Answer:

r = 5sec(θ)

Step-by-step explanation:

The usual conversion is ...

y = r·sin(θ)

x = r·cos(θ)

The second of these can be used here.

r·cos(θ) -5 = 0

r·cos(θ) = 5

r = 5/cos(θ) = 5sec(θ)

A suitable polar equation is ...

r = 5sec(θ)

What is the first step in solving the quadratic equation x2 = StartFraction 9 Over 16 EndFraction? Take the square root of both

balu736 [363]

Answer:

The first step is

Take the square root of both sides of the equation

Step-by-step explanation:

we have

$x^{2} =\frac{9}{16}$

Solve for x

step 1

Take square root both sides

$x=(+/-)\frac{3}{4}$

the solutions are

$x=+\frac{3}{4}$ and $x=-\frac{3}{4}$

therefore

The first step is

Take the square root of both sides of the equation
