Interest = PRT /100
500 = 2000*2.5*T / 100
5000T = 50,000
T = 50,000 / 5000 = 10 years

To convert to an equation introduce k, the constant of variation.
y
=

Step-by-step explanation: Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
Cos Q = 16/65
Step-by-step explanation:
In this question, we have a triangle and we have the information above supplied. We are being tasked with getting the ratio of the cosine.
To do this, we shall be making reference to a diagrammatic representation of the information supplied. Please do check the attachment section for this.
Looking at this triangle, we can see that one of the angles measure 90, what this means is that what we are dealing with is a right-angled triangle.
Now to get the answer in the question, we have to define what is meant by the cosine. The cosine is a trigonometric ratio of the adjacent to the hypotenuse.
In this case, our adjacent is 16 while our hypotenuse is the longest side which is 65.
Hence, Cos Q = 16/65
