Answer:

(5*sqrt(2), 5pi/4)

Step-by-step explanation:

In Polar coordinates, tan(theta)=y/x and r=sqrt(x^2+y^2)

tan(theta)=-5/5=-1. Theta=5pi/4

r=sqrt(5^2+5^2)=5*sqrt(2)

Hence the Polar coordinate is (5*sqrt(2), 5pi/4)

line L passes through point (2, -5) and is perpendicular to the line with equation y=7. determine the equation of line L
Andrew [12]

Answer:

The equation of the line L is x=2

Step-by-step explanation:

we know that

The line y=7

Is a horizontal line (parallel line to the x-axis)

The slope of a horizontal line is equal to zero

A line L perpendicular to the given line must be a vertical line (parallel to the y-axis)

The slope of the line L is undefined

The line L passes through the point (2,-5)

therefore

The equation of the line L will be equal to the x-coordinate of the given point

x=2

Anyone know the answer?
Alborosie

Step-by-step explanation:

{9}^{ \frac{ - 1}{2} }  \\  {3}^{2 \times  -  \frac{1}{2} }  \\  {3}^{ - 1}  \\  \frac{1}{3}

Now for another

{27}^{ \frac{ - 2}{3} }  \\  {3}^{3 \times  \frac{ - 2}{3} }  \\  {3}^{ - 2} \\   \frac{1}{9}

Hope it will help :)❤
