Determine if v is in the set spanned by the columns of B. B= [8 -3 2
9 4 -7
6 -2 4
5 -1 10]
V= [23
-24
18
17]
Choose the correct answer below and, if necessary, fill in the answer box(es) to complete your choice.
A. Vector v is not in the set spanned by the columns of B, because the columns of B, b1, b2, and b3 are linearly independent.
B. Vector v is not in the set spanned by the columns of B because the reduced echelon form of the matrix formed by writing B with a fourth column equal to v is .
C. Vector v is in the set spanned by the columns of B because b1 + b2 + b3 = v.
D. Vector v is in the set spanned by the columns of B because the columns of B span R4.

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
