Answer:

The 2nd, 3rd and last ones work.

Step-by-step explanation:

-27÷9 is -3. Positive no. ÷ Negative no. = Negative number

So you now need to find which of the answers have -3 as the answer.

The first one won't work since it's answer will be positive.

18/-6= -3 so this works.

The next one won't work since it's quotient will be a positive number.

27/-9 = -3 this also works.

The next one won't work since it's quotient will also be a posititve number.

-9/3 = -3 this also works.

Hope this helps:)

Find the first four terms of the recursive sequence defined by the following formula: an = an-1 4 where a4 = 2 1 4 , , , 2 1 4.

Elina [12.6K]

The first four-term of the sequence is found by the given equation $a_{n-1} = 4a_n$ is given as 144, 36, 9, and 9/4.

<h3>What is a sequence?</h3>

A sequence is a list of elements that have been ordered in a sequential manner, such that members come either before or after.

The given equation will be

$\rm a_n = \dfrac{a_{n-1}}{4} \\\\a_{n-1} = 4a_n$

And

$a_4 = 2 \dfrac{1}{4} = \dfrac{9}{4}$

For n = 4, we have

$\rm a_{4-1} = 4a_4\\\\a_3 \ \ \ = 4*\dfrac{9}{4} \\\\ a_3 \ \ \ = 9$

For n = 3, we have

$\rm a_{3-1} = 4a_3\\\\a_2 \ \ \ = 4*9 \\\\ a_2 \ \ \ = 36$

For n = 2, we have

$\rm a_{2-1} = 4a_2\\\\a_1 \ \ \ = 4*36 \\\\ a_1 \ \ \ = 144$

Why do you sometimes have only one multiplication sentence for an array

taurus [48]

Arrays are useful models for multiplication which can be used in a variety of ways, ranging from highly structured lessons to games and open investigations. An array is formed by arranging a set of objects into rows and columns. Each column must contain the same number of objects as the other columns, and each row must have the same number as the other rows.

The following array, consisting of four columns and three rows, could be used to represent the number sentence 3 x 4 = 12.

Given circle E with diameter CD and

irina1246 [14]

The Pythagoras is the sum of the square of two sides equal to the square of the longest side. Then the value of AC is 24 units.

<h3>What is a circle?</h3>

It is a locus of a point drawn an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.

Given circle E with diameter CD and radius EA. AB is tangent to E at A.

If AD = 10 and CD = 26.

Then the value of AC will be

We know that the tangent and radius make 90 degrees. Then the triangle is a right-angle triangle.

Then the AC is given by the Pythagoras theorem.

B² = H² - P²

B² = 26² - 10²

B² = 576

B = 24
