Answer:
582 (C)
Step-by-step explanation:
The side closest to us (and the back too) is 9*9 + (15-9)*(15) = 81 + 90 = 171 *2 sides = 342
The top and bottom faces are: 15*4 = 60 * 2 sides = 120
The left side + right side = 15*4 * 2sides = 120
120+120+342 =
582
Answer: Option B.
Step-by-step explanation:
If a varies directly with b then when a increases b it also increases by a factor k.
Then we can write that
We know that when a = 28 then b = 7. So
Therefore the equation of proportionality is:
So when 
then:
Using translation concepts, the images of the points are given as follows:
25. (4,3).
26. (3,1).
<h3>What is a translation?</h3>
A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.
The rule for a reflection across y = x is given by:
(x,y) -> (y,x).
Hence, in item 25:
The image of (3,4) is (4,3).
The rule for a reflection across y = -x is given by:
(x,y) -> (y,-x).
Hence, in item 26:
The image of (-1,3) is (3,1).
