Answer:

d = 6

Step-by-step explanation:

3(2d-8)=11d-18(d-3)

6d - 24 = 11d -18d +54

6d-11d+18d = 24+54

13d = 78

d = 6

Find the Area Of each circle.
Levart [38]

The area of the circle A and B is 86.54 inches and 124.62 mm

According to the statement

we have given that the radius of the circle A and b and we have to find the area of the given circle.

So, we know that the

The area enclosed by a circle of radius r is πr².

So, For area of the circle

For condition A :

diameter = 10.5 inches

then radius = 5.25

Area = πr²

Area = 3.14*27.56

Area = 86.54 inches

Now, For condition B :

radius = 6.3 mm

Area = πr²

Area = 3.14*39.69

Area = 124.62mm

So, The area of the circle A and B is 86.54 inches and 124.62 mm

What's the equation of the line perpendicular to y=-3/2x+4 through the point ( 2,-3)
Korvikt [17]
Because it's perpendicular, you know that they must have the same slope, -3/2. So, just factor that and the point into the slope-point form to get

y = -3/2x

Select the correct answer. A circle is described by the equation x2 + y2 + 14x + 2y + 14 = 0. What are the coordinates for the c
son4ous [18]

Answer:

The correct answer is D.

Step-by-step explanation:

Given:

General equation of second degree

x² + y² + 14 x + 2 y + 14 = 0

We must transform given equation to the canonical form from which we will read requested data.

The canonical form of the circle equation is:

(x - p)² + (y - q)² = r²  

Where p and q are the coordinates of the center of the circle and r are radius.    (p,q) = (x,y)

x² + 2 · x ·7 + 7² - 7² + y² + 2 · y · 1 + 1 - 1 + 14 = (x+7)² + (y+1) - 49 - 1 + 14 = 0

(x + 7)² + (y + 1)² = 36

We see that p = - 7 , q = - 1 and  r = 6

God with you!!!
