Answer:
(b) P(t) =7,200(1.03)^(t)
Step-by-step explanation:
The multiplier each year for the population is about ...
7416/7200 = 1.03
The initial value is 7200, so the exponential function can be written as ...
P(t) = 7200×1.03^t
_____
<em>Additional comment</em>
In plain text, the exponent is signified by a caret (^). Without it, the expression becomes a linear function. In typeset text, the exponent should be in a superscript font. (We notice that curriculum materials do not always properly represent exponential functions.)

Answer:
x = -2 ±sqrt(7)
Step-by-step explanation:
3x^2 +12 x = 9
Divide each side by 3
3x^2 /3 +12x/3 = 9/3
x^2 +4x = 3
Take the coefficient of x
4
Divide by 2
4/2 =2
Square it
2^2 =4
Add it to each side
x^2 +4x+4 = 3+4
x^2 +4x+4 = 7
(x+2)^2 = 7
Take the square root of each side
x+2 = ±sqrt(7)
Subtract 2 from each side
x+2-2 = -2 ±sqrt(7)
x = -2 ±sqrt(7)
