Z^5=-7776iFind the solution of the following equation whose argument is strictly between 270 and 360 degrees

Answers

Answer:

Z=+6

Step-by-step explanation:

Z^5=-7776i

Let's note that i I mathematics means negative one i.e

i = -1

So the equation is equal to

Z^5=-*-(7776)

Z^5 = 7776

Z= 5√7776

Since it's a divisible by 6

It's giving us a clue that 6 it's the answer.

Ok let's check the 5th root of 7776 in our calculator.

Z=+6

+6 is the solution to the equation

Z^5=-7776i

What would be the cost for 5 of the cost for 5 of the gift cards a $80
b $90
c$100
d$110

Answers

Answer:

Cost for the 5 gift cards = $20

Step-by-step explanation:

In the given graph,

y axis shows the "total cost" in dollars

x axis shows the "number of gift cards"

According to the graph:

Cost of 1 card = $20

Cost of 2 cards = $40

Cost of 3 cards = $60

Cost of 4 cards = $80

We see that that relation represents the linear relation.

So, cost of 5 cards = 5*$20 = $100

That's the final answer.

I hope it will helps you.

the table shows that 1 gift card equals 20 dollars... so 20 * 5 = 100
so your answer is C.) $100
