Answer:
For this problem we have:
Initial value P = $5131Increase rate r = 8% or 0.08Time 20 years ago t = -20 30 years ago t = -30Find the value of F using the formula and substitute the values:
F(t) = P(1 + r)^tF(-20) = 5131(1 + 0.08)^(-20) = 1100.84685219 ≈ $1101and
F(-30) = 5131(1 + 0.08)^(-30) = 509.905093313 ≈ $510
Which of the following is the minimum value of the equation y = 3x2 - 4x - 2?
Answer: 3x
Step-by-step explanation:
*Remember BIDMAS*
b- brackets i- Indices (exponents) d- division m- multiplication a- addition s- subtraction
(*Reminder* exponents can be written on a keyboard like 2 squared is 2^2)
you need to follow these steps to be able to solve any equation
if there is no brackets like yours then add to make it easier
3x^2 - 4x - 2 = (3x^2) - 4x - 2
From the steps I showed you indices is first so 3x multiplied by 3x is 9x
now there is nothing left except for subtraction so solve from left to right always so 9x - 4x - 2 is 5x then 5x - 2 is 3x, x doesn’t change or gets subtracted.
i hope it helped :)

The price of Stock A at 9 A.M. was $12.95 Since then, the price has been increasing at the rate of $0.12 each hour. At noon the price of Stock B was $13.70. It begins to decrease at the rate of $0.13 each hour. If the two rates continue, in how many hours will the prices of the two stocks be the same?
Answer:
The prices of the two stocks will be the same in 1.56 hours.
Step-by-step explanation:
The price of Stock A at 9 A.M. was $12.95 Since then, the price has been increasing at the rate of $0.12 each hour.
This means that after x hours, the value of Stock A is:
[tex]S_{A}(x) = 12.95 + 0.12x[/tex]
After noon:
Noon is 3 hours after 9 AM, so
[tex]S_{A}(3) = 12.95 + 0.12*3 = 13.31[/tex]
So in x hours after noon, the value is given by:
[tex]S_{A}(x) = 13.31 + 0.12x[/tex]
At noon the price of Stock B was $13.70. It begins to decrease at the rate of $0.13 each hour.
This means that after x hours, the value of Stock B is:
[tex]S_{B}(x) = 13.70 - 0.13x[/tex]
In how many hours will the prices of the two stocks be the same?
This is x for which:
[tex]S_{A}(x) = S_{B}(x)[/tex]
[tex]13.31 + 0.12x = 13.70 - 0.13x[/tex]
[tex]0.25x = 0.39[/tex]
[tex]x = \frac{0.39}{0.25}[/tex]
[tex]x = 1.56[/tex]
The prices of the two stocks will be the same in 1.56 hours.

Mean:
Median :
Mode :
Range :
Answer:
Mean: 12.857
Median: 13
Mode: 15
Range: 9
Step-by-step explanation:
First, let's define what each of these terms mean.
Mean is the average of all the numbers in a set of data. Median is the number in the middle of a set of data after being put in ascending order. Mode is the number most frequently seen in a set of data. Range is the difference between the largest and the smallest number in a set of data.
First, let's go ahead and put all our terms in ascending order. It'll look like this: 8, 10, 12, 13, 15, 15, 17.
To find our mean, we'll add up all the terms and divide them by how many there are. First, we'll add up 8 + 10 + 12... and so on for a total of 90. Next, we'll divide 90 by 7 since there are 7 different terms in our set. 90 / 7 should roughly give you a mean of 12.857, but you can round it as needed.
Next, we'll find the median. The median is the number that is in the exact middle of a set once the terms are put in ascending order. Since, we put our terms in order already, we can see that the number in the middle of our set is 13, and I underlined it in the set to give you a visual!
Next, we'll find the mode. The mode is the number most frequently seen in our set of data. Since 15 is listed the most frequently (twice) it is our mode!
Finally, we'll find the range. The range is just the biggest number minus the smallest number. Our biggest number here is 17, and our smallest number here is 8. Just do 17 - 8 for a range of 9. Let me know if you have any other questions!

9514 1404 393
Answer:
(2/3)(e^t +1)^(3/2)
Step-by-step explanation:
Use the substitution ...
u = e^t +1
Then du = e^t and you are finding the integral of ...
∫u^(1/2)·du
which you know by the power rule is ...
(2/3)u^(3/2) = (2/3)(e^t +1)^(3/2)
