The exponential model indicates that hydropower energy generation has increased by 2.3% (0.023).
<h3>What is an exponential function?</h3>
An exponential function can be defined as a type of mathematical equation whose numerals are generated by a constant that's raised to the power of an argument.
Based on an exponential model for this data, we can deduce the following:
- Mathematically, the exponential function for the given data is given by
- The exponential model indicates that hydropower energy generation has increased by 2.3% (0.023).
- Hydropower energy generation in 25 years after 1970 was closest to 2270 TWh.
- Because the correlation coefficient indicates a strong correlation between the model and the data, this prediction can be accepted with confidence interval of 98.7%.

X - the number of fish
8/11 of the fish have a red stripe.
16 of the fish have a red stripe.
There are
22 fish in the tank.
Hi,
We know that:
a² -- b² = (a -- b)(a + b).
With a = x, and b = 4, we have:
x² -- 16 = x² -- 4² = (x -- 4)(x + 4).
As simple as that. Have you understood ?
Green eyes.
Answer:
I just learned this topic and have the same question, so I'm not sure if this right. However, I see a fellow student struggling and have to at least put in what I know. My equation was f(n) = 64(1/2)^n-1, then the question was write an expression to represent f(20).
Step-by-step explanation:
So, my answer was f(20) = 64(1/2)^19
f(20) is the number you plug into n. And because the exponent is n-1, I knew to subtract 1 from 20 to get 19.
Then I just wrote the equation out like the original expect with the numbers pluged in: f(20) = 64(1/2)^19
I hope this helps!
Answer:
no, it is 38.5
Step-by-step explanation:
you have to add up the two numbers that are in the middle then divide it by two since there isn't just one number in the middle.
