Гс 1 find all values of c (if aly) for which a has no inverse, if a 1 c a. a b. a has no inverse only when c = 0 1 exists for all real values of c c. a has no inverse only when c =1 c -1 or d. a has no inverse whenever c = 0 or c= ±l is not invertible for all real values of c . (1e. 41 does not exist for any value of c) e. a reset selection

the answer is a i belaeve atleast thats what my calculator just gfave me

step-by-step explanation:

b.-4 units

all you   do is count how many times you move

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
