what is the area of the shaded region in the figure shown use 3.14 for the and round your answer to the nearest tenth
Step-by-step explanation:
Area Of rectangle = 9 ×5 = 135
Area Of Half The Circle = 0.5 ( 3.14 ) (r^ 2) = 0.5(3.14 (20.25) = 31.7925
Area Of Shaded = Area Of Rectangle
= Area of Half Circle = 135 - 317925 = 103.2

hey guys how do you simplify this fully?
Answer:

Step-by-step explanation:
In 100^1000,
100 can be written as,
100 = 10 x 10 = 10^2
100^1000
= 10^( 2 * 1000 )
= 10^2000
10 can be written as,
10 = 2 x 5
10^2000
= ( 2 x 5 )^2000
Formula : -
( a x b )^n = a^n x b^n
Here,
a = 2
b = 5
n = 2000
( 2 x 5 )^2000 = 2^2000 x 5^2000
[ 2^2005 x 5^2000 ] / 100^1000
= [ 2^2005 x 5^2000 ] / [ 2^2000 x 5^2000 ]
Formula : -
a^m x b^n / a^c x b^d
= a^( m - c ) x b^( n - d )
Here,
a = 2
m = 2005
c = 2000
b = 5
n = d = 2000
[ 2^2005 x 5^2000 ] / [ 2^2000 x 5^2000 ]
= 2^( 2005 - 2000 ) x 5^( 2000 - 2000 )
= 2^5 x 5^0
{ Note : Any number power 0 ( except 0 ) is 1.
That is 0^0 ≠ 1, but 5^0 = 1. }
= 2^5 x 1
= 2^5
= 2 x 2 x 2 x 2 x 2
= 32

by use fethagors on the 3 triangle and make 3 equation with 3 variable we can solve the question like in picture
The value of y for the given right-angle triangle is 8.
What is the Pythagorean theorem?Pythagorean theorem states that in the right angle triangle, the hypotenuse square is equal to the square of the sum of the other two sides. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.
Pythagorean theorem states that in the right angle triangle, the hypotenuse square is equal to the square of the sum of the other two sides.
Apply Pythagorean theorem with common y,
x² - 16² = z² - 16
x² - z² = 256 - 16 = 240
Again apply the Pythagorean theorem, In the whole triangle
x² + z² = 20²
x² + z² = 400
From the expressions,
2x² = 400 + 240
2x²² = 640
x² = 320
x = 17.88
Again by the Pythagorean theorem,
y² = x² - 16²
y² = 17.88² - 16²
y² = 320 - 256
y² = 64
y = 8
Hence, the value of y is 8.

An attorney charges a fixed fee on $250 for an initial meeting and $150 per hour for all hours worked after that. Write an equation in slope-intercept form. Find the charge for 26 hours of work.
Answer:
y=150x+250
Charge: $4,150
Step-by-step explanation:
Set the number of hours the attorney worked equal to x and the total amount of money he charges equal to y. If he charges 150 dollars an hour, then the amount of money he charges would be 150 dollars multiplied by the number of hours he worked. Thus, y=150x.
Next, it is known that the attorney also charges a fixed rate of 250 dollars for the initial meeting, so we have to add that to the amount of money he makes each hour, as it is a flat rate. Thus, y=150x+250.
Finally, if the attorney worked for 26 hours, we would then plug that number into the equation we created for x, the number of hours worked. Thus the total charge of the attorney would be $150 multiplied by 26 hours, $3900, and then adding the $250 flat rate for the initial meeting, for a grand total of $4,150.

The data set with mode 17 and median 16 is third data set.
What is Mode and Median?Mode of a data set is the value that occur most frequently in a data set.
Median of a data set is the element in the middle if the data are arranged in increasing or decreasing order.
Given are three data sets.
For the first one,
12, 12, 18, 13, 17, 15, 17, 17, 15
Mode = 17 [Since it is repeated most 3 times]
To find median, arrange in ascending order.
12, 12, 13, 15, 15, 17, 17, 17, 18
Three are 9 elements. The middle element is the 5th element.
Median = 15
For the second one,
20, 19, 17, 18, 16, 13, 12, 13, 11
Mode = 13 [ since it is repeated most, 2 times]
Arranging in ascending order,
11, 12, 13, 13, 16, 17, 18, 19, 20
Again the middle element is the 5th element.
Median = 16
Hence the correct option is third data set.

Different types of encoding affect a person’s ability to remember words. You can test this by asking a participant to first do a task involving either visual, auditory, or semantic encoding. Then ask the participant to recognize the encoded words. For example, for visual encoding, the participant may be asked to judge whether the word appears in all capital letters, whereas for auditory encoding, the participant may be asked to judge whether the word rhymes with another word.
A professor of cognitive psychology is interested in the percent accuracy on this memory encoding task among college students. She measures the percent accuracy for 49 randomly selected students. The professor knows that the distribution of scores is normal, but she does not know that the true average percent accuracy on this memory encoding task among college students is 0.794 percent correct with a standard deviation of 0.105 percent correct.
The computation of the data shows that the standard error is 0.015.
How to calculate the standard error?From the information, the following can be deduced:
Number of students n = 49
Randomly selected students = 0.794
The standard error will be:
= 0.105/✓49
= 0.105/7
= 0.015
In conclusion, the standard error is 0.015.

for each volunteer. The value of r for the scatterplot is
0.935.
Driving Reaction Times
How would the correlation change if the stopping
distances were recorded in meters, rather than feet?
O The value of the correlation coefficient would not
change.
O Since the points would be more spread out, the value
of the correlation coefficient would decrease.
O Since the number of meters would be less than the
number of feet, the value of the correlation coefficient
would increase.
© Since the number of meters would be less than the
number of feet, the value of the correlation coefficient
would decrease.
The value of the correlation coefficient remains the same when the unit is changed from feet to meters.
What is correlation coefficient?The term correlation coefficient is a measure of how much association there is between variables in a scatter plot. A high positive value of correlation coefficient means that there is a strong positive association between the variables and vice versa.

A mother is 33 years older than her twin children. In 3 years her age will be twice the combined ages of the twins. How old are the twins now?
9514 1404 393
Answer:
30
Step-by-step explanation:
Let m represent the mother's age in 3 years. At that point in time, her age is twice a twin's age, which is m-33:
m = 2(m -33)
m = 2m -66 . . . . eliminate parentheses
66 = m . . . . . . . . add 66-m
In 3 years, the mother's age will be 66. Each twin is now 36 years younger.
The twins are 30 years old now.
Given the parent function f(x)=|x|, write the equation of the function g(x) whose graph is pictured
F(x) =|x|g(x)
G(x)= ????
By analyzing the graph of the transformed function, we can see that:
g(x) = 2*|x - 2| - 4
How to get the function g(x)?
In the image we have two graphs, the yellow one is the graph of g(x).
First, analyzing the vertex we can see the translation used, you need to remember:
Horizontal translation:
For a general function f(x), a horizontal translation of N units is written as:
g(x) = f(x + N).
If N is positive, the shift is to the left.If N is negative, the shift is to the right.Vertical translation:
For a general function f(x), a vertical translation of N units is written as:
g(x) = f(x) + N.
If N is positive, the shift is upwards.If N is negative, the shift is downwards.We can see that the new vertex is at (2, -4), so the translation is 2 units to the right and 4 units down, then we have:
g(x) = |x - 2| - 4
Now, you also can see that the yellow function is narrower, such that for each increase in the x-unit, we have an increase of 2 in the y-axis, then we need to multiply by 2 the absolute value part:
g(x) = 2*|x - 2| - 4
This is the transformed function.
