At best buy they have a 42" TV that sells for $1250 and is on sale 15% and sales tax is 6%.What is the final cost?

Answers

ok so
sale is 15% off
and add 6% tax

100-15=85
100+6=106

therefor
1250 with 15% discount plus 6% tax means
1250 times 85% times 106% =
1250 times 0.85 times 1.06=1126.25
final cost=$1126.25

First Find 15% of the original price to find the sales price.

1250 x 0.15= 187.50

1250 - 187.50= 1062.5

Then to find your tax, multiply 1062.50 by 0.06.

1062.50 x 0.06= 63.75

Your total price would be: 1126.25 :)

Whats the smallest zero for the function y = 4x^2-8x 60

Answers

ok so
we don't know the sign so it could be
4x^2-8x+60 or
4x^2-8x-60
( if it is the first one, go to AAAAAAA
if it is second one go to BBBBBBBBBBB)

to find the zero fo the function, set the fnction to zero
then factor since if you had xy=0, then assume that x and y=0

AAAAAAAAAA
4x^2-8x+60=0
4(x^2-2x+15)=0
4 you get a nonreal root so the missing sign is probably a negative sign
if you were to graph this one, there is no x intercept

BBBBBBBBB
4x^2-8x-60=0
4(x^2-2x-15)=0
4(x-5)(x-3)=0
x-5=0
x=5
x-3=0
x=3
3<5
smallest zero is 3

I would say the smallest zero is 3

The smallest zero for your equation is either -3 or 2.
Since you didn't gave us what 60 was either positive or negative, I had to write it in both forms.
Which are y=4x^2-8x+60 or y=4x^2-8x-60.
If your equation has it with a positive 60 then the smallest zero is 2.
If your equation has it with a negative 60 then the smallest zero is -3.
If you need any further explanation due to how I got the answer just let me know. (:

How do you find similar triangles (equation?)

Answers

Two triangles are similar if they have:

all their angles equalcorresponding sides are in the same ratio

But we don't need to know all three sides and all three angles ...two or three out of the six is usually enough.

There are three ways to find if two triangles are similar: AA, SAS and SSS:

A community college enrolled 96,000 students in 2007, and the enrollment has increased by 7% every year since then. Graph the exponential function, y, that gives the number of students enrolled in terms of t, where t is the number of years since 2007.-The graph of the function begins at y = 96,000.
-The graph of the function does not have any asymptotes.
-The graph of the function shows the exponential growth.
-As t increases in the exponential function, the value of y approaches zero.

Answers

The formula of the function would be:
y = 96000(1.07)^t

The graph is an exponential function with y-intercept of 9600. The curve goes upward indefinitely as the value of time increases.

Therefore, from the choices, the statements that apply to the graph are:
-The graph of the function begins at y = 96,000.
-The graph of the function shows the exponential growth.
