How can you find the length of ⎯⎯⎯⎯⎯⎯⎯⎯⎯

X varies directly as y, and x = 153 when y = 9. Find x when y = 13.

goblinko [34]

X = 153 = 17* 9, so when <span>y = 13, x= 21*13= 273

x= 17 18 19 20 21
y= 9 10 11 12 13</span>

Whoever gets this correct gets brain, 5 stars and a thanks! An explanation of it would be amazing! Tysm!

MAXImum [283]

Answer:

Greatest to Least:

76

8

-53

-274

76 is the highest positive number, which is then followed by 8

The bigger the NEGATIVE number, the least it is. So, -274 is smaller than -53

The movie theater add 352 people in it.if the people split into eight even groups to watch different movies how many people Will

Dovator [93]

The answer is 44 because the equation is 352 divided 8. And 8 goes into 352 44 times. If you want to check the work you can also multiply 44 and 8, and it should be 352.

So the answer is 44
Hope this Helps:)

Help find the derivative.

Masteriza [31]

Answer:

Step-by-step explanation:

$1.\\f(x)=e^x\\f'(x)=e^x\\2.\\y=x^8-12x^5-3x^2+7x+22\\\frac{dy}{dx}=8x^7-12*5 x^4-3*2x+7+0\\\frac{dy}{dx}=8x^7-60 x^4-6x+7\\3.\\f(x)=e^3\\f'(x)=0$

2. Check the boxes for the following sets that are closed under the given

son4ous [18]

The properties of the mathematical sequence allow us to find that the recurrence term is 1 and the operation for each sequence is

a) Subtraction

b) Addition

c) AdditionSum

d) in this case we have two possibilities

* If we move to the right the addition

* If we move to the left the subtraction

The sequence is a set of elements arranged one after another related by some mathematical relationship. The elements of the sequence are called terms.

The sequences shown can be defined by recurrence relations.

Let's analyze each sequence shown, the ellipsis indicates where the sequence advances.

a) ... -7, -6, -5, -4, -3

We can observe that each term has a difference of one unit; if we subtract 1 from the term to the right, we obtain the following term

-3 -1 = -4

-4 -1 = -5

-7 -1 = -8

Therefore the mathematical operation is the subtraction.

b) $0. \sqrt{1}. \sqrt{4}, \sqrt{9}, \sqrt{16}, \sqrt{25}$ ...

In this case we can see more clearly the sequence when writing in this way

$0, \sqrt{1^2}. \sqrt{2^2}, \sqrt{3^2 } . \sqrt{4^2} , \sqrt{5^2}$

each term is found by adding 1 to the current term,

$\sqrt{(0+1)^2} = \sqrt{1^2} \\\sqrt{(1+1)^2} = \sqrt{2^2}\\\sqrt{(2+1)^2} = \sqrt{3^2}\\\sqrt{(5+1)^2} = \sqrt{6^2}$

Therefore the mathematical operation is the addition

c) $... \frac{-10}{2}. \frac{-8}{2}, \frac{-6}{2}, \frac{-4}{2}. \frac{-2}{2}. ...$

The recurrence term is unity, with the fact that the sequence extends to the right and to the left the operation is

To move to the right add 1

- $\frac{-10}{2} + 1 = \frac{-10}{2} - \frac{2}{2} = \frac{-8}{2}\\\frac{-8}{2} + \frac{2}{2} = \frac{-6}{2}$

To move left subtract 1

$\frac{-2}{2} - 1 = \frac{-4}{2}\\\frac{-4}{2} - \frac{2}{2} = \frac{-6}{2}$

Using the properties the mathematical sequence we find that the recurrence term is 1 and the operation for each sequence is

a) Subtraction

b) Sum

c) Sum

d) This case we have two possibilities

If we move to the right the sum

If we move to the left we subtract
