How to find arc measurements

1 answer:

7 0

Finding an arc length requires knowing a bit about the geometry of a circle. Since the arc is a portion of the circumference, if you know what portion of 360 degrees the arc’s central angle is, you can easily find the length of the arc.

Answer:

Slope AB = -3/2

R = (4, -7)

Step-by-step explanation:

AB (-6 , 8) and (-2 , 2)

Slope AB = (8 - 2) /(-6 + 2) = 6/-4 = -3/2

Triangle QRS , QR is half of AB, same orientation and given Q (2 , -4) so R = (4, -7)

You need to buy a new cover for a pool.The pool is in shape of a trapezoid.The cost of the cover is .79.What is the total cost

jek_recluse [69]

Since we don't have the measurements for the trapezoid, we can't find the exact cost. However, I can explain how to solve the problem.

First, you need to find the the total area of the pool cover. Since it is in the shape of a trapezoid, use the formula below.

A = 0.5(h)(the sum of the bases)

Once you have the area, multiply by 0.79 and you will have the cost.

11.3 - p divided 2.8=1.5

raketka [301]

$11.3-\frac{p}{2.8}=1.5$

First you subtract by eleven point three (11.3) from both sides of equation form.

And it gave us ⇒ $11.3-\frac{p}{2.8}-11.3=1.5-11.3$ .

Then you simplify by equation.

And it gave us ⇒ $-\frac{p}{2.8}=-9.8$ .

Next, you multiply by two decimal eight (2.8) from both sides of equation form.

And it gave us ⇒ $2.8(-\frac{p}{2.8)}=2.8(-9.8)$ .

And then simplify by equation.

$-p=-27.44$ .

Next, you divide by negative one (-1) from both sides of equation form.

And it gave us, $\frac{-p}{-1}=\frac{-27.44}{-1}$ .

And finally simplify by equation form.

And it gave us the final answer is p=27.44.

Hope this helps!

Select the TRUE statement for completely random design.

Marysya12 [62]

Answer:

d.)The experimental units are assigned randomly to exactly one control group and one or more treatment groups

Step-by-step explanation:

Completely randomized design can be regarded as a type of experimental design in which the experimental units are assigned randomly for different treatments. This experimental design is utilized in cases whereby experimental units are seen to be “uniform" this implies that no uncontrolled factor in the experiment. completely randomized designs are engaged in studying effects of one primary factor by ignoring other nuisance variables it perform comparison of values of a response variable taking into account of the different levels of that primary factor. It should be noted that in completely random design, the experimental units are assigned randomly to exactly one control group and one or more treatment groups
