Answer:
B. 
Step-by-step explanation:
The vertices of triangle ABC have coordinates A(5,2) B(2,4) and C(2,1).
The mapping for reflection in the x-axis is

When we reflect triangle ABC in the x-axis, we obtain
A1(5,-2) B1(2,-4) and C1(2,-1).
The mapping for 90 degrees clockwise rotation about the origin is

When we rotate the resulting triangle through 90 degrees clockwise above the origin, we obtain;
A2(-2,-5) B2(-4,-2) and C2(-1,-2).
The vertices of triangle A''B''C'' also have coordinates A''(-2,-5) B''(-4,-2) and C''(-1,-2).
Hence the rule that describes the composition of transformation that maps ABC to A''B''C'' is

The correct choice is B.
Smaller, since a half equals to 0.50
Answer: a) 
Step-by-step explanation:
We know that the volume of an oblique pyramid is given by :-

If the volume of an oblique pyramid with a square base is V units³ and the height is h units.
Then, we have

Multiply 3 on both sides , we get

Divide both sides by h , we get

i.e. 
Hence, the expression represents the area of the base of the pyramid = 
Hence, the correct answer is a) 3 v/h units^2
Answer:
a) i) x = 6, y = 9
ii) 20
iii) -5
b) -40
Step-by-step explanation:
3(6) - 2(9)
18 - 18 = 0
greatest
3(10) - 2(5)
30 - 10
20
least
3(5) - 2(10)
15 - 20
-5
5(a - 4b)
5[-7 - 4(¼)]
5(-7 - 1)
5(-8)
-40
Hello,
I would love to answer but there is no screenshot to see!
