Simplify√216 -5√6+√94 plz answer fast​

Answer»

Answer:

√216-5√6+√294-3/√6 = 15 √6 / 2

Step-by-step explanation:

√216-5√6+√294-3/√6

first simplify √216 & √294 & 3/√6

√216 = √6*6*6 = 6√6

√294 = √7*7*6 = 7√6

3/√6 = 3√6/6 = √6/2

using SIMPLIFIED values of √216 & √294 & 3/√6

= 6√6 - 5√6 + 7√6 - √6/2

= √6 ( 6 - 5 + 7 -1/2)

= √6 ( 8 -1/2)

= √6 (15/2)

= 15 √6 / 2

Answer»

Step-by-step EXPLANATION:

TSA of cylinder =2πr(r+h)

r=56 cm

h=1.4 m=140cm

TSA=2*22/7*56(56+140m)

=44*8(196)

=68,992 cm^2

in m =6.8992m^2

So,metal sheet REQUIRED is 6.8992m ^2

Find the nth and the sum of the first n term of progression 8,98,998,9998....in term of n.​

Answer»

Answer:

nth term = 10^n - 2 ; Sum of n terms = \frac{10(10^{n} - <klux>1</klux>)}{9}  - 2^{n}

Step-by-step explanation:

sequence : 8,98,998,9998 ... n terms

this can be WRITTEN as : (10-2) , (100-2) , (1000-2) , (10000-2) ...

1st term = 10 - 2

2nd term = 100 - 2 = 10^2 - 2

3rd term = 10^3 - 2

so, nth term = 10^n - 2

sum of n terms = 8+98+998+9998+ ... = (10-2)+(100-2)+(1000-2)...n terms

separating the terms, we get :

S(n) = (10+100+1000+10000+....) - (2+2+2+2+...)

we see, the first term is a geometric progression, with first term = 10, and ratio = 10

so, S(n) = sum of GP - 2(n)

->sum of GP : s(n) = a*(r^n-1) / (r-1)   =  10*(10^n-1) / (10-1)  = 10(10^n - 1) / 9

so we get :

S(n) = \frac{10(10^{n} - 1)}{9}  - 2^{n}

NO SPAMThe median of the numbers 4 , 15 ,19 , 21 , 6 is(a) 19(b) 15(c) 15.5(d) 17​

Answer»

Answer:

b) 15

Step-by-step explanation:

SOLUTION:

Numbers => 4, 15, 19, 21, 6

Let's arrange them in ascending or descending order,

4, 6, 15, 19, 21

Count of numbers, n = 5

Median = (n + 1)/2 = (5 + 1)/2 = 6/2 = 3rd term which is 15

(b)15 is the correct answer.

Extra Information:

Median is the VALUE of the middle most item when all the items are in the order of magnitude.

MEAN=> In mean we add all the observations and divide with the number of observations given.

Mode=> It is the value which occurs the most times in the LIST of observations.

Range=> It is the difference between the largest and smallest value from the observations given.
