The Area of a circle =π.R² (R=radius). & π 3.14

Since you didn't give the length of the Radius, then the area of the circle=3.14R²

#4 - the region of a plane inside an angle

#5 - the region of a plane outside an angle

#6 - an angle with a measure of anything less than 90 degrees.

#7 - an angle with a measure of anything greater than 90 degrees.

These all should be right :)

Determine in which quadrant the product of 5(cos3pi/8 + isin 3pi/8) and sqrt 2(cos pi/12 + sin pi/12) lies.
ohaa [14]
When you multiply two complex numbers given in polar form, the argument of the product is the sum of the arguments of the factors. Meanwhile, the modulus of the product is the product of the moduli of the factors.


In this case, you'd have

\dfrac{3\pi}8+\dfrac\pi{12}=\dfrac{11\pi}{24}

and the modulus would simply be 5\sqrt2. Since

\dfrac{11\pi}{24}

we would expect the final product to fall in the first quadrant.

HELP ASAP (1O BRAILY/POINTS FOR ANSWER)
shutvik [7]

Step-by-step explanation:

x + y = 3 ---------------- eqn 1

y = -6x + 3 ------------- eqn 2

Substitute y for -6x + 3 in equation 1

x + -6x + 3 = 3

x - 6x + 3 = 3

-5x + 3 = 3

Collect like terms

-5x = 3 - 3

-5x = 0

Divide both sides by -5

x = 0

Hope this helped!

Harman [31]

Answer:

6.24

Step-by-step explanation:

A= 18.42g, B = 5.8g,C = 0.75g

Total = 18.42 + 5.8 + 0.75

= 24.97g

Then divided into four equal parts

= 24.97g/4

= 6.2425g

= 6.24g
