why do whole numbers raised to an exponet get greater while fractions raised to an exponet get smaller
hoa [83]
Fractions are basically divisions.
Ex. 2/4 = 1/2

And whole numbers like 10, get greater when raised to an exponent.
Ex. 10^2 = 100

A line includes the points (9,0) and (-9,2). What is its equation in slope-intercept form?
horsena [70]
Y=mx+b

First use the two point slope formula to find m

(y2-y1)/(x2-x1)
(2-0)/(-9-9)
2/-18
1/-9=m

Next use the point slope formula to find the answer

y-y1=m(x-x1)

y-0=1/-9(x-9)

Now use Distributive Property 
y-0=1/-9(x)+1/-9(-9)
y-0=1/-9x+1

Your answer would be 
y=-1/9x+1

The union of two events A and B is the event that: a) The intersection of A and B does not occur. b) Both A and B occur. c) Eith
Wewaii [24]

Answer:

c) Either A or B or both occur.

Step-by-step explanation:

Suppose that we have two events

Event A

Event B

We have that:

A = a + (A \cap B)

In which a a happens and b does not and A \cap B is the probability that aboth events happen

By the same logic, we have that:

B = b + (A \cap B)

The union of events A and B is:

(A \cup B) = a + b + (A \cap B)

Which includes either one of them or both.

So the correct answer is:

c) Either A or B or both occur.
