HELP PLS I FORGOT LOL TYSM!

Answer:

A. The coefficients of the sum are whole numbers and the sum is a polynomial.

Step-by-step explanation:

The approach to demonstrate the closure property for the sum consists in defining what a polynomial is and demonstrate that the sum of two polynomials with integer coefficients is equal to a polynomial with integer coefficients. We proceed to show the proof below:

1) 5\cdot m -3, 2\cdot m + 4 Given

2) (5\cdot m -3)+(2\cdot m +4) Definition of addition

3) (5\cdot m +2\cdot m ) +[(-3)+4] Definition of substraction/Associative and Commutative properties

4) (5+2)\cdot m +1 Distributive property/Definition of substraction

5) 7\cdot m +1 Definition of addition/Result

Hence, the coefficients of the sum are whole numbers and the sum is a polynomial. The correct answer is A.

Do I have this one correct
nikklg [1K]

Answer:

Option B is correct

Step-by-step explanation:

Given is a cos funciton.

Period = 3

Max = 20 and minimum =0

Hence centre line is y = 1/2 (max+min)

i.e. y =10 is the central line

Let the funciton be of the form

y = a cos (bx+C)+d

We got d = 10...i

Period =3

Hence b = \frac{2\pi}{3} ... ii

Amplitude = a = distance of max from central line = 20-10 =10...iii

Since reflection over x axis, sign of a =negative

a=-10

Since no horizontal shift, c=0 ... iv

Put to gether the function is

y=-10cos\frac{2\pi x}{3} +10
