To find the 20th term in this sequence, we can simply keep on adding the common difference all the way until we get up to the 20th term.
The common difference is the number that we are adding or subtracting to reach the next term in the sequence.
Notice that the difference between 15 and 12 is 3.
In other words, 12 + 3 = 15.
That 3 that we are adding is our common difference.
So we know that our first term is 12.
Now we can continue the sequence.
12 ⇒ 1st term
15 ⇒ 2nd term
18 ⇒ 3rd term
21 ⇒ 4th term
24 ⇒ 5th term
27 ⇒ 6th term
30 ⇒ 7th term
33 ⇒ 8th term
36 ⇒ 9th term
39 ⇒ 10th term
42 ⇒ 11th term
45 ⇒ 12th term
48 ⇒ 13th term
51 ⇒ 14th term
54 ⇒ 15th term
57 ⇒ 16th term
60 ⇒ 17th term
63 ⇒ 18th term
66 ⇒ 19th term
69 ⇒ 20th term
This means that the 20th term of this arithemtic sequence is 69.

Step-by-step explanation:
A pool table is 8 feet long and 4 feet wide. How far is it from one corner pocket to the diagonally opposite corner pocket?
Using the Pythagorean theorem, the diagonal distance from one corner pocket to the diagonally opposite corner pocket on an 8 foot by 4 foot pool table is about 8.94 feet.
To determine the distance from one corner pocket to the diagonally opposite corner pocket on a pool table, we can use the Pythagorean theorem because the pool table forms a rectangle and the diagonal forms a right triangle with the length and width of the table. Given the dimensions of the pool table as 8 feet long and 4 feet wide, we can label these as the two sides of the right triangle.
The Pythagorean theorem states that for a right triangle with sides of lengths a, b, and hypotenuse c, the relationship between these sides is [tex]a^2 + b^2 = c^2[/tex]. Substituting the given values, we have:
Let's denote the length (8 feet) as a and the width (4 feet) as b.Using the theorem, we calculate the hypotenuse c as [tex]\sqrt{(8^2 + 4^2)}.[/tex]Compute the square of each side: [tex]8^2[/tex] = 64 and [tex]4^2[/tex] = 16.Add these together: 64 + 16 = 80.The hypotenuse (diagonal) c is the square root of 80, which simplifies to 4 [tex]\sqrt(5)[/tex] feet or approximately 8.94 feet.Therefore, the diagonal distance from one corner pocket to the diagonally opposite corner pocket is about 8.94 feet.

Determine the compound interest earned on $200 invested at 3.25% compound annually for 6 years
Answer:
$882.24 compound interest earned / $1,082.24 total
Step-by-step explanation:
You are going to want to use the compound interest formula, which is shown below.
[tex]P(1+\frac{r}{n} )^{nt}[/tex]
P = initial balance
r = interest rate
n = number of times compounded annually
t = time
Now lets plug in the values into the equation.
[tex]200(1+\frac{.325}{1} )^{6}[/tex] = 1,082.24
Since we want to know the compound interest earned, just subtract 200 from 1,082.24.
1,082.24 - 200 = $882.24

What are transformations?A function, f, that maps to itself are known as a transformation, or f: X- X. The pre-image X becomes the picture X following the transformation. This transformation can use any operation, or a combination of operations, including translation, rotation, reflection, and dilation. Translation, rotation, reflection, and dilation can all be used to move a function in one direction or another.
Given that the initial coordinate of triangles ABC are at points

How many different ways can 9 trumpet players in the marching band line up?
Answer:
362880 ways
Step-by-step explanation:
In this case, the order does matter therefore to know how many ways it can be aligned, we must resort to permutations.
The formula for permutations is:
P = n!
we know that there are 9 trumpet players, therefore:
P = 9!
P = 362880
So there are 362,880 ways to line up

Answer:
24
Step-by-step explanation:
cos(x) is just a trigonometric function. To find it on a right triangle, you take the "adjacent" side, which should be the side next to the angle x, and divide it by the hypotenuse.
In this case, the adjacent side is 12. We don't know the hypotenuse, but we can figure it out using the Pythagorean Theorem: [tex]\sqrt{9^{2}+12^{2}}[/tex] = [tex]\sqrt{225}[/tex] = 15. So, the hypotenuse is 15.
Thus, cos(x) = 12/15 = 4/5. We want 30 * cos(x), so we get: 30 * (4/5) = 24, and that is our answer.
Answer:
24
Step-by-step explanation:
From the mnemonic SOHCAHTOA you would know that cos x = adjacent/hypotenuse.
Adjacent side is given as 12, but we must calculate the hypotenuse.
For that we use Pythagoras.
hypotenuse = √(9²+12²) = 15
Now you can calculate
30×cos(x) = 30×12/15 = 24

Step-by-step explanation:
For the firs one draw a dot where they start. Then draw a line going down and label it 10. Next draw a line going left and label it 24. Connect the end of those who lines to form a triangle. Now we can use the pythagorean theory.
a^2 + b^2 = c^2
a^2= side one (you choose)
b^2= side two (whichever side you didn't use out of the two)
c^2= the hypotenuse( this is the diagonal line you drew connecting the two lines at the end)
10^2 + 24^2 =c^2
100 + 576 =c^2
676=c^2 Since the C is still squared we have to squareroot both sides. This will cancel oout the ^2 on the C.

