Answer:
A: Exponential
B: Quadratic
C: Linear
Step-by-step explanation:
Let analyse each table
X Y ΔY/ΔX
1 5 xxxxxx
2 11 11 - 5 = 6
3 29 29 - 11 = 18
4 83 83 - 29 = 54
.....................
We can see that, [ ΔY/ΔX ] increases at the fastest rate out of all functions, so it must be exponential function
X Y ΔY/ΔX Δ^2Y/ΔX^2
0 5 xxxxxx xxx
1 7 7 - 5 = 2 xxx
2 13 13 - 7 = 6 6-2 = 4
3 23 23 - 13 = 10 10-6 = 4
..............................
It is a quadratic because Δ^2Y/ΔX^2 = 4 and are constant for all values
X Y ΔY/ΔX
3 20 xxxxxx
6 18 2 / 3
9 16 2 / 3
15 12 2 / 3
..............
It is a linear because ΔY/ΔX = 2/3 are constant for all values
Answer:
17 will represent the batches of purple paint he wanted to make. It also represents the number of cup needed for each blue and red paint.
Step-by-step explanation:
Y = 4(-3) + 11
y = -12+11
y= -1
so y=4x+11
Answer:
diameter = IJ
radius = KH or IH or JH
chord = LM
length HK = 2
Step-by-step explanation:
if IJ is the diameter and the radius is KH then r must be 2 as the radius is always half the diameter
Answer:
y=-x+3
Step-by-step explanation:
The general slope-intercept equation of a line is y=mx+b where m is the slope and b represents the y intercept. y and x are simply a point the line passes through. In this case, y=x-5, meaning m=1 and b=-5.
In order to find the perpendicular slope, we should take the current slope's <u>negative reciprocal</u>. We have:
Therefore, our perpendicular slope is -1. We now have equation:
We can plug in the known values of the point (-1,4) to solve for b.
If we now put what we found together, we have equation
