Answer: 7
Step-by-step explanation:
As tangents drawn from a common external point to a circle are congruent,
- 8x - 7 = 6x + 7
- 2x - 7 = 7 [subtract 2x from both sides]
- 2x = 14 [add 7 to both sides]
- x = 7 [divide both sides by 2]
N
This is because parallel lines are two lines that will never meet. The two lines on N's outside will never meet

Answer:
2^n
Step-by-step explanation:
So whenever you flip a coin, you can see it as 2 nodes branching off of each existing node. so for example when you flip a coin once you're going to have 2 sequences initially H and T, now when you flip a coin again for each of those 2 sequences 2 are going to branch off of that, making the total sequences 4, and the next flip 2 sequences are going to branch off each of the 4 sequences and so on. this can generally be described as: 2^n
I attached an image describing this a bit better but the bottom line is that for each 'end node'/sequence you're going to have 2 branch off of it, thus for each coin flip the number of sequences multiplies by 2
Answer:
133,787 residents
Step-by-step explanation:
First thing we need to do here is calculate the number of 5 years between 2020 and 1990
That would be 2020-1990 = 30/5 = 6
Now to estimate the present population, we will be needing an exponential equation
P = I(1-r)^n
where P is the present population at 2020
I is the population at 1990 which is 182,000
r is the percentage decrease every 5 years which is 5% or simply 5/100 = 0.05
n is the number of 5 years between 1990 and 2020 which is 6
Plugging all these values we have;
P = 182000(1-0.05)^6
P = 182000(0.95)^6
P = 133,786.724
To the nearest whole number, P = 133,787 residents
