Answer:
Step-by-step explanation:
Divide all three terms by 2 to isolate x:
|x + 5/2| > 0.25
Case 1: x + 5/2 > 0.25 (no absolute value symbol needed), or x > -2.25
Case 2: -(x + 5/2) > 0.25. Multiplying both sides by -1 yields
x + 5/2 < -0.25. Subtracting 5/2 from both sides: x < 5.45
The solution set is -2.25 < x < 5.45.
Answer: radius = 6.18 (I don't know what solutions you have, but the actual answer for the radius is about 6.18 cm so which ever is closest.)
Step-by-step explanation:
the area of a circle is \pi r^{2}
*rewrite your equation solving for radius
r=\sqrt{A/\pi } =\sqrt{120/\pi } = 6.18
Answer:
(3x-4)(x+4)
Step-by-step explanation:
What you do is look at the lass number. What 2 numbers can be multiplied together to get -16. That is 4.
You need to make sure that you need to get it to where subtracted it equals 8.
(3x-4)(x+4) is your answer.
Answer:
48 °
Step-by-step explanation:
The following data were obtained from the question:
Adjacent = 12 cm
Hypothenus = 18 cm
Angle R =?
We can obtain angle R by using cosine ratio. This can be obtained as follow:
Cos R = Adjacent / Hypothenus
Cos R = 12 / 18
Cos R = 0.6667
Take the inverse of Cos
R = Cos¯¹ 0.6667
R = 48 °
Thus, <QRP = 48 °
