A square has four equal sides to find he area of a square multiply one side by the other. If the square is 2by2by2by2 multiply 2x2 to get the area. In this case you already have the area. The area of a square can be defined as x^2 x being the length of a side = the area x^2=A substitute the value of the are x^2=37 to simplify this expression you have to cancel out the x^2 to x. Do this by using the square root. Square root of x squared is x remember you have to do this on both sides of the equation so the square root of 37 is something like 6.081937474728774738 or something and you have to round to the nearest tenth of an inch so.. The length of a side would be approximately 6.1 inches

What is 5 1/2 - 1 2/3

user100 [1]

Answer:

3 5 /6

Step-by-step explanation:

Conversion a mixed number 5 1 /2 to a improper fraction: 5 1/2 = 5 1/ 2

= 5 · 2 + 1 /2 = 10 + 1 /2 = 11 /2

To find new numerator:

a) Multiply the whole number 5 by the denominator 2. Whole number 5 equally 5 * 2 /2 = 10 /2

b) Add the answer from previous step 10 to the numerator 1. New numerator is 10 + 1 = 11

c) Write previous answer (new numerator 11) over the denominator 2.

Five and one half is eleven halfs

Conversion a mixed number 1 2 /3 to a improper fraction: 1 2/3 = 1 2/ 3 = 1 · 3 + 2 /3 = 3 + 2 /3 = 5 /3

To find new numerator:

a) Multiply the whole number 1 by the denominator 3. Whole number 1 equally 1 * 3 /3 = 3 /3

b) Add the answer from previous step 3 to the numerator 2. New numerator is 3 + 2 = 5

c) Write previous answer (new numerator 5) over the denominator 3.

One and two thirds is five thirds

Subtract: 11 /2 - 5 /3 = 11 · 3 /2 · 3 - 5 · 2 /3 · 2 = 33 /6 - 10 /6 = 33 - 10 /6 = 23 /6

Simplify : 23/6 divide =3 5/6

The cross section of a parabolic reflector has a vertical axis of symmetry with its vertex at (0,0) . The focus of the reflector

Paha777 [63]

Answer:

The depth of the reflector is 0.84 feet

Step-by-step explanation:

<em>(See the figure below)</em>

The equation of a parabola centered at the origin with an axis of symmetry on y-axis is:

$x^{2}=4py$ (1)

With p the distance from the origin to the focus using p=6, the equation (1) of the parabola becomes:

$x^{2}=4(6)y=24y$ (2)

Note that the point B is on the parabola, so this point should satisfy the parabola equation (2) that allow us to use the value x=4.5 to find the y value associated to it, that it is the depth (h) of the reflector:

$(4.5)^{2}=24y$ , solving for y
