If the rate of change is the same on the entire graph we say it has a ____ rate of change.
Vika [28.1K]

Answer:

Constant

Step-by-step explanation:

For a straight line for example,

Take any two points from the line and find the slope,

it will be the same value for any 2 points chosen

So throughout the graph, the slope/rate of change is not changing

That is

Throughout the graph rate of change/slope is constant

You are given 2/3 angles to solve for x;

24+56 = 90

90 + x = 180

x = 90 degrees

Use the pythagoren theorem to solve x
defon
Well the equation is (A^2)+(B^2)=(C^2)

A= x
B= 2x
C will always be the longest side because it is the Hypotenuse = 25

So if you plug in those numbers into the equation...

(x^2) + (2x^2) = (25^2)

x^2 + 4x^2 = 625

Combine like terms

5x^2 = 625

Divide by five to both sides

x^2 = 125

Then Square root,

x = sqrt(125)

x = sqrt(25* 5)

x = 5sqrt(5)
