Find the standard equation of the circle defined by the equation x^2 + y^2 +8x - 12y + 43 = 0. ANSWERS ATTACHED, due in 2 HOURS,

puteri [66]

Answer:

Solution: Option C

Step-by-step explanation:

Our goal here is to factor the expression such that it is converted into the circle equation (x - a)² + (y - b)² = r² where r = radius centered at point (a,b).

$x^2\:+\:y^2\:+8x\:-\:12y\:+\:43\:=\:0$ (Factor the expression "x² + 8x")

$x^2+8x = x\left(x+8\right)$ (Factor the expression "y² - 12y")

$\:y^2-12y =y\left(y-12\right)$

That leaves us with the expression $\left(x-\left(-4\right)\right)^2+\left(y-6\right)^2=3^2$ , or in other words $(x+4)^2 +(y-6)^2 = 9$ . As you can see our solution is option c.

The formula v=r2h gives the volume of a cylinder with a radius r and height h. Find the volume of cylinder with radius (x+4) cm

yawa3891 [41]

Answer:

The answer to your question is: V = 5x² + 40x + 80

Step-by-step explanation:

Formula = V = r²h

r = x + 4

h = 5

Substitution

V = (x + 4 )² 5

V = (x² + 8x + 16)5 expand

V= 5x² + 40x + 80 simplify

A quadrilateral is graphed in the coordinate plane below. Which classification best describes the quadrilateral (parallelogram,

Ahat [919]

Answer:

Trapezoid

Step-by-step explanation:

Given quadrilateral has vertices at points A(-2,-1), B(3,13), C(15,5) and D(13,-11).

Find slopes of lines AD and BC:

$\text{Slope}_{AD}=\dfrac{y_D-y_A}{x_D-x_A}=\dfrac{-11-(-1)}{13-(-2)}=\dfrac{-11+1}{13+2}=\dfrac{-10}{15}=-\dfrac{2}{3}\\ \\\text{Slope}_{BC}=\dfrac{y_C-y_B}{x_C-x_B}=\dfrac{5-13}{15-3}=\dfrac{-8}{12}=-\dfrac{2}{3}$

Since the slopes are the same, lines AD and BC are parallel.

Find slopes of lines ABD and CD:

$\text{Slope}_{AB}=\dfrac{y_B-y_A}{x_B-x_A}=\dfrac{13-(-1)}{3-(-2)}=\dfrac{14}{5}\\ \\\text{Slope}_{CD}=\dfrac{y_D-y_C}{x_D-x_C}=\dfrac{-11-5}{13-15}=\dfrac{-16}{-2}=8$

Since the slopes are different, lines AB and CD are not parallel.

This means quadrilateral ABCD is trapezoid (two opposite sides - parallel and two another opposite sides - not parallel)
