(a) let v = r 2 be the vector space of 2-dimensional real row vectors. decide which of the following subsets of v are vector subspaces of v and which aren’t. justify your answers. (i) l1 = {(x, y)|y = 3x}. (ii) l2 = {(x, y)|y = 3x + 1}. (iii) p = {(x, y)|y = x 2}. (b) let w = m at2×2(r) be the vector space of 2 × 2 real matrices. decide which of the following subsets of w are vector subspaces of w and which

i have no clue at all sorry

step-by-step explanation:

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
