Answer:

$\: \sqrt{81 } = 9$

Step-by-step explanation:

$\sqrt{81 } = \sqrt{3 \times 3 \times 3 \times 3} \\ = 3 \times 3 \\ =9$

You have to prime factorise 81 and then you will get <u>9</u> as the answer.

MATH QUESTION : WORTH 45 PTS

trapecia [35]

y ≤ x − 5

y ≥ −x − 4

This is a check and see type of problem.

if x=5

y ≤ 5 − 5 y≤ 0

y ≥ −5 − 4 y ≥-9

-9≤ y ≤ 0

-2 works so (5,-2) is a solution

if x= -5

y ≤ -5 − 5 y≤ -10

y ≥ 5 − 4 y ≥1

no solution

Choice B (5,-2)

Find the measure of arc DF in degrees, given that the shaded region has an area of 45.27 square centimeters. If necessary, round

marishachu [46]

$\bf \textit{area of a sector of a circle}\\\\
A=\cfrac{\theta \pi r^2}{360}\qquad 
\begin{cases}
r=radius\\
\theta =angle\ in\\
\qquad degrees\\
----------\\
r=6\\
A=45.27
\end{cases}\implies 45.27=\cfrac{\theta\pi \cdot 6^2}{360}
\\\\\\
45.27\cdot 360=\theta \pi 6^2\implies \cfrac{45.27\cdot 360}{36\pi }=\theta
\\\\\\
144.09888547540\approx\theta \implies 144.10^o\approx\theta =\widehat{DF}
\\\\\\
\textit{now, that gives you the central angle, however}\qquad \theta =\widehat{DF}$

bearing in mind that, arcs get their angle measurement from the central angle they're in. Thus, the measure of that central angle, is the same measure in degrees of that arcDF.

These triangles are similar which similarity statement is correct

PolarNik [594]

As we can see from the figure

Angle A corresponds to Angle F

Angle B corresponds to Angle E

Angle C corresponds to Angle D

So Triangle ABC is similar to triangle FED

So THIRD option is the correct one
