1 answer:

6 0

Standard form is an²+bn+c

expand
distribute
2n(3-n)+5=
2n(3)+2n(-n)+5=
6n-2n²+5=
-2n²+6n+5

g(n)=-2n²+6n+5 is standard form

Solve for x<br><img src="https://tex.z-dn.net/?f=%20%5Csqrt%7Bx%20-%202%7D%20%20%3D%200" id="TexFormula1" title=" \sqrt{x - 2}

Firdavs [7]

To solve for x, you need to isolate/get x by itself in the equation:

$\sqrt{x-2} =0$ Square ² both sides to get rid of the square root √

$(\sqrt{x-2} )^2=(0)^2$

x - 2 = 0 Add 2 on both sides

x - 2 + 2 = 0 + 2

x = 2

A city-wide gardening club is up of men, women and children in the ratio 5:4:11.

Sever21 [200]

Answer:

Women: 448 Men: 560 Children: 1232

Step-by-step explanation:

5+4+11 = 20/2240 = 112

Women = 4 x 112 = 448

Men = 5 x 112 = 560

Children = 11 x 112 = 1232

Total = 1232 + 560 +448 = 2240

Suppose that P is the point on the unit circle obtained by rotating the initial ray counterclockwise through 330 degrees. Find t

Flauer [41]

Answer:

Reference angle will be 30°

sin(330°) will be equal to $\frac{-1}{2}$

cos(330°) will be equal to 0.866

Step-by-step explanation:

We have given angle is 330°

As the angle $330^{\circ}$ is in forth quadrant

We know that in forth quadrant the reference angle is given by

Reference angle $=360-angle$

As the angle is 330°

So the reference angle will be $=360-330=30^{\circ}$

Now we have to find the value of

sin(330°) $=sin(2\pi -30)=-sin(30)=\frac{-1}{2}$

And now $cos(330^{\circ})=cos(2\pi -30)=cos30=0.866$
