The answer would be A/2(pi)r - (minus) 2(pi)r^2

The answer would be ("A" divided by 2 times pi times r ) minus 2 times pi times r squared.

<h2>SOLVING</h2>

$\Large\maltese\underline{\textsf{A. What is Asked}}$

What's the equation with a slope of -4 that goes through (-1,1)? find it

$\Large\maltese\underline{\textsf{B. This problem has been solved!}}$

The equation used, here is $\bf{y-y1=m(x-x1)}$ .

$\bf{y-1=-4(x-(-1)}$ | simplify after putting in the information given

$\bf{y-1=-4(x+1)}$

$\rule{300}{1.7}$

$\bf{Result:}$

$\bf{=y-1=-4(x+1)}$

$\boxed{\bf{aesthetic\not101}}$

What is 720° converted to radians? <br> a) 1/4<br> b) pi/4<br> c) 4/pi<br> d) 4pi

baherus [9]

4π radians

<h3>Further explanation</h3>

We provide an angle of 720° that will be instantly converted to radians.

Recognize these:

$\boxed{ \ 1 \ revolution = 360 \ degrees = 2 \pi \ radians \ }$
$\boxed{ \ 0.5 \ revolutions = 180 \ degrees = \pi \ radians \ }$

From the conversion previous we can produce the formula as follows:

$\boxed{\boxed{ \ Radians = degrees \times \bigg( \frac{\pi }{180^0} \bigg) \ }}$
$\boxed{\boxed{ \ Degrees = radians \times \bigg( \frac{180^0}{\pi } \bigg) \ }}$

We can state the following:

Degrees to radians, multiply by $\frac{\pi }{180^0}$
Radians to degrees, multiply by $\frac{180^0}{\pi }$

Given α = 720°. Let us convert this degree to radians.

$\boxed{ \ \alpha = 720^0 \times \frac{\pi }{180^0} \ }$

720° and 180° crossed out. They can be divided by 180°.

$\boxed{ \ \alpha = 4 \times \pi \ }$

Hence, $\boxed{\boxed{ \ 720^0 = 4 \pi \ radians \ }}$

<u>Another example:</u>

Convert $\boxed{ \ \frac{4}{3} \pi \ radians \ }$ to degrees.

$\alpha = \frac{4}{3} \pi \ radians \rightarrow \alpha = \frac{4}{3} \pi \times \frac{180^0}{\pi }$

180° and 3 crossed out. Likewise with π.

Thus, $\boxed{\boxed{ \ \frac{4}{3} \pi \ radians = 240^0 \ }}$

The additional set of values which could be included in the table is; (10,2).

<h3>Which additional set of values can be included in the table?</h3>

As evident in the task content, it follows that for a 15 unit increase in x, depth, there is a 3 unit increase in y, pressure.

On this note, it follows that with each 5 unit increase in x corresponds to 1 unit increase in y.

And ultimately, at x = 10, y = 2 × 1 = 2.

Sue and Javier are working on a statistics project to estimate the proportion of students at their school who have a pet dog. Su

egoroff_w [7]

Answer:

the width of sue's interval will be narrower than javier's.

Step-by-step explanation:

in this problem, i do believe that sue's interval will be more narrow. in the formula,

p-hat ± $\sqrt{phat(1-phat)/ n$ ,

a larger "n" value will lead to a smaller standard error. given that the population proportion is the same for both, and the sample size is the only difference, the standard error of sue's interval will be smaller than javier's, therefore making her whole confidence interval smaller.

again, i do believe this is correct, this is what i have in my AP stat notes. hope this helps!
