Answer:

Table 2

Step-by-step explanation:

<h3>Table 1</h3>

x- values change 1 to 4
y- values change inconsistently and repeat at -2

This is <u>not</u> a linear function

<h3>Table 2</h3>

x- values change 1 to 4
y- values change consistently, with common difference of -2

<u>This is a linear function</u>

<h3>Table 3</h3>

x- values change 1 to 4
y- values change inconsistently, the difference is not common

This is <u>not</u> a linear function

<h3>Table 4</h3>

x- values change 1 to 4
y- values change inconsistently, the difference is not common

This is <u>not</u> a linear function

$A=189\ mm^2$

Step-by-step explanation:

<u>Surface Areas </u>

Is the sum of all the lateral areas of a given solid. We need to compute the total surface area of the given prism. It has 5 sides, two of them are equal (top and bottom areas) and the rest are rectangles.

Computing the top and bottom areas. They form a right triangle whose legs are 4.5 mm and 6 mm. The area of both triangles is

$\displaystyle A_t=2*\frac{b.h}{2}=b.h=(4.5)(6)=27 mm^2$

The front area is a rectangle of dimensions 7.7 mm and 9 mm, thus

$A_f=b.h=(7.5)(9)=67.5 \ mm^2$

The back left area is another rectangle of 4.5 mm by 9 mm

$A_l=b.h=(4.5)(9)=40.5 \ mm^2$

Finally, the back right area is a rectangle of 6 mm by 9 mm

$A_r=b.h=(6)(9)=54 \ mm^2$

Thus, the total surface area of the prism is

$A=A_t+A_f+A_l+A_r=27+67.5+40.5+54=189\ mm^2$

$\boxed{A=189\ mm^2}$

10. A trapezoid has base lengths of 24 units and 20 units. The height of the trapezoid is one-half as long as the

lana [24]

Answer:

264 units.

Step-by-step explanation:

since the two bases are 20 and 24, the shorter base is usually the shorter number, so the shorter base is 20 units. Which means, the longer base is 24 units. So, half of 24 is 12. So, the height is 12. Then I used to calculator, my results are in the picture below.
