Look at the picture below. Sorry if its hard to understand.
First we write equation for perimeter of rectangle. Why? because we have been given that it is 128 units and maybe we can calculate something from it.
P = 2a + 2b where
a = 2(3y + 1 ) and b = 2(2y +3)
P = 6y + 2 + 4y + 6 = 10y + 8 = 128
now we can solve for y
10y = 120
y = 12
Now we just express value of y in formula for finding lenght of VW and we got length
Answer is 37
I think it is B because 4 times 4 is 16, and 1/2 of 4 is 2. 2 times 2 is 4.
Answer:
Solution : Option A
Step-by-step explanation:
Let' go through all the options we have here.
• x + 2 = - 1 / 8y² converted into standard form will be 4(- 2)(x - (- 2)) = (y - 0)². The parabola properties will be similar to the ones of this parabola, vertex = (- 2,0) and focal length = - 2. It hence is most likely to be the parabola provided to us.
• y = 1 / 8(x + 2)² is an up - down facing parabola, and hence is not at all similar to the given parabola
• x - 2 = 1 / 8y² will be a graph reflected over the y - axis with respect to the graph x + 2 = - 1 / 8y². It hence does not match the given parabola
• y = 1 / 8(x + 2)² will be a graph reflected over the x - axis with respect to the graph of y = 1 / 8(x + 2)². It will hence be a down - up facing parabola, which does not match the given parabola
