when they cross u should get a perfect solution of (2,6)
Answer:
Step-by-step explanation:
Given the following complex numbers, we are to expressed them in the form of a+bi where a is the real part and b is the imaginary part of the complex number.
1) (2-6i)+(4+2i)
open the parenthesis
= 2-6i+4+2i
collect like terms
= 2+4-6i+2i
= 6-4i
2) (6+5i)(9-2i)
= 6(9)-6(2i)+9(5i)-5i(2i)
= 54-12i+45i-10i²
= 54+33i-10i²
In complex number i² = -1
= 54+33i-10(-1)
= 54+33i+10
= 54+10+33i
= 64+33i
3) For the complex number 2/(3-9i), we will rationalize by multiplying by the conjugate of the denominator i.e 3+9i
= 2/3-9i*3+9i/3+9i
=2(3+9i)/(3-9i)(3+9i)
= 6+18i/9-27i+27i-81i²
= 6+18i/9-81(-1)
= 6+18i/9+81
= 6+18i/90
= 6/90 + 18i/90
= 1/15+1/5 i
4) For (3 − 5i)(7 − 2i)
open the parenthesis
= 3(7)-3(2i)-7(5i)-5i(-2i)
= 21-6i-35i+10i²
= 21-6i-35i+10(-1)
= 21-41i-10
= 11-41i
Answer:
30
Step-by-step explanation:
x= -2 and y= 3
Hence, simply put it in the equation:
3x + 4y^2
3(-2) + 4(3)^2
-6 + 4(9)
-6 + 36
30

Property tax is an ad valorem tax assessed on real estate by a local government and paid by the property owner. Income tax is tax levied by a government directly on income, especially an annual tax on personal income. Both pay the government but one is for their land and the other is for money they make.
Answer:
It's 40
Step-by-step explanation:
Arithmetic Sequence.
Common Difference:
160−163=−3
157−160=−3
d=−3
Explicit Formula:
an=a1+(n−1)d
a42=163+(41)(−3)
a42 = 40
