The amount of interest after 3 years will be $15.
The complete question is given below.
You loaned a friend $100 and will charge him 5% annual simple interest when he pay it back. What is the amount of interest after 3 years?
<h3>What is simple interest?</h3>
Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on.
The interest is given as
I = (P × R × T) / 100
Where, P is the initial amount, R is simple interest rate, and T is the time.
We have
P = $100
R = 5%
T = 3 years
Then the interest will be
I = (100 × 5 × 3) / 100
I = $15

Answer: 80 miles
Step-by-step explanation:
The graphed polynomial seems to have a degree of 2, so the degree can be 4 and not 5.
<h3>
Could the graphed function have a degree 4?</h3>
For a polynomial of degree N, we have (N - 1) changes of curvature.
This means that a quadratic function (degree 2) has only one change (like in the graph).
Then for a cubic function (degree 3) there are two, and so on.
So. a polynomial of degree 4 should have 3 changes. Naturally, if the coefficients of the powers 4 and 3 are really small, the function will behave like a quadratic for smaller values of x, but for larger values of x the terms of higher power will affect more, while here we only see that as x grows, the arms of the graph only go upwards (we don't know what happens after).
Then we can write:
y = a*x^4 + c*x^2 + d
That is a polynomial of degree 4, but if we choose x^2 = u
y = a*u^2 + c*u + d
So it is equivalent to a quadratic polynomial.
Then the graph can represent a function of degree 4 (but not 5, as we can't perform the same trick with an odd power).

Answer:
4 - 1 - 3 - 2
Step-by-step explanation:
4 - Hydrogen enters the plant as part of water.
1 - Water is broken down into oxygen and hydrogen.
3 - Hydrogen combines with carbon dioxide to form glucose.
2 - Glucose is broken down to be used by plants.
During the process of photosynthesis, water and carbondioxide combined in the presence of sunlight to give rise to glucose which is then broken down to be used by plants. This is the process by which plants manufacture their food. Water is made up of hydrogen and oxygen. The hydrogen combines with CO2 to produce sugar for the plants.
