user100 [1]

Answer:

Part (A) The required volume of the column is $s^2h$ .

Part (B) The volume be $s^2h=\frac{s^2h}{2}+\frac{s^2h}{2}$ .

Step-by-step explanation:

Consider the provided information.

It is given that the we have a square with side length "s" lies in a plane perpendicular to a line L.

Also One vertex of the square lies on L.

Part (A)

Suppose there is a square piece of a paper which is attached with a wire through one corner. As you blow it up it spins around on the wire.

This square moves a distance h along L, and generate a corkscrew-like column with square.

The cross section will remain the same.

So the cross section area of original column and the cross section area of twisted column at each point will be the same.

The volume of the column is the area of square times the height.

This can be written as:

$s^2h$

Hence, the required volume of the column is $s^2h$ .

Part (B) What will the volume be if the square turns twice instead of once?

If the square turns twice instead of once then the volume will remains the same but divide the volume into two equal part.

$s^2h=\frac{s^2h}{2}+\frac{s^2h}{2}$

Hence, the volume be $s^2h=\frac{s^2h}{2}+\frac{s^2h}{2}$ .

Line perpendicular to the line that goes through (0,0) and (3,2)

KonstantinChe [14]

Since the first line passes thru the origin, you can read off its slope from the coordinates of the other point (3,2): the slope is m = 2/3.

A line perpendicular to the first has slope -3/2, the negative reciprocal of 2/3.

Thus, the perpendicular line is y = (-3/2)x + b. Subbing 0 for y and 0 for x, we get b = 0. Therefore, the equation of this new line is y = (-3/2)x.

Answer:

m=9/8

Step-by-step explanation:

64m^2 -5=76

64m^2 =76+5

64m^2=81

m^2=81/64

m= $\sqrt{81/64}$

m=9/8

NO LINKS!! PART 2: Find the EXACT area and Circumference of each circle

Tema [17]

Answer:

2. center: (2, 5); radius: 3; Area: 9π; Circumference: 6π

4. center: (0, 0); radius: 8; Area: 64π; Circumference: 16π

Step-by-step explanation:

The standard form equation for a circle is ...

(x -h)² +(y -k)² = r² . . . . . . center (h, k), radius r

The value of r is used in the formulas for area (A) and circumference (C):

A = πr²

C = 2πr

Comparing the given equation to the standard form, we see ...

(x -h)² +(y -k)² = r²

(x -2)² +(y -5)² = 9

(h, k) = (2, 5) . . . . center

r² = 9

This tells us ...

r = √9 = 3 . . . . radius

The Area formula uses r² directly:

Area = πr² = π(9)

Area = 9π

The Circumference formula uses r:

Circumference = 2π(3)

Circumference = 6π

Comparing the given equation to the standard form, we find ...

(h, k) = (0, 0) . . . . center

r² = 64 ⇒ r = √64 = 8 . . . . radius

Area = 64π

Circumference = 2π(8) = 16π
