The area consist of rectangle and trapezoid.

Determine the area of composite figure by add area of reacangle and area of trapezoid.

$\begin{gathered} A=5\cdot3+\frac{10+5}{2}\cdot(7-3) \\ =15+\frac{15}{2}\cdot4 \\ =15+30 \\ =45 \end{gathered}$

So area of the figure is 45 square centimeter.

19) 15 <= 9 + 3x

15) x = 23,24,25

17) x <= 115

9) Second line

11) g > 20, don't fill in dot, any number greater than 20

1) -3 + h<= 3.4

3) No, x > -2

5) x > 14, don't fill in dot, any number greater than 14

7) k<=20, fill in dot, 20 or any larger number

A population of mice is increasing exponentially. On Monday there were 120 most. One month later there were 132 most. Ready func

djyliett [7]

Answer:

$y=120 * 1.1^x$ --- function

The monthly rate is 10%

Step-by-step explanation:

Given

Let

$x \to months$

$y \to mice$

So, we have:

$(x_1,y_1) = (0,120)$ --- Monday

$(x_2,y_2) = (1,132)$ --- One month later

Required

The function

The function is represented as:

$y=ab^x$

In $(x_1,y_1) = (0,120)$ , we have:

$120 = a * b^0$

$120 = a * 1$

$120 = a$

$a=120$

In $(x_2,y_2) = (1,132)$ , we have:

$132 = a * b^1$

$132 = a * b$

Substitute: $a=120$

$132 = 120 * b$

Solve for b

$b = \frac{132}{120}$

$b = 1.1$

So, the function is:

$y=ab^x$

$y=120 * 1.1^x$

To calculate the monthly rate (r), we have:

$y =a(1 + r)^x$

Compare to: $y =ab^x$

$1 + r = b$

Make r the subject

$r = b-1$

Substitute $b = 1.1$

$r = 1.1-1$

$r = 0.1$

Express as percentage

$r = 0.1*100\%$

$r = 10\%$
