Answer:
total 3 roots,
How do I know?:
put this function in graphing calculator
And if you don't have a graphing calculator, then calculate it out bu yourself:
(x + 1)(x − 1)(x − 7) = 0
We use the formula for exponential growth:
P = Po exp(kt)
Using the population data from 1993 to 1996, we can solve for the growth rate k
76 = 72 exp(k(3))
76/72 = exp(3k)
ln (76/72) = 3k
k = ln(76/72) / 3 = 0.0180
In 10 years (2003), the population will be:
P = Po exp(0.0180t)
P = 72 exp(0.0180(10))
P = 86.22 million
Answer:
The area is changing at the point of 
Step-by-step explanation:
From the given information:
Let's recall from our previous knowledge that the formula for finding the area of a rectangle = L × w
where;
L = length and w = width of the rectangle
Suppose the Length L is twice the width w
Then L = 2w --- (1)
From The area of a rectangle
A = L × w
A = 2w × w
A = 2w²
Taking the above differentiating with respect to time

At the time t

Replacing the values back into equation 2, we get:


Answer:
f=1/25x
f=4/5f (simplified)
x=1/25f
x=4/5x (simplified)
Step-by-step explanation:
To solve for f.
fx=5−2
Step 1: Divide both sides by x.
fx/x=1/25/x
f=1/25x
To solve for x
fx=5−2
Step 1: Divide both sides by f.
fx/f=1/25/f
x=1/25f
The other side is 5 hope this helps
