Find the 10th term of the geometric sequence 1,3,9, ...

Answer:

17

Step-by-step explanation:

a^2 + b^2 = c^2

a^2 = 8^2 = 64

b^2 = 15^2 = 225

64 + 225 = 289

c^2 = 289

c = Square root of 278

c = 17

Answer:

y < -2

Step-by-step explanation:

7 - 6y > 19

Subtract 7 from each side

7-7 - 6y > 19-7

-6y > 12

Divide each side by -6. remembering to flip the inequality

-6y/-6 < 12/-6

y < -2

The value of the 20th term in this sequence will be 102

Since we are given f(n)=6n−18.

In this case, we have been given n to be 20. Therefore, f(n)=6n−18 will then be written as:

f(n)=6n−18

f(20) = 6(20) - 18

f(20) = 120 - 18

f(20) = 102

In conclusion, value of the 20th term in this sequence will be 102

To solve for x for the second answer, multiply 2 by y

[tex]y = \frac{x}{4} \\\\y (4) = x\\\\x = 2(4)\\ x= 8[/tex]

To solve for x for the third answer, multiply 9 by y

[tex]y = \frac{x}{4} \\\\y (4) = x\\\\x = 9(4)\\ x= 36[/tex]

Answer:

A) Irrational, because it is not a terminating or repeating decimal.

Step-by-step explanation:

Every time a square root results in a decimal, it will always never end, and never repeat. The square root of 35 qualifies for both of these qualities, therefore, making the answer (A). Hope this helps!

Answer:

Removing the number 7 wont change the median nor the range

Part A

Like with any other rectangle, we multiply the length and width to get the area

This applies even when we have algebraic expressions like this (recall that x is simply a placeholder for a number).

So,

area = length*width

area = (4x+5)*(3x+10)

area = w(3x+10) ..... replace (4x+5) with the variable w

area = 3xw + 10w ..... distribute

area = 3x(4x+5)+10(4x+5) .... plug in w = 4x+5

area = 3x*4x+3x*5 + 10*4x+10*5 .... distribute again

area = 12x^2+15x + 40x+50

area = 12x^2+55x+50

Answer: 12x^2+55x+50

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

Part B

The degree of any single variable polynomial is the largest exponent. In this case, the largest exponent is 2. This 2nd degree polynomial is considered a quadratic. Because we have three terms, this quadratic polynomial is also a trinomial. So there are many ways to describe the result of part A. Possibly the quickest way to describe it is to say "quadratic trinomial" to say all that has been mentioned in this paragraph.

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

Part C

The concept of closure is the idea of taking two objects of the same type, applying some operation to them, and getting an output object of the same type.

Admittedly that last paragraph is a bit vague so I'll go over a few examples.

A non-example would be dividing whole numbers. Something like 10/2 = 5 is a whole number but 10/3 = 3.33 is not. This shows that integers are not closed under division. We don't always get a whole number output.

With polynomials, multiplying any two of them will result in some other polynomial. It's basically using the two examples in the bullet points and building upon them. That's the short version of why polynomials are closed under multiplication.

For this particular problem, (4x+5), (3x+10), and 12x^2+55x+50 are all polynomials.

In terms of notation,

polynomialA * polynomialB = polynomialC

This notation hopefully shows that multiplying any two polynomials leads to another polynomial.

Answer:

a taco is 1.25 and a drink is 0.95

Step-by-step explanation:

tacos = t

drinks = d

5t + 3d = 9.10

3t + d = 4.70

this is a simultaneous equation so times the first one by one and the second by 3 and then take them away from each other and solving to get

t = 1.25 and d=0.95

one drink is $0.95

one taco is $1.25

Answer:

Angle ASB I's 67.5 and Angle back is 22.5

Step-by-step explanation:

well you need to add the right expressions for the shorter lines so that there is no overlap. otherwise GK would be too long.

so, how can we combine the 3 red lines to get exactly GK ?

we cannot just add 2 of these lines. the results would always be either too long or too short.

but we see "2x + 3" overlaps a bit with "4x - 3". and hey, the third line "x" is just the length of the overlap of the other 2 lines.

so, we can add the first 2 lines, IF we reduce first one of them by the overlap length.

I picked the second line.

so, we have

2x + 3 - x + 4x - 3 = GK

5x = GK

so, "5x" is the algebraic expression representing GK.

now, if GK = 30, then we know

5x = 30

x = 6

GH = 2x + 3 - x (again, we need to shorten that line by the overlap length to count only to H)

= 2×6 + 3 - 6 = 6 + 3 = 9

JK = GK - GJ = 30 - (2x + 3) (here we need the full line, as we are dealing with J)

= 30 - 2×6 - 3 = 15

Hello Again!

The midpoint divides a length into two equal distances.

Equation: 4x+2 = 4x+2

or 2(4x + 2) = 5x + 13

x =

2(4x + 2) = 5x + 13

8x + 4 = 5x + 13

-5x        -5x

3x + 4 = 13

-4          -4

3x = 9

divide 3 on both sides:

x = 3

PQ = 28

Answer:

3 < x < 8

Step-by-step explanation:

Solve each part separately

2x - 1 > 5 ( add 1 to both sides )

2x > 6 ( divide both sides by 2 )

x > 3 , that is

3 < x

and

3x - 5 < 19 ( add 5 to both sides )

3x < 24 ( divide both sides by 3 )

x < 8

Then putting the two together

3 < x < 8

The image of (-9,-5) after a reflection over the line y = -x is (5, 9) after applying the geometric transformation.

It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

It is given that:

The coordinate of the point: (-9, -5)

The reflection line: = y = -x

The transformation rule:

(x, y) → (-y, -x)

The image of (-9,-5) after a reflection over the line y = -x is (5,9).

Thus, the image of (-9,-5) after a reflection over the line y = -x is (5, 9) after applying the geometric transformation.
