Answer:
13 + 7i
Step-by-step explanation:
We have given complex number
The difference of given complex number is:
(6 + 3i) - ( -7- 4i) = {6 - (- 7)} + {3 -( - 4)}i
⇒ 13 + 7i
Since the difference of two complex number (a + ib) and (c + id) is:
(a - c) + i(b - d)
I do believe it is B or D, hmm Id say D TBH
Answer:
Step-by-step explanation:
Yes, F(x)=7-2x is a polynomial function for which the sole x term has the exponent 1 and the constant term has the exponent 0:
F(x) = -2x^1 + 7x^0
As is true of all polynomial functions, the exponents are all positive integers (plus that of the constant term is zero).
Answer:
Surface area is the sum of all of the areas of the faces in a solid figure. To find the surface area, we must be able to calculate the area of each face and then add these areas together. A net is a two-dimensional diagram of a three-dimensional figure. With a net, we can see each face of the pyramid more clearly. To find the surface area, we need to calculate the area for each face in the net, the sides and the base. The side faces of a pyramid are always triangles, so we use the area formula for triangles to calculate their area: A=1/2 bh (BASE TIMES HEIGHT)..

Answer:
= 5.196 i
Step-by-step explanation:
The problem tells us to find the square root of -98 +71
√(-98 + 71)
= √(-27)
Which is an imaginary number
=√(-3^3)
Lets remember that, √(-1) = i
= i*3√(3)
= 5.196 i
