The number of hours, H, of daylight in Madrid as a function of date is approximated by the formula H=12+2.4sin(0.0172(t−80)),
where t is the number of days since the start of the year. (We can think of t=0 as the stroke of midnight on Dec. 31/Jan 1; thus, January falls between t=0 and t=31, February falls between t=31 and t=59, etc.).

Find the average number of hours of daylight in Madrid (assuming in each case that it is not a leap year):

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,

only 10/60 isn't equivalent

hope this : )

false

step-by-step explanation:

the meaning of changing is to edit or make something different.

but transmitting means cause (something) to pass on from one place or person to another.
