Check the picture below.
the constant of proportionality, namely the slope, for the original rectangle will just be 4/2 = 2, and for the dilated version shown that he did, it'll be 20/10 = 2.
part B)
we know the slope is 2, or 2/1 so then
12/15=8/(x-4)
12(x-4)=8(12)
12x-48=96
12x=144
x=12
Answer:
x=2
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp/ hyp
sin 30 = x/4
4 sin 30 =x
4 ( 1/2) =x
2 =x
Answer:
Volume A= one third
Step-by-step explanation:
Use volume B
Answer:
(x - 8)^2 + (y - 4)^2 = 16.
Step-by-step explanation:
The standard form can be written as:
(x - a)^2 + (y - b)^2 = r^2 where (a, b) is the center and r = the radius.
So here we have a = 8, b = 4 and r = 4.
(x - 8)^2 + (y - 4)^2 = 4^2
(x - 8)^2 + (y - 4)^2 = 16.
