3w(w) = 48
3w^2 = 48
w^2 = 48/3
w^2 = 16
w = sqrt 16
w = 4
Answer:
5
Step-by-step explanation:
The gradient is simply the change in y divided by the change in x.
Change in y is the difference in y-coordinates, while the change in x is the difference in x-coordinates. Our two points here are (1, 5) and (6, 35).
The difference in y-coordinates is: 35 - 5 = 30. The difference in x-coordinates is: 6 - 1 = 5. Divide 30 by 5:
30 / 5 = 6
Thus, the gradient is 5.
Let:
L = Length
W = Width
The length is 7cm longer than its width, so:
The area is given by:
Therefore:
Solve for W using the quadratic formula:
Therefore:
W = 12.38238 since a negative width wouldn't make any sense
and:
Answer:
W = 12.38238 m
L = 19.38238 m
Given:
The point (5,0) dilated by a scale factor of 3 centered at the origin.
To find:
The coordinates of image.
Solution:
If a figure dilated by a scale factor of k centered at the origin, then the rule of transformation is
The point is dilated by a scale factor of 3 centered at the origin, then the rule of transformation is
The given point is (5,0). Putting x=5 and y=0, we get
Therefore, the image of (5,0) is (15,0).
