8 0

Answer:

308[cos(45) + isin(45)]

Step-by-step explanation:

z1×z2:

Modulus: r1 × r2

= 7×44 = 308

Argument: theta1 + theta2

= -70 + 115 = 45

z1z2 = 308[cos(45) + isin(45)]

Or

z1z2 = 154sqrt(2) + (i)154sqrt(2)

sqrt: square root

a < (a + b)/2 < b

Solve the first inequality.

a < (a + b)/2

2a < a + b

a < b

Solve the second inequality.

(a + b)/2 < b

a + b < 2b

a < b

Both inequalities are true.  Therefore, a < (a + b)/2 < b.

Sal made 8 ft of sausage links on Friday morning. He used 4 ft for dinner service on Friday night. On Saturday morning, he made
oee [108]

Answer:

Net change in the amount of sausage Sal had from Friday morning until after dinner service Saturday night = 8 - 0 = 8 ft

Step-by-step explanation:

Amount of  sausage links made on Friday morning = 8 ft

Amount of  sausage links used on Friday night = 4 ft

Amount of  sausage links remaining = 8 - 4 = 4ft           (i)

Amount of  sausage links made on Saturday morning = 8 ft         (ii)

So,

Total amount of  sausage links = 8 + 4 = 12 ft   (from (i) and (ii) )

Amount of  sausage links used on Saturday night = 12 ft

Amount of sausage links remaining = 12 - 12 = 0 ft

Net change in the amount of sausage Sal had from Friday morning until after dinner service Saturday night = 8 - 0 = 8 ft
