O The function is increasing for all real values of x
where
X<-1 and where x > 4.
O The function is decreasing for all real values of x
where
-1 < x <4
O The function is decreasing for all real values of x
where
x < 1.5.

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,

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

it would be a on edgenuit y

the diagram below is your final answer

93-8=85

855=17

17*4=68

there are 68 purple marbles in that bag
