Answer:
25/9
Step-by-step explanation:
x^2 + 10/3 x
Take half of the x-term coefficient and square it.
1/2 * 10/3 = 10/6 = 5/3
(5/3)^3 = 25/9
Answer: 25/9
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%.

Answer:
b = 12
Step-by-step explanation:
c^2 = a^2 + b^2
Solving for b,
b^2 = c^2 - a^2
= (13)^2 - (5)^2
= 169 - 25
= 144
or
b = 12
