Sharon presently earns $262 per wk. She is offered another job which pays $16,200 per year. Which has the better pay?

ANEK [815]

Earnings For The First Job
monthly pay =262 × 4
= 1048
Yearly pay = 1048 × 12
= 12 576

Earnings for the second job
yearly pay = 16 200

Difference for the two jobs

16200 - 12576 = 3624

Answer = The second job that pays $16200 has a better from the first job by 3624

Let:T : ℝ3→ℝ3 be the transformation that projects each vector x=(x1,x2,x3)onto the plane

dangina [55]

Answer:

Step-by-step explanation:

A linear transformation must satisfy the following properties.

- T(0) = 0.

- For vector a,b then T(a+b) = T(a) + T(b).

- For a vector a and a scalar r, it must happen that T(ra) = rT(a)

In this case we have that T(a,b,c) = (a,0,c).

Note that T(0) = T(0,0,0) = (0,0,0) = 0. So, the first property holds.
