5.

√limit-22 x^2019 dx is equals to

Answer»

$\implies\displaystyle\int\limits^{ \sf2}_{ \sf - 2} \sf{x}^{2019} dx$

We KNOW that :-

$\sf\implies\displaystyle\int\limits^{ \sf \: n}_{ \sf \: m} \sf \: f(x)dx = g(x) {\bigg]}^{n}_{ m} = g(n) - g(m)$

$\implies\displaystyle\int\limits^{ \sf2}_{ \sf - 2} \sf{x}^{2019} dx = \dfrac{1}{2020} { \large \: x}^{2020} {\bigg]}^{2}_{ - 2}$

Now PUT the value of UPPER limit and LOWER limit.

$\sf\implies \dfrac{1}{2020} \: { \large \: x}^{2020} {\bigg]}^{2}_{ - 2} = \dfrac{1}{2020} \bigg[ {2}^{2020} - { ( - 2)}^{2020} \bigg]$

$\sf\implies \dfrac{1}{2020} \bigg[ {2}^{2020} - \bigg( { {( - 1)}^{2020} \times ( 2)}^{2020} \bigg) \bigg]$

$\sf\implies \dfrac{1}{2020} \bigg[ {2}^{2020} - \bigg( { 1\times ( 2)}^{2020} \bigg) \bigg]$

$\sf\implies \dfrac{1}{2020} \bigg({2}^{2020} - {2}^{2020} \bigg)$

$\sf\implies \dfrac{1}{2020} \times 0$

$\sf\implies 0$

8.

the length and breadth of a rectangular field are in the 7:4 ,if it's perimeter is 440. Find it's length and breadth.

Answer»

Answer:

Given : Perimeter = 440 m

Let the length of RECTANGULAR field = lx and breadth = 4X

2(l + B) = Perimeter

2(7x + 4x) = 440 m

2(11x) = 440 m

22x = 440 m

x = 440/22

x = 11 m

∴ Length = 7x = 7 x 11 = 77 m

Breadth = AX = 4 x 11 = 44 m

Cost of fencing per m = ₹150

Cost of fencing 440 m = ₹150 x 440 = ₹66,000

A boat covers a certain distance downstream in 2 hours. It covers the same distance upstreamin 2 hours. The speed of the boat in still water is 18 km/h. Find the speed of the water,Also find the distance covered by the boat.

Answer»

Step-by-step explanation:

16). Let BREADTH is B

then length = b+7

area of rectangle = L×B

= (B+7)×B

=B2 +7B

new breadth= b+3

new length=b+7-4=b+3

area =L×B

=(b+3)×(b+3)

=(b+3)2

(=a+b)2= a2+2ab+b2)....1

now put the value of a =b and value of b = 3 in equation 1

=b2+6b+9

acc.. to question

ORIGINAL rectangle = new rectangle

b2+7b = b2+ 6b+9

b2 +7b-b2-6b=9

b = 9

HENCE breadth = 9

now putt the value of b in ( b + 7)

= 9+7

=16

L =16

so 78=n/2{48+(n-1)×(-3)}

on SOLVING we GET

52=16n+n-n^2

n^2-17n+52=0

on factorization we get

(n-13)(n-4)=0

n=13 or 4

ANSWER:

Let X,Y and Z be three jointly continuous random variables with joint PDF

fXYZ(x,y,z)=⎧⎩⎨⎪⎪13(x+2y+3z)00≤x,y,z≤1otherwise

Find the joint PDF of X and Y, fXY(x,y).Let X,Y and Z be three independent random variables with X∼N(μ,σ2), and Y,Z∼Uniform(0,2). We also know that

E[X2Y+XYZ]=13,E[XY2+ZX2]=14.

Find μ and σ.Let X1, X2, and X3 be three i.i.d BERNOULLI(p) random variables and

Y1=max(X1,X2),Y2=max(X1,X3),Y3=max(X2,X3),Y=Y1+Y2+Y3.

Find EY and VAR(Y).Let MX(s) be finite for s∈[−c,c], where c>0. Show that MGF of Y=aX+b is given by

MY(s)=esbMX(as),

and it is finite in [−c|a|,c|a|]Let Z∼N(0,1) Find the MGF of Z. Extend your result to X∼N(μ,σ)

Calculate the total surface area and lateral surface areaof the given cylinder;h=7cm5 Marksr=7cm

Answer»

$\sf{\underline{Given}}$

Height of the cylinder (h) = 7 cm
Radius of base (R) = 7 cm

$\sf{\underline{To\:Find}}$

Total Surface AREA
LATERAL Surface Area

$\sf{\underline{Solution}}$

Height = 7 cm

Radius of base = 7 cm

$\sf{LSA\:of\:a\:cylinder = 2\pi rh \:sq.units}$

= $\sf{LSA = 2\times \dfrac{22}{7}\times(7)^2\times7}$

= $\sf{LSA = 1078\:cm^2}$

Now,

$\sf{TSA\:of\:a\:cylinder = 2\pi r(r+h)\:\:sq.units}$

= $\sf{TSA = 2\times\dfrac{22}{7}\times7(7+7)}$

= $\sf{TSA = 44\times7\times14}$

= $\sf{TSA = 4312\:cm^2}$

_________________________________________

$\sf{\underline{More\:Information}}$

$\sf{Volume\:of\:cylinder = \pi r^2h\:\:cu.units}$
$\sf{TSA\:of\:a\:cylinder = 2\pi r(r+h)\:\:sq.units}$
$\sf{LSA\:of\:a\:cylinder = 2\pi rh \:sq.units}$

$\sf{\underline{Note}}$

LSA stands for Lateral Surface Area.
TSA stands for Total Surface Area.
Lateral Surface area is also known as Curved Surface Area (CSA).
