The definite integral is defined to be exactly the limit and summation that we looked at in the last section to find the net area between a function and thex-axis. Also note that the notation for the definite integral is very similar to the notation for an indefinite integral.

Let age of son = x yrsThen age of father = 3x - 2

Given,x + (3x - 2) = 544x = 54 +24x = 56x = 14

Age of son x = 14 yearsAge of father (3x - 2) = 3*14 - 2 = 40 years

Thanks

hey the answer is 25/7 flowers.

bhai lakhan select my answer as best

20)300+60+0.3+0.009=360.309

8 is the correct answer.

1 pot has 2 flowers.7 pots have (2*7) = 14 flowers

Here, A pot has 2 flowers in it, so that doesn't mean that the remaining pots too have 2 flowers each..

Please don't use Cos and sin.

I want answer in a simple way.

but that can be done through triangles. ,in which I will use the criteria of INCENTRE .and then I will derive it..

area=√s(s-side1)(s-side2)(s-side3)

I am asking the derivation of Hero 's Formula .

Not the formula.

let rahul's age be xthen his mother's age=4x-54x-5=394x=44x=11

Factors of 42: 1, 2, 3, 6, 7, 14, 21,42.

Thefactors of 96. Answer : 1,2,3,4,6,8,12,16,24,32,48,96,

Factors of 28- 1, 2, 4, 7, 14, 28

Let mother's age be xPratima's age=x/2 -6(=y)x+x/2 -6=573x/2=63x=42(mother's age)42/2-6=21-6=15(Pratima's age)Difference=42-15=27 years

P = M/2 - 6 so 2P - M = -12 P + M = 57 2P - M + P + M = 57 - 12 3P = 45 P = 15 M = 42 M - P = 42 - 15 = 27

three points are collinear if x1(y2- y3) + x2(y3- y1) + x3(y1- y2) = 0

here, x1= 1 , x2= 5 , x3= 9 y1= - 1 , y2= 2 , y3= 51 (2 - 5) + 5 (5 + 1) + 9 (- 1 - 2) = 0- 3 + 30 - 27 = 00 = 0

given : sunil's age is 48 years ..........(1)

let sunil's daughters age be x

according to the question ,

sunil's age = 5x-7 ............(2)

equating both the equations

5x-7 = 48

5x=48+7

5x = 55

x=11

hence sunil's daughter's age is 11 years

Let age of son = xThen age of father = 5x - 3

After 5 years age of son = x + 5

Then after 5 age of father= 3(x + 5) + 3

So, according to the given condition5x - 3 + 5 = 3(x + 5) + 35x + 2 = 3x + 15 +32x = 18 - 22x = 16x = 16/2 = 8

Therefore age of son = 8 years

Your father's age is 4x-3 of your age.

thanks

81 is the right answer

3 to the power of 4 is the correct answer

-81 is right answer

-81 is the correct answer of the given question

(-3)(-3)-(3)(-3)(9)(9)81

81 is the right answer

81 is correct answer.

(-3)×(-3)×(-3)×(-3) = (-3)4

81 is the right answwe

The exponential is (-3)power 4

(-3)×(-3) ×(-3)×(-3)= (-3)^4

-3 power is 4 is correct answer

(3)the power 4 of exponents form.

x - 1 + 1/x = 6x^2 - x + 1 = 6xx^2 - 7x + 1 = 0

According to the Quadratic Formula, x , the solution for Ax2+Bx+C = 0 , where A, B and C are numbers, often called coefficients, is given by : - B ± √B^2-4ACx = ———————— 2A

Accordingly, B^2 - 4AC = 49 - 4= 45

Applying the quadratic formula : 7 ± √45 x = ————— 2

Two real solutions: x = (7+√45)/2= (7+3√ 5 )/2orx = (7-√45)/2 = (7-3√ 5 )/2

81^³ is the correct answer of the given question

81^3 is the correct answer of the given question

Principal + 8% p.a. interest on principal for n years = 180 …….. (1)

Principal + 4% p.a. interest on principal for n years = 120 ……… (2)

Subtracting equation (2) from equation (1), we get

4% p.a. interest on principal for n years = Rs.60.

Now, we can substitute this value in equation (2),

i.e Principal + 60 = 120

= Principal = Rs.60.

We know that SI = , where p is the principal, n the number of years and r the rate percent of interest.

In equation (2), p = Rs.60, r = 4% p.a. and the simple interest = Rs.60.

Therefore, 60 =(60*n*4)/100

=> n = 100/4 = 25 years.

Interest = PRT

Given that interest for 5 years at 10% is Rs 196 less than 4 years at 16%

⇒ P(0.16(4) - P(0.1)(5) = 196

Solve for P:

P(0.16(4) - P(0.1)(5) = 196

0.64P - 0.5P = 196

0.14P = 196

P = Rs 1400

Answer: The principal amount is Rs 1400
