For z = –3 – 5i, which graph shows z and the product of z · i?
earnstyle [38]

Answer:

A

Step-by-step explanation:

z = -3 - 5i

z (i) = i (-3 - 5 i)

z (i) = -3i - 5i^2

z (i) = -3i - 5 (-1)

z (i) = -3i + 5

z (i) = 5 - 3i

Therefore, letter A is the correct answer.

katrin [286]
<h3>Answer:  75.36 square feet</h3>

Your teacher may want you to type the number only.

==========================================================

Work Shown:

SA = surface area of a cylinder

SA = 2*pi*r^2 + 2*pi*r*h

SA = 2*3.14*2^2 + 2*3.14*2*4

SA = 75.36

The surface area is roughly 75.36 square feet.

Which formula represents this sequence 2,8,14...?
Vikentia [17]

Answer:

a_{n} = 6n - 4

Step-by-step explanation:

There is a common difference between consecutive terms in the sequence, that is

8 - 2 = 14 - 8 = 6

This indicates the sequence is arithmetic with n th term

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 2 and d = 6 , thus

a_{n} = 2 + 6(n - 1) = 2 + 6n - 6 = 6n - 4

Thus the formula representing the sequence is

a_{n} = 6n - 4
