Question
5! + 50
Step-by-step explanation:
about factorial
5!
=5 × 4 × 3 × 2 × 1
=20 × 3 × 2 × 1
=60 × 2 × 1
=120 × 1
=120
the result of the factorial 5! is 120
now we just add 120+50
120 + 50
120
50
———+
170
so the result of 5! + 50 is 170

A ball is placed in a machine that throws the ball up in the air. The table represents some points on the graph of a function that models the ball’s distance from the ground with respect to the time since the ball has been thrown. What is the range for this situation? A. All real numbers less than or equal to 7.66 B. All real numbers less than or equal to 1.25 C. All real numbers greater than or equal to 0 and less than or equal to 7.66 D. All real numbers greater than or equal to 0 and less than or equal to 1.25
Using it's concept, it is found that the range for this situation is given by:
C. All real numbers greater than or equal to 0 and less than or equal to 7.66.
What is the range of a function?
The range of a function is the set that contains all possible output values.
In this problem, the output values are the height of the ball, which researching the problem on the internet, is represented by a table in which the minimum height is of 0(when it hits the ground) and the maximum height is of 7.66 feet, hence the correct option is:
C. All real numbers greater than or equal to 0 and less than or equal to 7.66.

integral of x/(x + 1)²(x+2)²
I suppose you mean the integral
[tex]\displaystyle \int \frac{x}{(x+1)^2 (x+2)^2} \, dx[/tex]
Break up the integrand into partial fractions:
[tex]\dfrac{x}{(x+1)^2 (x+2)^2} = \dfrac{a}{x+1} + \dfrac{b}{(x+1)^2} + \dfrac{c}{x+2} + \dfrac{d}{(x+2)^2}[/tex]
[tex]\dfrac{x}{(x+1)^2 (x+2)^2} \\ = \dfrac{a(x+1)(x+2)^2 + b(x+2)^2 + c(x+1)^2(x+2) + d(x+1)^2}{(x+1)^2 (x+2)^2}[/tex]
[tex]\dfrac{x}{(x+1)^2 (x+2)^2} \\ = \dfrac{(a+c)x^3+(5a+b+4c+d)x^2+(8a+4b+5c+2d)x + 4a+4b+2c+d}{(x+1)^2(x+2)^2}[/tex]
[tex]x = (a+c)x^3+(5a+b+4c+d)x^2+(8a+4b+5c+2d)x + 4a+4b+2c+d[/tex]
Solve for the coefficients:
[tex]\begin{cases}a+c=0 \\ 5a+b+4c+d=0 \\ 8a+4b+5c+2d=1 \\ 4a+4b+2c+d=0\end{cases} \implies a=3,b=-1,c=-3,d=-2[/tex]
So we have
[tex]\displaystyle \int \frac{x}{(x+1)^2 (x+2)^2} \, dx= \int \left(\frac3{x+1} - \frac1{(x+1)^2} - \frac3{x+2} - \frac2{(x+2)^2}\right) \, dx[/tex]
[tex]\displaystyle \int \frac{x}{(x+1)^2 (x+2)^2} \, dx= 3\ln|x+1| + \frac1{x+1} - 3\ln|x+2| + \frac2{x+2} + C[/tex]
[tex]\displaystyle \int \frac{x}{(x+1)^2 (x+2)^2} \, dx= \ln|x+1|^3 - \ln|x+2|^3 + \frac{3x+4}{(x+1)(x+2)} + C[/tex]
[tex]\displaystyle \int \frac{x}{(x+1)^2 (x+2)^2} \, dx= \boxed{\ln\left|\frac{x+1}{x+2}\right|^3 + \frac{3x+4}{(x+1)(x+2)} + C}[/tex]

two number cubes are rolled. what is the probability of getting a 1 and a 4 in either order
Answer:
1/18
Step-by-step explanation:
Each cube can have 6 outcomes, from 1 to 6.
6 × 6 = 36
The total number of outcomes is 36.
The desired outcomes are only 1, 4 and 4, 1.
There are only 2 desired outcomes.
p(1, 4 or 4, 1) = 2/36 = 1/18

Suppose you have a bag with 25 letter tiles in it and 7 of the tiles are the letter V. If you pick a letter tile at random from the bag, the probability that it is the letter V is 7/25
. Suppose another bag has 500 letter tiles in it and 250 of the tiles are the letter V. Write the probability of picking a tile that is the letter V as a fraction and as a percent. From which bag are you more likely to pick a tile that is the letter V?
So
[tex]\\ \rm\hookrightarrow P(E)=\dfrac{|E|}{|S|}[/tex]
[tex]\\ \rm\hookrightarrow P(E)=250/500=1/2=0.5[/tex]
7/25=0.3Second bag is more preferable
Answer:
Bag 1
Probability of picking a V = P(V) = 7/25 = 0.28
Bag 2
Probability of picking a V = P(V) = 250/500 = 1/2 = 0.5
You are more likely to pick a tile that is the letter V from Bag 2 since 0.5 > 0.28

