Answer:
x = {-10, 10} (Algebraic)
Step-by-step explanation:
Simplifying
4x2 = 400
Solving
4x2 = 400
Move all terms containing x to the left, all other terms to the right.
Divide each side by '4'.
x2 = 100
Simplifying
x2 = 100
Take the square root of each side:
x = {-10, 10}
2lbs of watermelon would be $1.96 because you would divide $3.92 by 4 (3.92/4) which gives you $0.98. You would then take $0.98 and multiply it by 2 ($0.98 x 2), giving you $1.96.
Answer:
-21
Step-by-step explanation:
From the graph,
f(-4) = -3
and
g(-2) = 6
Hence,
-3 -3*6
= -3 -18
= -21

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
