The quadratic formula is x= -b +/- √b²-4ac / 2a
In this problem,
a=6
b=4
c=-3
Now, we can plug this into the formula:
x= -4 +/- √4²-(4)(6)(-3) / (2)(6)
x= -4 +/- √16+72 / 12
x= -4 +/- √88 /12
x= -4 +/- 2√22 /12
x= -2 +/- √22 / 6
So,
x= -2 + √22 / 6
x= -2 - √22 / 6
I don't know what your choices are, but I did the questions for you.
R=D/2, R=12, R=radius,
SA= 4 times 3.14 12 times 12, so,
SA=1809.557368, if you round it to two decimal places, it'll be,
1809.56, so the answer is 1809.56in. squared.
Answer:
315
Step-by-step explanation:
We are told in the question that each fret marker is in the shape of a parallelogram
The area of a parallelogram is given as
Base × Height.
Each of the bottoms of the fret markers has the following values
Base = 52.5mm
Height =6 mm
The area of each of the bottom fret markers
= Base × Height
= 52.5 × 6
= 315
Therefore, the area of each of the bottom fret markers without unit is 315
