<span>Simplifying
4x2 + 8xy + 4y2
Reorder the terms:
8xy + 4x2 + 4y2
Factor out the Greatest Common Factor (GCF), '4'.
4(2xy + x2 + y2)
Factor a trinomial.
4((x + y)(x + y))
Final result:
4(x + y)(x + y)</span>
Answer:
a) $50,880
b) $48
c) 1060
Step-by-step explanation:
a)
-320x^2 + 1920x + 48000 = 0
This is a parabola that opens downward. It has a maximum value. The maximum value occurs at x = -b/(2a)
x = -b/(2a) = (-1920)/(2(-320)) = 1920/640 = 3
The maximum revenue, y, is the value of the function evaluated at x = 3.
f(x) = -320x^2 + 1920x + 48000
f(-3) = -320(3)^2 + 1920(3) + 48000
f(-3) = 50,880
The maximum revenue is $50,880
b)
Since maximum revenue occurs at x = 3, and since x represents the number of $4 discounts, the discount is 3 * $4 = $12. The price is $60 - $12 = $48
c)
$50,880/$48 = 1060
In trigonometry, the trigonometric ratios are used to determine the value of the trigonometric functions of the angles of a right triangle.
The trigonometric ratios is commonly called SOH-CAH-TOA, according to the formulas used to obtain then.
Given a right triangle with angles A, B and C and sides 17, 8 and 15.
Since, the denominator of the given ratio is 15, which is not the hypothenuse (the slant side), thus, the trigonometric function is neither sin nor cos but tan, thus we look for the angle which the side of length 15 is the adjacent side. The required angle is B.
Therefore, 8/15 represent tan B.
