1) cos (150°)=- cos(180°-150°) = - cos(30°) and  - cos30° =  - √(3) / 2
sin(150°) = sin(180°-150°) =sin30. and sin30° = 1/2

Then : 5/2(cos 150° + i sin 150°) becomes : 5/2{(-√(3) /2 + I (1/2)]

OR 5/4( - √3 + i)

Rina8888 [55]

Answer:

(3 * 100,000) + (0 * 10,000) + (4 * 1000) + (0 * 100) + (5 * 10) + (6 * 1)

Step-by-step explanation:

We want to represent the value of this number using expanded notation

Mathematically, that will be;

(3 * 100,000) + (0 * 10,000) + (4 * 1000) + (0 * 100) + (5 * 10) + (6 * 1)

= 300,000 + 0 + 4000 + 0 + 50 + 6

= 304,057

Nicole deposited $2,000 at 6% simple interest. How long will it be before she has $2,600 in her account?
Mashcka [7]
5 years, you have to make 6% a decimal so it would be 0.06. You would then multiply 2000 and 0.06 and get 120. You keep adding 120 to 2,000 until you reach 2,600. Hope this helped!

What is the sum of the first 150 odd positive integers?<br> Show work please!!!
LenaWriter [7]

Answer:

11325.

Step-by-step explanation:

Step 1: address the formula, input parameters & values.

Input parameters & values:

The number series 1, 2, 3, 4, . . . . , 149, 150.

The first term a = 1

The common difference d = 1

Total number of terms n = 150

Step 2: apply the input parameter values in the formula

Sum = n/2 x (a + Tn)

= 150/2 x (1 + 150)

= 22650/2

1 + 2 + 3 + 4 + . . . . + 149 + 150 = 11325

Therefore, 11325 is the sum of positive integers up to 150.
