X²-3x=0
Solve by factoring
I know that x=0,3, but how do you get that from x(x-3)=0?

Answers

Answer 1
Answer: by equating each factor by 0
x*(x-3)=0
so, x=0 & x-3=0
x=0 & x=3
Answer 2
Answer: You have to solve the equation by essentially taking out the parentheses. So you will take x, which is outside the parentheses and multiply it by each factor inside of them.


So you will multiply x with x (first term in brackets) and multiply x with 3, second term in the bracket. You will then add these two terms together.

x^2 - 3x

Tiffany pays $40 for 160 minutes of talk time on her cell phone. How many minutes of talk time does she get per dollar?

Answers

If she pays 40 dollars then you have to divide that into how many minute she gets for that amount so you would have to divide 160 by 40 to get the minutes per dollar.
do 40 dovided by 160 & 160 divided by 40 and see which one makes more sense

Point P was rotated by 120(the center of rotation is indicated)​

Answers

After rotating point P by 120 degrees around the indicated center of rotation, the new position of point P can be calculated using trigonometric principles and the fraction of a full rotation it has undergone, resulting in its new coordinates.

To find the new position of point P, we can use the following steps:

Draw a line segment from the center of rotation to point P.

Measure the angle between the initial position of the line segment and the final position after the rotation. In this case, the angle is 120 degrees.

Divide the angle of rotation by the number of equal parts in a full circle (360 degrees). This will give us the fraction of a full rotation that the point has undergone. In this case,

120/360 = 1/3 of a full rotation.

Using trigonometric functions (sine and cosine), calculate the new coordinates of point P based on its distance from the center of rotation and the fraction of the circle it has rotated through.

What is the volume of the cylinder below? A. 72π units³

B. 36π units³

C. 45π units³

D. 90π units³

Answers

Answer:


Step-by-step explanation:

According to the diagram, the radius of this cyl. is 3 and the height is 4 (not 5).  The formula for the volume of a cylinder is:

V = pi*r^2*h.

Here, that volume is V = pi*3^2*4, or 36 pi cubic units.  That's Answer B.

The volume of the right cylinder is \boxed{36\pi {\text{ unit}}{{\text{s}}^3}}.

Further explanation:

The formula for the volume of the cylinder can be expressed as,

\boxed{{\text{Volume}} = \pi {r^2}h}

Here, ‘r” represents the radius of the cylinder and “h” represents the height of the cylinder.

Given:

The radius of the cylinder is {\text{3 units}} and the height of the cylinder is {\text{4 units}} and the slant height is 5{\text{ units}}

The options of the volume are given as follows.

A. {\text{72}}\pi {\text{uni}}{{\text{t}}^3}

B. 36\pi {\text{uni}}{{\text{t}}^3}

C. 45\pi {\text{uni}}{{\text{t}}^3}

D. 90\pi {\text{uni}}{{\text{t}}^3}

Explanation:

The volume of the right cylinder can be obtained as follows,

\begin{aligned}{\text{Volume}} &= \pi {r^2}h\n&= \pi* {\left( 3 \right)^2} * 4\n&= \pi * 9 * 4\n&= 36\pi\n\end{aligned}

The volume of the cylinder is 36\pi {\text{ unit}}{{\text{s}}^3}.

Option A is not correct.

Option B is correct.

Option C is not correct.

Option D is not correct.

Hence, the volume of the right cylinder is \boxed{36\pi {\text{ unit}}{{\text{s}}^3}}.
