Find the mass of the pole, given that the mass of 1 cm3 of iron is 8 gm. Calculate the total surface area and the volume of the rocket. If the hypotenuse is 13 cm, form the quadratic equation to find the base of the triangle. Form the quadratic equation to find how many marbles they had to start with, if John had x marbles.

Find the value of water i displaced out of the cylinder. Even if you are not clear with your concepts, follow any one solution provided. Solution 4 : Answer : Since - 2 is one zero of. A cylindrical road roller made of iron is 1 m long. A toy is in the form of a cone of radius 3. We know that, in equilateral triangle the angle between two adjacent side is 60 and all three sides are equal. Now, Remainder Hence, the value of k is.

For Example: is a polynomial in the variable x of degree 2. Therefore Hence, the family of quadratic polynomials is, where k is any non-zero real number Solution 10 : Answer : We have to find the value of k. Therefore, the quadratic polynomial is. A solid is in the shape of a cone surmounted on a hemi-sphere, the radius of each of them is being 3. A conical hole is drilled in a circular cylinder of height 12 cm and base radius 5 cm. Clearly, Right hand side of the above result is divisible by the divisor. Dividing by Therefore, quotient and remainder.

The diameter of the hemisphere is 14 cm and the total height of the vessel is 13 cm. If 0, -3 and 0, 3 are the two vertices of an equilateral triangle, find the coordinates of its third vertex. The radius of the cylindrical base is 20 m. Find the volume of water left in the cylinder, if the radius of the cylinder is 60 cm and its height is 180 cm. If the internal diameter of dome is equal to its total height above the floor, find the height of the building? The largest cone is curved out from one face of solid cube of side 21 cm. Hence, quadratic polynomial is a square of linear polynomial then its two zeros are coincident. Therefore, is a factor of.

Prove that the points 3, 0 , 4, 5 , -1, 4 and -2, -1 taken in order, form a rhombus. By using division algorithm we have Hence, the zeros of the given polynomials are. The height of cone is 4 cm and the diameter of the base is 8 cm. Now, we divide by to find the zero of. Solution: Let the ordinate of other end by y, then The distance between 2, -3 and 10, y is Question 6. Then, And Let S and R denote respectively the sum and product of the zeros of a polynomial Whose zeros are and.

Solution 35 : Answer : We know that if is zero polynomial then is a factor of Since is a factor of. Name the quadrilateral formed, if any, by the following points, and give reasons for your answers : i A -1, -2 , B 1, 0 , C -1, 2 , D -3, 0 ii A -3, 5 , B 3, 1 , C 0, 3 , D -1, -4 iii A 4, 5 , B 7, 6 , C 4, 3 , D 1, 2 Solution: Question 39. Sharma Class 10 Solutions R. A cylindrical vessel with internal diameter 10 cm and height 10. The diameter of cylinder is 24 m. A solid wooden toy is in the form of a hemisphere surmounted by a Cone of same radius.

Then, From From From Hence, it is verified that the numbers given along side of the cubic polynomials are their zeros and also verified the relationship between the zeros and coefficients. Hence, the value of is. A circus tent has cylindrical shape surmounted by a conical roof. Find the distance between the following pair of points : i -6, 7 and -1, -5 ii a + b, b + c and a — b, c — b iii a sin α, -b cos α and -a cos α, -b sin α iv a, 0 and 0, b Solution: Question 2. If the whole length of the solid is 104 cm and the radius of each of the hemispherical ends is 7 cm, find the cost of polishing its surface at the rate of Rs. Polynomial is an expression which consists of coefficients and variables which are also called indeterminate that involves only the operations of multiplication, addition, subtraction and non-negative integer exponents of variables. A rocket is in the form of a circular cylinder closed at the lower end with a cone of the same radius attached to the top.

If a point A 0, 2 is equidistant from the points B 3, p and C p, 5 , then find the value of p. Find the equation of the perpendicular bisector of the line segment joining points 7, 1 and 3, 5. Therefore, Since the parabola cuts x-axis at two points, this means that the polynomial will have two real solutions Hence Hence and Solution 15 : Answer : The graph of the polynomial or the curve touches x - axis at point.
