Which equation represents a circle that contains the point (-5, -3) and has a center at (-2, 1)?

oksian1 [2.3K]

Answer:

(x+1)2+(y−2)2=5

Explanation:

The general form for a circle with center

(a,b) and radius r is XXX(x−a)2+(y−b)2=r2

With center (−1,2) and given that (0,0) is a solution (i.e. a point on the circle),according to the Pythagorean Theorem: XXX r 2=(−1−0)2+(2−0)2=5

and since the center is (a,b)=(−1,2)by applying the general formula we get:XXX(x+1)+(y−2)2=5

Two buildings on opposites sides of a highway are 3x^3- x^2 + 7x +100 feet apart. One building is 2x^2 + 7x feet from the highwa

Furkat [3]

Given:

Distance between two buildings = $3x^3- x^2 + 7x +100$ feet apart.

Distance between highway and one building = $2x^2 + 7x$ feet.

Distance between highway and second building = $x^3 + 2x^2 - 18$ feet.

To find:

The standard form of the polynomial representing the width of the highway between the two building.

Solution:

We know that,

Width of the highway = Distance between two buildings - Distance of both buildings from highway.

Using the above formula, we get the polynomial for width (W) of the highway.

$W=3x^3- x^2 + 7x +100-(2x^2 + 7x)-(x^3 + 2x^2 - 18)$

$W=3x^3- x^2 + 7x +100-2x^2-7x-x^3 -2x^2+18$

Combining like terms, we get

$W=(3x^3-x^3)+(- x^2 -2x^2-2x^2)+ (7x -7x)+(100 +18)$

$W=2x^3-5x^2+0+118$

$W=2x^3-5x^2+118$

Therefore, the width point highway is $2x^3-5x^2+118$ .

Can someone help me with Volume pyramids..

Minchanka [31]

Answer:

$\large\boxed{V=\dfrac{125}{3}\ cm^3=41\dfrac{2}{3}\ cm^3}$

Step-by-step explanation:

The formula of a volume of a pyramid:

$V=\dfrac{1}{3}BH$

B - area of a base

H - height

We have

$B=5\cdot5=25\ cm^2$

$H=5\ cm$

Substitute:

$V=\dfrac{1}{3}(25)(5)=\dfrac{125}{3}=41\dfrac{2}{3}\ cm^3$
