Answer: The answer would be choice C because there is a constant rate of change of 3 :)
Step-by-step explanation:
Answer:
b = 1530
Step-by-step explanation:
1/17 b = 90
(17)1/17b = 90 × 17
b = 1530
Given that a polynomial function P(x) has rational coefficients.
Two roots are already given which are i and 7+8i,
Now we have to find two additional roots of P(x)=0
Given roots i and 7+8i are complex roots and we know that complex roots always occur in conjugate pairs so that means conjugate of given roots will also be the roots.
conjugate of a+bi is given by a-bi
So using that logic, conjugate of i is i
also conjugate of 7+8i is 7-8i
Hence final answer for the remaining roots are (-i) and (7-8i).
Answer:
18 boys
Step-by-step explanation:
we add 2 and 3 because they are equal parts:
2+3=5
Then we divide 45 by 5 because we want to find what 1 part equals"
45/5=9
We now do 9*2 to get an answer of:
9*2=18
hope this makes sense!
Answer:
-1+√6
-1-√6
Step-by-step explanation:
x²+2x-5=0
x=(-2±√(2²-4(-5)))/2=(-2±√(4+20))/2=(-2±√24)/2
x₁=(-2+√24)/2 or x₂=(-2-√24)/2
x₁=(-2+2√6)/2 or (-2-2√6)/2
x₁=-1+√6 or x₂=-1-√6
