First, move 9x^2 to the right:

7y^2 = 42 - 9x^2

Then, divide 7 on both sides:

y^2 = 6 - 9/7 * x^2

What is the probability of drawing a 6 or a king,​
Thepotemich [5.8K]

Answer:

Step-by-step explanation:

You didn't give much information, and it depends if your deck of cards includes a pair of Jokers.

There are 52 cards in a deck, not including Jokers, otherwise there are 54.

In a non-Joker deck the chances of drawing a King or 6 is 8/52 or roughly 15.4% in a deck with 2 Jokers your chance is 14.8%.

Answer:

\frac{2}{5}j^{2}

Step-by-step explanation:

Let

j ------> the number

we know that

The square of a number is equal to multiply the number by itself

so

The square of j is

j*j=j^{2}

so

Two-fifths of the square of a number j is the same that multiply the fraction 2/5 by the square of j

\frac{2}{5}j^{2}

NEED HELP FAST PLEASE<br> Evaluate the limit.<br><br> a.4<br> c.1<br> b.2<br> d.limit does not exist
BlackZzzverrR [31]
We have the following limit:
 (8n2 + 5n + 2) / (3 + 2n)
 Evaluating for n = inf we have:
 (8 (inf) 2 + 5 (inf) + 2) / (3 + 2 (inf))
 (inf) / (inf)
 We observe that we have an indetermination, which we must resolve.
 Applying L'hopital we have:
 (8n2 + 5n + 2) '/ (3 + 2n)'
 (16n + 5) / (2)
 Evaluating again for n = inf:
 (16 (inf) + 5) / (2) = inf
 Therefore, the limit tends to infinity.
 Answer:
 
d.limit does not exist
