Answer:
[tex] a=1.58, \: \: a =-7.58[/tex]
Step-by-step explanation:
Since, circle of center (-3 , -2) is passing through the points (0 , -6) and (a , 0).
Therefore, points (0 , -6) and (a , 0) will be equidistant from the center of the circle (-3 , -2).
Hence,
Distance between (0 , -6) and (-3 , -2) = Distance between (a , 0) and (-3 , -2).
[tex] [0-(-3)]^2 + [-6-(-2)]^2=[a-(-3)]^2 + [0-(-2)]^2[/tex]
[tex] [0+3]^2 + [-6+2]^2=[a+3]^2 + [0+2]^2[/tex]
[tex] [3]^2 + [-4]^2=[a+3]^2 + [2]^2[/tex]
[tex] 9 + 16=[a+3]^2 + 4[/tex]
[tex] 25=[a+3]^2 + 4[/tex]
[tex] 25-4=[a+3]^2[/tex]
[tex] 21=[a+3]^2[/tex]
[tex] [a+3]^2=21[/tex]
[tex] [a+3]=\pm\sqrt {21} [/tex]
[tex] a=\pm\sqrt {21} - 3[/tex]
[tex] a=\sqrt {21} - 3, \: \: a =-\sqrt {21} - 3[/tex]
[tex] a=1.58257569, \: \: a =-7.58257569[/tex]
[tex] a=1.58, \: \: a =-7.58[/tex]

First, I had to find the total number of dinners, next I had to find how many had prices of "$30 or more." Last, I had to find the total number of dinners who had prices of less than $30.
Total: 10
Less than 30: 3
10 - 3 = 7
7 = Prices of Dinners ($30 or more)

Step-by-step explanation:
There are approximately 3,000 bass in a lake. The population grows at a rate of 2% per year. Round answers to the nearest tenth.
From Year 1 to Year 4, the average rate of change of the population was about 62.4 bass per year.
From Year 5 to Year 8, the average rate of change of the population was about 67.6 bass per year.
The rate of change increased by about _____ bass per a year.
Answer:
years 1–4: 62.4 bass per year
years 5–8: 67.6 bass per year
Step-by-step explanation:
If the population in year n is ...
p(n) = 3000·1.02^n
then the average rate of change from year 1 to year 4 is ...
(p(4) -p(1))/(4 -1) = 3000(1.02^4 -1.02^1)/3 = 1020·(1.02^3 -1) ≈ 62.4
The average rate of change for years 1–4 is 62.4 bass per year.
___
For years 5–8, the rate of change is similarly computed:
(p(8) -p(5))/(8 -5) = 3000(1.02^8 -1.02^5)/3 = 1000·1.02^5·(1.02^3 -1) ≈ 67.6
The average rate of change for years 5–8 is 67.6 bass per year.

The accumulation of all powers, legislative, executive, and judiciary, in the same hands, whether of one, a few, or many, and whether hereditary, self-appointed, or elective, may justly be pronounced the very definition of tyranny [oppressive government].
–Federalist, no. 47,
James Madison
What does James Madison say about the structure of the federal government in this passage and what does he seem to recommend? Check all that apply.
Power must be limited.
Power must be distributed.
Power must be contained in one branch.
Power does not belong in a branch.
Power in one place alone is tyranny.

Step-by-step explanation:
Aiden says that equivalent expressions always have the same number of terms. Is Aiden correct? If he is, explain why. If he is not correct, give a counterexample.
The opinion of Aiden about equivalent expressions always having the same number of terms is; Not correct
Mathematical OperationsAiden is not correct with his assertion as we will see for four major operations.
1) Addition; 2 + 6 = 8 and also 1 + 3 + 4 = 8.We can see that in both cases the expressions have equivalent answers but the number of terms are not the same.
2) In multiplication; 2 × 6 = 12 and also 1 × 3 × 4 = 12. We can see that in both cases the expressions have equivalent answers but the number of terms are not the same.Same scenario also applies for division and subtraction. Thus, we can say that Aiden is not correct.

A line is reflected, what line is the results?
Answer:
A I think
Step-by-step explanation:
I dont really get the question so im not sure
Answer:
C.
Step-by-step explanation:
The question states that a LINE is reflected, just with this information we know that A. is incorrect because it is curved.
At first, when looking at B., it seems as though it could work, until you notice that it starts somewhere, but doesn't end, thus it is not a LINE. So, we can count B as incorrect as well.
When looking at C, it it a straight line, and has a beginning and and end, which means that so far, it is the most likely the line.
Then, we look at D. When looking at D, we can tell that it is a straight line, however, it has no beginning and no end, thus it can't be the answer.
Now, we know that C is the only possible answer for this question.
