Given:

We get the points (0,6), (3,32), and (12,770) from the given table.

Let y be the number of the rabbit and x be the number of months.

Consider the regression equation of the form.

$y=a(b)^x$

Substitue x=0 and y=6 in the equation, we get

$6=ab^0$

$a=6$

Substitue x=12 and y=770 in the equation, we get

$770=ab^{12}$

$\text{ Substitute }a=6\text{ in the equation, we get}$

$b^{12}=\frac{770}{6}$

$b^{}=\sqrt[3]{\frac{309}{32}}$ $undefined$

For the table below, determine the function rule, and find each of the missing y-values.

anygoal [31]

The answer is 8 and 13

<span>
y = ax + b
y = 4, x = 1 </span>⇒ 4 = a + b
y = 6, x = 3 ⇒ 6 = 3a + b

Solve the system of equation:
a + b = 4
3a + b = 6
______
b = 4 - a
3a + b = 6
______
3a + 4 - a = 6
2a + 4 = 6
2a = 6 - 4
2a = 2
a = 2/2 = 1
b = 4 - a = 4 - 1 = 3

So, the function rule is: y = x + 3

Thus, if x = 7, then y = 7 + 3 = 10
If x = 10, then y = 10 + 3 = 13

x y

The population of a city has decreased by 35% since it was last measured. If the current population is 9100 , what was the previ

Alina [70]

The previous population was 14000.

Explanation

The population decreased by 35% since the last measurement. So the current population is less than the previous population.

current population=9100

previous population =x

current population is 35% less than the previous population x

$9100=x*(100-35)/100\\9100=(x*65)/100\\x=(100*9100)/65=14000$

The previous population was 14000.
