Answer:

\displaystyle \frac{x^4 + 10x^3 + 25x^2 + 3x - 24}{x^2 + 5x - 4} = x^2 + 5x - 4 + \frac{3x - 8}{x^2 + 5x - 4}

General Formulas and Concepts:

<u>Algebra I</u>

Terms/Coefficients

  • Expanding

<u>Algebra II</u>

Polynomial Division

  • Long Division
  • Synthetic Division

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify.</em>

<em />\displaystyle \frac{x^4 + 10x^3 + 25x^2 + 3x - 24}{x^2 + 5x - 4}<em />

<em />

<u>Step 2: Long Division</u>

<em>See attachment.</em>

  1. Multiply quotient <em>a</em> and divisor, then subtract from dividend:                      \displaystyle x^2(x^2 + 5x - 4) = x^4 + 5x^3 - 4x^2 \leftarrow \text{red 1}
  2. Multiply quotient <em>b</em> and divisor, then subtract from new dividend:              \displaystyle 5x(x^2 + 5x - 4) = 5x^3 + 25x^2 - 20x \leftarrow \text{red 2}
  3. Multiply quotient <em>c</em> and divisor, then subtract from new dividend:              \displaystyle 4(x^2 + 5x - 4) = 4x^2 + 20x - 16 \leftarrow \text{red 3}
  4. Write remainder:                                                                                               \displaystyle \frac{r(x)}{b(x)} = \frac{3x - 8}{x^2 + 5x - 4}

RSB [31]

Answer:

False

Step-by-step explanation:

2x+7=30

2x=23

X= 23/2 or 11.5

X does not equal 3, therefore the statement is false

If c is the hypotenuse of a right triangle,find the missing side. If necessary, round to the nearest hundredth. c=sqrt(155), b=s
Lunna [17]
A^2 + 31 = 155  - I squared each of b and c for those numbers
a^2 = 155 - 31
a^2 = 124
a = 4 * sqrt(31)

Manuel is riding his bike. The graph represents the distance Manuel travels from his house over time. Describe what is happening
olasank [31]

Answer:

Manuel is moving with a constant speed and reach his destination at 5 units distance from his house after 3 units of time.

He took rest at his destination for 4 units of time.

Then he reach his house at 5 units distance in 1 unit time.

Step-by-step explanation:

See the graph attached.

Manuel is riding his bike.

As the graph shows that Manuel starts his journey from his house and the time counts starts and then he is moving at a constant speed and reach his destination at 5 units distance from his house after 3 units of time.

The constant speed is \frac{5}{3} units.

Then he took rest at his destination for 4 units of time.

After that, he again starts to move towards his house at a constant speed and reach his house at 5 units distance in 1 unit time.

Therefore, his speed of return is \frac{5}{1} units. (Answer)

Using first principal find the gradient of the curve whose equation is y=x^5. show working pleas​
Keith_Richards [23]

Answer:

The gradient of y = x^{5} is \frac{dy}{dx} = 5\cdot x^{4}.

Step-by-step explanation:

Geometrically speaking, the gradient of a curve is the slope of the tangent line at a given point of the curve. From perspective of Differential Calculus, the gradient is the first derivative of the curve. Let y = x^{5}, then the gradient of the curve is:

\frac{dy}{dx} = 5\cdot x^{4} (1)

The gradient of y = x^{5} is \frac{dy}{dx} = 5\cdot x^{4}.
