Which is the center of a circle whose equation is x2+y2+4x-8y+11=0?
Nikolay [14]

Answer:

Center (-2 , 4)

Step-by-step explanation:

x^2 + 4x + y^2 - 8y = - 11

(x^2 + 4x + (4/2)^2 + (y^2 - 8y + (8/2)^2 ) = - 11 + 4 + 16

(x + 2)^2 + (y -  4)^2 = 9

Center (-2,  4)

A cylinder has volume 78 cm3 . What is the volume of a cone with the same radius and height? A 26 cm3 B 39 cm3 C 156 cm3 D 234 c
otez555 [7]

Answer:

Option A - 26 \mathrm{cm}^{3}

Step-by-step explanation:

Given: The volume of a cylinder = 78 \mathrm{cm}^{3}

Let us substitute the volume of cylinder in the formula.

The formula for volume of a cone is V=\frac{\pi r^{2} h}{3}                    (1)

The formula for volume of a cylinder is V=\pi r^{2} h              (2)

Substituting V=78 in equation (2), we get,

\begin{array}{c}{V=\pi r^{2} h} \\{78=\pi r^{2} h}\end{array}

Given that the cone has the same radius and height of that of the cylinder, let us substitute 78=\pi r^{2} h in equation (1)

\begin{array}{l}{V=\frac{\pi r^{2} h}{3}} \\{V=\frac{78}{3}} \\{V=26}\end{array}

Thus, the volume of a cone with the same radius and height of a cylinder is 26 \mathrm{cm}^{3}.

In the diagram below, points A and B are 3 inches apart. Try to find two points that are 1 inch from point A
____ [38]

Answer:

It is impossible to find two points that are both 1 inch and 1.5 inches from the point A simultaneously as shown in the following proof

From segment addition postulate given a point C that is between the points of a segment AB, we have;

AC + CB = AB

Therefore, where AC = 1 inch and CB = 1.5 inches, we have;

AC + CB = 1 inch + 1.5 inches = 2.5 inches ≠ AB = 3 inches

However it is possible to find two points in which one of the points is 1 inch from the point A while the other point is 1.5 inches from the point B

The Bangor Coat Factory found that the number of coats sold N varies directly as their advertising budget A and inversely as the
asambeis [7]
<span>The answer is 25,200.
This can be solved by using proportion.
Set up the proportion as follows:
 (10,800/30,000)=(x)/(70,000)
By cross multiplying you get:
 (30,000)(x)=(70,000)(10,800)
               x=[(70,000)(10,800)]/30,000
               x=25,200 coats</span>
