Your scaling in the x direction is OK, but you didn't scale in the y direction properly. Hint. Scale each vertex of the original rectangle independently to construct the scaled rectangle.
I see the original points and their scaling by 2 as
(2,2) - Scales to (2*2, 2*2) = (4,4) OK in your drawing.
(-2,2) - Scales to (-2*2, 2*2) = (-4,4) OK in your drawing.
(2,5) - Scales to (2*2, 5*2) = (4,10) Error in your drawing.
(-2,5) - Scales to (-2*2, 5*2) = (-4,10) Error in your drawing.
Answer:
Step-by-step explanation:
(qor)(x)=q(r(x))=q(5x+2)=(5x+2)²-3(5x+2)-4
first find (qor)(x) as explained above
then put x=0 to get (qor)(0)
Answer:
the 2nd one
Step-by-step explanation:
Yes they are. Given that a volume of a rectangular prism is V=l•w•h, we can plug them into an equation and compare them. I'll call the Right rectangular prism figure R and the oblique rectangular prism O
For Figure R, We know all the basic needs to find the volume. This means we can plug it in.
V=l•w•h
V=12•3•5
Now We can solve for V
V=12•15
V=180
The volume of the right rectangular prism is 180in^3
Now, For figure O.
V=9•4•5
V=9•20
V= 180.
With this in mind, We now can say that the volumes of both the rectangular prisms are the same.
#6 80, 162.5
#7 .375, .4 repeating