Step-by-step explanation:
[tex]\mathsf{area\ of \ sector=\dfrac{\theta\pi r^2}{360} \ (where\ \theta \ is \ measured \ in \ degrees)}[/tex]
Given:
r = 5[tex]\theta[/tex] = 80°[tex]\implies \mathsf{area\ of \ sector=\dfrac{80 \cdot\pi\cdot 5^2}{360}=\dfrac{50}{9}\pi \ cm^2}[/tex]
[tex]\mathsf{area\ of \ triangle=\dfrac12 ab\sin C}[/tex]
Given:
a = 5b = 5C = 80°[tex]\implies \mathsf{area\ of \ triangle=\dfrac12 \cdot 5 \cdot 5\sin (80)=\dfrac{25}{2}\sin(80) \ cm^2}[/tex]
Area of shaded area = area of sector - area of triangle
[tex]\implies \mathsf{area=\dfrac{50}{9}\pi-\dfrac{25}{2}\sin(80)}[/tex]
Therefore, area = 5.1 cm² (nearest tenth)

It will take her 5 5/8 hours to read 3/4 of the book
Ratio and proportions
Given that Elisabeth reads 1/5 of her book in 1 1/2 hours, this is expessed as:
0.2 of a book = 1.5 hours
In order to determine the time taken to read 0.75 part of the book, we will have:
0.75 of a book = x
Take the ratios
0.2/0.75 = 1.5/x
0.2x = 1.125
x = 1.125/0.2
x = 5.625

9. Which of the following is an equilateral triangle?
Answer:
d
Step-by-step explanation:
The dashes on the sides of the triangles mean that they are equal in length.
Isosceles triangle: 2 sides of equal length
Equilateral triangle: 3 sides of equal length
Triangle a doesn't have any dashes, so all the sides are different length.
Triangle b has 2 sides that each have the same number of dashes, so these sides are equal in length → Isosceles triangle
Triangle c has 2 sides that each have the same number of dashes, so these sides are equal in length → Isosceles triangle
Triangle d has 3 sides that each have the same number of dashes, so these sides are equal in length → Equilateral triangle

What is the amplitude of this function f(x) ?
f(x)=34cos(3x)+4
Enter your answer in the box.
The comparison between the standard form of the cosine and f(x)=34cos(3x)+4 shows that the amplitude of the function given is 34.
Cosine Functions
The standard form of the cosine is given by:
y=acos(bx+c)+d
where:
a= amplitude - half the distance between the maximum and minimum values of the function. The value of a will be |a|.
b= the number of cycles the function completes in an interval of from 0 to 2π. This parameter influences in the period since is [tex]\frac{2\pi }{b}[/tex].
c= horizontal shift
d= vertical shift
The question asks the value of amplitude. Therefore, you should compare the standard form with equation function given.
Thus, you have:
y=acos(bx+c)+d
f(x)=34cos(3x)+4
The comparison shows: a=34, b=3, c=0 and d=4
Hence, the amplitude of the function f(x)=34cos(3x)+4 is equal to 34.

Question 1
Which statement describes the basis for the proof that vertical angles are congruent?
А
Two adjacent angles are always supplementary
B.
Two adjacent angles that form a linear pair are congruent.
с
Two angles that are each supplementary to a third angle are congruent.
D
Two angles that are each complementary to a third angle are congruent.
Answer:
C
Step-by-step explanation:
On each linear pair, there is one of the Vertical angles and an angle shared between the two angles. This means we can use the fact that supplements of the same angle are congruent.
The basis for the proof vertical angles are congruent is " two angles that are each supplementary to a third angle are congruent".
What are vertical angles?Vertical angles are a pair of non-adjacent angles formed by the intersection of two straight lines.
In the provided figure.
∠1 + ∠2 = 180 degrees ( linear pair of angles)...(i)
∠ 1 + ∠4 = 180 degrees ( linear pair of angles)...(ii)
According to transitive property, if a = b and b = c then a = c
Therefore,
∠1 + ∠2 = ∠1 + ∠4...(iii)
⇒∠2 = ∠4
Similarly, we can prove that
∠1 = ∠3
Therefore, we conclude that vertically opposite angles are always equal.
Hence, the basis for the proof vertical angles are congruent is " two angles that are each supplementary to a third angle are congruent".
Thus, statement c is correct.
