Which of the following is a sinusoid? x^2+y^2=1 y=cosx or y=[x] or y=^3root x or y=cos x

y=cos x

Step-by-step explanation:

A sinusoid is a mathematical curve that describes a smooth periodic oscillation. Periodic means that the values and the shape of the function are repeated regularly. Sinusoid  is named after the function sine. The cosine function is just the sine function translated 90° to the left, so it's a sinusoid.

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser
