This is really a long way to go to make something complicated
out of something simple.  The last choice does the job.

cos(180)  =  -1
sin(180)  =   0

So       4 [cos(180) + i sin(180) ]

       =   4 [ -1      +  i (0) ]

       =     -4     yay!

Sorry i forgot how to do this....please help meeeee ;-;
Mariulka [41]

Answer:

98

Step-by-step explanation:

ABSOLUTE BRACKETS MEAN ABSOLUTE VALUE- this means that negatives will come out as positives since their absolute values are the same. So |-9| is just 9.

|-81-17| (apply the rule I just gave you)

|81+17|

PLEASE ANSWER ILLG IVE YOU BRAINLIEST
Yuri [45]

Answer:

#1. 31.4 square units

Step-by-step explanation:

We are solving for the square units and also we are circumference formular

which is C = R x 2) (3.14)

R is 5 but in a case they don't give us the Radius and gives us the Diameter we decide the Diameter by 2 and we will get the radius.

Back to the problem

C = R x 2) (3.14)

C =  5 x 2 x 3.14

C = 10 x 3.14

C = 31.4

Can someone help me with this in a scientific notation
Leviafan [203]

Answer:

3.762 x 10^-7

Step-by-step explanation:

Alright this has the same exact concept as other scientific notation problems.

First, multiply your first numbers: 4.18 x 9 = 37.62

Next, we add our powers together -4 +-4 = -8 (can also be read as -4 - 4 = -8)

We now have 37.62 x 10^-8

Wait! This isn't in scientific notation.

Taking a closer look at this we see 37.62 x 10^-8 can be adjusted by moving the decimal over to the left. Scientific notation must be in simplest form with only one number on the left of the decimal. This gives up 3.762.

Now we need to adjust our notation. Since we moved the decimal over one we are adding one more power to our problem.

Our current power of -8 is now adding a power due to moving the decimal place over one unit to the left. This is equivalent to saying -8 + 1 which equals -7. Now that we fixed our powers, we can put our equation back together for our final answer

3.762 x 10^-7

If total sales in the ice cream category were $4.4 billion and Breyer’s sales were $650,417,792, what would be its market share?
Tresset [83]

Answer:

14.8%

Step-by-step explanation:

The formula for market share = Total sales of the company at a particular period/ Total sales of the market × 100%

Total sales of the company = Breyer's sales = $650,417,792

Total sales of the market = Total sales in the ice cream category market = $4.4 billion

= $650,417,792/ $4,400,000,000, × 100

= 14.782222545%

Therefore, approximately to the nearest tenth, Breyer's market share is 14.8 %
