Let x be the time and y is the depth
At x = 0 y = -130
At x= 6.5 y = 0
So the slope = (0- (-130) / ( 6.5 – 0) = 20
Y intercept b
0 = 20(6.5) + b
B= -130
The equation
Y = 20x -130
The domain all real numbers from 0 to 6.5
Range is all realnumber from -130 to 0
The answer is E because 12²
So hmmm notice the picture below
thus
solve for "h"
Since we know the degrees of the circle is 360, add all of the pieces together and set equal to 360
Solving you get x = 15.
When plugging 15 back into each expression we get 90, 160, and 110.
This means the triangle sides are all different so the triangle is scalene.
