The answer is c folk
6x4 + 7x2 – 3 = 0
5x6 + x4 + 12 = 0
x9 + x3 – 10 = 0
Answer:
Option A is correct
Step-by-step explanation:
We have been given four equations and we need to tell which one of them is quadratic
Case1:
In this we will use the formula
Here, a=x and b=2
The equation will become
Hence, after simplification equation will become
which is a quadratic equation because quadratic equation is the equation is the equation which has degree 2.
In this equation degree is 2 hence, quadratic
Case2:
is not quadratic since, degree in this equation is 4 not 2
Hence, biquadratic not quadratic
Case3:
is not a quadratic equation since, degree in this equation is 6.
Hence, not quadratic
Case4:
is not quadratic since, degree in this equation is 9
Hence, not quadratic
Therefore, Option A is correct

Hi there! :)
Answer:
Use the formula V = 1/3(bh) to solve for the volume of the cone where b = πr² where π ≈ 3.14:
Find the area of the base:
b = π(7)²
b = 49π
b = 153.86 mm²
Find the volume:
V = 1/3(153.86 · 7)
V = 1/3(1077.02)
V = 359.006 ≈ 359.01 mm³.
