Find the nth term of 1,4,3,16,5,36,7

Mathematics

Answer:

64,9

Step-by-step explanation:

From my understanding the pattern would be:

Every other number is the next consecutive odd number,

( 1, 3, 5, 7 ) are all of the consecutive odds. (So the next odd is 9. )

That when we get to the part of where we get every other number for the remaining numbers, if you multiply the next even number by itself (square it).

4, 16, and 36 ( they are all perfect squares. )

They are the perfect squares of ( 2, 4, and 6) . So it makes sense that ( 8 ) is the next even number and you would square that and get ( 64 )

I hope this makes sense!!

Y(a -b) =c(y+ a); y

Ksivusya [100]

Answer:

y = ac / (a - b - c)

Step-by-step explanation:

y(a - b) = c(y + a)

Distribute

ay - by = cy + ac

Subtract cy from both sides

ay - by - cy = ac

Factor out y

y(a - b - c) = ac

Divide both sides by (a - b - c)

y = ac / (a - b - c)

When a decimal is written in word form, what indicates whether the number can be written as a mixed number or as a fraction less

vekshin1

9514 1404 393

Answer:

"and"

Step-by-step explanation:

Properly written, the word "and" separates the integer portion from the fractional portion of the number. If there is no "and", then there is no integer portion, so the number is a fraction less than 1.

Examples:

one and three tenths = 1 3/10

thirty-one thousandths = 31/1000

If m ACB = 48° and m CAB = 47°, is line BC a tangent to circle A?

muminat

Answer: No, because ABC is not a right angle.

Step-by-step explanation: In triangle ABC, the three angles add up to 180

So angle B = 180 - 48 - 47 = 85.

Most ATM’s require a 4-digit code using the digits 0-9 how many 4-digit codes can you use

Zolol [24]

10000 digits can be used for 4 digit A.T.M code.

Solution:

Given that A.T.M required 4 digit codes using the digits 0 to 9.

Need to determine how many four digit code can be used.

We are assuming that number starting with 0 are also valid ATM codes that means 0789 , 0089 , 0006 and 0000 are also valid A.T.M codes.

Now we have four places to be filled by 0 to 9 that is 10 numbers

Also need to keep in mind that repetition is allowed in this case means if 9 is selected at thousands place than also it is available for hundreds, ones or tens place .

First digit can be selected in 10 ways that is from 0 to 9.

After selecting first digit, second digit can be selected in 10 ways that is 0 to 9 and same holds true for third and fourth digit.

So number of ways in which four digit number is created = 10 x 10 x 10 x 10 = 10000 ways

Hence 10000 digits can be used for 4 digit A.T.M code.
