Answer:
Here is an example: if we have a rectangle that has a length 3 and a height of 4 and the scale drawing with a scale factor of 2, how many times bigger is the scale drawings area? The original shape is 3 by 4 so we multiply those to find the area of 12 square units.
Answer:
(4/3,2/3) will the point on the line after dilation
Step-by-step explanation:
Dilation is a transformation in which every point on line is dilated or multiplied away by the scale factor. This means, that dilation either enlarges the figure or reduces it in size.
So that means, if a point A(1,1) lies on a line and this line is dilated by a factor 2. Then, the new line will be passing through point
A(1,1) ---> A'(2*1,2*1) = A'(2,2)
Given: point on line (4,2) and scale factor 1/3
Result: The point is transformed or dilated by factor 1/3
B(4,2) --> B'(4/3,2/3)
Answer:1.A
2.D
Step-by-step explanation:
Interchange the x and y and solve for the resulting y.
x = 4y^2 - 2
(x + 2) = 4y^2
(x + 2)/4 = y^2
+/- sqrt(x + 2)/2 = y
The graph of these two is below.
The original is in red
The inverse is in blue and green
Answer:
Sergio's statement is false
Step-by-step explanation:
Cost of one pound of plum = 1.60
Total quantity of plum bought = 1
Weight of each plum = 1/4 pound
If he buys plum of $ 3.80 at the rate of $1.60 per pound, he purchases 2.375 pounds of plum
Weight of one plum = 1/4 pound, thus total number of plum purchased = 9.5
Since 0.5 pound of plum means half plum which is not possible to buy
Hence Sergio's statement is false
