KatRina [158]3 years ago
5 0

Answer:

<u>144</u>

Step-by-step explanation:

Ok. I love problems like this.

You just have to find the surface are of each part and add it up!

To find the surface area of a rectangle, you multiple the base and the height. To find the surface area of a triangle, you multiple the base and height, and divide by 2 (because its half of a rectangle).

<u>Left rectangle:</u> 3*ll=33

<u>Middle rectangle:</u> 4*ll=44

<u>Right rectangle:</u> 5*ll=55

<u>Top triangle:</u> 3*4=12

                      12/2=6

<u>Bottom triangle:</u> 3*4=12

                           12/2=6

<u>ADD THEM ALL!!!</u> 33+44+55+6+6=<u>144</u>

<u></u>

<u></u>

The equation C(l) = l3 – l2 + l + 2.5 models the cost to mail a package as a function of its length. To the nearest quarter inch
____ [38]

Answer:

2.25

Step-by-step explanation:

Given the cost model:

C(l) = l3 – l2 + l + 2.5

l = Length fo package

The length of a package that cost $11.00

11 = l³ - l² + l + 2.5

From the table given :

Length of mail which cost $11 will just be slightly greater Than 2 as the cost of 2 length mail cost 8.50

Taking l as 2.20

2.2^3 - 2.2^2 + 2.2 + 2.50 = 10.508

Taking a slightly higher value :

Put l = 2.25

2.25^3 - 2.25^2 + 2.25 + 2.50 = 11.078

Ww can conclude that the length of mail would be 2.25
