In the function f (x) = = (x²-1) / (x-1), what happens if x takes the value of 1? Explain your answer.
Answer:
If x=1, then f(x)= undefined
Step-by-step explanation:
1*1=1
1-1=0
0/0
You can't divide by 0, so anything that is divided by 0 is undefined.
((1*1)-1)/(1-1)
(1-1)/(1-1)
0/0
0/0=Undefined
f(x)= undefined
Suppose we lived in a society without interest. At age 25, you begin putting in $750 per month into a cookie jar until you retire at age 65. At age 65, you begin to withdrawl 2500 per month from the cookie jar. How long will your retirement fund last?
Answer:
the retirement fund would last 12 years
Step-by-step explanation:
first we find the amount of years one will be saving money by subtracting the age one will start saving money from the age one would start using the money.
65 - 25 = 40 years
next will be finding the amount of dollars one would save every year, we do that by multiplying the money one is saving every month by 12 (a year).
12 × 750 = 9,000 dollars per year
then we multiply the amount of money one would save per year by the amount of years one will be saving money in, to find how many dollars one would save in 40 years.
9,000 × 40 = 360,000 dollars in 40 years
-
after that we divide the amount one would have saved by the $2,500 one would use every month to find the amount of months the money would last.
$360,000 ÷ $2,500 = 144 months
to find how many years the money would last, one would divide it by 12, which is the amount of months per year.
144 ÷ 12 = 12
It will last 12 years. So it'll last till he's 77 years old at the rate he's pulling it out.
Step-by-step explanation:
You need to find the difference in the ages. so we need to find out how long he's been saving in the 1st place. 65 - 25 = 40 yearsWe now need to covert that 40 years into months. 40 × 12 = 480 months In order to know how much money he saved over that 40 years or 480 months times that by 750. 480 × 750 = 360,000Now we know over the course of 40 years he managed to save 360,000$ when he was putting in 750 a month. Now since he's retired he's taking out 2500 a month and we need to know how long it'll last.So to find out how long the 360k will last if taken out of 2500 increments just divide that rate but the total !! 360,000 ÷ 2500 = 144It will last him 144 months, now convert this number back to years. 144 ÷ 12 = 12 years So now we know it'll last him for 12 years ! and if u add 12 to 65 you'll get 77, so in 12 years he'll be 77!!This is why it'll last him 12 years, which he'll be 77 by that time !! I hope this helped !!
Verify the identity.
cot(x - pi/2) = -tan x
Use property...
cot(a+b)=cot a cot b - tan a tan b
a=x b=pi/2
Left side --> cot x+pi/2)=cot x cot (pi/2) - tan x tan (pi/2)
= cot x * 0 - tan x * 1
=0 - tan x
=- tan x
= Right side

Find the slope of the line that passes though (9,8) and (7,5)
Answer:
I think its m=3/2
Step-by-step explanation:
If it right can I please have brainliest :)
Answer:
here is how to figure this out
Step-by-step explanation:
point 1 = (9,8) = (x1,y1)
point 2 =(7,5) = (x2,y2)
slope= y2-y1 / x2-x1
slope = 5-8 / 7-9
slope = -3 / -2
slope = 3/2 :)

Given f(x) = 9x - 12. what is the value of f(5)?
Answer:
33
Step-by-step explanation:
Answer:
f(5) = 33
Step-by-step explanation:
Just plug 5 into x
f(x) = 9x - 12
f(5) = 9(5) - 12 = 45 - 12 = 33
a ferris wheel can accommodate 40 people in 25 minutes, how many people can people ride the ferris wheel in 5 hours? What's the rate per hour?
Answer:
480 in 5hrs
Rate is 96 per hour
Step-by-step explanation:
In 5 hours there are 300 minutes (5x60) and 300min/25min = 12. So 25 mins pass 12 times in 5 hours. Since each 25 mins its 40 ppl then 12x40 = 480.
480 in 5 hours so 480/5= 96 per hour

You start at (4, 6). You move up 4 units and down 8 units. Where do you end?
Answer:
(4, 2)
Step-by-step explanation:
Translation in right or left causes the x coordinate to change while translation in up or down causes the y coordinate to change.
Moving left or down causes the coordinates to be going negative.
Moving right or up causes the coordinates to be positive.
Original point (4, 6)
Up 4 units:
(4, 6 + 4) = (4, 10)
Down 8 units:
(4, 10 - 8) = (4, 2)
You end up at point (4, 2)
