PLATO: Type the correct answer in each box. The vector is first dilated by a factor of 2.5 and then rotated by pi/2 radians. If the resulting vector is [a / b], then a = __ and b = __

a = -1, b = -2.5

Step-by-step explanation:

Rule for the dilation of a vector by a scale factor of k is,

(x, y) → (kx, ky)

BY using this rule for a vector by a scale factor of 2.5

→

Followed by the rotation by 90° Or radians,

Rule for rotation of a vector by 90° is,

(x, y) → (-y, x)

By this rule vector will become,

→

If we represent this vector by ,

Then a = -1 and b = -2.5 will be the answer.

this was already solved by me with a different person. if you look it up in the search bar at the top of the page, you will get the answer.

step-by-step explanation:

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.
