Evaluate the limit 9n^3 + 5n - 2/2n^3

Mathematics
1 answer:
VikaD [51]3 years ago
4 0

Answer:

9/2    if  n goes to infinity  and that the 2n^3 is under the whole expression

Step-by-step explanation:

Let me clear this .

find  limit  (9n^3  + 5*n  - 2)/ (2n^3)

as n --> infinity

Did I put the parentheses in the right spot?

because if you leave it the way you did, then the whole expression goes to positive infinity as n goes to infinity  But I will do this with parentheses

so

find  limit  (9n^3  + 5*n  - 2)/ (2n^3)

simplify expression

limit   (9/2)  +   5/(2n^2)   -   1/(n^3)

=  (9/2)  + 0  - 0

=  (9/2)

Answer:

x+y= 59,  x-y= -13

Step-by-step explanation:

We know that x is the smaller number and y is the bigger number. We also know that the difference is 13, meaning x-y= -13. Since the sum of the two numbers is 59, x+y= 59

The temperature today was 10 degrees colder than twice yesterday's temperature, t.
Aneli [31]

Answer:  Today's temperature : 2t -10

Step-by-step explanation:

Hi, to write the expression of the statement given we have to analyze each phrase:

<em>Twice yesterday's temperature, t.</em> If t is yesterday’s temperature, twice that temperature equals 2t.

<em>The temperature today was 10 degrees colder than</em>: It means that we have to subtract 10 degrees :(-10)

Mathematically speaking:

Today's temperature : 2t -10

where t = yesterday's temperature

Feel free to ask for more if needed or if you did not understand something.

Hello, how was your day, help? ^ ^<br> solve for x
Natali5045456 [20]

Hi there!  

»»————- ★ ————-««

I believe your answer is:  

\boxed{x=100}

»»————- ★ ————-««  

Here’s why:  

  • Recall the Triangle Angle Sum Theorem: The three angles of all triangles add up to a sum of 180°.
  • We will set up an equation based on this and then solve.

⸻⸻⸻⸻

\boxed{\text{Solve for 'x':}}\\\\58 + 22 + x = 180\\-----------\\\rightarrow 80 + x = 180\\\\\rightarrow 80 - 80 + x = 180 - 80\\\\\rightarrow \boxed{x=100}

⸻⸻⸻⸻

»»————- ★ ————-««  

Hope this helps you. I apologize if it’s incorrect.
