If Alina wrote the last term as 3y3, which must be the first term of her polynomial in standard form

Answers

Answer:

-8x2y

Step-by-step explanation:

Answer:

-8x^2y

Step-by-step explanation:

First collect like terms of xy^2 and 4xy^2(since their variables and deggres are the same) and you get: 5xy^2 - 2x^2y + 3y^3 - 6x^2y

Then collect like terms of -2x^2y and -6x^2(since their variables and deggres are the same) and you get: 5xy^2 - 8x^2y + 3y^2

The problem states "which must be the first term of her polynominal in standard form?"

That means that the polynominal Alina is talking about is -8x^2y.      

can someone tell me what’s the answer please ?!

Answers

Answer:

no se

Step-by-step explanation:

I believe the answer is A : y=2x+1

Explanation: The Y-intercept goes through 1 not -1 so you know the last part will be +1. That limits it to A and B. Secondly, It goes rise/run. So look at how the line goes through points. For example From the intercept to the next line. It goes up 2 over one. So 2/1 which is 2. This way it is Y=2x+1! Hope this helps!

a water bottle holds 2 litres. A leak in the bottle means 25ml drops out each day. How many days will it take until the bottle is empty? please

Answers

Answer:

80

Step-by-step explanation:

2 litres = 2000 ml

2000/25 = 80

80 days

Answer:

80 days

Step-by-step explanation:

First convert 2 litres into millilitres:

2 × 1000 = 2000 ml

To find out how many days it would take until the bottle is empty you have to divide 2000ml by 25ml

2000ml / 25ml = 80 days

What is the growth rate of the function f(x)=1.35x?

Answers

Answer:

x=0

Step-by-step explanation:

hope this helps!

The given function is linear. Thus its rate is constant.

The rate of given function is 1.35 per unit growth in input.

Given that:[tex]f(x) = 1.35x[/tex]To find:

Rate of the function

What is linear function?


A linear function is a function whose graph is a straight line.

Rate of linear functions:

Rate of a linear function is constant.

Finding the growth rate:

Let we increase the input x with unity, then:

[tex]f(x) = 1.35x\\ f(x+1) = 1.35(x+1)\\ [/tex]

The difference in functions' output is the growth per unit growth in input:
[tex]f(x+1) - f(x) = 1.35(x+1) - 1.35(x) = 1.35[/tex]

Thus, the rate of the growth of function is 1.35 per unit growth in input(since the rate is constant for linear function, thus this rate is true for all values of x).

[tex]x^2 + 8^2 = 15^2\\x^2 + 64 = 225\\x^2 = 161\\x = \sqrt{161}[/tex]

Answer:

Pythagorean Theorem

Step-by-step explanation:

You want to use Pythagorean Theorem on right degree triangles. Using the formula:

a^2 + b^2= c^2, where a and b are the legs while c is the hypontuse( the slanted side of the triangle and the longest.) let plug in the numbers.

8^2+ x^2=15^2; Subsitution

64+x^2=225: Equalvelent Equation

x^2= 161: Subtraction Poperty of Equality

sqr root of 161= 12.688 or 12.69 or 12.7

x=12.689 ( if rounded to nearest hundredth) or x=12.7 if rounded to nearest tenth.

Is 10 a perfect square? Is 100 perfect square? Explain

Answers

10 is not a perfect square however 100 is. This is because a square is defined as numbers that are the product of another whole number when multiplied by itself. So, 10x10=100, making 100 a perfect square. However, no number multiplied by itself equals 10, meaning 10 is NOT a perfect square.

Answer:

No, 10 is not a perfect square.

Yes, 100 is a perfect square.

Step-by-step explanation:

10 is not because  in order for a number to be a perfect square, you have to see if the numbers that are multiplied to get it are the same.

100 is because 10 x 10 <---- exact same number being mutiplied.

A rectangular gardien has a perimeter of 24 feet. The length is three less
than twice the width. Find the length

Answers

Answer:

So basically you have to find the width and the length that fits based on what they're giving you.

A basic perimeter equation= P=2L+2W

24=2W+2L

divide by 2 for each variable

so

12=2w+l

6=w+l

so, w+l could be 2+4, 3+3, or 1+5. now, if you input each of these into the equation

(2w)-3=l

so 2 could be 1,2,3,4, or 5.

2(1)-3=-1.... so it can't be w=1 l=5

2(2)-3=1... it can't be w=2 l=4

2(3)-3=3.... the length is 3

SO

you're answer for the length is 3
