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:
Initial amount P = $12000
Interest after 2 years I = 4%*2 = 8%
<u>Investment into Trust fund:</u>
- $12000 + $5000 + 0.08*$12000 = $17960
<u>Interest amount to exceed $20000:</u>
<u>Time required to get $2040:</u>
- 17960*0.045x = 2040
- 808.2x = 2040
- x = 2040/808.2
- x = 2.52 years
The investment will exceed $20000 in the second half of the third year
Answer:
x = -5
Step-by-step explanation:
x+7=2
-7 | -7 -7 from both sides
x= -5
X equals 4. (this is supposed to be 20 characters long so i’m just typing randomly)
Answer:
There are 9 lemon bars left from the batch.
Step-by-step explanation:
One batch = 15 lemon bars
Josh: ate 2 lemon bars
13 lemon bars remaining.
Claire: ate twice as many as Josh
Meaning: 2 × 2 = 4
9 lemon bars remaining.
There are 9 lemon bars left from the batch.
