Answer:
Step-by-step explanation:
if it is linear then it will be a straight line(gradient is the same)
if quadratic then curve(gradeint isnt the same)
y=mx+c
m=[y(2)-y(1)]/[x(2)-x(1)]
you can choose any 2 points from the table
m=2-0.4/0-1
m=-1.6
repeat but 2 different coordinates
m=0.4-0.08/-1--2==>-2.24
m=-2.24
different coordinate therefore quadratic
cant be exponential, because nothing is being raised to some power
Hi there Maebe, since the ratio is 3:1 your answer is 96.
The ratio 3:1 is just saying Juanita has 3 times whatever Elita has. So, Elita’s 32 times 3 equals 96. :) I hope I’ve helped you. Please give me feedback if you need more help understanding!
It will take 6 years for the trees to have same height.
Step-by-step explanation:
Type A tree;
Initial height = 9 feet
We will convert feet into inches because growth is in inches.
1 feet = 12 inches
9 feet = 12*9 = 108 inches
Growth rate = 6 inches per year
Let,
x be the number of years.
A(x) = 108 + 6x
Type B;
Initial height = 4 feet = 4*12 = 48 inches
Growth rate = 16 inches per year
B(x) = 48 + 16x
The height will be same, when functions are equal
A(x) = B(x)
![108+6x=48+16x\\108-48=16x-6x\\60=10x\\10x=60](https://tex.z-dn.net/?f=108%2B6x%3D48%2B16x%5C%5C108-48%3D16x-6x%5C%5C60%3D10x%5C%5C10x%3D60)
Dividing both sides by 6
![\frac{10x}{10}=\frac{60}{10}\\x=6](https://tex.z-dn.net/?f=%5Cfrac%7B10x%7D%7B10%7D%3D%5Cfrac%7B60%7D%7B10%7D%5C%5Cx%3D6)
It will take 6 years for the trees to have same height.
