V = 1/3Bh

B = 1/2(b1 + b2)t

V = 1/3[1/2(b1 + b2)t] * h

h = 24

b1 = 13

b2 = 29

t = ?

V = 2856

Substitute:

2856 = 1/3[1/2(13 + 29)t](24)

2856 = 1/6(42)(24)t

2856 = 7(24)t

2856 = 168t

t = 2856/168 = 17 in height of the trapeziod

**Given:**

In 2010, the population of a town = 2000

Every year, it increase by 1.5%

**To find** the equation P(t) which represents the population of this town t years from 2010.

**Formula**

If a be the original population of a town and it increases by b% every year, after t year the population will be

Now,

Taking, a =2000, b = 1.5 we get,

or,

Hence,

The population of this town t years from 2010 P(t) = , **Option D.**

You have to put it in y intercept form. I hope the picture helps

For the y intercept let x = 0

and you'll get -10

for the x intercepts you must solve for x:

Commutative property: when you have to solve a sum, it does not matter the order in which you place your addends, since you will always get the same result.

We have then:

((40) + (185)) + (240) = 465

(240) + ((40) + (185)) = 465

** answer:**

** Form 1:**

** ((40) + (185)) + (240) = 465**

** Form 2:**

** (240) + ((40) + (185)) = 465**
