Given quadratic equation
Using the usual conventions,
a=1, b=6, c=6
Apply the quadratic formula,
substitute a,b & c with numerical values,
simplify:
Answer:
Step-by-step explanation:
Triangle XYZ is a right angle triangle.
From the given right angle triangle
XZ represents the hypotenuse of the right angle triangle.
With ∠34 as the reference angle,
YZ represents the adjacent side of the right angle triangle.
XY represents the opposite side of the right angle triangle.
To determine x, we would apply the Cosine trigonometric ratio
Cos θ = opposite side/hypotenuse. Therefore,
Cos 34 = x/28
x = 28Cos34 = 28 × 0.8290
x = 23.212
To the nearest tenth, it becomes
23.2
Take $438÷4=109.5 take 184-109.5=74.5. Then 74.5×4=298. The correct answer is C.
The answer would be 0.34. Theres 77 humans out of 221 beings, which means 77/221. Simplifying this fraction gives us 0.34.
