Completely raw guess here but idk 3/5 cause you said two is decreased from both
Answer:
1. The equation represent an exponential decay
2. The rate of the exponential decay is -3×2.5ˣ·㏑(2.5)
Step-by-step explanation:
When a function a(t) = a₀(1 + r)ˣ has exponential growth, the logarithm of x grows with time such that;
log a(t) = log(a₀) + x·log(1 + r)
Hence in the equation -3 ≡ a₀, (1 + r) ≡ 2.5 and y ≡ a(t). Plugging in the values in the above equation for the condition of an exponential growth, we have;
log y = log(-3) + x·log(2.5)
Therefore, since log(-3) is complex, the equation does not represent an exponential growth hence the equation represents an exponential decay.
The rate of the exponential decay is given by the following equation;
Hence the rate of exponential decay is -3×2.5ˣ × ㏑(2.5)
Double of 50 is 100, so 28*100=2800, now half of the answer is 2800/2=1400
F(x) = x2-3 The domain of a polynomial is all x: (-∞,∞)Since f(x) is a quadratic equation, its graph is a parabola. Since the coefficient of the x2 term is positive (1), the graph opens upward and the vertex is at the bottom and is the lowest or minimum point of f(x). The vertex is located at the point (0,-3). Hence the range is from -3 to infinity: [-3,∞)
The Median is 11, and it is shown by the line on the middle of the rectangle.
The range is 12, and you can find it by subtracting the highest data point (17) by the lowest data point (5).
The 25th percentile is 9, and it could be found by looking at the first line in the rectangle.
The 75th percentile is 14, and it could bee found by looking at the last line in the rectangle.
The inter-quartile range is 5, and it can be found by subtracting the upper quartile, or the 75th percentile (14) by the lower quartile, or the 25th percentile (9). 14-9=5
Hopefully this helps.
