Assume that when adults with smartphones are randomly selected, 51% use them in meetings and classes. if 9 adult smartphone users are randomly selected, find the probability that 6 of them use smartphones in meetings or classes.

no, x cannot be the same number. in all of them, x is 1. for one input there is another output. g is not a function

answer: 0+0=0

step-by-step explanation:

that is the only answer that can make 0

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
