Answer:

 (b)

Step-by-step explanation:

A suitable calculator or spreadsheet can find the matrix product for you. Here, the answer choices differ in their upper left term, so we can determine the correct choice by finding the value of that term. It is the dot product of the first row of B and the first column of A.

  (5)(3) +(7)(3) +(3)(2) = 15 +21 +6 = 42

This matches choice B.

PLZ ans have mocks plz
Yanka [14]

Answer:

The table will be:

x |-2 | -1 | 0 | 1 | 2  

y | 1  | 4 | 5 | 4 | 2

Step-by-step explanation:

The function is:

y=5-x^{2}

a) The x values of the table is:

x |-2 | -1 | 0 | 1 | 2

So, when x = -2, y will be:

y(-2)=5-(-2)^{2}=5-4=1

Doing the same with the other x values we have:

y(-1)=5-(-1)^{2}=5-1=4

y(0)=5-(0)^{2}=5

y(1)=5-(1)^{2}=5-1=4

y(2)=5-(2)^{2}=5-4=1

The table will be:

x |-2 | -1 | 0 | 1 | 2  

y | 1  | 4 | 5 | 4 | 1

I hope it helps you!
