Question

do only second number ​

Answer 1

Answer:

1. 1 be the answer of this ques

Step-by-step explanation:

When any boat displaces a weight of water equal to its own weight, it floats. This is often called the "principle of flotation": A floating object displaces a weight of fluid equal to its own weight

Answer 2

Answer:

Let p(x) = x3 – 4x2 + 5x – 2

Then, p(2) = (2)3 – 4(2)2 + 5(2) – 2

= 8 – 16 + 10 – 2 = 0

p(1) = (1)3 – 4(1)2 + 5(1) – 2 = 1 – 4 + 5 – 2 = 0

Hence, 2, 1 and 1 are the zeroes of the given polynomial

x3 – 4x2 + 5x – 2.

Now, Let α = 2 , β = 1 and γ = 1

Then, α + β + γ = 2 + 1 + 1 = 4

αβ + βγ + γα = (2)(1) + (1)(1) + (1)(2) = 2 + 1 + 2 = 5 and

αβγ = 2 × 1 × 1 = 2

Thus, the relationship between the zeroes and the coefficients is verified
