If a and b are positive real numbers, then a+b≥2ab−−√.

I know how to do the direct proof, but in this case, I want to try PROVING it by contradiction. I have tried MANIPULATING the inequality a+b<2ab−−√ after making the assumption that a,b>0 to GET a contadiction a,b≤0.

a+ba2−2ab+b2(a−b)2<2ab−−√<0<0,

ong>Answer:

Given INFO : the SUM of three numbers in arithmetic progression is -8 and the PRODUCT of these terms is 1.

To find : the numbers

solution : let (a - d), a and (a + d) are three terms in arithmetic progression.

sum of three terms = . 8

→ (a - d) + a + (a + d) = -8

+ 3a = -8

→ a = -8/3

New product of terms = 1

→ (a - d)a(a + d) = 1

→ (a° - ad?) = 1

→(-8/3) - (-8/3)d² = 1

→-512/27 + 8d2/3 = 1

=-512/27 + 8 d?/3 = 1

→ 8d?/3 = 1+ 512/27 = 539/27

→d = tv(539/72) = ±2.74

therefore the numbers are ;

- d = -8/3 - 2.74 = -5.406

a = -8/3 = -2.67

a +d = -8/3 + 2.74 = 0.073 =

Solution:

We know that,

sec2θ – tan2θ = 1

(sec θ + tan θ) (sec θ – tan θ) = 1

(7) (sec θ – tan θ) = 1 …[sec θ + tan θ = 7; (Given)

∴ sec θ – tan θ = 17Solution:

We know that,

sec2θ – tan2θ = 1

(sec θ + tan θ) (sec θ – tan θ) = 1

(7) (sec θ – tan θ) = 1 …[sec θ + tan θ = 7; (Given)

∴ sec θ – tan θ = 17Solution:

We know that,

sec2θ – tan2θ = 1

(sec θ + tan θ) (sec θ – tan θ) = 1

(7) (sec θ – tan θ) = 1 …[sec θ + tan θ = 7; (Given)

∴ sec θ – tan θ = 17The process by which a living being utilizes the food to get energy is called RESPIRATION.

ANSWER

Height of pole=AB=6 m

Length of shadow of pole =BC=4 m

Length of shadow of TOWER=EF=28 m

In △ABC and △DEF

∠B=∠E=90

∘

both 90

∘

as both are vertical to ground

∠C=∠F (same elevation in both the cases as both shadows are cast at the same time)

∴△ABC∼△DEF by AA similarity criterion

We KNOW that if two triangles are similar, RATIO of their sides are in proportion

So,

DE

⇒

⇒DE=6×7=42 m

Hence the height of the tower is 42 m
