The cancellation property sin−1(sin(x)) = x is valid for x in what interval
pochemuha

Answer:

It is given that : Sin^{-1}(Sin (x) =x

As we have to find the Domain of Sin^{-1}(Sin (x).

-1 ≤ sin x ≤1

Sin^{-1}(-1)\leq Sin^{-1}(Sin x)\leq Sin^{-1}(1)\\\frac{-\pi}{2}\leq x\leq \frac{\pi }{2}

So it is defined for x lying between (\frac{-\pi}{2}, \frac{\pi }{2}) .

As meaning of Domain is those values of x for which any function f(x) is defined.

A regulat pentagon has side lenghts of 5.8cm and apothem of 4cm. calculate its perimeter and area​
Kryger [21]

PENTA = 5.

a regular polygon has all equal sides, so if one side is 5.8, all are, so the perimeter for this pentagon with 5 sides is 5.8 + 5.8 + 5.8 + 5.8 + 5.8 = 29.

\bf \textit{area of a regular polygon}\\\\ A=\cfrac{1}{2}ap~~ \begin{cases} p=perimeter\\ a=apothem\\ \cline{1-1} p=29\\ a=4 \end{cases}\implies A=\cfrac{1}{2}(4)(29)\implies A=58

Jenny peddled her bike 30 miles in 40 minutes. If she traveled at the same speed, how far would she travel in 3 hours?
mart [117]

Answer:

Jenny cycles the grand distance of 29 and one third of a mile.

Step-by-step explanation:

I want to answer this using fractions and without multiplying by an awkward recurring decimal.

Cycling 11 miles in 45 minutes and continuing at the same speed means she will go 22 miles in 90 minutes

To scale up 90 mins to the required 120 mins (2 hours) multiply by 4/3.

22 x (4/3) = 88/3

Jenny will travel 88/3 miles in 2 hours.

Not happy with top heavy fractions?

Let's round up 88/3 to 90/3 by adding 2/3.

90/3 = 30 and to get back to the answer we just take away the two thirds we added when rounding up.

Jenny cycles the grand distance of 29 and one third of a mile.

I think that is the correct answer.

A catalog of scientific equipment states that the lens of a particular telescope has a circumference of 6.28 yards. What is the
nexus9112 [7]

The area of lens is 3.14 square yards.

Step-by-step explanation:

Given,

Circumference of lens = 6.28 yards

Circumference = 2πr

6.28=2*3.14*r\\6.28=6.28r\\6.28r=6.28

Dividing both sides by 6.28

\frac{6.28r}{6.28}=\frac{6.28}{6.28}\\r=1

Area of lens = πr²

Area of lens = 3.14*(1)^2=3.14*1

Area of lens = 3.14 square yards

The area of lens is 3.14 square yards.

Keywords: area, circumference
