Answer:
False
Step-by-step explanation:
The left side 60.35 does not equal to the right side 15, which means that the given statement is false.
Answer:
0.5 or B
Step-by-step explanation:
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).
The answer is -4. I solved it on a calculator and got -4
Answer:
The interval of decrease is 0 ≤ x ≤ 1.25
Step-by-step explanation:
First, we have to find the point where it changes from increasing to decreasing or decreasing to increasing.
The graph shows that there is a decrease before 1.25 h, and it increases after 1.25 h also.
We can further prove that 1.25 is the point of change when we enter 1.25 in place of t in the given equation
d(1.25) = 40|1.25 - 1.25| = 0
We see that the graph is decreasing before 1.25, so the interval will have to end at 1.25.
We also see that there is no increase before 1.25, so we can make the interval begin at 0
