Suppose T: ℝ3→ℝ2 is a linear transformation. Let U and V be the vectors given below, and suppose that T(U) and T(V) are as given
ira [324]

Answer:

T(3u+2v)=(-10,29)

Step-by-step explanation:

T is a linear transformation, hence it is homogeneous (T(cr)=cT(r) for all real c and r∈ℝ³) and additive (T(r+s)=T(r)+T(s), for all r,s∈ℝ³). Apply these properties with r=3u and s=2v to obtain:

T(3u+2v)=T(3u)+T(2v)=3T(u)+2T(v)=3(-2,5)+2(-2,7)=(-6,15)+(-4,14)=(-10,29)

We don't have an explicit definition of T, so it's more difficult to compute T(3u+2v) directly without using these properties.

A salesperson is paid $140 per week plus 10% commission on her weekly sales of x dollars. Find a linear function that represents
Verizon [17]

Her weekly sales is X dollars

10% as a decimal is 0.10

Total commission is 0.10X ( 10% times weekly sales)

You then need to add that to her base pay of $140.

The equation is: w = 0.10x + 140
