Answer:
The leverage of an observation is determined by how far the values of the independent variables are from their means.
Sin 35 = x/15
x = sin 35*15
x = 8.6 cm
B= -2x+5-2x^2-ax
A= -2x+5-2x^2-b/x
x=0
The area of a circular sector is <span>. </span>
<span>==> </span>
<span>Since r = s/2, it follows that </span><span>, or </span><span>, or </span>
<span>.
</span>
(A)
Choice (B) is not the right answer because I
it's only 3rd order. But because f(x) goes to negative infinity when x goes to positive infinity means that the right answer is (A).
