The angular velocity of a point with radius 8 feet is 10 pi radians per second. Find the speed of the point.0.8pi ft/sec
1.25pi ft/sec
80pi ft/sec

Answers

Answer 1

Answer:

Answer:

80π feet/ second.

Step-by-step explanation:

Angular velocity of a point = 10π radians per second

Radius of the circle is 8 feet.

We know the formula of angular velocity is

Angular velocity = $(speed)/(radius)$

10π = $(speed)/(8)$

Speed = 80π feet/ second.

Option C is the answer.

Answer 2

Answer:

Answer: $80\pi\text{ ft/sec}$

Step-by-step explanation:

Formula : $\text{Speed= Angular velocity x Radius}$ (1)

We are given that , The angular velocity of a point with radius 8 feet is 10 pi radians per second.

i.e. Radius = 8 feet

Angular velocity = $10\pi$ radians per second.

Then, the speed of the point will be :-

$\text{Speed= }10\pi * 8$ [using (1)]

$=80\pi\text{ ft/sec}$

Hence, the speed of the point $=80\pi\text{ ft/sec}$

If m∠A=(3x)∘and m∠D=(x+60)∘,what value of xmakes ABCD a parallelogram?

Enter the correct value of x.

Answers

Answer:

Step-by-step explanation:

Adjacent angles of a parallelogram add up to 180 degrees, meaning that (3x)+(x+60)=180 degrees. You can use this to set up the following equation:

3x+x+60=180

4x=120

x=30 degrees. Hope this helps!

Final answer:

In a parallelogram, opposite angles are equal. Therefore, set 3x (angle A) equal to x + 60 (angle D). Solving for x, we get x = 30.

Explanation:

In this case, we're working with a parallelogram, and one of the properties of a parallelogram is that its opposite angles are equal. That means that ∠A is equal to ∠D. So we set (3x) equal to (x + 60).

To determine the value of x, we can solve this equation:
3x = x + 60. Subtract x from both sides to get 2x = 60, then divide by 2 to get x = 30.

So, the value of x that makes ABCD a parallelogram is 30.

Answer:

Step-by-step explanation:

x=138x

Answer:

the value of x in the equation 8x + 13 = 26 is 1.625.

Step-by-step explanation:

I'm sorry, but that is not the correct method to solve the equation 8x + 13 = 26.

To solve for x, you need to isolate the variable on one side of the equation. Here's the correct way to solve it:

8x + 13 = 26

First, subtract 13 from both sides of the equation:

8x = 26 - 13

8x = 13

Then, divide both sides of the equation by 8 to solve for x:

x = 13/8

x = 1.625
