Well the radian is the measure of the radius
this line measure is then ligned up to the circumference
mearuse of 1 raidan is always equal to the measure of the radius therfor the true statements are

ratio of arc legnth to r is always equal to 1

I'm not sure what 'if the measure of is'

but I think the answer is
if the measure of is 1 radis, than the arc legnth is r since r reaprensents radius

so first and third choice are correct

Can someone help me find the relative maximum and minimum? please i really need help
bearhunter [10]

9514 1404 393

Answer:

  • relative maximum: -4
  • relative (and absolute) minimum: -5

Step-by-step explanation:

The curve has a relative maximum where values on either side are lower. This looks like a peak in the curve. There is one of those on the y-axis at y = -4.

The relative maximum is -4.

__

A relative minimum is a low point, where the curve is higher on either side. There are two of these, located symmetrically about the y-axis. The minimum appears to be about y = -5. (They might be at x = ± 1, but it is hard to tell.)

The relative minima are -5.

__

A minimum or maximum is absolute if no part of the curve is lower or higher. Here, the minima are absolute, while the maximum is only relative. (The left and right branches of the curve go higher than y=-4.)

_____

Identifying the points on the curve should be the easy part. Deciding what the coordinates are can be harder when the graph is like this one.

66,681 rounded to the nearest ten thousand??
grandymaker [24]

Hey there! I'm happy to help!

This number is sixty six thousand six hundred eighty one. This means that our ten thousandths place is the first 6.

We look to the right place to see if it is 5 or bigger. It is also six.

Therefore we bump the ten thousands place up 1 to 7 and we make everything else 0, giving us 70,000.

Have a wonderful day! :D

Use the confidence interval to find the estimated margin of error. Then find the sample mean. A biologist reports a confidence i
mash [69]

Complete Question

A biologist reports a confidence interval of (3.5,4.9) when estimating the mean height (in centimeters) of a sample of seedlings. What is the estimated margin of error and the sample mean?

Answer:

The  margin of error is  E = 0.7

The  sample mean is  \=  x  =  4.2

Step-by-step explanation:

from the question we are told that

   The  upper limit is  k  =  4.9

    The  lower limit is  r = 3.5

Generally the margin of error is mathematically represented as

      E =  \frac{k - r}{ 2}

      E = \frac{ 4.9  -  3.5 }{2}

     E = 0.7

Generally the sample mean is mathematically evaluated as

        \=  x = k  -  E

=>    \= x  =  4.9 - 0.7

=>    \=  x  =  4.2

Find an equation of the line passing through the pair of points. Write the equation in slope-intercept form.
muminat

Answer:

y=10-x

Step-by-step explanation:

1. Find the slope of the equation using the formula (change in y/change in x)

(3-7)/(7-3)=-4/4=-1

2. Plug in the slope and one of the coordinate points to the slope-intercept form to find the y-intercept.

slope-intercept form: y=mx+b

7=-3+b

b=10

3. Put the slope-intercept form of the equation together.

y=10-x
