I will have $2721 at the beginning of the eighth year.
The beginning of the eighth year is the end of <em>seven years of investing</em>.
The formula for the future value (FV) of my investment is
FV = <em>C</em>(1 + <em>r</em>)^<em>n</em>
where <em>C</em> = my initial cash
<em>r</em> = the interest rate
<em>n</em> = the number of years
FV = $2000(1.045)^7 = $2722
Answer:
(1, 0)
Step-by-step explanation:
x = -b / 2a
x = 2 / 2(1)
x = 2 / 2
x = 1
y = x^2 - 2x + 1
y = (1)^2 - 2(1) + 1
y = 1 - 2 + 1
y = -1 + 1
y = 0
vértice: (1, 0)
-8/7J +13
Here’s a picture to see how to write it
You would do for pens
22 x 1.15 =25.30
And for markets
15 x 2.05 = 30.75
And since you are trying to find how much he spent in all you would add the two sums
25.30 + 30.75 = 56.05
f(x) = -5x - 15
Let y = f(x)
y = -5x - 15
Switch the x and y places, and solve for y:
x = -5y - 15
-5y = x + 15
y = (x + 15)/-5
y = -(x/5) - 3
So the inverse of : f(x) = -5x - 15 is
-x/5 - 3
