Answer:
C
Step-by-step explanation:
We want to determine the vertex of the quadratic equation:

Recall that the vertex is given by the formulas:

In this case, <em>a</em> = -1, <em>b</em> = 2, and <em>c</em> = 1.
Determine the <em>x-</em>coordinate of the vertex:

To determine the <em>y-</em>coordinate, evaluate the function at <em>x</em> = 1:

In conclusion, the vertex of the quadratic equation is (1, 2).
Hence, our answer is C.
2/4=1/2 and 4/8
1/3=2/6 and 3/9
1/4=2/8 and 3/12
Multiply the two numbers to find the amount of the loan.
5530/1* 4/7= 22120/7= 3160
Final answer: $3,160
Answer:
A = 22.62
Step-by-step explanation:
Remember law of tan
tan = opposite/adjacent
tan (A) = 5/12
A= tan inverse ( 5/12)
A = 22.62
