f(6)=-29

Step-by-step explanation:

f(6)=-5(6)+1

f(6)=-30+1

f(6)=-29

The value of f(6) is -29.

Given,

f(x)= -5x+1

We need to find f(6).

A function is denoted by f(x) and the point can be a value of x.

The x values are called domain and f(x) is called the output.

Example:

f(x) = x + 2

At x = 1

f(1) = 1 + 2 = 3.

Find f(x) = -5x + 1 at x = 6.

f(x) = -5x + 1

f(6) = - 5 x 6 + 1

     = -30 + 1

     = -29

This means the function f(x) is -29 at x = 6.

Thus the value of f(6) is -29.

Step-by-step explanation:

because on how you show for 2 when you want to win have an accurate meaning of an number

Answer: Either spinner

Step-by-step explanation: I hope this makes sense, as I had the same question :)

I  would choose either spinner because there is an equally likely probability to land on a greater number using  either one.  If you join the same numbers together on spinner 1 (all the 1's together, 2's together,  and 3's together), the section they would make would be the same size as that same number section on spinner 2.  

OR (more detailed one)-

The probability of landing on a number greater than your friend on either spinner is equally likely. 1 and 2 on the first spinner are both 3/8 of the spinner and 3 is 2/8 which is the same ratios as the second spinner. The difference is that on spinner #1, the numbers are split up and spread out from each other (ex. 1,2,3,2,3,1), and in spinner #2 all the 1's, 2's, and 3's are together to make bigger looking chunks. The area of each number is the same on both spinners.

Answer:

[tex]V=35.3\ m^3[/tex]

Step-by-step explanation:

-Given the cone's height is 9.1m and the Circumference is 12.1

#We use the circumference formula to calculate the radius:

[tex]C=2\pi r\\\\12.1=2\pi r\\\\r=\frac{12.1}{2\pi}=\frac{6.05}{\pi}\ cm[/tex]

-The volume of the cone using the radius above can then be calculated as follows:

[tex]V=\pi r^2\frac{h}{3}\\\\=\pi\times(\frac{6.05}{\pi})^2\times \frac{9.1}{3}\\\\\\=35.3\ m^3[/tex]

Hence, the cone's volume is [tex]35.3\ m^3[/tex]

Answer:

Her annual salary is $45,845.28

Step-by-step explanation:

Multiplication is the process of multiplying. Celia' s annual salary is $48,845.28.

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.

Given that Celia's biweekly salary is $1,763.28. Therefore, her weekly salary will be,

Celia's weekly salary = Celia's biweekly salary/ Number of weeks

Biweekly mean once in two weeks, therefore,

Celia's weekly salary = $1,763.28 / 2 weeks

Celia's weekly salary = $881.64 per week

Now, a complete year has 52 weeks, therefore, Celia's annual salary will be,

Celia's annual salary = Celia's weekly salary × Number of weeks in a year

                                   = $881.64 per week × 52 weeks

                                   = $48,845.28

Hence, Celia' s annual salary is $48,845.28.

Step-by-step explanation:

Data

Right triangle

hypotenuse = 24

Opposite side = 15

Adjacent side = ?

Process

1.- Calculate the adjacent side using the Pythagorean theorem.

          hypotenuse² = opposite side² + adjacent side²

-Solve for adjacent side

          Adjacent side² = hypotenuse² - opposite side²

-Substitution

           Adjacent side² = 24² - 15²

-Simplification

           Adjacent side² = 576 - 225

           Adjacent side = 351

-Result

           Adjacent side = 18.73°

2.- Find the value of x°

a) Using sin x

              sinx = Opposite side/Hypotenuse = 15/24 = 0.625

                  x = 38.68°

b) Using cos x

              cos x = Adjacent side/Hypotenuse = 18.73/24 = 0.78

              cos x = 38.68°

c) Using tan x

              tanx = Opposite side / Hypotenuse = 15/18.73 = 0.80

             tan x = 38.68°

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  Please have a look at the attached file below.

Given:

So assume that the the playground is divided into 5 equal part

=> 1 part is used for students to sit and read or (1/5)

=>  the remaining equal part is 4  or (4/5)

Because 2/3 of the remaining part is used for playing soccer

=> the equation represents the part of the playground used for soccer is:

2/3 of 4/5

= 2/3* 4/5

= 8/15

To find the part of the playground used for soccer, remember one-fifth is for reading, leaving four-fifths. Then, calculate three-quarters of the remaining area for soccer.

