Answer:
A
Step-by-step explanation:
We plot the points (x,y) in the coordinate system and the points are shown in the diagram attached.
We can draw a line y = -6 connecting the RED and BLUE points. Also, we can draw a line x = 9 connecting the BLUE and GREEN points.
The intersection of these two PERPENDICULAR LINES is at the point (9, -6) (as seen --- The blue point). So, when two perpendicular lines intersect, that point is a right angle.
So, the 3 points given INDEED make a right triangle.
So, correct answer is A
Answer:
The correct option is (C).
Step-by-step explanation:
The exponential function representing decay is as follows:
Here,
<em>y</em> = final value
<em>y</em>₀ = initial value
<em>k</em> = growth rate
<em>t</em> = time passed
The graph represents exponential decay is:
"On a coordinate plane, a graph approaches y = 0 in quadrant 1 and curves up into quadrant 2."
Thus, the correct option is (C).
