Find the quotient and remainder when p (x) divides with g (x) question (i) P (x) = x raise to 4 - 3 x square +4x + 5, g (x) = x
Morgarella [4.7K]

Answer:  x^2-8+\dfrac{4x+5}{x^4-3x^2+4x+5}

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

P(x) = x⁴ - 3x² + 4x + 5

g(x) = x² + 5

         <u>_x²_- 8                           </u>

x² + 5) x⁴ + 0x³ - 3x² + 4x + 5

        -<u>(x⁴ + 0x³ + 5x²) </u>  ↓     ↓  

                         -8x² + 4x  + 5

                       -<u>(-8x² + 0x - 40)</u>

                                    4x + 45

\dfrac{x^4-3x^2+4x+5}{x^2+5}=\large\boxed{x^2-8+\dfrac{4x+5}{x^4-3x^2+4x+5}}

Alex is a member of the school track and field team. His times for running various distances are shown. Create a scatter plot fo
frozen [14]

Answer:

(1) Please find attached the graph of the data

(2) 160.396 m

(3) The correlation that exist is a straight line correlation

Step-by-step explanation:

The given data are;

Distance,         Time

(m),                    (s)  

50,                    6.1

100,                   12

150,                   18.3

200,                  25.2

250,                   31.7

(2)

Based on the linear regression formula, we have;

b = \dfrac{N\sum XY - \left (\sum X  \right )\left (\sum Y  \right )}{N\sum X^{2} - \left (\sum X  \right )^{2}}

b = \dfrac{5 \times 17215 - 93.3 \times 750}{5 \times 2156.03 -8704.89} = 7.758

a = \dfrac{\sum Y - b\sum X}{N}

a = \dfrac{750 - 7.7581 \times 93.3}{5}= 5.234

The line is

y = 7.7581×x+5.234

When t = 20 s, we have

y = 7.7581*20+5.234 = 160.396 m

(3) The correlation that exist is a straight line correlation

Which line plot displays a data set with an outlier?
Westkost [7]

Answer: See attached, the top right

Step-by-step explanation:

      <u>What is an outlier?</u> An outlier, in a data set, is a data value that is outside the overall pattern of distribution.

   This means the answer to your question is the top right because the data value of 13 is outside the overall pattern, hence an outlier.

A mathematical sentence which contains an inequality symbol and one variable raised to the first power is called a ____ inequali
STALIN [3.7K]
Inequality, in mathematics, statement that a mathematical expression is less than or greater than some other expression; an inequality is not as specific as an equation<span>equation,
in mathematics, a statement, usually written in symbols, that states the equality of two quantities or algebraic expressions, e.g., x+3=5. The quantity x

The symbols < (less than), > (greater than), ≤ (less than or equal to), and ≥ (greater than or equal to) are used in place of the equals sign in expressions of inequalities. As in the case of equations, inequalities can be transformed in various ways. The direction of the inequality remains unchanged if some number is added to both sides or subtracted from both sides or if both sides are multiplied or divided by some positive number; e.g., subtracting 10 from both sides of the inequality x < 8 gives x − 10 < −2, and multiplying the inequality by 2 gives 2x < 16. Multiplication or division by a negative number reverses the sign of the inequality; e.g., if −2x < 8, then dividing both sides by −2 results in the inequality x > <span>−4.</span>
