The point of inflection of f(x)=x^6 is​

Answer»

align="absmiddle" alt="\sf\huge\bold{\underline{\underline{{Solution}}}}" class="latex-formula" id="TexFormula1" src="https://tex.z-dn.net/?f=%5Csf%5Chuge%5Cbold%7B%5Cunderline%7B%5Cunderline%7B%7BSolution%7D%7D%7D%7D" title="\sf\huge\bold{\underline{\underline{{Solution}}}}">

For POINT of inflexion the function has neither maxima nor minima this is called point of inflexion.

Concept

Here ,f(x) is given so,we FIRST find its derivative and make equal to zero and hence find value of x and then find its double DERIVATIVES and put value of x here.If the function is greater than zero then it's minima or if less than zero then it's maxima or if zero comes then it's point of inflexion.

↦f(x)= x⁶

finding derivatives

↦f'(x) or dy/dx = 6x⁵

↦f'(x)=0

↦6x⁵=0

↦x⁵=0

↦x=0

finding second derivatives

↦f"(x)= 6×5x⁴

↦f"(x)= 30x⁴

put x=0

f"(x) at x=0

↦30(0)⁴=0

Zero SIGNIFIES point of inflexion.

Hence,the function is point of inflexion at x=0.

V) In the equation 2X+ 3y=11 ,find the value (a)x if y=5 and (b) y if x=4​

Answer»

ong>Answer:

(a) -2 and (b) 1

Step-by-step explanation:

(a) Now if y = 5 , then

2X + 3(5) = 11

2x + 15 = 11

2x = 11 - 15

2x = -4

x = -4/2

x = -2

(b) Now if x = 4 , then

2(4) + 3Y = 11

8 + 3y = 11

3y = 11 - 8

3y = 3

y = 3/3

y = 1

Fig. 5.5 20. In a potato race, a bucket is placed at the starting point, which is 5 m from the first potato,and the other potatoes are placed 3 m apart in a straight line. There are ten potatoes in theline (see Fig. 5.6).a5 m3m3 mFig. 5.6A competitor starts from the bucket, picks up the nearest potato, runs back with it, dropsit in the bucket, runs back to pick up the next potato, runs to the bucket to drop it in, andshe continues in the same way until all the potatoes are in the bucket. What is the totaldistance the competitor has to run?(Hint: To pick up the first potato and the second potato, the total distance (in metres)run by a competitor is 2 x 5+2 (5+3)]​

Answer»

ong>Answer:

The distances of potatoes from the bucket are 5,8,11,14…

Distance RUN by the competitor for collecting these potatoes are two times of the distance at which the potatoes have been kept. Therefore, distances to be run are

  smallest = 1235

c. greatest = 6321

  smallest = 1236

d. greatest = 9831

  smallest  = 1389

Step-by-step explanation:

For WRITING the greatest number, arrange them in descending ORDER

and for smallest arrange them in asscending order.

Exception in case of 0

for eq: in a. if we write 0357 its not a 4 DIGIT number so we write 3057

Find the equation of the circle which has the points (-2,3) and (0, -1) as opposite ends of a diameter.​

Answer»

ong>ANSWER:

x² + y² + 2x - 2y - 3 = 0

Step-by-step explanation:

Mid point of the line joining them gives the RADIUS of the circle.   USING mid-point FORMULA,

Co. of radius = ((0+(-2))/2 , (-1+3)/2 )

                     = (-1 , 1)

Using distance formula,

Radius = distance b/w (-1, 1) and (0,-1)

            = √(-1 - 0)² + (1 - (-1))²

            = √5

Thus,  eq. of the circle is:

⇒ (x - x₁)² + (y - y₁)² = r²

⇒ (x - (-1))² + (y - 1)² = (√5)²

⇒ x² + 1 + 2x + y² + 1 - 2y = 5

⇒ x² + y² + 2x - 2y - 3 = 0

In figure,ABPC is a quadrant of a circle of radius 14cm and a semi circle is drawn with BC as diameter. Find the area of shaded region.​

Answer»

ong>Step-by-step explanation:

in right angle TRIANGLE ABC

by using PYTHAGORAS therum ,

=>AC^2+AB^2 =BC ^2

=>14^2+14^2=BC^2

=>196+196=BC^2

=>BC=√392

=>BC=14√2

diameter of the semi circle =14√2

=>2r=14√2

=>r=14√2=7√2 cm

area of the SEGMENT BPOC= area of quadrant - area of triangle =πr^2/4-1/2* base *HEIGHT

=1/4*22/7*14*14-1/2*14*14

area of shaded region =area of semi circle -area of segment
