Answer:

x4+7x3-2x2-9x-3 remainder -10

or we could write it as

x4+7x3-2x2-9x-3 - 10/(x+8)

Step-by-step explanation:

x+8 ) x5+15x4+54x3−25x2−75x−34 (x4+7x3-2x2-9x-3  <--- Quotient.

        x5+ 8x4

                7x4+54x3

                7x4+56x3

                         -2x3-25x2

                         -2x3-16x2

                                    -9x2-75x

                                    -9x2-72x

                                               -3x-34

                                               -3x-24

                                                     -10  <--- Remainder.

Evaluate x2/y + x2/z for x = 6, y = -4, and z = -2.<br> -27<br> -9<br> 9<br> 27
Orlov [11]
<h2>Answer:</h2>

The value of the given expression is -27.

<h2>Given: </h2>

\frac{x^{2}}{y}+\frac{x^{2}}{z}

<h2>Step-by-step explanation: </h2>

In this problem, we need to solve the given expression in which we need to find the values of the variables. Since, the values of the variables are given, we can substitute the values and solve the equation as numerical calculation.

On substituting the values,

\Rightarrow \frac{x^{2}}{y}+\frac{x^{2}}{z}=\frac{(6)^{2}}{-4}+\frac{(6)^{2}}{-2}

On squaring the values in the numerator,

\Rightarrow \frac{x^{2}}{y}+\frac{x^{2}}{z}=-\frac{36}{4}-\frac{36}{2}

On cancelling the numerator and denominator,  

\Rightarrow \frac{x^{2}}{y}+\frac{x^{2}}{z}=-9-18

On adding,

\Rightarrow \frac{x^{2}}{y}+\frac{x^{2}}{z}=-27

Identify the hyperbolas (represented by equations) whose centers are at (2, 1)
weqwewe [10]
When the transverse axis is horizontal, a hyperbola centered at (h,k) has formula (x-h)^2/a^2-(y-k)^2/b^2=1. Plug in h=2, k=1, the formula is (x-2)^2/a^2-(y-1)^2/b^2=1 for some a,b. If the transverse axis is vertical, the formula is (y-h)^2/a^2-(x-k)^2/b^2=1, and (y-2)^2/a^2-(x-1)^2/b^2=1 in our case.

Simplify the expression -3y-(8y+1)
drek231 [11]
−3y−(8y+1)

Distribute the Negative Sign:

=−3y+−1(8y+1)

=−3y+−1(8y)+(−1)(1)

=−3y+−8y+−1

Combine Like Terms:

=−3y+−8y+−1

=(−3y+−8y)+(−1)

=−11y+−1

What is the APPROXIMATE circumference of a circle with a radius of 9 inches? Use 3.14 for π. 28.3 in. 56.5 in. 254.34 in. 113.0
Stella [2.4K]

Answer:

56.52 in

Step-by-step explanation:

Circumference Formula: C = 2πr

Since we are given radius <em>r</em> = 9, simply plug it into the formula:

C = 2π(9)

C = 18π

C = 56.5487
