A capsule is in the shape of a cylinder with two hemisphere stuck to each of its ends. If the length of the entire capsule is 12 mm and the diameter of the capsule is 5 mm, how much medicine it can hold?

Answer»

ANSWER:

the question has been solved step by step below

Step-by-step explanation:

Width of capsule =5mm

radius of HEMISPHERE =2.5mm

c.s.a of hemisphere=2πr SQUARE

=275mm square × 2

=550mm square

height of CYLINDER=14-radis of 2 hemisphere

=9mm

c.s.a of cylinder =2πrh

=131.2mm square

surface area of capsule =c.s.a of 2 hemisphere

+ c.s.a of cylinder

= 682.2mm square

[PIE value=22/7]

the surface area of tablet is 682.2mm square

The roots of a quadratic eq x square minus 4root2x plus 6​

Answer»

ANSWER:

GIVEN QUADRATIC equation:

x²-4√2x+6=0

=> x²-4√2x = -6

=> x²-2*x*2√2 = -6

=> x²-2*x*2√2+(2√2)²=-6+(2√2)²

=> (x-2√2)² = -6 + 8

=> (x-2√2)² = 2

=> x-2√2 = ±2

=> x = 2√2 ± 2

=> x = 2(√2±1)

THEREFORE,

x = 2(√2+1) or x = 2(√2-1)

Find the value of k if X -1 is a factor of 4x³0+3x²-4x+k​

Answer»

Question :–

FIND the value of K if X -1 is a factor of 4x³0 + 3x²- 4X + k.

To Find :–

  • Value of k.

Solution :–

• x - 1 = 0

• x = 1

Put the value of x in the given equation.

→ 4x³0 + 3x² - 4x + k = 0

→ 4 (1)³0 + 3(1)² - 4 (1) + k = 0

→ 0 + 3 - 4 + k = 0

→ 3 - 4 + k = 0

→ -1 + k = 0

→ k = 1
