Question 5: consider a linear system whose augnented matrix is of the form 1 1 3 21 1 2 4 3 1 3 a b (a) for what values of a and b will the system have infinitely many solutions? (b) for what values of a and b will the system be inconsistent?

answer: 800

step-by-step explanation:

let's fu(!

step-by-step explanation:

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92

30.5*10=350$

you have to multiply the number without the decimal point then add it later but if its tenn u must move the place value of the decimal point 1 to the right.
