Round to the nearest given place.<br> 1.80431<br><br> thousandths
rodikova [14]
In order to round a number to the nearest thousandths, we have to check the number in the ten thousandths place:
1- If the number in the ten thousandths is less than 5, then the thousandths number will remain the same and all numbers after it will be converted to zeroes.
2- If the number in the ten thousandths is equal to or greater than 5, then the thousandths number will be incremented by 1 and all numbers after it will be converted to zeroes.

Applying this to the given number: 
<span>1.80431
</span>The number in the ten thousandths position is 3 which is less than 5.
Therefore, rounding <span>1.80431 to the nearest thousandths will be:
</span>1.80400 which is equivalent to 1.804

Plot point for negative 4 and negativie 1
Allushta [10]

Answer:

Step-by-step explanation:

(-4, -1) is what you asked to be plotted.

The first number is what number you go to on the x axis (horizontal).

The second number is what number you go to on the y axis (vertical).

I've attached a picture to help demonstrate. :)

The way I remember which comes first is to keep it alphabetical. X comes first, so go on the x axis first, then y

3x4²-(-6)²+4-6x4 <br>Need help!! Please!!
goblinko [34]
Assuming the x stands for multiplication... follow the ordering rules:

First let's take care of the exponents. 4²=16 and (-6)²=36. At the same time I will add some spacing between the terms:

3x16 - 36 + 4 - 6x4

Now do the multiplications:

48 - 36 + 4 - 24

The rest is just addition and subtraction

48 - 36 + 4 - 24 = -8

Perform the modular arithmetic. (7 · 15) (mod 4)
Reika [66]

We could do it by first writing

7\cdot15=(4+3)\cdot(4+11)=4^2+14\cdot4+33

so that

7\cdot15\equiv4^2+14\cdot4+33\equiv33\pmod4

and since 33=32+1=8\cdot4+1, we have

7\cdot15\equiv33\equiv1\pmod4

# # #

Alternatively, we can just compute the product and take it mod 4:

7\cdot15=105=104+1=26\cdot4+1

and so we get the same result of 1.
