Step-by-step explanation:

=======================================================

Explanation:

As you can probably guess, the first equation [tex]a_1 = 3[/tex] says that the first term is 3. The small '1' indicates "first term". So writing [tex]a_2[/tex] represents the second term, then [tex]a_3[/tex] is notation for the third term, and so on.

The second term is found by plugging in n = 2 into the second equation and computing to get...

[tex]a_n = 4*a_{n-1} + 2\\\\a_2 = 4*a_{2-1} + 2\\\\a_2 = 4*a_{1} + 2\\\\a_2 = 4*3 + 2\\\\a_2 = 12 + 2\\\\a_2 = 14\\\\[/tex]

The second term is 14. The steps above basically say: "to get the second term, we multiply the first term by 4, then add on 2"

In other words,

second term = 4*(first term) + 2

second term = 4*(3) + 2

second term = 12 + 2

second term = 14

-----

This can be extended to get the third term

third term = 4*(second term) + 2

third term = 4*(14) + 2

third term = 56 + 2

third term = 58

and finally,

fourth term = 4*(third term) + 2

fourth term = 4*(58) + 2

fourth term = 232 + 2

fourth term = 234

Answer:

250[tex]\leq[/tex]5s+8ns

Step-by-step explanation:

the total fees are $250, meaning they would still be able to make the fees if they'd oversell the tickets.

each tickets is $5 for students; hence the s

each tickets is $8 for nonstudents; hence the ns

you may replace the variable with anything you'd like or what fits the direction.

The inequality describes the number of student and non student tickets that to be sold for the drama class to be able to pay the fees will be 5x+8y≥250

A relationship between two expressions or values that are not equal to each other is called inequality.

Given that, The total fees for the high school play are $250. Tickets to the play cost $5 for students and $8 for non students.

Let the cost of students be x and that of non student's be y.

According to question,

5x+8y≥ 250

Hence, The inequality describes the number of student and non student tickets that to be sold for the drama class to be able to pay the fees will be 5x+8y≥250

The most preferred pets by students are Dogs. Therefore, the correct answers are B and C option.

A. It is given that, the number of Dogs are 28.

B. It is given that, the number of other Pets are

7+15+10 = 32

Thus, the number of other pets are greater than dogs.

C. The total number of pets are 60.

Here, the number of hamsters are

1/4 ×60 = 15

D. The number of hamsters and fish

= 15+10 = 25

The number of dogs are more than the number of fish and hamsters

Therefore, the correct answers are B and C option.

Answer:

4/11 is already simplified as much as it can be in fraction form. as a percent its 36.3636%

Step-by-step explanation:

The simplified expression of 4/11 is 4/11

From the question, we have the following parameters that can be used in our computation:

4/11

This means that we divide 4 by 11

So, we have the following representation

4/11

In the above, we have

The numerator 4 is less than the denominator 11

This means that the expression is already simplified

Hence, the simplified expression is 4/11

Answer:

A.

Step-by-step explanation:

x-1 moves the graph to the right 1 and + 8 moves it up 8

this puts the vertex at (1,8) and the negative infront  of the x makes the graph point down like it is.

The function represented by the graph is : f(x)=-|x-1|+8

The correct option is (A).

A graph is a mathematical diagram which shows the relationship between two or more sets of numbers or measurements.

If we look at the graph, only the portion x-1 makes to move the graph to the right 1 and moves it up 8 which makes the coordinate (1,8).

Also, the negative at the front of x makes graph to move downwards.

Hence, the graph represented the function : f(x)=-|x-1|+8

Answer: 7ft

Step-by-step explanation:

Rectangular Prism = L x W x H

135H = 945

H = 7 ft

Answer:

5ft

Step-by-step explanation:

According to the scenario, computation of the given data are as follows,

Volume = 25π ft cubed

Depth = 3 ft

So, we can calculate the radius by using following formula,

V = 1/3 ×π ×radius squared×depth

25π = 1/3×π×radius squared ×3

Radius squared = 25

Radius = √25

Radius = 5 ft

Hence the radius of the hole is 5 ft.

Answer:

3a

Step-by-step explanation:

What we have as the point O refers to the centroid of the triangle

The centroid splits the distance between the opposite vertex and the middle of the side length that faces it into two; with the longer side being twice the length of the shorter

So what we have here is that;

B1O is half the length of BO

So, if B1O is a cm, BO would be 2a

So we have the entire side length measure as;

a + 2a = 3a

Answer:

This shaded region is consisted of 2 shapes: a right triangle and a semi-circle. To find the overall area, we must first find the are of the 2 shapes and add them together.

Step-by-step explanation:

1. Find the area of the right triangle:

a = 14, b = 2r = 8cm

A1 = ab/2 = 112/2 = 56cm²

2. Find the area of the circle:

r = 4 cm

A2 = πr² = 3.14 × 4² = 50.24cm²

3. Divide the area of the circle to get the area of the semi-circle:

A3 = A2/2 = 50.24/2 = 25.12cm²

4. Add the areas of the right triangle and the semi-circle together:

A1 + A3 = 56 + 25.12 = 81.12cm²

Question:  The probability that s student owns a car is 0.65, and the probability that a student owns a computer is 0.82.

a. If the probability that a student owns both is 0.55, what is the probability that a randomly selected student owns a car or computer?

b. What is the probability that a randomly selected student does not own a car or computer?

Answer:

(a) 0.92

(b) 0.08

Step-by-step explanation:

(a)

Applying

Pr(A or B) = Pr(A) + Pr(B) – Pr(A and B)................. Equation 1

Where A represent Car, B represent Computer.

From the question,

Pr(A) = 0.65, Pr(B) = 0.82, Pr(A and B) = 0.55

Substitute these values into equation 1

Pr(A or B) = 0.65+0.82-0.55

Pr(A or B) = 1.47-0.55

Pr(A or B) = 0.92.

Hence the probability that a student selected randomly owns a house or a car is 0.92

(b)

Applying

Pr(A or B) = 1 – Pr(not-A and not-B)

Pr(not-A and not-B) = 1-Pr(A or B) ..................... Equation 2

Given: Pr(A or B)  = 0.92

Substitute these value into equation 2

Pr(not-A and not-B) = 1-0.92

Pr(not-A and not-B) = 0.08

Hence the probability that a student selected randomly does not own a car or a computer is 0.08

Answer:

Step-by-step explanation:

First equation:  −3x − 5 = 16

 Combine the constants:

 -3x = 21

  Solve for x using division:  x = 21/(-3)   or  x = -7

Second equation:  −4(y − 2) = 12

 Reduce this by dividing both sides by -4:  y - 2 = -3

 Add 2 to both sides, to isolate y:  y = -1

Answer:

The domain is how far left and right it goes on a graph, and the range is how far up and down it goes on a graph. Because this equation is linear (if you graphed it, it would be in a straight line), both the domain and range are infinity, because it keeps going up and to the right, the larger X gets, and smaller and to the left, the more negative X gets.

graph is linear:

y=2x-4

solve for x=o

y=2x0-4       Eliminate 0

y=-4             solved for y

solve for y=0

0=2x-4          add 4

+4      +4

4=2x             divide by 2

/2    /2

4/2 =x

2=x               solved for x

calculate the slope

Solve for x=1

y=2x1-4

y=2-4

y=2             solved for y

Calculating the slope

      y                -y

a= x=1      x=0     =2

            1

The graph is

(0, -4)  (2, 0)
