Answer:
the question is incomplete, below is the complete question
"ress the following complex numbers in rectangular form. Show how you get the answer and use a calculator to verify your answer. E.g. 2 pts for 2∠30°=2(cos30°+jsin30°)=1.73+j, 1 pt for 2∠30°=1.73+j. Same grading criteria as 1.4. (a) Z1=5eⁱ³⁰ (b) z2=−3 ∠(−45°) (c) z3=2∠(−90°)
answer
a.Z1=4.33+j2.5
b. Z2=-2.12+j2.12
c.Z3=-2j
Step-by-step explanation
note that
Z=reⁱⁿ=r(cosπ+jsinπ)
hence from Z1=5eⁱ³⁰ wen have
Z1=5(cos30+jsin30)
Z1=5(0.8660+j0.5)
Z1=4.33+j2.5
b.also from z=r∠(π)=r(cosπ+jsinπ)
Hence,
z2=−3 ∠(−45°)=-3(cos(-45)+jsin(-45))
Z2=-3(0.7071-j0.7071)
Z2=-2.12+j2.12
c. z3=2∠(−90°)=2(cos(-90)+jsin(-90))
Z3=2(0-j)
Z3=-2j
The y is greater than the function
1 conclusion you can make is that p is the bisector of the line. And another is that QP and PR are congruent.
Sorry if not right :/
Answer:
The time required to finish the work by both candy and Tim working together = 36.83 minute
Step-by-step explanation:
Time taken by the candy to finish the work 
= 85 min
Time taken by the Tim to finish the work 
= 65 min
Thus the time taken by both to finish the work = 
Put the values of and we get ,
= 
= 
= 36.83 minute
Thus the time required to finish the work by both candy and Tim working together = 36.83 minute
Step-by-step explanation:
f(x)=x^2+x
so
f(x-1) = (x - 1) ^ 2 + (x - 1)
= x^2 - 2x + 1 + x - 1
= x^2 - 3x
and
f(x+1) = (x + 1) ^ 2 + (x + 1)
= x^2 + 2x + 1 + x + 1
= x^2 + 3x + 2
now
f(x-1) + f(x+1) = 6
x^2 - 3x + x^2 + 3x + 2 = 6
2x^2 = 4
X = √2
brainliest pls took long enough to solve
