PLEASE HELP!!! 15 PTS!!

Answer:

$\large\boxed{C.\ (2,\ -45^o)}$

Step-by-step explanation:

Regular coordinates (x, y)

Polar coordinates (r, φ)

$r=\sqrt{x^2+y^2}\\\\\psi=\arctan\frac{y}{x}$

We have the point

$(\sqrt2,\ -\sqrt2)$

Substitute:

$r=\sqrt{(\sqrt2)^2+(-\sqrt2)^2}=\sqrt{2+2}=\sqrt4=2\\\\\psi=\arctan\left(\frac{-\sqrt2}{\sqrt2}\right)=\arctan(-1)=-45^o$

the square of a number increased by 5 times the number is equal to 176. find one number for which this could be true

avanturin [10]

Answer:

11 or -16

Step-by-step explanation:

The square of a number increased by 5 times the number is equal to 176.

Let the number be x

Then, x²+5x=176

x²+5x-176=0

We use splitting the middle term method

x²+16x-11x-176=0

x(x+16)-11(x+16)=0

(x-11)(x+16)=0

i.e. either x-11=0 or x+16=0

i.e. either x=11 or x=-16

Hence, the number is either 11 or -16
