Answer:
<u>It</u><u> </u><u>has</u><u> </u><u>two</u><u> </u><u>roots</u>
that is †2.4i and -2.4i
Step-by-step explanation:
for a root, f(x) is zero
subtract 6 from both sides:
remember: from complex numbers, i² is -1
take square root on both sides:
4+2=6 then you bring the 6 to the other side so you have combine like terms. 6-6=0 so its 0
Answer:
Camels has to pay $42 more as interest
Step-by-step explanation:
We are given that Carmela borrows $400 and will pay 5.25% yearly simple interest.
Principal = $400
Rate of interest = 5.25%
Time = 2 years
Formula :
So,
SI=42
She borrows the money for 4 years instead of 2 years,
So,
SI=84
Difference in interests = 84-42 = 42
Hence Camels has to pay $42 more as interest
To do this we need to see how many degrees it dropped then divide by time (15 hr.).
52 - (-23)
75
75/15
5 deg/hr
Hope this helped!
