A famous recipe for New Orleans jambalaya calls for 1 1/4 cups of Gulf shrimp. The recipe serves 5 people. Trinetta and Agnes wa
Paha777 [63]

Answer: C. 3 cups

Step-by-step explanation:

Given: In recipe for 5 people, Required Gulf shrimp = 1\dfrac14 cups

Since, 1\dfrac14=\dfrac{5}{4}

Required Gulf shrimp = \dfrac54 cups

Then, for 1 people Gulf shrimp required = \dfrac{5}{4}\div 5

=\dfrac54\times\dfrac{1}{5}

=\dfrac14 cup

For 12 people, it is required = 12\times\dfrac14 = 3\text{ cups}

Hence, 3 cups of gulf shrimp is required for new recipe.

So, correct option is C. 3 cups

Solve cos(2x + 30) = 0.5 for -180≤x≤180​
mrs_skeptik [129]

Answer:

<em>x = 15°</em>

<em>x = 135°</em>

<em>x = -45°</em>

<em>x = -180°</em>

Step-by-step explanation:

<u>Trigonometric Equations</u>

Solve

cos(2x + 30°) = 0.5 for -180° ≤ x ≤ 180°

Applying the inverse cosine function:

2x + 30° = arccos(0.5)

There are several angles whose cosine is 0.5. They are 60°, 300°, -60° and -300°, thus we have these candidate solutions:

2x + 30° = 60°

2x + 30° = 300°

2x + 30° = -60°

2x + 30° = -300°

Subtracting 30° to all the equations:

2x = 60° - 30° = 30°

2x = 300° - 30° = 270°

2x = -60° - 30° = -90°

2x = -60° - 300° = -360°

Dividing by 2 we have the complete set of solutions:

x = 15°

x = 135°

x = -45°

x = -180°
