Hello, I can help.

The value of N- 7

Here is how i got the answer.

1: Multiply both sides by 2

2: Simplify 64*2 to 128

3: convert both sides; 2^n =2^7

4:divide 2 on both sides; n=7

Hope this helps.

The volume of a cone varies jointly with the area of the base and the height. when the area of the base is

strojnjashka [21]

The volume of a cone varies jointly with the area of the base and the height of the cone.

$V = kAh$

where
V = volume
k = constant of proportionality
A = area of the base
h = height of the cone

The given info is for A = 27, and h = 6, then V = 54 (all using appropriate units for area, length, and volume, respectively.)

Now we can find k, the constant of proportionality.

V = kAh

54 = k * 27 * 6

k = 54/(27 * 6)

k = 1/3

The formula is

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

Now we use the second set of info, the height and the volume, and we find the area of the base.

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

$124 = \dfrac{1}{3} \times A \times 12$

$124 = 4A$

$A = 31$

Answer: the area of the base is 31 cm^2

Find the distance between the parallel lines m and n whose equations are

MA_775_DIABLO [31]

Answer:Find the distance between the parallel lines m and n whose equations are y = x + 4 and y = x - 6, respectively.

There are several ways to do this...here's one

Let (0, 4) be a point on the first line

Then.......a line with a negative reciprocal slope going through this point will have the equation :

y = -x + 4........so......we can find the intersection of this line with y = x - 6....set both equations equal

-x + 4 = x - 6 add x, 6 to both sides

10 = 2x divide both sides by 2

5 = x

So...using -x + 4, the y value at intersection = -1.......

So...we just need to find the distance from (0,4) to ( 5, -1) =

√[ (5)^2 + (4 + 1)^2 ] = 5√2 ≈ 7.07 units

Here's a pic....AB is the distance with A = (0,4) and B = (5, -1)
