Answer:

Start by using your first factor, 1. Substitute "1" for each "x" in the equation: (1)3 - 4(1)2 - 7(1) + 10 = 0.

This gives you: 1 - 4 - 7 + 10 = 0.

Because 0 = 0 is a true statement, you know that x = 1 is a solution.

What is the equation of the axis of symmetry of the graph of y + 3x – 6 = –3(x – 2)2 + 4?

asambeis [7]

ANSWER

$x =\frac{3}{ 2}$

EXPLANATION

The given equation is

$y + 3x - 6 = - 3(x - 2)^{2} + 4$

Expand the parenthesis:

$y + 3x - 6 = - 3( {x}^{2} - 4x + 4) + 4$

$y + 3x - 6 = - 3 {x}^{2} + 12x + - 12 + 4$

Write in standard form:

$y = - 3 {x}^{2} + 12x - 3x+ - 12 + 4 + 6$

$y = - 3 {x}^{2} + 9x-2$

where

$a=-3,b=9,c=-2$

The axis of symmetry is given by the formula:

$x = - \frac{b}{2a}$

Plug the values to get:

$x = - \frac{9}{ 2(- 3)}$

$x =\frac{3}{ 2}$

The equation of axis of symmetry is

$x =\frac{3}{ 2}$

What is the quotient of 1.888\times 10^91.888×10 9 and 5.9 \times 10^65.9×10 6 expressed in scientific notation?

Jlenok [28]

Given:

The expressions are $1.888\times 10^9$ and $5.9\times 10^6$ .

To find:

The quotient of $1.888\times 10^9$ and $5.9\times 10^6$ expressed in scientific notation.

Solution:

Quotient of $1.888\times 10^9$ and $5.9\times 10^6$ is:

$\dfrac{1.888\times 10^9}{5.9\times 10^6}=\dfrac{1.888}{5.9}\times \dfrac{10^9}{10^6}$

$\dfrac{1.888\times 10^9}{5.9\times 10^6}=0.32\times 10^{9-6}$

$\dfrac{1.888\times 10^9}{5.9\times 10^6}=0.32\times 10^{3}$

In the scientific notation, the first number is between 1 to 10. So, 0.32 can be written as $\dfrac{3.2}{10}$ .

$\dfrac{1.888\times 10^9}{5.9\times 10^6}=\dfrac{3.2}{10}\times 10^{3}$

$\dfrac{1.888\times 10^9}{5.9\times 10^6}=3.2\times 10^{3-1}$

$\dfrac{1.888\times 10^9}{5.9\times 10^6}=3.2\times 10^{2}$

Therefore, the value of the quotient is $3.2\times 10^{2}$ .
