A small square cloth has an area of 361 cm2. Sarah sewed four of them together to form a larger square cloth. What is the perime

nika2105 [10]

Answer:

152 cm

Step-by-step explanation:

Once again its a square. All sides are equal.

Square root 361 to get 19.

19 x 19 = 361

4 was sewed together.

You could either add, 361+361+361+361

Or you could multiply, 361 x 4

Either way you get 1444.

You could either square root 1444 to get the side length or you could add the previous side length to itself once to get the new side length of 38.

Now you need to get perimeter.

P=4 x length

P=4 x 38

For what values of theta (0 less than or equal to theta less than or equal to 2pi) do maximum r values occur on the graph the po

9966 [12]

Answer:

Step-by-step explanation:

To find the values of the angle which makes maximum r you use the derivative of r

$\frac{dr}{d\theta}=\frac{1}{3}sin(3\theta)$

If you equals this derivative to zero you obtain the value of the angle:

$\frac{dr}{d\theta}=0\\\\cos3\theta=0\\\\3\theta=\frac{\pi}{2}\\\\\theta=\frac{\pi}{6}$

However, the values of 5π/6 and 9π/6 are also available, because makes the sinusoidal function equal to 1.

hence, the answer is:

$\theta_1=\frac{\pi}{6} \\\\\theta_2=\frac{5\pi}{6}\\\\\theta_3=\frac{9\pi}{6}=\frac{3\pi}{2}$

Use special right triangles to solve for the exact value of x. 4 9 16

Gelneren [198K]

Answer: A basic theorem for finding the third length of a right angle triangle is the Pythagoras Theorem.

In a right angle triangle, the slant and usually longest side is called the Hypotenuse while the other two sides are Opposite and Adjacent.

The Pythagoras Theorem States:

$hypotenuse^{2} = opposite ^{2} + adjacent ^{2}$

Step-by-step explanation:

If for example, we are given the other two sides as 3 and 4 respectively,

Using

$Hyp^2=Opp^2+Adj^2$

$Hyp^2 =3^2+4^2=25$

Hypotenuse = $\sqrt{25}$ =5

These set of numbers (3,4,5) in this that satisfies the theorem are called Pythagorean Triples

I need first one and the second one please! I need it tomorrow!

ArbitrLikvidat [17]

I have a total of 11 pencils = total outcome
a- since we have 6 Red, P(Red)=6/11
b- P(Black) = 3/11
c- P(Green) = 1/11
For the dice:
Total outcome 6 so :
P(3) =1/6
P(1) =1/6
P(less than5) means P( of 1 OR 2 OR 3 Or 4)
Since we have "OR" it means we can add the P(probabilities)====>
P( of 1 OR 2 OR 3 Or 4)=1/6+1/6+1/6+1/6=
= 4/6 = 2/3
