Find the area of the shaded region. Round your answer to the nearest hundredth.
I need a detailed way to solve the solution.
Quick as possible!
Answer:
4.56
Step-by-step explanation:
i see a sector hosting 2 semi circles.
this sector area will be .25 of area of circle with radius 4ft.
area of sector = .25*π*16= 4π ft^2
area of semi circle of radius 2ft = .5π*4= 2πft^2
area of 2 semicircles = 4π
the total area of sector = area of 2 semicircles - intersection area + area not covered by semi circles
4π = 4π - intersection area+area not covered by semi circles
intersection area = area not covered by semi circles
now draw a square starting from the intersection point of 2 semi circles at their upper portion. the side will be 2ft
the area of intersection will be covered in the square.
area of intersection = 2*quarter area of circle of radius 2ft - area of square
= 2*(.25π4) - 4
2π-4 = 2.28
area of intersection = area not covered by semicircle
so area of shaded region = 4.56

A logarithmic function, h, is plotted on the graph. What is the approximate rate of change of this function on the interval [-2,2]?
Answer:
C: - 9/8
Step-by-step explanation:
interval: -2 ≤ x ≤ 2
Find 2 coordinate points on the graph where x = -2 and x = 2:
(-2, 2) and (2, -2.5)
Let [tex](x_1,y_1)[/tex] = (-2, 2) and [tex](x_2,y_2)[/tex] = (2, -2.5)
rate of change = [tex]\frac{y_2-y_1}{x_2-x_1}=\frac{-2.5-2}{2+2} =\frac{-4.5}{4}=-\frac{9}{8}[/tex]

What is Probability?This is the likelihood or chance that an event will occur.
Probability = Expected/Total
Given the following
Pr(rain) = 3/5Pr (lightening) = 2/5The probability of a sporting event being canceled due to rain or lightning = 3/5 * 2/5
The probability of a sporting event being canceled due to rain or lightning = 6/25

M is the midpoint of PQ. PM = 5x+8. PQ = 76. Find the value of x.
Answer:
x = 6
Step-by-step explanation:
Since M is the midpoint of PQ
PM = MQ = 1/2 PQ
5x+8 = 1/2(76)
5x+8 = 38
5x = 38-8=30
x = 30/5 = 6
Answer:
x = 6Step-by-step explanation:
First, let's revise a few definitions.
Definition of midpoint: The point that is in the middle of a line.We know that:
M is the midpoint of PQPM = 5x + 8PQ = 762PM = PQWork:
2PM = PQ=> 2(5x + 8) = 76=> 10x + 16 = 76=> 10x = 76 - 16=> 10x = 60=> x = 6Hence, the value of x is 6 units.

−2.7(x−1.4)=−6.48
Enter your answer, as a decimal, in the box.
Answer:
x = 3.8
Explanation:
−2.7 (x−1.4)=−6.48
(−2.7)x + (−2.7)(−1.4) = −6.48
−2.7x+3.78= −6.48
-2.7x = −6.48 - 3.78 ....changing sides, turns + integer to -

The temperature was -20 degrees in Alaska and 85 degrees in Hawaii. What is the difference
between the two temperatures?
(HELP)
Answer:
The difference in temperature is 105 degrees.
Step-by-step explanation:
The difference in temperature is 105 degrees because it's -20 in Alaska and 85 in Hawaii. When calculating the difference in temperature, negative numbers are still added to the sum total. so 85 + 20 = 105.
Using the Classic Rock data in the Math 108 group on StatCrunch, create a histogram with the
variable PlayCount. When creating the histogram, check the box that says Value above bar and also check the Mean box. Answer the
following questions about the histogram. Recall that
there are 1651 songs played.
1. What percent of songs were played over 100 times?
1% (round to the nearest whole integer)
2. What is the mean?
songs (round to the nearest whole integer)
3. What percent of songs were played less than 20 times?
% (round to the nearest whole integer)
The product of the frequency and PlayCount gives the number of songs
played from the information in the histogram.
Correct responses (rounded to the nearest whole integer)
1. 2%
2. 27 PlayCount per song
3. 68%
How does one analyze an histogram?1. The given data from the histogram is presented in a tabular form as follows;
[tex]\begin{tabular}{|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|}f&899&224&126&96&71&52&39&41&44&23&14&12&3&4&3\\x&10&20&30&40&50&60&70&80&90&100&110&120&130&140&150\end{array}\right][/tex]
The percentages of song that where played over 100 times is given as follows;
∑f = 899+224+126+96+71+52+39+41+44+23+14+12+3+4+3 = 1651
Number of songs played over 100 times = 14 + 12 + 3 + 4 + 3 = 36
[tex]Percentage \ of \ songs \ played \ over \ 100 \ times = \mathbf{\dfrac{36}{1,651} \times 100} \approx \underline{2 \%}[/tex]2. Mean of a frequency distribution is given as follows;
[tex]Mean = \mathbf{\dfrac{\sum f\times x}{\sum f}}[/tex]
Where;
x = The PlayCount
From MS Excel, we have;
∑f·x = 44410
Which gives;
[tex]Mean = \dfrac{44410}{1651} \approx \underline{27}[/tex]3. Number of songs played less than 20 times = 899 + 224 = 1,123

A mother is three times as old as her daughter,in twelve years time she will be twice as old.How old is the mother now ?
Answer:
its 48 i can explain how i got the answer if you would like
Step-by-step explanation:
Find the value of x.
the sum of all interior angles in a polygon is
180( n - 2)
n = number of sides
now, this polygon is a quadrilateral, so it has 4 sides, so it's total is just 180( 4 - 2) = 360.
[tex]360=x+4x+3x+2x\implies 360=10x\implies \cfrac{360}{10}=x\implies 36=x[/tex]
Answer:
x = 36
Step-by-step explanation:
The angles of a trapezoid add up to 360, so add x, 4x, 3x, 2x to get 10x
10x = 360
360/10 = 36
Therefore, x = 36
