Which function is graphed below?

On a coordinate plane, a curve goes has a maximum point at 1 and a minimum point at negative 1. It crosses the y-axis at (0, 1) and increases through the y-axis.
f(x) = cos(x)
f(x) = –cos(x)
f(x) = sin(x)
f(x) = –sin(x)

6 spoons of sugar for every 21 cups of flour

step-by-step explanation:

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5

answer: median

step-by-step explanation:

the median is the middle value when a data set is ordered from least to greatest

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
