Part 1
Use your calculator to have it display 
and round that to five decimal places to get 
<h3>Answer: 2.71828</h3>
=============================================
Part 2
Plug in x = 5 to get
<h3>Answer: 2.48832</h3>
=============================================
Part 3
Now plug in x = 25
<h3>Answer: 2.66584</h3>
=============================================
Part 4
Plug in x = 125
<h3>Answer: 2.70749</h3>
=============================================
Part 5
As x gets larger, it appears (1+1/x)^x is getting closer and closer to e = 2.71828 since the sequence of answers (from parts 2 through 4) was 2.48832, 2.66584, 2.70749.
Answer:
6.2
Step-by-step explanation:
That is answer
Y = x^2 +2x
y = 3x +20
so:
x^2 + 2x = 3x + 20
subtract 3x from both side:
x^2 +2x -3x = 20
combine like terms:
x^2 -x = 20
subtract 20 from each side:
x^2 -x -20 = 0
factor the polynomial:
(x-5) (x+4) = 0
solve for x
x = 5 and x = -4 ( 5-5 = 0 and -4 +4 = 0 )
replace x = 5 in 2nd equation: y = 3(5) +20
y = 15 +20
y = 35
replace x with -4 in same equation:
y = 3(-4) +20
y = -12 +20
y = 8
so solution is (5,35) and (-4,8)
this equation ( /2x-1/=5)can be solved if we solve the following equations:
2x-1=5
2x-1=-5
1)We solve the first equation:
2x-1=5
2x=5+1
2x=6
x=6/2
x=2
2) we solve the second equation.
2x-1=-5
2x=-5+1
2x=4
x=-4/2
x=-2
The solutions of this equation /2x-1/=5 will be: x=3 and x=-2
Answer: x=3 and x=-2
Answer – B (Tossing a coin)
A simple event is an event where only one experiment happens at a time (such as tossing a coin), and the event has only one outcome. When two events are occurring simultaneously(such as spinning a spinner and drawing a card from a deck of cards, drawing 3 cards from a deck of cards or tossing 4 coins), then it is no longer a simple event; it is a complex event.
