After having been on the air for more than a decade, Fox's American Idol seemed to be suffering from viewer fatigue. The average
1 answer:
Answer:
(a)25.45 million viewers
(b) 11.95 million viewers
Step-by-step explanation:
The average number of viewers from the 2011 season through the 2013 season is approximated by the function:
(1 ≤ t ≤ 4) where f(t) is measured in millions.
t = 1 corresponds to the 2011 season.
(a) In 2011, t=1
Average number of viewers in the 2011 season,
=25.45 million viewers
(b) In the 2014 season, when =4
=11.95 million viewers
assuming that the trend continued into that season

c)
So then the heigth for the building is approximately 30 ft
Step-by-step explanation:
Part a
We can see the figure attached is a illustration for the problem on this case.
Part b
For this case we can use the sin law to find the value of r first like this:
Then we can use the same law in order to find the valueof x liek this:
And that represent the distance between Sara and Paul.
Part c
For this cas we are interested on the height h on the figure attached. We can use the sine indentity in order to find it.
And if we solve for h we got:
So then the heigth for the building is approximately 30 ft
Answer:
sinΘ =
Step-by-step explanation:
using the identity
sin²x + cos²x = 1 ( subtract cos²x from both sides )
sin²x = 1 - cos²x ( take square root of both sides )
sinx = ±
given
cosΘ = - , then
sinΘ = ±
= ±
= ±
= ±
since Θ is in quadrant II where sinΘ > 0 , then
sinΘ =
