A = acres, s = square miles.
Replace s with 7.5 and multiply:
640 * 7.5 = 4,800 acres.
The answer is the last choice.
Answer:
Step-by-step explanation:
Essentially, begin by flipping the x and y terms:
x = (1 - 2y)^2 + 5
Then, solve for y:
Because we know there is only 1 y-value for any given x-value, the inverse of the given function is also a function.
Answer:
centre of dilation = origin (0,0)
scale factor = 3
Step-by-step explanation:
<em>In order to figure out the scale factor you just have to realise when you do a dilation, the distance between corresponding points will change according to the scale factor.</em>
By looking at the triangle B in the graph the height is 3 units
similarly corresponding height of triangleA is 1 unit
For an dilation = large number ÷ small number
So our scale factor right over here is 3.
In order to identify centre of dilation draw a straight line from end point of height of small and large triangle and make a triangle out of this.
That straight line will be hypotenuse of the triangle and it will be exactly as large as the triangle B.
A=L*W
A=8.5*3.4
A=28.9 ft squared
