Assuming that A is on the top left, B is on the top right, and C is on the bottom left,
A = (2, 9)
B= (11, 9)
C = (2, 2)

What are the coefficients in the polynomial 5x^2 + 2x - 4?A: 5, 2
B: -5, -2
C: 5, 2, -4
D: 5, -2, -4

Answers

The solution is, A) 5, 2 are the coefficients in the polynomial 5x^2 + 2x - 4.

What are Polynomials?

Polynomials are sums of k-xⁿ terms, where k can be any number and n can be any positive integer.

here, we have,

given that,

the polynomial is : 5x^2 + 2x - 4

now, we have to find the coefficients in the polynomial 5x^2 + 2x - 4

we know that,

a coefficient is a multiplicative factor in some term of a polynomial, a series, or an expression; it is usually a number, but may be any expression. When the coefficients are themselves variables, they may also be called parameters.

and. we have,

a variable is a symbol that represents a mathematical object. A variable may represent a number, a vector, a matrix, a function, the argument of a function, a set, or an element of a set.

so, we get,

a coefficient is the number in front of the variable,

here, 5, 2 are the coefficients.

and the variable is x.

Hence, The solution is, A) 5, 2 are the coefficients in the polynomial 5x^2 + 2x - 4.

A) 5, 2
Because a coefficient is the number in front of the variable, and the variable is x.

If dy/dx=1/x, then the average rate of change of y with respect to x on the closed interval [1, 4] is a) -1/4
b) (1/2)*ln(2)
c) (2/3)*ln(2)
d) 2/5
e) 2

Answers

The first thing to do here is to integrate the ordinary differential equation dy/dx = 1/x. This is equal to y = ln x + C. Assuming C is zero. y = lnx. substituting the two interval,
y1 = 0 y2 = ln 4
the rate of change then is equal to (ln4 - 0) / (4-1) equal to 2/3 ln 2. Answer is C
