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%.

Step-by-step explanation:
you can't use a calculator ?
that is all that is needed.
the original price $312.
it is $145 off.
so, the actual sales price is : 312 - 145 = $167
If the two angles form a linear pair, the sum of the angles is 180 degrees.
If the small angle is one-third of the other, then the total is 1+1/3=4/3 of the larger angle.
By proportion,
L+L/3=4L/3=180
L=180*3/4=135 degrees
Smaller angle = L/3=45 degrees
Check: L+L/3=135+45=180 degrees, ok

D = devaugn's age
s = sidney's age
so, we know Devaugh's age is twice as Sydneys, so d = 2*s or 2s
and we know their sum is 66
or d + s = 66
since d = 2s, thus
(2s) + s = 66 <--- solve for "s" to see Sidney's age
what about Devaugn's? well d = 2s
