To get the exponential model we use the form:
y=abˣ
where:
a=initial value
b=growth factor
y=number of years
thus using point (1,63) and (2,226)
the growth factor will be:
b=(226/63)=3.587~3.6
a=63
thus the formula for the function will be:
A(y)=a(3.6)^y
substituting (1,63) in the equation and solving for a.
63=a(3.6)^1
thus
a=63/3.6=17.5
hence the formula will be:
A(y)=17.82(3.6)^y
Answer: D] 17.5(3.6)^y
2] The number of acres defoliated after 5 years will be as follows:
y=5 years
A(y)=17.82(3.6)^y
plugging in the value we get:
A(y)=17.82(3.6)^5
simplifying the above
A(y)=10775.07
A(y)=10775
Answer: D
Answer:
A and D
Step-by-step explanation:
Let's find the slope of the functions in all tables.
A. -1/2
B. -1/2
C. -1/2
D. 1
E. -1/2
Option D. is out since it has a different slope.
The answer has to be two tables out of A, B, C, and E.
Start with Table A.
As x goes from 8 to 6, y goes up by 1.
We can create points for x = 0 and x = 2
x = 2, y = 9
x = 8, y = 6
This is exactly table D.
Answer: Tables A and D
Y=8x+16 or y=8x-16 hope this helps im sorry If im incorrect:)
Answer:
8 per 2 miles
Step-by-step explanation:
4 is the pickup cost
2 per mile
Jordan is riding 2 miles
so 4 + 2 + 2 = 8
