f+4(f-2)
To find f(-2), substitute -2 into the function f(x). So, f(-2) = 2(-2)^3 - 2(-2)^2 + 50. Simplifying this expression gives f(-2) = 2(-8) - 2(4) + 50 = -16 - 8 + 50 = 26.
Use the remainder theorem:- f(x) = x3+nx2+3x-5 f(x) becomes f(2) because the divisor is x-2 and 2-2 = 0 f(2) = 8+4n+6-5 = -3 f(2) = 4n+9 = -3 f(2) = 4n = -12 f(2) = n = -3 So the value of n in the expression is -3 Check: f(2) = 8+(4*-3)+6-5 = -3
It is not possible to find the expression of 2y if f(x) = 2x - 3x.

The solubility product expression for CaF2(s) is written as Ksp = [Ca2+][F-]^2, where brackets denote the concentration of each ion at equilibrium.

f+4(f-2)
It is 5*f where f is an expression.
Because f represents a function.
To find f(-2), substitute -2 into the function f(x). So, f(-2) = 2(-2)^3 - 2(-2)^2 + 50. Simplifying this expression gives f(-2) = 2(-8) - 2(4) + 50 = -16 - 8 + 50 = 26.

Coulomb's law states that the electrostatic force between two point charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. The expression for Coulomb's law is F = k * (|q1 * q2|) / r^2, where F is the force, k is the electrostatic constant, q1 and q2 are the magnitudes of the charges, and r is the distance between the charges.
It is an expression and can be simplified to: 3d+f+1
The equation can be rewritten as F = ma, where F represents force, m represents mass, and a represents acceleration.
