Which interval for the graphed function contains the local maximum?
a. [-1,0]
b.[1,2]
c. [2,3]
d. [3,4]
HELP ASAP

A. (-1,0)

Step-by-step explanation:

You check to see if the line goes through the coordinates.

The line does not go through (1,2), which is 1 unit right and (in this case) 1 unit up from the coordinate plane.

The line does not go through (2,3), which is 2 units right and (in this case) 1.5 units up from the coordinate plane.

The line does not go through (3,4), which is 3 units right and (in this case) 2 units up from the coordinate plane.

The line does go through (-1,0), though.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
