If complex coefficients are allowed, the answer is 3.
If the polynomial must have real coefficients, then each complex root comes as a pair of complex conjugate roots.
Root -5 is real, so that is 1 root, and degree 1.
Root 1 + 4i is complex, so it must come with its complex conjugate, 1 - 4i. This adds 2 roots to the polynomial, and now we're up to degree 3.
Root -4i is also complex. It also must come with its complex conjugate, 4i. That adds two more roots, and the degree is 5.
Answer: The least possible degree is 5 with real coefficients.
Answer:
Jason will have earned $35 in simple interest.
Step-by-step explanation:
Simple interest = Principal *rate *time
S.I = P * r * t
Principal = the amount deposited = $280
rate = 2.5%
time = 5 years
S.I = 280 *2.5% *5
S.I = 7*5
S.I = $35
Therefore, in 5 years, Jason will have earned $35 in simple interest.
Answer:
true
Step-by-step explanation:
if we say x is less than 7 and x is equal to 6 it makes sense that 6 is less than 7
