Answer:

1/(k^2)

Step-by-step explanation:

Because the k's are above one another in the fraction format, using exponent rules you would subtract the top number exponents with the bottom number exponents (note do not do anything with the letter k). 5-7= -2, and k^-2 is the same as 1/(k^2).

Hope you have a great day and this helps! :)

Count the number of 5-digit numbers (in the decimal system; integers from 10000 to 99999) which are not divisible by 11.
Alexxandr [17]

Answer:

So total number which is not divisible by 11 = 89999-8181 = 81819  

Step-by-step explanation:

We have to find the total numbers which are not divisible by 11 from 10000 to 99999

Total number from 10000 to 99999 = 99999-10000+1=90000

Just after 10000 the number which is divisible by 11 is 10010

And just below 99999 the number which is divisible by 11 is 99990

Using AP formula

T_N=a+(n-1)d, here a is first term, d is common difference and n is number of terms

So 99990=10010+(n-1)11

n-1 = 8180

n= 8181

So total number which is not divisible by 11 = 90000-8181 = 81819

if 22000 pots with 15 seeds each are used in a nursery, how many total seeds, in scientific notation?
kipiarov [429]

Write the total number of seeds in scientific notation

Given:

Number of pots = 22,000

Number of seeds = 15

<em>Total number of seeds = Number of pots × Number of seeds</em>

= 22,000 × 15

= 330,000

Scientific notation is written in multiples of 10

  • Count the number of digits
  • Insert a decimal point between the first digit and other digits
  • count the number of digits after the first digits
  • multiply by 10 raise to the power of number of remaining digits after first digits

= 3.30000 × 10^5

Therefore,

the total number of seeds in

scientific notation is 3.30000 × 10^5
