Mark needed to buy some items for a science project. The items were priced $3.25, $0.55, $2.95, and $4.25 before tax. If everyth

ing in the store was on sale for 20% off, what was the total cost of the items he bought, before tax?

The total cost was $8.80 before tax.

Step-by-step explanation:

The prices of items;

$3.25, $0.55, $2.95, and $4.25

Total price = Sum of all prices

Total price = $3.25 + $0.55 + $2.95 + $4.25

Total price = $11.00

Sale = 20% off

Discount = 20% of total price

Discount = $\frac{20}{100}*11$

Discount = $\frac{220}{100}= \$2.20$

Total cost of items bought = Total price - Discount

Total cost of items bought = 11.00 - 2.20 = $8.80

The total cost was $8.80 before tax.

What is the center of a circle whose equation is x2 + y2 + 4x – 8y + 11 = 0?

Valentin [98]

Answer:

Step-by-step explanation:

eq. of circle is x²+y²+2gx+2fy+c=0

center=(-g,-k)

given eq. is x²+y²+4x-8y+11=0

comparing

2gx=4x

g=2

2fy=-8y

f=-4

center=(-2,4)

A 10 meter piece of wire is cut in to two pieces. One piece is 2 meters longer than the other. How long are the pieces?

Vilka [71]

Answer:

Step-by-step explanation:

total metre = 10m

If one piece is 4m then 2m more then that = 4 + 2 = 6m

So total = 4 + 6 = 10m

find a curve that passes through the point (1,-2 ) and has an arc length on the interval 2 6 given by 1 144 x^-6

taurus [48]

Answer:

$f(x) = \frac{6}{x^2} -8$ or $f(x) = -\frac{6}{x^2} + 4$

Step-by-step explanation:

Given

$(x,y) = (1,-2)$ --- Point

$\int\limits^6_2 {(1 + 144x^{-6})} \, dx$

The arc length of a function on interval [a,b]: $\int\limits^b_a {(1 + f'(x^2))} \, dx$

By comparison:

$f'(x)^2 = 144x^{-6}$

$f'(x)^2 = \frac{144}{x^6}$

Take square root of both sides

$f'(x) =\± \sqrt{\frac{144}{x^6}}$

$f'(x) = \±\frac{12}{x^3}$

Split:

$f'(x) = \frac{12}{x^3}$ or $f'(x) = -\frac{12}{x^3}$

To solve fo f(x), we make use of:

$f(x) = \int {f'(x) } \, dx$

For: $f'(x) = \frac{12}{x^3}$

$f(x) = \int {\frac{12}{x^3} } \, dx$

Integrate:

$f(x) = \frac{12}{2x^2} + c$

$f(x) = \frac{6}{x^2} + c$

We understand that it passes through $(x,y) = (1,-2)$ .

So, we have:

$-2 = \frac{6}{1^2} + c$

$-2 = \frac{6}{1} + c$

$-2 = 6 + c$

Make c the subject

$c = -2-6$

$c = -8$

$f(x) = \frac{6}{x^2} + c$ becomes

$f(x) = \frac{6}{x^2} -8$

For: $f'(x) = -\frac{12}{x^3}$

$f(x) = \int {-\frac{12}{x^3} } \, dx$

Integrate:

$f(x) = -\frac{12}{2x^2} + c$

$f(x) = -\frac{6}{x^2} + c$

We understand that it passes through $(x,y) = (1,-2)$ .

So, we have:

$-2 = -\frac{6}{1^2} + c$

$-2 = -\frac{6}{1} + c$

$-2 = -6 + c$

Make c the subject

$c = -2+6$

$c = 4$

$f(x) = -\frac{6}{x^2} + c$ becomes

$f(x) = -\frac{6}{x^2} + 4$
