Step-by-step explanation:
Problem 1
g(-23) = 3
g(0) = 5
2 = g(10)
1 = g(34)
Problem 2
No, because g(x) = f(-x). For g(x) to inverse of f(x), g(f(x)) = x
Problem 3
tan(50) = 1.19
Height of statue = 250*1.19 - 150
= 147.9 ft
Problem 4
cosθ = 9/12
θ = 41.41 deg.
Answer:
Step-by-step explanation:
g(x) is inverse of f(x)
so g(f(x))=x
g(-23)=3
g(0)=5
g(10)=2
g((34)=1
no, it is an inverse
4 inverse fn, g(r(x))=x
but here g(x)=r(-x)
so g(r(x))=r(-r(x)) n NOT =x
pedestal + statue = 250*tan(50degree) = 297.94
statue ht = 297.94-150 = 147.94 ft
cos(theta) = 9/12
theta = 41.41 deg.
Omar, Hala and Lujain got paid a total of $240 for cleaning neighborhood cars. They split the money in the ratio of 5: 9: 10. How much money did Omar earn?
Answers
Answer:
Total amount Omar earn = $120
Step-by-step explanation:
Given:
Total amount Omar, Hala and Lujain got paid = $240
Ratio of money Omar, Hala and Lujain got paid = 5:9:10
Find:
Total amount Omar earn
Computation:
Total amount Omar earn = [Total amount Omar, Hala and Lujain got paid][Omar'ratio / Total ratio]
Total amount Omar earn = [240][5 / (5+9+10)]
Total amount Omar earn = [240][5 / (24)]
Total amount Omar earn = [24][5]
Total amount Omar earn = $120

A comedy club hosts an amateur comedy night, a good opportunity for aspiring comedians to
perform. Of the 8 amateur comedians who signed up for tonight's show, 6 perform satirical
comedy,
If the host randomly selects 4 comedians from the sign-up list, what is the probability that all
of them practice satirical?
Write your answer as a decimal rounded to four decimal places.
Answers
Answer:
0.2143 probability that all of them practice satirical.
Step-by-step explanation:
The comedians are chosen without replacement, which means that the hypergeometric distribution is used to solve this question.
Hypergeometric distribution:
The probability of x sucesses is given by the following formula:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]
In which:
x is the number of sucesses.
N is the size of the population.
n is the size of the sample.
k is the total number of desired outcomes.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
In this question:
8 comedians means that [tex]N = 8[/tex]
6 practice satirical means that [tex]k = 6[/tex]
Sample of 4 means that [tex]n = 4[/tex]
What is the probability that all of them practice satirical?
This is P(X = 4). So
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]
[tex]P(X = 4) = h(4,8,4,6) = \frac{C_{6,4}*C_{2,0}}{C_{8,4}} = 0.2143[/tex]
0.2143 probability that all of them practice satirical.

Answer:

Step-by-step explanation:
Sum the terms (x - 2) for x = 2 to 5 then square the result
[ (2 - 2) + (3 - 2) + (4 - 2) + (5 - 2) ]²
= ( 0 + 1 + 2 + 3 )²

S'. Which relationship between S' and S must be true?
A. S’ is the same point as S.
B. S’ is S reflected about the y-axis.
C. S’ is S reflected about the line y= -x
D. S’ is the result of switching coordinates of S.
Answers
Answer:
D. S’ is the result of switching coordinates of S.
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Type of transformation are translation, reflection, rotation and dilation.
If a point A(x, y) is reflected along the x axis, the new point is A'(x, -y). If a point A(x, y) is rotated 90° counterclockwise about the origin, the new point is A'(-y, x).
Let us assume that S is at (x, y). Hence, if point S is reflected about the x-axis in the coordinate plane to get (x, -y). If it is then rotated 90° counterclockwise about the origin, the new point is at S'(y, x). S’ is the result of switching coordinates of S
Find the probability of rolling a number less
than 3 on a die.
Pls help
Answers
Step-by-step explanation:
When a die is rolled, here it's Total possible outcome is= 6
and sample space is = 2 ( i.e. 1 & 2)
So. Probability of getting less than 3 = 26
=13
That's it
Probability is always the how many over the total. In a die there are 6 chances. And to get less than 3 is only 2 chances. So the fraction is 2/6. Now if you want to find the percent you would have to divide 2 by 6. That will get you 0.333. If you round and make it into a percent that would be 33%.

16. A roller rink floor is show below. Each end has a semicircle. What is the area? Use = 3.14
20 m
Answers
Answer:
714m^2
Step-by-step explanation:
So, as we said in the comments, since they didn't give the radius, we have to assume the center is a square. That means the area of the center part is 20m x 20m, and the diameter of the circular ends is 20m as well.
Area of center: 20 x 20 = 400m^2
Area of ends:
Area = (pi)(r)^2
The radius = 1/2 the diameter = 10m
Area = (3.14)(10)(10)
Area = 3.14 x 100 = 314m^2
Now, if it only had one semicircle on the end like your previous question, we'd have to divide this answer by 2, but the circular area we just calculated covers both ends, so the total area = the square center + the circular area
400 + 314 = 714m^2

The Rational Root Theorem says that any rational root has

2. a denominator that is a factor of the leading coefficient (that's attached to the highest-power term)
Numerator: [tex]\pm 1[/tex]
Denominator: [tex]\pm 2[/tex]
That means there are only two possible rational roots: [tex]\pm \frac{1}{2}[/tex]
Try them both by plugging them into the polynomial.
