The rule to find the term is: y=225-4x
you want to know the 82nd term which occurs when x=82 therefore
y = 225-(4 x 82) = -103

82nd term = -103

How to use synthetic division to show how to methodically obtain the factors from the polynomial 2x^5+6x^4-42x^3-86x^2+192x+360

MA_775_DIABLO [31]

Okay so first you need to find your prrs which in this case would be all factors of 360 and all of the factors of 360 divided by two since the factors of two are two and one. (Which I pulled from the first x’s coefficient)

Then you do Descartes law to find out how many positives or negatives in this equation. There looks to be 2 positives and 3 or 0 negatives. Since there are guaranteed positives I’d recommend doing those first. Start from the lowest number since that’s easier and more mathematically correct and do synthetic division. (x+1) The resulting polynomial should be factorable and of not then try to synthetically divide again.

What is $0.1369 rounded to the nearest cent

makvit [3.9K]

Ok, what is $0.1369 rounded to the nearest cent?

100 cents make a dollar which means the most possible cents not making a dollar is 99 cents

So that means you leave the first two decimals alone and focus on the last two.

What is 69 closer to? 70 or 60? Well, its larger than 65 which is the halfway point so its closer to 70

Is 70 closer to 0 or 100? Well, since 70 is past the halfway point which is 50, its closer to 100.

Think of 3 as 0 and the next number up which is 4 as 100, well, since 70 is closer to 100 than 0, its closer to 4.

So That means that 0.1369 rounded to the nearest cent is $0.14

Your answer rounded is $0.14

The jeweler buys gold for 1235.55 per ounce and resells it for 1376.44 per ounce how much profit does the jeweler make from buyi

AnnZ [28]

Profit made by jeweler from buying and reselling ounces of gold is 140.89 per ounce

<u>Solution:</u>

Given that

Price at which jeweler buy gold = 1235.55 per ounce

Price at which jeweler resells gold = 1376.44 per ounce

We need to calculate profit.

Buying price of 1 ounce of gold = 1235.55

Reselling price of 1 ounce of gold = 1376.44

<em>Profit = Reselling price – buying price</em>

So profit on 1 ounce of gold = 1376.44 – 1235.55 = 140.89

Hence profit made by Buying and Selling gold will be 140.89 per ounce

im stupid. honestly. just help me pls. this is probably really easy but i aint done any maths in over a month so ion remember ho

Answer:

19 coins

Step-by-step explanation:

We know that mean is the sum of all the elements divided by the number of elements there are: m = t/n, where m is the mean, t is the total sum, and n is the number of elements.

Here, we are given the mean number of coins for all 27 + 18 = 45 children is 16, so m = 16 and n = 45. Then:

m = t/n

16 = t/45

t = 720

This t means that the total number of coins that all the boys and girls have is 720 coins.

Now, we also know the mean number of coins for the boys only, which is 14. Since there are 27 boys, then:

m = t/n

14 = t/27

t = 378

This t means the total number of coins all the boys have.

Subtracting 378 from 720, we get 342, which is the total number of coins the girls have. We also know there are 18 girls, so:

m = t/n

m = 342 / 18 = 19

Thus, the mean is 19 coins.
