Answer:
see explanation
Step-by-step explanation:
The exponential function is in the form
y = a
Use points on the graph to find a and b
Using (0, 3), then
3 = a ⇒ a = 3
Using (1, 6), then
6 = 3 ⇒ b = 6 ÷ 3 = 2
The equation is y = 3
About 1407 sharks would be needed to have a margin of error of 0.25
<h3>What is margin of error?</h3>
Margin of error is used to determine by what value there is deviation from the real value. Margin of error (E) is given by:
The 90% confidence level have a z score of 1.645. Hence for E = 0.25, standard deviation = 5.7 feet, hence:

The solution is x = -5
Step-by-step explanation:
Given equation is:
In order to solve the eponnetial equations, we have to equate the bases of both sides so that the exponents can be put equal
So,
Replacing 9 with 3^2
When there are exponents on exponents, both are multiplied so,
As the bases on both sides are same, the exponents can be put equal
So,
Adding 1 on both sides
Subtracting 2x from both sides
Hence,
The solution is x = -5
