Hello,

Answer A: (-infini,3/2)
Vertex is (3/2,41/4) and the curve is turning its concavity down.
f'(x)=-2x+3=0==>x=3/2

Drag each shape to the correct location on the image. Not all shapes will be used. Complete each shape with the missing half so

Sav [38]

Answer:

see attached

Step-by-step explanation:

Perhaps the easiest way to do this is to draw the needed shape in the box, then locate it among the answer choices. Use the identifying features such as dot location and direction of arrow (or tail).

Left-to-right, this is what you're trying to match:

tail on the right, dot in the tail
tail on the left, dot in the fin
tail on the right, dot in the nose
tail on the left, dot in the center

a paper airplane can be made out of two different pieces of paper: a circular piece 10 inches wide and a square piece 11 inches

madreJ [45]

Compare the areas of the 2 different pieces of paper.

For the circle, the area is A=pi * r^2, which works out to A = pi(5 inches)^2.

For the square, the area is A = s^2, where is the side length, which here is 11 inches.

Finish these calculations, and then compare your two areas. Which is the larger?

1. Solve for the x and y intercepts:

aleksandrvk [35]

To find the x-intercept, you simply make y equal to 0 and solve the equation for x. To find the y-intercept, you make x equal to 0 and solve for y. So, for number 1, the answer is D because when you set it to y equals 0, you get x=3 and when you set it to x equals 0, you get 4.
Number 2 we would do the same thing and get D as well.
Hope this helps!
