To make it easier to graph this equation, you can manipulate it to get it in slope-intercept form. You'd do that like so:
7x + y = -7
y = -7x - 7
Now I can graph a bit more easily as I can more readily make out the slope and the y-intercept...
The perimeter is 6·(2 ft) = 12 ft. The apothem is (2 ft)/2·tan(60°) = √3 ft. The area is ...
A = (1/2)Pa = (1/2)(12 ft)(√3 ft) = 6√3 ft² ≈ 10.4 ft²
Answer:
2267
Step-by-step explanation:
Answer:
a) About 12%
Step-by-step explanation:
We need to find the interest rate required to achieve her goal, so we will need to use the interest-compound formula:

Where:
PV= Present Value
i= interest rate
FV= Future Value
n= number of periods
replacing the data provided:

solving for i:
first, divide both sides by 50.000 to simplify the equation:

Take
roots of both sides:
±![\sqrt[10]{3}](https://tex.z-dn.net/?f=%5Csqrt%5B10%5D%7B3%7D)
solve for i:
±![\sqrt[10]{3} -1](https://tex.z-dn.net/?f=%5Csqrt%5B10%5D%7B3%7D%20-1)
We get two answers, but we look for a coherent value. So we take the positive one:
≈12
