Exponential functions model exponential increase/decrease; in this case, we must understand that exponential functions differ from linear functions, which increase, well, linearly: the function can be represented by a straight line. In real-world terms, that means stuff increases/decreases constantly, not at a changing rate.
For this question, (B) and (D) are not modeled by g(x) because they increase linearly: a set amount of things happen per unit of time.
So, (A), (C), and (E) can be modeled by exponential functions because they double per time unit. However, (C) is not modeled by g(x) because it doubles every 5 hours (time units). If we look at g(x), it doubles every time unit (2^x, where x is the time unit). (A) and (E) double every time unit (every year), while C doubles every 5 time units (every 5 hours).
So, your answer would be (A) and (E).
Short note: What does g(x) actually mean?
Well, 100 represents the initial input: whether that be height, money, or population. That's your starting value you base your function off of. 2 is the base: how much your input changes exponentially: 2 is doubling, 3 is tripling, etc. Similarly, 0.5 is halving, and so on. As x is the exponent, it tells you how long it takes for your input to change by the base: 1x is per 1 time unit, 0.5x is per 2 time units, 0.25 is per 4 time units, and so on. Conversely, 2x is per 0.5 time units, 4x is per 0.25 time units, and so on. This is because, for 0.5x, it takes us double the time (2 time units) for the input to change by the base. Similarly, for 2x, it only takes us half the time (0.5 time units) for the input to change by the base. If you are able to apply this understanding to exponential functions like g(x), you can understand what they represent, and what they can model. Similarly, you can look at worded examples of exponential functions and see how they could be represented mathematically. That's the most important thing to learn.
Probability is the result of the division of the number of possible outcome by the number of an event.
In the question, for a point chosen, the point can be in the small square only or in the area or region between the small square and the big square as such,
Area of larger square = area of region between both squares + area of smaller square
Where the area of a square is S × S where S is the side of a square
Area of larger square = 10 × 10
= 100 cm square
Area of smaller square = 7 × 7
= 49 cm square
Area of the region between both squares
= 100 - 49
= 51 cm square
The probability that a dot selected is inside the larger square and outside the smaller is
P(inside larger square and outside smaller) = Area of region between both square/ Area of larger square
The given ratios 3: 5 and 15: 25 are equal. Because when you divide the ratio 15: 25 by 5 on both numerator and denominator, the first ratio 3: 5 can be obtained. Similarly, when you multiply the first ratio 3: 5 by 5, the ratio 15: 25 can be obtained.
the plans can go 560 miles per hour and in 10 hours it can travel 5600 miles
Step-by-step explanation:
1st divide miles over hour so you have to do 3360/6 and the solution you get for that equation is how far the plane can go in miles per hour 2nd for the second question you have to multiply your unit rate by the 10 hours so since our unit rate was 560 miles per hour you would multiply 360 and 10.
