Check the picture below.

now, if AC is that much, recall, BD is the midsegment, thus AB = BC, so AB is just one of the equal halves of AC, so, AB is AC/2.

The radius of a circle is 4 inches. What is the circle's circumference?

mojhsa [17]

Answer:

8π inches or approximately 25.12 inches

Step-by-step explanation:

What's the circumference of a circle?

❖ The circumference of a circle is the distance around a circle.

How do we find the circumference of a circle?

❖ The formula to find the circumference of a circle is 2πr, where r =

radius. We can solve in terms of pi, or approximate pi to 3.14

Solving

$\pi * 4*2$
$\pi *8$
8π inches

or

$3.14*4*2$
$3.14*8$
25.12 inches

I’m not sure if I’m correct but a. Find the slope of the line b. state a point on the line

Agata [3.3K]

the equation of a line in point-slope form is

y - b = m(x - a)

where m is the slope and (a, b ) is a point on the line

y + 1 = $\frac{3}{5}$ (x + 5) is in this form

(a) with slope = $\frac{3}{5}$

(b) point on the line = (- 5, - 1 ) = (a, b)

A top-loading washing machine has a cylindrical basket that rotates about a vertical axis. The basket of one such machine starts

damaskus [11]

Answer:

$n_{tot}=44rev$

Step-by-step explanation:

In order to solve this problem we can make use of the following formula:

$\theta=(\frac{\omega_{f}+\omega_{0}}{2})t$

where θ is the total angle the basket has turned, ω is the angular velocity and t is the time.

Generally theta is written in radians and omega is written in radians per second. Now, since the revolutions are directly related to the radians and they want us to write our answer in revolutions, we can directly use the provided speeds in the formula, so we can rewrite it as:

$n=(\frac{f_{f}+f_{0}}{2})t$

where n represents the number of revolutions and f is the frequency at which the basket is turning.

The movement of the cylindrial basket can be split in two stages, when it accelerates and when it decelerates. So let's analye the first stage:

$n=(\frac{4rev/s+0}{2})(9s)=18rev$

and now let's analyze the second stage, where it decelerates, so we get:

$n=(\frac{0rev/s+4rev/s}{2})(13s)=26rev$

So now that we know how many revolutions the cylindrical basket will take as it accelerates and as it decelerates we can add them to get:

n=18rev+26rev=44rev

So the basket will turn a total of 44 revolutions during this 22s interval.

Find the perimeter of the following shapes.

DerKrebs [107]

Answer:

4. (a) = 12 m

(b) = 27 cm

(d) = 18 km

(e) = 10 m

(f) = 36 cm

Step-by-step explanation:

Perimeter is sum the distance round a figure.

if a shape has those, they signify that the shape has two side that are equal

a) 4 + 4 + 2 + 2 = 12. The top part is equal to the bottom part signified by those two lines. And the left is equal to the right .

b) 10 + 10 + 7 = 27

c) 5 + 5 + 8 + 6 = 24

d) 3 + 3 + 6 + 6 = 18

e) 2.5 + 2.5 + 2.5 + 2.5 = 10

f) 12 + 7 + 7 + 5 + 5 = 36

If you need any clarification or more explanation pls do mention in the comment section. i would like to help more.

Hope this helps and if it does pls mark as branliest answer thx.
