Find the standard matrix for the following transformation t : r4 → r3: t(x1,x2,x3,x4) = (x1 −x2 +x3 −3x4,x1 −x2 +2x3 +4x4,2x1 −2x2 +
x3 +5x4)
(a) compute t(e⃗ ), t(e⃗ ), t(e⃗ ), and t(e⃗ ).
1234
(b) find an equation in vector form for the set of vectors ⃗x ∈ r4 such
that t (⃗x) = (−1, −4, 1). (c) what is the range of t?

step-by-step explanation:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
