2x%5E2-8x)
and subtracting this from the previous remainder gives a new remainder of
![(-x^3-x^2-6x+8)-(-x^3-2x^2-8x)=x^2+2x+8](https://tex.z-dn.net/?f=%28-x%5E3-x%5E2-6x%2B8%29-%28-x%5E3-2x%5E2-8x%29%3Dx%5E2%2B2x%2B8)
This last remainder is exactly the same as the denominator, so
divides through it exactly and leaves us with 1.
What we showed here is that
![\dfrac{x^4+x^3+7x^2-6x+8}{x^2+2x+8}=x^2-\dfrac{x^3+x^2+6x-8}{x^2+2x+8}](https://tex.z-dn.net/?f=%5Cdfrac%7Bx%5E4%2Bx%5E3%2B7x%5E2-6x%2B8%7D%7Bx%5E2%2B2x%2B8%7D%3Dx%5E2-%5Cdfrac%7Bx%5E3%2Bx%5E2%2B6x-8%7D%7Bx%5E2%2B2x%2B8%7D)
![=x^2-x+\dfrac{x^2+2x+8}{x^2+2x+8}](https://tex.z-dn.net/?f=%3Dx%5E2-x%2B%5Cdfrac%7Bx%5E2%2B2x%2B8%7D%7Bx%5E2%2B2x%2B8%7D)
![=x^2-x+1](https://tex.z-dn.net/?f=%3Dx%5E2-x%2B1)
and this last expression is the quotient.
To verify this solution, we can simply multiply this by the original denominator:
![(x^2+2x+8)(x^2-x+1)=x^2(x^2-x+1)+2x(x^2-x+1)+8(x^2-x+1)](https://tex.z-dn.net/?f=%28x%5E2%2B2x%2B8%29%28x%5E2-x%2B1%29%3Dx%5E2%28x%5E2-x%2B1%29%2B2x%28x%5E2-x%2B1%29%2B8%28x%5E2-x%2B1%29)
![=(x^4-x^3+x^2)+(2x^3-2x^2+2x)+(8x^2-8x+8)](https://tex.z-dn.net/?f=%3D%28x%5E4-x%5E3%2Bx%5E2%29%2B%282x%5E3-2x%5E2%2B2x%29%2B%288x%5E2-8x%2B8%29)
![=x^4+x^3+7x^2-6x+8](https://tex.z-dn.net/?f=%3Dx%5E4%2Bx%5E3%2B7x%5E2-6x%2B8)
which matches the original numerator.
Answer:
Angle, ![\theta=70.4^{\circ}](https://tex.z-dn.net/?f=%5Ctheta%3D70.4%5E%7B%5Ccirc%7D)
Step-by-step explanation:
We have, an A-frame house is 45 feet high and 32 feet wide. It is required to find the measure of the angle that the roof makes with the floor.
The attached figure shows the A frame. Let
is the angle that the roof makes with the floor. So,
![\tan\theta=\dfrac{45}{16}\\\\\tan\theta=2.81\\\\\theta=\tan^{-1}(2.81)\\\\\theta=70.4^{\circ}](https://tex.z-dn.net/?f=%5Ctan%5Ctheta%3D%5Cdfrac%7B45%7D%7B16%7D%5C%5C%5C%5C%5Ctan%5Ctheta%3D2.81%5C%5C%5C%5C%5Ctheta%3D%5Ctan%5E%7B-1%7D%282.81%29%5C%5C%5C%5C%5Ctheta%3D70.4%5E%7B%5Ccirc%7D)
So, the angle of 70.4 degrees is the angle that the roof makes with the floor.
Answer:
Directly proportional: as one amount increases, another amount increases at the same rate.
Inversely Proportional: when one value decreases at the same rate that the other increases.
Step-by-step explanation:
The profit of 5103.5 by making a prescription for 6 tablets.
<h3>What is percentage?</h3>
Percentage, a relative value indicating hundredth parts of any quantity.
The drug Viagra comes in a quantity of 30 tablets with an AWP of $900.
The insurer is willing to pay the AWP less 5% plus a $2.50
900/TAB = X 30 TABS =$27000
27000 * (0.05)= $1350
27000-1350.00
=$25650 + $2.50
=25652.5 for 30 tablets
For 6 tablets,
= (25652.5 / 30)*6
= 5103.5
