60.56ft

You can get this by creating right triangles with the adjacent side as 20 and using the angles given. You can then find the opposite sides using tangents and then simply add them together. <span />

stira [4]

Answer:

Width = 36in

Size = 42.02

Step-by-step explanation:

Given

x \to width

y \to height

x : y = 16 : 9

Required

The size of screen of height 20,6in

First, we calculate the width using the following equivalent ratios

16: 9 = x : 20.6

Express as fraction

\frac{16}{ 9} = \frac{x }{ 20.6}

Solve for x

x = 20.6 * \frac{16}{ 9}

x = 36.62

Hence:

Width = 36in --- approximated

So, we have:

x = 36.62

y =20.6

The size (diagonal) is then calculated using:

Size = \sqrt{x^2 + y^2

Size = \sqrt{36.62^2 + 20.6^2

Size = \sqrt{1765.3844

Size = 42.02

Size =42in --- approximated

Define a function. Describe what the vertical line test is used for. Describe a real life situation that can be represented by a
Marrrta [24]
A function is a relationship with a quantity (number). For example, if you made a table, and had one side be 1 2 3 4 5 (X axis) and then the y axis (other side) be 5, 10, 15, 20, 25, the function (rule) would be y= x5. The vertical line test is used to see if a graph has a function or not, so if it creates a vertical line on a graph, it has a function.
A real life situation would be miles per hour, so, for the x axis (hours) it said 1, and for the y axis (miles) it would be 60, this means in a duration of 1 hour you went 60 miles. Well, lets say you went 2 hours driving, the miles would be 120. 
For 3 hours, it would be 180. The function here is y= x60!
