5.	Tho first three terms or an AP are respectively (3y-1),(3y+5) and(5y+1), find the value ofy.
Answer» Answer: y=5 Step-by-step explanation: If a, B, c are THREE terms of an AP then b-a=c-b Using the above $(3y + 5 )- (3y - 1) = (5y + 1) - (3y + 5)$ $6 = 2y - 4$ $2y = 10$ $y = 5$

5.

Tho first three terms or an AP are respectively (3y-1),(3y+5) and(5y+1), find the value ofy.

Answer»

Answer:

y=5

Step-by-step explanation:

If a, B, c are THREE terms of an AP then

b-a=c-b

Using the above

$(3y + 5 )- (3y - 1) = (5y + 1) - (3y + 5)$

$6 = 2y - 4$

$2y = 10$

$y = 5$

6.

Simultaneous equation solve using Elimination method

Answer»

$\text{[math]}$

Solve the pair of linear ( simultaneous ) equation by the method of elimination by SUBSTITUTION :

2x + 7Y = 39

3X + 5y = 31

___________________________________

2x + 7y = 39 ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎... (1)

3x + 5y = 31 ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ... (2)

2x + 7y = 39

:. x = ( $\frac{39 — 7y}{2}$ )

Putting this value of x (2)

3 ( $\frac{39 — 7y}{2}$ ) + 5y = 31

117 — 21y + 10y = 62

— 11y = — 55

y = 5

Form (1) x $\frac{39 — 7(5)}{2}$

x = $\frac{4}{2}$

x = 2

For these questions you can go by concept of maxima and minima in calculus … But still there's a more EASY way which is known as AM GM inequality and it states that if there are TWO positive reals say a and b then their arithmetic mean is greater than or equal to their geometric mean … (Seems complex right but It's not at all!) Mathematically (a+b)/2 >( or equal to) root(a.b) for this question let's take the two terms individually then apply AM GM inequality (3tan^2x + 12/tan^2x)/2 > root (3tan^2x . 12/tan^2x) The tan^2x expression under the radical is cancelled and you get finally 3tan^2x+12/tan^2x > 2.root 36 Which shows that 3tan^2x+12/tan^2x > 12 So minimum possible value is 12 Note: “>” sign USED here represents greater than or equal to

The least value of sin2x-√3cot2x

Answer»

Step-by-step explanation:

What is the minimum value of 3tan^2x+12cot^2x?

Pursue your healthcare graduate degree online.

For these questions you can go by concept of maxima and minima in calculus …

But still there's a more EASY way which is known as AM GM inequality and it states that if there are TWO positive reals say a and b then their arithmetic mean is greater than or equal to their geometric mean … (Seems complex right but It's not at all!)

Mathematically (a+b)/2 >( or equal to) root(a.b)

for this question let's take the two terms individually then apply AM GM inequality

(3tan^2x + 12/tan^2x)/2 > root (3tan^2x . 12/tan^2x)

The tan^2x expression under the radical is cancelled and you get finally

3tan^2x+12/tan^2x > 2.root 36

Which shows that 3tan^2x+12/tan^2x > 12

So minimum possible value is 12

Note: “>” sign USED here represents greater than or equal to
