WILL GIVE BRAINLIEST AND 20 POINTS! What is the correct formula for the value of the determinant? A. ab - cd B. ab + cd C. ad - cb D. ad + cb

Option C

Step-by-step explanation:

In the matrix, the determinant is the difference between the opposite elements multiplied.

So, the opposite elements multiplied will give us:

=> ad,bc

The difference is

=> ad-bc

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
