The answer is (1) x=-2. The property of the equation like y=ax2+bx+c is that the axis of symmetry of the graph is x=-b/2a. So for this question, the axis is x=-4/2=-2.
122 divided by 3.14 is 38.9.
38.9 divided by 13 is 2.9 = 3 hours
If you round 100.360 to the nearest whole number it'll be (100) if you see "100.500" i'll be 101 due to the decimals
Answer:
<u>C. 4</u>
Step-by-step explanation:
Using the Law of Sines,
<u>Here,</u>
- A = 63°
- a = x + 8
- B = 63°
- b = 3x
<u>Solving</u> :
- sin63°/x + 8 = sin63°/3x
- x + 8 = 3x
- 2x = 8
- x = 4
