One goes up and down and the other goes side to side
F(4)=6(4) +3
= 24+3=27
F(4)=27.
Answer:
y = (4/7)x² - (24/7)(x)
Step-by-step explanation:
4 = a(-1)² + b(-1)
4 = a - b
0 = a(6)² + b(6)
36a + 6b = 0
b = -6a
4 = a - (-6a)
7a = 4
a = 4/7
b = -24/7
y = (4/7)x² - (24/7)(x)
Answer:
When t=10, the town is predicted to have around 443 acres of wetlands.
At one time, the town had 740 acres of wetlands.
The wetland area in the town decreases by 5% per year.
Step-by-step explanation:
Given

Required
The true statements

We have:

Substitute 10 for t


<em>Hence, (a) is true</em>

We have:

Substitute 740 for f(t)

Divide through by 740

Express 1 as 0.95^0

Cancel out the bases


Hence, the area had 740 acres initially;
(b) is true

We have:

Using the general formula

By comparison:

0.95 < 1 means that:
--- where r = rates

Collect like terms


Express as percentage

Hence, (c) is true

In (a)

Hence, (d) is false

In (c)
---- decrement
Hence, (e) is incorrect
