Answer:
Option D
Step-by-step explanation:
The compounded interes formula states that:
V(t) = P (1 + r/n)^ (nt)
t = years since initial deposit = 3
n = number of times compounded per year 1
r = annual interest rate (as a decimal) = 4% / 100 = 0.04
P = initial (principal) investment = $500
Then V(t) = $500 ( 1 + 0.04/1)^3 = 562,43
So the correct answer is option D.
Answer:
5 <= y <= 85
Step-by-step explanation:
Since the lowest weight possible is 5lbs (just the barbell and no weights) the lowest point of the range is 5lbs (the y intercept when x = 0)
The highest weight possible is 85lbs since, there is only 8 pairs of weight plates (8 is the input value) and the pairs each weigh 10lbs (the slope of the graph) + 5lbs from the barbell (y-intercept).
Using the function given, if you input 8 as the x value, you get
85 = 10(8) + 5
So the highest value of the range is 85lbs, therefore the range is 5 <= y <= 85.
Answer:
Is seven times the difference of a number and 4 no more than 10?
If 
has to be a solution of the equation, just plug it in:
![(\pm 15i)^2 + [1] = 0 \iff -225 + [1] = 0 \iff [1] = 225](https://tex.z-dn.net/?f=%20%28%5Cpm%2015i%29%5E2%20%2B%20%5B1%5D%20%3D%200%20%5Ciff%20-225%20%2B%20%5B1%5D%20%3D%200%20%5Ciff%20%5B1%5D%20%3D%20225%20)
So, the solutions of
