Suppose f(x)=x^3 find the graph of f(x)+2

Answer:

x = 14

Step-by-step explanation:

1/2(x - 4) = 5                     - Given

1/2x - (1/2 * 4) = 5             - Distribute

1/2x - 2 = 5                       - Multiply 1/2 by 4

1/2x = 7                             - Add 2 to both sides of the equation

x = 14                                 - Divide both sides of the equal by 1/2

Answer:

Elga is 30 and Alvin is 15

Step-by-step explanation:

45-15=30

30-15=15

30+15=45

Answer:

[tex]\huge\boxed{\text{Alvin = 15, Elga = 30}}[/tex]

Step-by-step explanation:

In order to find Alvin and Elgas age, we can use a system of equations.

Let us assume that [tex]a[/tex] represents Alvin's age and [tex]e[/tex] represents Elgas age.

We can create two equations:

[tex]a = e-15[/tex]

[tex]a+e=45[/tex]

We can now use substitution to find each value. Let's substitute [tex]a = e-15[/tex] into [tex]a+e=45[/tex] as a.

[tex](e - 15) + e = 45[/tex]

We can now simplify this equation and solve for e.

[tex]2e-15 = 45\\2e = 60\\e = 30[/tex]

So we know that Elga is 30 years old. To find Alvin's age, we can substitute the value of e (30) back into one of the equations. Let's do it for [tex]a+e=45[/tex].

[tex]a + 30 = 45\\a = 45-30\\a=15[/tex]

So Elga is 30 years old and Alvin is 15 years old.

Answer:

22,080 tacos

Step-by-step explanation:

13,180 - 7,480 = 5700

5700 - 2500 = 3200

13,180 + 5700 + 3200 = 22,080

Answer:

60

Step-by-step explanation:

The number is represented as x.

81 is added to a number is

81 + x

39 less than three times the number

3x - 39

So

81 + x = 3x - 39

Solve for x.

81 + x = 3x - 39 Add 39 to each side so 39 cancels on the right.

81 + x + 39 = 3x - 39 + 39

81 + x + 39 = 3x

81 + 39 + x = 3x

120 + x = 3x Subtract x from each side.

120 + x - x = 3x - x

120 = 3x - x

120 = 2x    Divide each side by 2

120/2 = 2x/2

120/2 = x

60 = x

Answer:

There are 12 adults.

4 like oatmeal cookies the best.

P(exactly 4) = 4/12 = 1/3 = 0.3333...

B)

At least 4

So there are 9 choices (4 .. 12) of those who could like oatmeal cookies the best.

P(9) = 9/12 = 0.75

C)

There are at most 3 people who could like oatmeal cookies the best.

P(<4) = 3/12 = 0.25

Jan's starting number was 10.

A number is an arithmetic value used for representing the quantity and used in making calculations.

Given that Jan doubled her starting number, added 5, subtract 7, divided by 3, then squared the result.

Let her original number be x

Therefore, {(2x +5 - 7)/3}² = 36

{(2x -2)/3}² = 36

(2x -2)/3 = 6

2x - 2 = 18

2x = 20

x = 10

Hence, Jan's starting number was 10.

Using the exponential distribution, it is found that there is a 0.2231 = 22.31% probability after a call is received, it takes more than 3 minutes for the next call to occur.

The exponential probability distribution, with mean m, is described by the following equation:

[tex]f(x) = \mu e^{-\mu x}[/tex]

In which [tex]\mu = \frac{1}{m}[/tex] is the decay parameter.

The probability of finding a value higher than x is:

[tex]P(X > x) = 1 - P(X \leq x) = 1 - (1 - e^{-\mu x}) = e^{-\mu x}[/tex]

In this problem, the mean is of two minutes, hence the decay parameter is given by:

[tex]\mu = \frac{1}{2} = 0.5[/tex]

The probability that it takes more than 3 minutes for the next call to occur is given by:

[tex]P(X > 3) = e^{-0.5 \times 3} = 0.2231[/tex]

0.2231 = 22.31% probability after a call is received, it takes more than 3 minutes for the next call to occur.

There are many ways to prove this identity. But, I will use the simplest one. If you have a right triangle, the length of the horizontal side is x, the length of the vertical side is y, and the hypotenuse is r. So, the relation between x and r can be written in cosine form:

[tex]\cos\theta=\frac{x}{r}[/tex]

The relation between y and r can be written in sine form:

[tex]\sin\theta=\frac{y}{r}[/tex]

Pythagoras told you that for the right triangle [tex]x^{2}+y^{2}=r^{2}[/tex] should be satisfied. Substitute x and y from the cosine and sine form:

[tex](r\cos\theta)^{2}+(r\sin\theta)^{2}=r^{2}[/tex]

[tex]r^{2}\cos^{2}\theta+r^{2}\sin^{2}\theta =r^{2}[/tex]

the square of r will cancel out, and you can get your identity:

[tex]\cos^{2}\theta+\sin^{2}\theta=1[/tex]

According to the histogram, it is found that about 10% of the students took less than 40 minutes to complete the exam.

An histogram is a graph that shows the number of times each element of x was observed.

In this problem, out of a total of 29 students, the histogram states that:

...

10% of 29 is given by:

0.1 x 29 = 2.9.

About 10% of 29 is of 3, hence, since 1 + 2 = 3, about 10% of the students took less than 40 minutes to complete the exam.
