What's the domain and range for (×+4)-1
Sonja [21]
\bf a^{-{ n}} \implies \cfrac{1}{a^{ n}}\qquad \qquad

\cfrac{1}{a^{ n}}\implies a^{-{ n}}\\
---------------\\
thus\\
(x+4)^{-1}\implies \cfrac{1}{x+4}
\\\\

\bf if\qquad \cfrac{1}{0} \implies undefined

so.. what value of "x" makes x+4 to 0?

the domain will be, all real numbers, except that value

about the range, "y" will take, whateve "x" can provide.. in this case... I think is all real numbers, except 0, because, if you give a few big values to "x", the fraction will simply have a bigger and bigger denominator, making the fraction smaller and smaller, ever approaching 0, but never getting there

We have 25% off coupon for a Christmas tree already marked down to 10% if the original price of the tree is 189 how much will sh
Vladimir [108]

Answer:

She will pay $122.85

Step-by-step explanation:

First, find the amount of the percents.

To do that, turn the percents into decimals.

25% --> 0.25

10% --> 0.10

Then, multiply each decimal with the original price.

189×0.25= 47.25

189×0.10= 18.90

Now that you have the amount of the percents, subtract both from the original price.

189- (47.25+18.90)

189-66.15= 122.85

What is the lateral area of a prism which has a lateral edge of 4 inches and has a regular pentagonal base with an edge of 12 in
Nat2105 [25]

Check the picture below.

so the pentagonal prism in the picture is been seen from the bottom, namely so we can see its base, however the base is at the bottom, what does that mean, it means that the pentagonal bases are the top and bottom of the prism, that matters, because the other sides are the lateral sides.

so, if we notice, the lateral sides are really just 5 rectangles, each one a 12x4, so if we simply get the area of all those rectangles.

5(12 * 4) = 240 in².
