5.	If costhita =3/5 then what is the value of 6tanthita-5costhita
Answer» $\bigstar$ Answer : 5 is the answer $\bigstar$ Step-by-step EXPLANATION : $\star$ GIVEN $cos\theta=\frac{3}{5}$ $\implies \frac{adj.side}{hypotenuse}=\frac{3}{5} \\\\$ $\star$ Let third side be OPPOSITE side. => By using Pythagoras THEOREM, $\star$ opp²+adj²=hyp² => opp²=5²-3² => opp²=25-9 =>opp²=16 => opp=4 $\star$ So , $6tan\theta-5cos\theta\\\\\implies 6.\frac{opp.side}{adj.side}- 5.\frac{adj.side}{hyp.}\\\\ \implies 6.\frac{4}{3}-5.\frac{3}{5}\\\\ \implies 2.4 -3\\\\\implies 8-3\\\\\implies 5$

5.

If costhita =3/5 then what is the value of 6tanthita-5costhita

Answer»

$\bigstar$ Answer :

5 is the answer

$\bigstar$ Step-by-step EXPLANATION :

$\star$ GIVEN $cos\theta=\frac{3}{5}$

$\implies \frac{adj.side}{hypotenuse}=\frac{3}{5} \\\\$

$\star$ Let third side be OPPOSITE side.

=> By using Pythagoras THEOREM,

$\star$ opp²+adj²=hyp²

=> opp²=5²-3²

=> opp²=25-9

=>opp²=16

=> opp=4

$\star$ So ,

$6tan\theta-5cos\theta\\\\\implies 6.\frac{opp.side}{adj.side}- 5.\frac{adj.side}{hyp.}\\\\ \implies 6.\frac{4}{3}-5.\frac{3}{5}\\\\ \implies 2.4 -3\\\\\implies 8-3\\\\\implies 5$

Ques-6 Find the cost of leveling a ground in the form of a triangle with sides 16m,12m and 20m at Rs.4 per sq.meter

Answer»

ANSWER:

RS 384

Explanation:

Area of a triangle =

$\sqrt{s(s - a)(s - b)(s - c)}$

where sis the semi-perimeter of the triangle

Perimeter of the given triangle = (16+12+20) m

= 48 m

So, semi-perimeter = (48/2) m = 24 m

So, area of the triangle =

[tex] \sqrt{s(s - a)(s - b)(s - c)} [/tex]

= [tex] \sqrt{24(24-16)(24-12)(24-20)} [/tex]

= [tex] \sqrt{24×8×12×4} [/tex]

= [tex] \sqrt{9216} [/tex]

= 96 cm^2

Cost of leveling the FIELD = Rs (96×4)

= Rs 384

Hope it helps.......

If the sum of three numbers in AP is 9 and their product is 24 then the number is what

Answer»

Answer:

2,3,4

Step-by-step EXPLANATION:

LET the numbers be a-d,a,a+d

Given SUM is 9

a-d+a+a+d=9

3a=9

a=9/3

a=3

Given product is 24

(a-d)a(a+d)=24

(a^2-d^2)a=24

(3^2-d^2)3=24

(9-d^2)3=24

9-d^2=24/3

9-d^2=8

d^2=9-8

d^2=1

d=+or - 1

if d=1

a-d=3-1=2

a=3

a+d=3+1=4

if d=-1

a-d=3-(-1)=3+1=4

a=3

a+d=3+(-1)=3-1=2

The numbers are 2,3,4

Answer» Answer: x^2 - 26x + 160 = 0 look for the coefficient of x^2 and if it is not 1 then divide the equation by the coefficient of x^2 so as to make it 1. next shift the constant to right hand side take the coefficient of x divide it by 2, then square it and add to both sides of the given equation. then solve for x in the given example, a = 1, B = -26 and C = 160 [ a and b are the coefficients of x^2 and x respectively and c is the constant ] x^2 - 26x + (13)^2 = -160 + (13)^2 => x^2 - 26x +169 = -160 + 169 => x^2 - 26x + 169 = 9 => (x - 13)^2 = 9 => x - 13 = √9 => x - 13 = +3 and -3 => x = 3 + 13 = 16 and x - 13 = -3 => x = 10 therefore x = 16 and x = 10 are the solutions

X^2-26x+160=0 completing the square

Answer»

Answer:

x^2 - 26x + 160 = 0

look for the coefficient of x^2 and if it is not 1 then divide the equation by the coefficient of x^2 so as to make it 1.

next shift the constant to right hand side

take the coefficient of x divide it by 2, then square it and add to both sides of the given equation.

then solve for x

in the given example, a = 1, B = -26 and C = 160

[ a and b are the coefficients of x^2 and x respectively and c is the constant ]

x^2 - 26x + (13)^2 = -160 + (13)^2

=> x^2 - 26x +169 = -160 + 169

=> x^2 - 26x + 169 = 9

=> (x - 13)^2 = 9

=> x - 13 = √9

=> x - 13 = +3 and -3

=> x = 3 + 13 = 16 and x - 13 = -3 => x = 10

therefore x = 16 and x = 10 are the solutions

√3x^2+2√2x-2√3=0 by discriminant

Answer»

AnsWer :

32.

SolutioN :

We have, EQUATION.

$\tt \dagger \: \: \: \: \: \sqrt{3} {x}^{2} + 2 \sqrt{2} x - 2 \sqrt{3} = 0.$

# Compare with General Equation.

$\tt \dagger \: \: \: \: \: a {x}^{2} + bx + c = 0.$

Where as,

a = √3.
b = 2√2.
c = - 2√3.

Now,

D ( Discriminant )

$\tt \dagger \: \: \: \: \: D = {b}^{2} - 4ac.$

$\tt : \implies D = { \big(2 \sqrt{2} \big) }^{2} - 4 \times \sqrt{ 3} \times - 2 \sqrt{3} .$

$\tt : \implies D = 8 + 24.$

$\tt : \implies D = 32.$

Therefore, the value of discriminant is 32.

Some INFORMATION :

† Condition 1.

D > 0.
ROOTS are Real.

† Condition 2.

D < 0.
Roots are unreal.

† Condition 3.

D = 0.
Both Roots are equal.

Answer» Answer: In mathematics, a RATIONAL number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q.[1] Since q may be EQUAL to 1, every integer is a rational number. The set of all rational numbers, often referred to as "the RATIONALS", the field of rationals or the field of rational numbers is usually denoted by a boldface Q (or blackboard bold {\displaystyle \mathbb {Q} }\mathbb {Q} , Unicode ℚ);[2] it was thus denoted in 1895 by Giuseppe Peano after quoziente, Italian for "quotient".
