Answer:

The area of the square is 4 square cm. The area of the square and the length of its side are directional proportional quantities.

Step-by-step explanation:

A square has equal sides. We have to do length times height to get the area. 2*2 is 4. The area is 4 cm. And since this value needs to be multiplied by itself to get the area, it IS proportional.

What is the equation of a hyperbola with a = 5 and c = 15? Assume that the transverse axis is horizontal.
gogolik [260]

Answer:

\frac{x^2}{25} -\frac{y^2}{200} =1

Step-by-step explanation:

Recall that the equation of  hyperbola centered at the origin with transverse horizontal axis has the general form:

\frac{x^2}{a^2} -\frac{y^2}{b^2} =1\\and\,\,\,\, with\\c=\sqrt{a^2+b^2}

since we know that a = 5 ,and c = 15,we can solve for b:

15=\sqrt{5^2+b^2} \\15^2=25+b^2\\b^2=200\\

then the equation of the hyperbola becomes:

\frac{x^2}{5^2} -\frac{y^2}{200} =1\\\frac{x^2}{25} -\frac{y^2}{200} =1

Find the LCM of 13 and 52.
lesya692 [45]
The LCM is the smallest common multiple. To find this, list the multiples of each number

52: 52, 104, 156....
13: 13, 26, 39, 52.....

the smallest number that is a mutiple of both is 52.

so, the LCM of 13 and 52 is 52.

Hope this helps!

GIVE OUT BRAINLY 2) Kathleen is a sales associate in a jewelry store. She earns $560/wk plus an 8% commission on sales. How much
pashok25 [27]

Answer:

1750

Step-by-step explanation:

Earns per week: $560

Total sales per week: x

Weekly commission on sales: 0.08x

Total Earning per week: 560 + 0.08x

560 + 0.08x \geqslant 700

Simplifying this inequality:

560 + 0.08x \geqslant 700\\0.08x \geqslant 700 - 560\\0.08x \geqslant 140\\\\x \geqslant \frac{140}{0.08}\\\\x \geqslant 1750

Her sales must be at least $1750.