To represent the part of the playground used for soccer, we need to consider that one-fifth of the playground is used for students to sit and read. Therefore, the remaining four-fifths of the playground is available for other activities. Since three-quarters of the remaining playground is used for playing soccer, the equation representing the part of the playground used for soccer is:

4/5 * 3/4 = 12/20 = 3/5

Answer:

P(A) ≠ P(D)

Step-by-step explanation:

P(A|D) = P(AD)/P(D)

P(D|A) = P(AD)/P(A)

The two denominators are not equal, so the quotients cannot be equal.

P(A|D) and P(D/A) are not equal because the total number of A and D are not equal.

It is a branch of mathematics that deals with the occurrence of a random event.

From the table, we have the following parameters:

n(A) = 8

n(D) = 10

n(A and D) = 2

P(A|D) and P(D|A) are both conditional probabilities, and they are calculated using:

P(A|D)=2/10

=1/5 = 0.2

P(D/A)= 2/8

=1/4

From the above computations, we have:

P(A|D)≠P(D/A)

Hence, P(A|D) and P(D/A) are not equal because the total number of A and D are not equal.

Answer:

see explanation

Step-by-step explanation:

Given

y = 3(x - 3)(x - 2)

To find the x- intercepts, let y = 0, that is

3(x - 3)(x - 2) = 0

Equate each factor to zero and solve for x

x - 3 = 0 ⇒ x = 3

x - 2 = 0 ⇒ x = 2

Thus the x- intercepts are x = 2 and x = 3

To find the y- intercept let x = 0 and equate for y, that is

y = 3(0 - 3)(0 - 2) = 3(- 3)(- 2) = 3 × 6 = 18

Thus the y- intercept is y = 18

Answer:

21x-15

Step-by-step explanation:

Use the distributive property:

3×7x=21x

3×5=15

Don't forget the - sign!!!

So,

3(7x - 5) = 21x - 15

Final answer:

The expression 3(7x - 5) using the distributive property is equivalent to 21x - 15, which is obtained by multiplying 3 by each term inside the parenthesis.

Explanation:

The expression 3(7x
- 5) is equivalent to 21x - 15. This process is known as the distributive property, where you multiply the number outside the parenthesis by each term inside the parenthesis. Let's break it down step by step:

Multiply the first term inside the parenthesis by 3: 3 ×7x = 21x.

Multiply the second term inside the parenthesis by 3: 3 ×(-5) = -15.

Combine these results to get the equivalent expression: 21x - 15.

Answer:

Explanation:

Call the quadrants I, II, III, and IV, counterclockwise, and the kinds of flowers A, B, C, and D.

Start by assigning a flower of kind A to quadrant I.

Then, quadrant II can have flower B, C, or D.

If quadrant III has A, then quadrant IV can have either B, C, or D. That is 3 different gardens.

If quadrant III has C, then quadrant IV can have either B or D. That is 2 different gardens.

If quadrant III has D, then quadrant IV can either either B or C. That is 2 different gardens.

Those are all the possible different gardens if A is assigned to quadrant I and B is assigned to quadrant II: 3 + 2 + 2 = 7.

Working yet with A in quadrant I but assigning C to quadrant II, you can make the same reasoning as above to get other 7 gardens.

The same with A in quadrant I but D in quadrant II, other 7 different gardents.

In total, you find 7 × 3 = 21 different gardens when flowers of kind A are assingned to quadrant I.

Starting with a flower of kind B in quadrant I, there will be other 21 different gardens. The same for C and D. Then, in total, there are 4 × 21 = 84 different possible gardens.

Answer:

84

Step-by-step explanation:

Quadrants A and C either have the same kind of flower, or they have different flowers.

If quadrants A and C have the same kind of flower, there are 4 ways to choose this flower. There are then 3 ways to choose the flower for quadrant B, and 3 ways to choose the flower for quadrant D, so there are 4 x 3 x 3 = 36 possible ways in this case.

If quadrants A and C have different kinds of flowers, then there are 4 ways to choose the flower for quadrant A, then 3 ways to choose the flower for quadrant C. Then there are 2 ways to choose the flower for quadrant B, and 2 ways to choose the flower for quadrant D, so there are 4 x 3 x 2 x 2 = 48 possible ways in this case.

Therefore, there are a total of 36 + 48 = 84 ways to plant the flowers.
