Answer:

Step-by-step explanation:

A is 0.5 x 10 because the thickness of the sheets is 0.5 and there are ten sheets stacked together that thickness so how thick is the pile.

for c just add another sheet on all sides wich is + 0.5 for each side and when you get that add that number to answer B and that it.

The graph of f(x)=cos(x) is transformed to a new function, g(x) , by reflecting it over the x-axis and shifting it 2 units down.

Levart [38]

Answer:

The equation of the new function is $g(x) = -cos(x) - 2$

Step-by-step explanation:

Vertically reflecting a function F(x), and calling it G(x) is the same as:

G(x) = -F(x)

In this problem, we have that:

$f(x) = cos(x)$

$g(x) = -cos(x)$

Shifting a function g down 2 units is the same as:

g(x) = g(x) - 2

$g(x) = -cos(x) - 2$

The equation of the new function is $g(x) = -cos(x) - 2$

B) A white shirt costs $. 2.50, and a blue shirt costs $. 1.50

djyliett [7]

<h3>Answer :</h3>

Cost of white shirt = 2.50 $

Cost of blue shirt = 1.50 $

We have asked to find percentage difference $.$

_________________________________

$:\implies\sf\:\dfrac{cost_{blue}-cost_{white}}{cost_{blue}+cost_{white}}\times 100$

$:\implies\sf\:\dfrac{2.50-1.50}{2.50+1.50}\times 100$

$:\implies\sf\:\dfrac{1}{4}\times 100$

$:\implies\:\boxed{\bf{\gray{25\:\%}}}$
