Answer: 1. [-8, 8]
2. [-27, 27]
Step-by-step explanation:
1. |X|≤8
x≤8 or x>=-8
-8<=x<=8 ==> [-8, 8]
2. |X|≤27
x≤27 or x>=-27
-27<=x<=27 ==> [-27, 27]
Answer:
The area of the resulting triangle will be:
Step-by-step explanation:
The area of a triangle is
Let us suppose
As the base and height are scaled a factor of 5.
so
base = 4 × 5 = 20
height = 18 × 5 = 90
as
Therefore, the area of the resulting triangle will be:
Answer:
by
Step-by-step explanation:
we know that
To find the dimensions of the enlarged poster, multiply the original dimensions of the poster by the scale factor
so
therefore
The dimensions of the enlarged poster are by
Answer:
(x-3)^2 + (y+1)^2 =65
Step-by-step explanation:
1.find centre
2. substitute centre (h,k) into (x-h)^2 + (y-k)^2 = r^2
