Answer:
B'(16,14)
Step-by-step explanation:
First find the coordinates of the vertex B. The center of the square M is the midpoint of the diagonal AC. Since A(2,7) and C(8,1), the center has coordinates

Point M is also the midpoint of the diagonal BD. Let B has coordinates (x,y), then

Hence, B(8,7).
Now, the dilation by a scale factor 2 with the center of dilation at the origin has the rule
(x,y)→(2x,2y).
Thus,
B(8,7)→B'(16,14).
Answer:
He had 189 dollars
Step-by-step explanation:
35% of 140 is 49
140 plus 49 is 189
Answer: Identify whether each scenario would be represented by a continuous or discrete graph
Step-by-step explanation:
Answer:
11.4 x 10 ^ 6
Step-by-step explanation:
- First, you have to convert 3.8 x 10^5 out of scientific notation. To do that, multiply 3.8 * 10^5, you'll get 380,000. This is the weight of each whale.
- Now multiply the weight of each whale times 30. 380,000 * 30 = 11,400,000
- Convert back to scientific notation. 11.4 x 10^6
