After having been on the air for more than a decade, Fox's American Idol seemed to be suffering from viewer fatigue. The average

mixas84 [53]

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:

$f(t) = 32.744*e^{-0.252t}$ (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,

$f(1) = 32.744*e^{-0.252*1}$

=25.45 million viewers

(b) In the 2014 season, when =4

$f(4) = 32.744*e^{-0.252*4}$

=11.95 million viewers

assuming that the trend continued into that season

If x is a positive integer, for how many different values of x is StartRoot StartFraction 48 Over x EndFraction EndRoot a whole

DiKsa [7]

Answer:

For 3 different values of x

Step-by-step explanation:

Here, we want to get the values of x for which

√(48/x) is a whole number

We have to consider that the values of x that will make the expression a whole number must be less than or equal to 48

Also, we have to consider that, the division we have to make must yield a perfect square so as to have a whole number square root

The factors of 48 that can yield a whole number are;

1,2,3,4,6,8,12,16,24 and 48

However, the divisions that can yield a perfect square are

3 (yield 16)

12 ( yield 4)

48 ( yield 1)

So the numbers of the value of x that can yield a whole number is 3

The area of a rectangular field is 2275 m2. The field is enclosed by 200 m of fence. What are the dimensions of the field?

AURORKA [14]

So it is enclosed by 200 m of fence
perimiter=200 m
it is a rectangle to
p=legnth+legnth+width+width or
p=l+l+w+w or
p=2l+2w or
p=2(l+w)
so
p=200
200=2(l+w)
divide both sides by 2
100=l+w
area=l times w
area=2275
lw=2275
l+w=100
combine and solve
l+w=100
subtract w
l=100-w
subisutute 100-w for l in other eqution
(100-w)(w)=2275
distribute
-w^2+100w=2275
add (w^2-100w) to both sides
0=w^2-100w+2275
factor
find what 2 numbers add up to -100 and multiply to get 2275
guess (or factor 2275 and find factors that add up to -100)
figure out that they are -65 and -35
0=(w-65)(w-35)
set each to zero
0=w-65
0=w-35

solve for w
w=65 or 35
65>35 so
65 m=legnth
35 m=width
