2. Determine the value of x. Assume the segments that appear tangent

Mathematics

Answer:

x = 16.8

Step-by-step explanation:

To get the value of x, we use Pythagoras’ theorem since what we have is a right angled triangle

Mathematically, we have it that;

the square of the hypotenuse (21) equals the sum of the squares of the two other sides

21^2 = 12.6^2 + x^2

x^2 = 21^2 - 12.6^2

x^2 = 282.24

x = √282.24)

x = 16.8

Answer:

1. Number 1 and 2 and 4 is a function, 2. number 1 is a function

Step-by-step explanation:

1)To know if it's a function or not run vertical lines through multiple places of the graph. If it is a function every single time you do the vertical line test it should only go over the line once. If you do the vertical line test on 3 you will see that it went over the line on the graph, so we know not a function. Graphs 1, 2, and 4m however, are different, when you do the vertical line test on those graphs it only goes over them once.

2) Choice (1) is a function because when drawing vertical lines through the graph it only goes over one.

Choice (2) is not a function because when drawing vertical lines through the graph it covers two points on the graph.

Choice (3) is not a function because when drawing vertical lines through the graph it goes over multiple points.

Choice (4) is not a function because when a vertical line is drawn, it goes over more than one point on the graph.

The vertical test is a way to determine if it is a function.

When looking at a table functions are one-to-one and many-to-one

Non-functions are one-to-many and many-to-many

Hoped this helped you : )

Write the equation of the line in y=mx+b that passes through the points (5,10) and (6,12)
Damm [24]

Answer:

y = 2x + 0 or y = 2x

Step-by-step explanation:

use slope-intercept form \frac{y2 - y1}{x2 - x1}

12 - 10 = 2

6 - 5 = 1

m value = 2/1 = 2

y=2x+b

to find b plug one of the points in for x and y

Example: 10 = 2(5) + b

solve equation

10 = 10 + b

subtract 10 from both sides

0 = b

Equation of line equals y=2x+0 or simply just y=2x
