Step-by-step explanation:

Sin(A+B) = Sin A Cos B + Cos A Sin B.

Sin 75 = Sin ( 45 + 30) = Sin 45 Cos 30 + Cos 45 Sin 30. Sin 75 = (1 / √2) ( √3 / 2) + (1 / √2) ( 1 / 2) = [ √3 + 1] / 2√2.

Write an equation describing the relationship of the given variables.
uranmaximum [27]

Answer:

y = 2x^4

Step-by-step explanation:

The given statement can be represented as:

y\ \alpha\ x^4

x =3; y = 162

Given

Represent this as an equation

y\ \alpha\ x^4

Convert variation to equation

y = kx^4

Where k is a constant of variation.

Substitute x =3; y = 162

162 = k * 3^4

162 = k * 81

Solve for k

k = 162/81

k =2

To get the equation, we have:

y = kx^4

Substitute 2 for k

y = 2x^4

Which the is the correct answer?
agasfer [191]

To solve this problem, we need to use combination which is statistical tool to determine the number of ways an event may occur. The combination to select a 5 a side team from 12 students is 792.

<h3>Combination</h3>

This a mathematical technique that is used to determine the number of possible arrangements in a collection of items where the way they're arranged does not matter.

Data;

  • Number of Students = 12
  • Team = 5

The combination for this would be

C = ^1^2C_5 = 792

The combination to select a 5 a side team from 12 students is 792.
