Find the following products:

baherus [9]

Answer:

i. x^2 – 1

ii. x^3 – 1

iii. x^4 - 1

Step-by-step explanation:

Products are obtained by multipliyng each left term by each rigth term as follows:

i. (x- 1)(x+ 1) = (x^2 – x + x - 1) = x^2 – 1 (equal terms with opposite sign substracts and the result is 0)

ii. (x- 1)(x^2 + x + 1) = (x^3 – x^2 + x^2 – x + x – 1) = x^3 – 1

iii. (x- 1)(x³ + x² + x + 1) = (x^4 – x^3 + x^3 – x^2 + x^2 – x + x – 1) = x^4 - 1

Simplify the expression.

levacccp [35]

Hi there! The answer is 30.

We need to use PEMDAS to simplify.
P = parenthesis
E = Exponents
M = Multiply
D = Dividing
A = Adding
S = Subtracting

$10(4 \times 10 \div ( {6}^{2} - {4}^{2} ) + 1)$
First find the exponents inside the middlest parenthesis.

$10(4 \times 10 \div (36 - 16) + 1)$
Now add inside the parenthesis.

$10(4 \times 10 \div 20 + 1)$
Multiply inside the parenthesis that are left.

$10(40 \div 20 + 1)$
Divide inside the parenthesis

$10(2 + 1)$
Add inside the parenthesis.

$10(3)$
Multiply.

$30$
~ Hope this helps you!

Which of the following equations is a constant function? y = x y = 5 x = 5

Mamont248 [21]

Answer:

Second Option

$y = 5$

Step-by-step explanation:

A constant function is one for which the range does not change regardless of the value of the domain.

$f (x_1) = f (x_2) = f (x_3) = m$

Where m is a constant.

The constant functions are horizontal lines parallel to the axis of the x

Note that

$y = x$ is not a constant function because the value of y changes when x changes.

x = 1, y = 1

x = 2 y = 2

$x = 5$ is not a constant function because the range of the function is not constant. $x = 5$ is a vertical line

$y = 5$ is a constant function, since for any of the value of x, the value of y will always be 5

Anyone know what this is.

gizmo_the_mogwai [7]

Answer:

The answer is 1/8 because 1/2 as a decimal is 0.5 so do 1/2 and get 0.5 then you do 0.5 divided by 4 which is 0.125 and 0.125 as a fraction is 1/8
