Find the first term of the arithmetic sequence in which t22=1008 and d= -8

Answers

tn = nth term
t22 = 22nd term
d = common difference
d = -8
n = number of terms
n = 22
.
tn = t1 + (n - 1)d
t22 = t1 + (n - 1)d
1008 = t1 + (22 - 1)-8
1008 = t1 + (21)-8
1008 = t1 + 168

Which of the following represents “the sum of the abscissa and the ordinate is negative four”?

A. x + y = -4

B. xy = 4

C. 4x + 4y = 0

Answers

Answer: A

When you are working with coordinate points, the x-value in the point is called the abscissa. The y-value in the point is called the ordinate.

Therefore all you have to do is add the x and y of the coordinates to get our equation. Don't forget that the sum has to be -4 according to the problem.

Answers

Volume: 39,304 cubic yards

To find the volume, you simply have to use the formula that is given. It is V = s^3. This means you multiply the side by itself 3 times.

What is an angle?

When two lines or rays converge at the same point, the measurement between them is called a "Angle."

The question in incomplete.

The complete question is:

A plane is traveling due south. The wind is blowing 30° east of south at 50 miles/hour. If the plane's resultant speed due to the wind is 180 miles/hour, what is the plane's actual speed, rounded to the nearest integer?

120 miles/hour130 miles/hour135 miles/hour140 miles/hour

From the data given in the question:

Using Cosine Law:

c² = a² + b² - 2 ac cos C

180² = 50² + x² - (2×50)x cos 150°

32400 - 2500 - x² = 86.6x

29,900 - x² = 86.6 x

x² + 86.6x - 29900 = 0

After solving the above quadratic equation:

x = 135 miles/hour

Thus, the plane's actual speed is 135 miles/hour if the plane is traveling due south. The wind is blowing 30° east of south at 50 miles/hour option (C) 135 miles/hour is correct.

Answers

Answer:
y = -5x + 6

Explanation:
The equation of line in slope-intercept form is:
y = mx + c
where:
m is the slope
c is the y-intercept

We are given that the slope = -5. Therefore, the equation becomes:
y = -5x + c

Now, we need to get the value of c. To do so, we will substitute with the given point (3,-9) in the equation and solve for c as follows:
y = -5x + c
-9 = -5(3) + c
-9 = -15 + c
c = -9 + 15 = 6

Based on the above, equation of line is:
y = -5x + 6

When translating a figure using a combination of two translations, is the resulting figure congruent to the original figure?

Answers

it has to be the original figure but it is in a different spot on the graph

Final answer:

When translating a figure using two translations, the end result is a figure that is congruent to the original. This is due to the fact that translations move the shape without altering its size or orientation.

Explanation:

Yes, when translating a figure using a combination of two translations, the resulting figure is congruent to the original figure. When a figure is translated, it is moved without being turned or flipped, the size and shape remains the same, hence making it congruent. For example, consider a parallelogram. If two different vectors A and B are chosen to translate it, following the rules of vector summation, the figure moved, known as the resultant vector retains the dimensions and angles of the original parallelogram, albeit in a different location.

The sides of a right triangle have a relationship as depicted below, where x is the length of the longer leg in inches.

The area of this triangle, A, is equal to the perimeter of this triangle.

Create a system of equations to model this situation. Determine if there are any solutions, and, if possible, whether or not they are viable.

How many total possible solutions are there to this system?

Of any possible solutions, how many are viable solutions for this situation?

Answers

The equation to represent the area of the triangle would be:
y = 1/2(x²) - (7/2)x

The equation to represent the perimeter of the triangle would be:
y = 3x - 6

The solutions to the system would be (12, 30) or (1, -3). The only viable solution is (12, 30).

Explanation
The area of a triangle is found using the formula
A = 1/2bh

For our triangle, b = x and h = x-7, so we have:
A = 1/2(x)(x-7)
A = 1/2(x²-7x)
A = 1/2(x²) - (7/2)x

We will replace A with y, so we have:
y = 1/2(x²) - (7/2)x

The perimeter of a triangle is found by adding together all sides, so we have:
P = (x-7) + x + (x+1)

Combining like terms we get:
P = 3x - 6

We will replace P with y, so we have:
y = 3x - 6

Since both equations have y isolated on one side, it will be easy to use substitution to solve the system:

3x - 6 = 1/2(x²) - (7/2)x

It's easier to work with whole numbers, so we will multiply everything by 2:
6x - 12 = x² - 7x

We want all of the variables on one side, so we will subtract 6x:
6x - 12 - 6x = x² - 7x - 6x
-12 = x² - 13x

When solving quadratics, we want the equation equal to 0, so we will add 12:
-12+12 = x² - 13x + 12
0 = x² - 13x + 12

This is easy to factor, as there are factors of 12 that sum to -13; -12(-1) = 12 and -12+-1 = -13:
0 = (x-12)(x-1)

Using the zero product property, we know that either x-12=0 or x-1=0; therefore x=12 or x=1.

Putting these back into our equation for perimeter (the simplest one) we have:
y = 3(12)-6 = 36-6 = 30; (12, 30);
y = 3(1) - 6 = 3 - 6 = -3; (1, -3)

We cannot have a negative perimeter, so the only viable solution is (12, 30).

Answer:

two possible and one viable

Hi there!

To make this a bit simpler, first, we should convert a year into months:

1 yr = 12 mo

Now, we multiply 12 by 3/4, since we're trying to find 3/4 of a year.

Tennis balls are sold in tubes that hold 3 tennis balls each. A store stacks 2 rows of tennis ball tubes on its shelf. Each row has 7 tubes in it. How many tennis balls are there in all?

Answers

There are 42 tennis balls in all

There are a total of 42 tennis balls on the shelf.

To determine the total number of tennis balls on the shelf, we first need to find out how many tennis ball tubes are there. Each row has 7 tubes and there are 2 rows:

Number of tubes per row = 7

Number of rows = 2

Total number of tubes = 7 tubes/row × 2 rows = 14 tubes

Since each tube contains 3 tennis balls, we multiply the total number of tubes by the number of tennis balls per tube:

Number of tennis balls per tube = 3

Total number of tennis balls = 14 tubes × 3 tennis balls/tube = 42 tennis balls

Therefore, the store has a total of 42 tennis balls on the shelf.

2x = 11 + 27
38 = 2x
38/2 = x
19 = x

-Love, live, and watch anime.

11 less implies: -11

two times a number (x) implies: 2x

equal to 27 implies: = 27

Set the equation together.

2x - 11 = 27 is your equation.

Solve for x. Note the equal sign. What you do to one side you do to the other. Add 11 to both sides

2x - 11 (+11) = 27 (+11)

2x = 38

Isolate the x. Divide 2 from both sides.

2x/2 = 38/2

x = 19
