Step-by-step explanation:
An isometry preserves the orientation of a shape. In other words, nothing will change.
In dilations, a scale factor is how many times the preimage will be increased by. In other words, this is what you multiply the x and y-coordinates by.
For example, in question 4, the image has a dilation of 2.
(3, -2) ⇒ (6, -4).

Answer:
1) The size of the colony after 4 days is 6553 mosquitoes
2) After
Step-by-step explanation:
To answer this question you must use the growth formula
Where
is the initial population of mosquitoes = 1000
t is the time in days
k is the growth rate
N is the population according to the number of days
We know that when t = 1 and then N = 1600
Then we use these values to find k.
Now that we know k we can find the size of the colony after 4 days.
To know how long it should take for the population to reach 10,000 mosquitoes we must do N = 10000 and solve for t.
