Answer:
The line of symmetry is t = 3/2
Step-by-step explanation:
To find the line of symmetry, we use the equation given to find it using a quadratic.
-b/2a
In this equation, a is equal to the coefficient of t^2 and b is the coefficient of t.
-(48)/2(-16)
-48/-32
3/2
Step 1
Given;
Required; To find the difference in interest between the two periods.
Step 2
State the formula for simple interest
Step 3
Find the interest when the rate is 8%
Therefore the interest is given as;
Step 4
Find the interest in 1980 with a 20% rate
The interest is given as;
Step 5
Find the difference in interest between the two rates.
Hence, the difference in interest between the two rates = $11095.89
Correct Option is:

Explanation:</h2><h2 />
Two quantities are proportional if we can write one of them as k times the other. In other words, if x and y represents quantities, then if they stands for a proportional relationship we can write:
In whose case, we will have a linear function with slope k and that passes through the origin. From the options, the only one that matches our definition is Option D.
