The diameter of a circle has end points j(12,4) and k(-4,8)

Mathematics
1 answer:
alexdok [17]3 years ago
4 0

Answer:

diameter = 4√17;

radius = 2√17; and

center:  (4,6)

Step-by-step explanation:

The end points J (12,4) and K(-4,8) define the diameter of a circle, as well as the radius and center.  

Using the distance formula to find the diameter, d, we get:

d = √ ( (12+4)^2 + (4-8)^2 ) = √ ( 256 + 16 ), or √272 = √(8)(34)

                                         =  √(17)(2^4)) = 4√17

and the radius is half that, or 2√17.  The coordinates of the center can be found using the midpoint rule:  ( [12-4]/2, [4+8]/2 ), or (4, 6).

A french fry stand at the fair serves their fries in paper cones. The cones have a radius of 22 inches and a height of 66 inches
icang [17]

Answer:

The height of the new cones will be 16.5 inches.

Step-by-step explanation:

We know that,

The volume of a cone is,

V=\frac{1}{3}\pi r^2 h

Where, r is the radius of the cone,

h is the height of the cone,

In the original cone,

r = 22 inches,

h = 66 inches,

Thus, the volume would be,

V_1=\frac{1}{3}\pi (22)^2(66)

Also, for the new cone,

r = 44 inches,

Let H be the height,

So, the volume of the new cone would be,

V_2=\frac{1}{3}\pi (44)^2(H)

According to the question,

V_2=V_1

\implies \frac{1}{3}\pi (44)^2(H)=\frac{1}{3}\pi (22)^2(66)

\implies H=\frac{22^2(66)}{44^2}=(\frac{22}{44})^2\times 66 = \frac{66}{4}=16.5

Hence, the height of the new cones will be 16.5 inches.

V=1/3(7 x 6)6<br> math equation just solve pls and thanks
seropon [69]

Answer:

V=84

Step-by-step explanation:

1. 7*6=42. make 42 a fraction by making it 42/1.

2. 1/3*42/1=42/3

3. make 6 a fraction by making it 6/1

4. 42/3*6/1=252/3

5. 252/3=84

Which expression represents the number 5i4+2i3+8i2+−4  rewritten in a+bi  form?
aniked [119]
Remember
i²=-1 so
i³=-i
i⁴=1

so
5i⁴+2i³+8i²-4
5(1)+2(-i)+8(-1)-4
5-2i-8-4
-7-2i is the form
