Answer:

-12 and -5

Step-by-step explanation:

a+b=-17

b-a=7

b=7+a

a+7+a=-17

2a+7=-17

2a=-17-7

2a=-24

a=-12

-12+b=-17

b=-17+12

b=-5

so a and b are -12 and -5 respectively

The estimated velocity v (in miles per hour) of a car at the end of a drag race is v=234\sqrt[3]{p/w} , where p is the horsepowe

Dennis_Churaev [7]

Answer:

299 miles per hour

Step-by-step explanation:

$v=\frac{234}{\sqrt[3]{\frac{p}{w}}}$

$v=\frac{234}{\sqrt[3]{\frac{1311}{2744}}}$

$v\approx299$

Therefore, the velocity of the car at the end of a drag race is 299 miles per hour

a small bridge sit atop for cube shaped powers that all have the same volume. The combined volume of the four pillars is 503 how

Natasha_Volkova [10]

Answer:

60 inches long are the sides of the pillars.

Step-by-step explanation:

Given : A small bridge sits atop four cube shaped pillars that all have the same volume. the combined volume of the four pillars is 500 ft cubed.

To find : How many inches long are the sides of the pillars?

Solution :

Refer the attached picture below for Clarence of question.

The volume of the cube is $V=a^3$

Where, a is the side.

The combined volume of the four pillars is 500 ft cubed.

The volume of each cube is given by,

$V=\frac{500}{4}=125\ ft^3$

Substitute in the formula to get the side,

$125=a^3$

$a=\sqrt[3]{125}$

$a=5\ ft$

We know, 1 feet = 12 inches

So, 5 feet = $5\times 12=60$ inches

Therefore, 60 inches long are the sides of the pillars.

What is the equation of the circle with center (0, 0) that passes through the point (–4, –6)?

Vadim26 [7]

If the center is in point P(a,b) and has a radius r then circle equation is:

(x-a)²+(y-b)²=r².

In your task we've got P(0,0) so the circle equation is x²+y²=r².

We have to find r. Radius start at (0,0) and end at (-4,-6) therefore

r=√((-4)²+(-6)²) and

r²=(-4)²+(-6)²=16+36=52.

So answer is x²+y²=52.
