75 in³

x:   30

y:  20    35

Step-by-step explanation:

v = πr²h / 3

v = 3.14 * 3² * 8 / 3

v = 3.14 * 9 * 8 / 3

v = 75.36 in³

Rounded

v = 75  in³

x increase by 10 for each step

y increases by 7.5 for each step

x:   0    10      20    30     40

y:   5    12.5   20   27.5   35

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
