It is not a function because there can't be two of the same number on the x-axis.

The population of a town grows exponentially. After 1 year, the population is 34,560. After 2 years, the population is 37,325. W

Vladimir [108]

Exponential growth has the form:

F=Ir^t, F=final amount, I=initial amount, r=rate, t=time.

First let's solve for the rate, r, using the points provided...

37325/34560=(Ir^2)/(Ir^1)

r≈1.08

Now find the initial amount...

34560=I(1.08)^1

I=32000 so now we have the entire equation, using x and y...

y=32000(1.08)^x

A survey among American adults concluded that 20% of adults believe Elvis is still alive, 10% believe they've been abducted by a

Kitty [74]

Answer:

$P(Alive\ or\ Aliens) = 26\%$

Step-by-step explanation:

Given

$P(Alive) = 20\%$

$P(Aliens) = 10\%$

$P(Alive\ and\ Aliens) = 4\%$

Required

Determine $P(Alive\ or\ Aliens)$

From laws of probabilities:

$P(A\ or\ B) = P(A) + P(B) - P(A\ and\ B)$

In this case:

$P(Alive\ or\ Aliens) = P(Alive) + P(Aliens) - P(Alive\ and\ Aliens)$

$P(Alive\ or\ Aliens) = 20\% + 10\% - 4\%$

$P(Alive\ or\ Aliens) = 26\%$

If the endpoints of `bar(AB)` have the coordinates A(9, 8) and B(-1, -2), what is the midpoint of `bar(AB)`?

alina1380 [7]

To solve this problem you must apply the proccedure shown below:

1. You have the following points given in the problem above:

$A(9,8)\\ B(-1,-2)$

2. To find the midpoint, you must apply the formula that is used for calculate it. This is:

$m=(\frac{x1+x2}{2}, \frac{y1+y2}{2} )$

Where:

$x1=9\\ x2=-1\\ y1=8\\ y2=-2$

3. Now, you must substitute these values into the formula for calculate the midpoint, as following:

$m=(\frac{9+(-1)}{2} ,\frac{8+(-2)}{2} )\\ m=(4,3)$

Therefore, the answer is: $m=(4,3)$
