So we have a rectangle, whose area is A=bh. We don't know any of those, so we've got a bit of thinking to do. (Wish I could draw a picture....) First of all, we only need to consider half the rectangle. Since it is bounded by a parabola that is symmetric over the y-axis (ie not moved left or right), the rectangle has the same area on the right and left. So let's just consider the first quadrant. Note that if we maximize this area, we maximize the entire rectangle's area. The width of this half rectangle is x (it's the x coordinate). The height of this rectangle is whatever the y coordinate of the corner is. That corner is directly above the x coordinate, and is on the rectangle. So the upper corner must have coordinates of (x, y), or (x, 8-x2). Those will serve as our base and height. A = x (8 - x2)A = 8x - x3 Maximize implies derivative = 0, so... dA = 8 - 3x20 = 8 - 3x23x2 = 8x2 = 8/3x = ±1.633 Notice that this is giving us two answers -- one of them is on the left (second quadrant), while the other is on the right. The y coordinates will be the same for both, due to the nature of this parabola. y = 8 - (1.633)2y = 8 - (8/3)y = 5.333 Our upper corners are (±1.633, 5.333). The dimensions are: Height: 5.333Width = (2 · 1.633) = 3.266 :)
The first one is correct because the form is y-y1=m(x-x1)
Answer: v = 32 degrees
Step-by-step explanation:
The polygon theorem states that for any polygon with n sides, the sum of the interior angles is (n - 2) × 180
The given polygon has 6 sides. Therefore, n = 6
The sum of the angles in the polygon is
(6 - 2) × 180 = 3 × 180 = 540 degrees
Therefore,
119 + 134 + 108 + v + 47 + 2v + 2v - 28
Collecting like terms, it becomes
119 + 134 + 108 + 47 - 28 + v + 2v + 2v = 540
380 + 5v = 540
5v = 540 - 380
5v = 160
v = 160/5
v = 32 degrees
1/6 and 2/3 the LCD is 12 but the product of 6 and 3 is not 12
No, it is not. I will show you:
-1 = x and 2 = y
2 = -5(-1) + 7
2 is not equal to 12. I hope this is right!
