Answer:

Peta can only use the zero product property when the product of factors is equal to zero.

Peta must multiply x by (x - 5).

Peta must write the equation in standard form, then factor the expression.

Each factor must be set equal to zero, not 20.

the graph of the function y=tan(x) was horizontally stretched so that it became 10x which is the equation of the transformed fun

Alborosie

Answer:

$y=tan \frac{x}{10}$

Step-by-step explanation:

The base of the tangent functions is $y=\tan x$ .

This is also called the parent tangent function that has a period of $\pi$ .

The transformation that stretches the graph of $y=\tan x$ horizontally by a factor of B is $y=\tan \frac{x}{B}$

From the question, the basic tangent function was stretched horizontally by a factor of 10.

This implies that $B=10$

The equation of the transformed function is $y=tan \frac{x}{10}$

The period of this function is $10\pi$

See how $y=tan \frac{x}{10}$ (red graph) is horizontally stretched as compared to $y=\tan x$ (blue graph) in the attachment.

Evaluate Combination (6,6)

andrew11 [14]

Answer:

$nCx = \frac{n!}{x! (n-x)!}$

On this case n =6 and x =6 we got:

$6C6 = \frac{6!}{6! (6-6)!} = \frac{6!}{6! 0!}= \frac{6!}{6!}=1$

Step-by-step explanation:

The utility for the combination formula is in order to find the number of ways to order a set of elements

For this case we want to find the following expression:

$6C6$

And the general formula for combination is given by:

$nCx = \frac{n!}{x! (n-x)!}$

On this case n =6 and x =6 we got:

$6C6 = \frac{6!}{6! (6-6)!} = \frac{6!}{6! 0!}= \frac{6!}{6!}=1$
