Help? I'm not exactly sure how to do this :/

uranmaximum [27]

What you do is plug the z value (first column) into the formula (second column), and solve for y. For instance, the first one would be y = -1-2, or -3. The x would be the x in the ordered pair, and the final ordered pair would be (-1,-3). Make sense?

For which survey is a sample not necessary?

BARSIC [14]

Answer:

<h2>How many car accidents involve airbag malfunctions?</h2><h2 />

This is because there's no need to survey an entire population for accurate results.

The other 3, regarding Colorado residents, middle school students, and classmates are considered a population.

For testing the amount of car accidents, a population is not needed.

3 of 8<br> The area of a circle is 16.71cm2.<br> Find the length of the radius rounded to 2 DP.

Cerrena [4.2K]

Answer:

Radius = 2.31 cm

Step-by-step explanation:

Area of circle = 16.71 square centimeters

$\pi r^2 = 16.71 \\3.14r^2=16.71\\r^2=\frac{16.71}{3.14}\\r^2=5.32\\\sqrt{r^2}=\sqrt{5.32}\\r=2.306$

Radius of circle = 2.31 centimeter

Find m∠A given ΔABC where a=4, b=6, c=3.

igomit [66]

For this question, we're going to use the law of cosines.
The law of cosines is the following equation:

$a^2=b^2+c^2-2(b)(c) \cos(A)$

We know the values of a, b, and c. We want to find the measure of angle A.
$a=4$
$b=6$
$c=3$

Now, plug in these values into the equation.

$4^2=6^2+3^2-2(3)(6) \cos(A)$
$16=45-36 \cos(A)$

Add both sides by $36 \cos(A)$ and subtract both sides by 16

$36 \cos(A)=29$

Divide both sides by 36

$\cos(A)= \dfrac{29}{36}$

Take the inverse cosine, or arc cosine, of both sides.
Using a calculator, you'll get the following result.

$A \approx 36.3^O$

The measure of angle A should be 36.3 degrees. Hope this helps! :)
