Answer 1

Answer:

Answer:

1, 3, 9, 27

Step-by-step explanation:

$a_n = 3^(n - 1)$

You need the first 4 terms, so let n = 1, and evaluate the expression. Then do the same for n = 2, n = 3, and finally n = 4.

n = 1

$a_1 = 3^(1 - 1) = 3^0 = 1$

n = 2

$a_2 = 3^(2 - 1) = 3^1 = 3$

n = 3

$a_3 = 3^(3 - 1) = 3^2 = 9$

n = 4

$a_4 = 3^(4 - 1) = 3^3 = 27$

Which of the following is not a congruence transformation? A.Translating
B.Rotating
C.Dilating

Answers

The answer is C.) Dilating
because dilating doesn't make them congruent anymore, but they change size to be either smaller or bigger than one another, but the shape itself does not change.

Instructions:Select the correct answer from each drop-down menu. ABCDEFGH is a regular octagon. The minimum degree of rotation by which this octagon can map onto itself is °. It will take increments of that degree of clockwise rotation for A′ (the image of A) to coincide with C. NextReset

Answers

Answer:

Remember that regular octagon is a figure with eight sides, where all of them are equal. The image attached shows a regular octagon.

So, if we want to map the octagon on to itself using rotation, we need to rotate 90° clockwise, or make to moves of 45° each, that way the octagon would be as the original one because it has equal sides.

When you rotate the first 45°, you would have like an inclined octagon, so you need to rotate another 45° to get the same octagon as the original.

So, the minimum degree would be 45°, doing it twice.

It would be 45 degrees. Since a an octagon takes 8 turns to go around and there is a total of 360 degrees, you can divide 360 by 8 to get your answer of 45 degrees. For answering questions like this you need to take 360 and divide it be the amount of sides to get the minimum amount of degrees of rotation.

C(squared)L(squared) + 100v(squared) = 100c(squared)
I have to solve for L

Answers

first subtract 100v² from both sides to get:

C²L²=100c²-100v²

Then divide both sides by C²:

L²=(100c²-100v²)/C²

Then take the square root of both sides:

L=+ or - the square root of (100c²-100v²)/C²

Answer:

L = ±√( (100c² - 100v²) / C² )

Step-by-step explanation:

You're just doing reverse PEMDAS.

So first get all the values correlated with L on one side and the non-L values on the other side using subtraction/addition.

Then remove all coefficient using multiplication/division.

Then take the sqareroot to get rid of the squre on the v.

Remember that taking squareroot gives a ± answer because

Enter the value of 18 + t2 - 5x3 when t = 4

Answers

Answer:

Step-by-step explanation:

If t=4

18+t2 would equal “26”

Then 26x3 would be “78”

Final answer:

When t = 4, the part of the equation 18 + t^2 evaluates to 34. We cannot compute - 5x^3 without the value of x.

Explanation:

The subject of the question is Mathematics, more specifically, the topic of algebraic expressions. Given an equation, 18 + t^2 - 5x^3, you'd like to find the value when t = 4. However, the value of x is not provided which is required to fully solve this expression. If we ignore the variable x, and only substitute the value of t in the expression, it will be:

18 + 4^2 = 18 + 16 = 34.

So, when t = 4, the part of the equation 18 + t^2 evaluates to 34. However, we cannot calculate - 5x^3 without having the value of x.
