Write the exact value of the side length of each square. If the value is not a whole number, estimate the length.
Savatey [412]

Given:

The area of the squares are given.

To find:

The exact side length or estimate side length of the square.

Solution:

We know that, the area of a square is

A=a^2

Where, a is the side length of the square.

a=\sqrt{A}

Area of the square is 100 square units. So, the side length is:

a=\sqrt{100}

a=10

Therefore, the side length is 10 units.

Area of the square is 95 square units. So, the side length is:

a=\sqrt{95}

It is not exact. We know that \sqrt{81}.

Therefore, the side length is between 9 and 10.

Area of the square is 36 square units. So, the side length is:

a=\sqrt{36}

a=6

Therefore, the side length is 6 units.

Area of the square is 30 square units. So, the side length is:

a=\sqrt{30}

It is not exact. We know that \sqrt{25}.

Therefore, the side length is between 5 and 6.

Convert the Cartesian equation x - 5 = 0 to a polar equation.
mylen [45]

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)

nignag [31]

Answer:

A Sarah earns more money per hour  $15

Step-by-step explanation:

We need to find the slope to determine the rate ( amount per hour

Sarah

m = (y2-y1)/(x2-x1)

    = (50-5)/(3-0)

    = 45/3

    = $15 per hour

Mia

m = (y2-y1)/(x2-x1)

   = (20-10)/(2-0)

    = 10/2

   = $5 per hour
