Answer:
The graph should look like the graph of ![f(x)=230*(1.15)^x](https://tex.z-dn.net/?f=f%28x%29%3D230%2A%281.15%29%5Ex)
Step-by-step explanation:
The question is an exponential function problem because the price increase is dependent on the previous price. NOT the initial price. Therefore, using the
formula, and plugging in the corresponding values, we get the answer.
<span>Given:
AB = x + 16
BC = 4x + 11
AC= 77
We can safely assume that,
AB + BC = AC
x + 16 + 4x + 11 = 77
5x + 27 = 77
5x = 77 - 27
5x = 50
x = </span>
![\frac{50}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B50%7D%7B5%7D%20)
x = 10
Hence,
AB = x + 16 = 10 + 16 = 26
Hence, proved.
Answer:
Velocity (against wind) = 1,890 / 3 = 630 mph
Velocity (with the wind) = 1,890 / 2.5 = 756 mph
Plane speed (still air) = 630 + wind speed
Plane speed (still air) = 756 - wind speed
Adding both equations equals
2 * Plane speed (still air) = 1,386
Plane Speed = 693 mph

Step-by-step explanation:
I don't think it really matters if the denominator is negative in a literal equation. Think about a simpler example with numbers. Does it matter whether a fraction is -1/2 or 1/-2? No, they are both the same. Therefore, I would say that the denominator of a literal equation can be negative.
Good luck with your exams!