Annita is sewing a lace edge around a rectangular quilt. She will need 150 inches of lace to do the entire quilt. If the quiltis 42
inches wide, how long is the quilt?
A. 75 inches
B. 66 inches
C. 31 inches
D. 33 inches
With a total perimeter of 150 inches and a width of 42 inches, the length was calculated to be 33 inches, option D.
To determine how long the quilt is, we need to calculate the perimeter of the rectangular quilt and then solve for the missing length. Since Annita needs 150 inches of lace, we know this is the total perimeter (P) of the quilt. The quilt is 42 inches wide. The formula for the perimeter of a rectangle is P = 2(length) + 2(width). We can set up the equation as 150 = 2(length) + 2(42).
Now let's solve for the length (L):
150 = 2L + 84 (since 2(42) is 84)150 - 84 = 2L66 = 2LL = 33 inchesThe length of the quilt is 33 inches, which corresponds to option D.
The length of the quilt is 33 inches.
The correct option is (D).
To find the length of the quilt, we need to use the formula for the perimeter of a rectangle, which is given by:
[tex]\[ \text{Perimeter} = 2 \times (\text{Length} + \text{Width}) \][/tex]
Given that the width of the quilt is 42 inches and Annita needs 150 inches of lace to go around the entire quilt, we can set up the equation as:
[tex]\[ 150 = 2 \times (\text{Length} + 42) \][/tex]
Now, let's solve for the length [tex](\( \text{Length} \)):[/tex]
[tex]\[ 150 = 2 \times (\text{Length} + 42) \][/tex]
[tex]\[ 75 = \text{Length} + 42 \][/tex]
Subtract 42 from both sides:
[tex]\[ 75 - 42 = \text{Length} \][/tex]
[tex]\[ \text{Length} = 33 \][/tex]
So, the length of the quilt is 33 inches. Therefore, the answer is option D. 33 inches.

What is Parabola?A parabola is a U-shaped curve this is drawn for a quadratic function,
f(x) = ax² + b x + c. The graph of the parabola is downward (or opens down), when the price of a is much less than 0, a < 0. The graph of the parabola is upward (or opens up) when the value of a is more than 0, a > 0.
Given function, y = 3x²+7x+2
Compare the given function to f(x) = ax² + b x + c ,
The graph of given function is upward (or opens up) because the value of 3 is more than 0, 3 > 0.
The x-intercept of given function are (-1/3, 0) and (-2,0)
The y-intercept of given function is (0,2)
Here is a graph represents function of y = 3x²+7x+2

brainly.com/question/4074088
#SPJ5
The correct option is A. Graph A. It shows an upward-opening parabola with a vertex and y-intercept that match the derived values.
1. Direction of the Parabola : Since the coefficient of [tex]\( x^2 \)[/tex] (which is [tex]3[/tex]) is positive, the parabola opens upwards.
2. Vertex : The vertex of a parabola in the form [tex]\( y = ax^2 + bx + c \)[/tex] can be found using the formula for the x-coordinate of the vertex, [tex]\( x = -\frac{b}{2a} \)[/tex]
For the given function:
[tex]\[ a = 3, \quad b = 7 \][/tex]
So,
[tex]\[ x = -\frac{7}{2 \times 3} = -\frac{7}{6} \][/tex]
Next, we find the y-coordinate of the vertex by plugging [tex]\( x = -\frac{7}{6} \)[/tex] back into the equation:
[tex]\[ y = 3\left(-\frac{7}{6}\right)^2 + 7\left(-\frac{7}{6}\right) + 2 \][/tex]
Let's compute that:
[tex]\[ y = 3 \times \frac{49}{36} - \frac{49}{6} + 2 \][/tex]
[tex]\[ y = \frac{147}{36} - \frac{294}{36} + \frac{72}{36} \][/tex]
[tex]\[ y = \frac{147 - 294 + 72}{36} \][/tex]
[tex]\[ y = \frac{-75}{36} \][/tex]
[tex]\[ y = -\frac{25}{12} = -2.083 \][/tex]
Thus, the vertex is approximately at [tex]\(\left( -\frac{7}{6}, -\frac{25}{12} \right)\)[/tex]
3. Y-Intercept : This is the value of [tex]\( y \)[/tex] when [tex]\( x = 0 \)[/tex]
[tex]\[ y = 3(0)^2 + 7(0) + 2 = 2 \][/tex]
The graph should cross the y-axis at [tex]\( y = 2 \)[/tex]
Now, let's compare these features with the provided graphs:
The parabola should open upwards.
The y-intercept should be [tex]2[/tex].
The vertex should be approximately at [tex]\( \left( -\frac{7}{6}, -\frac{25}{12} \right) \)[/tex]
