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:
The least common denominator is (b-8)(b+8)(b-1)
Step-by-step explanation:
We are given expression as
Firstly, we will factor both denominators
so, we can plug it back
First term denominator is
(b-8)(b+8)
Second term denominator is
(b+8)(b-1)
So,
Least common denominator will be
(b-8)(b+8)(b-1)
So, we get
Answer:
all work is pictured and shown
Answer:
The answer to your question is the letter A) 53.1 feet
Step-by-step explanation:
Data
Adjacent side = 20 ft
angle = Ф = 67°
distance from the eyes to the ground = 6 ft
Opposite side = ?
To solve this problem use trigonometric functions. The trigonometric function that relates the Opposite side and the Adjacent side is tangent.
tan Ф = Opposite side / Adjacent side
-Solve for Opposite side
Opposite side = Adjacent side x tan Ф
- Substitution
Opposite side = 20 x tan 67
-Simplification
Opposite side = 20 x 2.36
- Result
Opposite side = 47.1 ft
Height = 47.1 + 6
= 53.1 ft
5.575 because you would need to add half of 0.05 which is 0.075
I think this right : )
