Answer:

Step-by-step explanation:

we would apply the law of Cosines which is expressed as

a² = b² + c² - 2abCosA

Where a,b and c are the length of each side of the triangle and A is the angle corresponding to a. Likening the expression to the given triangle, it becomes

x² = 16.5² + 24² - 2(16.5 × 25)Cos22

x² = 272.25 + 576 - 2(396) × 0.927

x² = 848.25- 734.184

x² = 114.066

x = √114.066

x = 10.7 to the nearest tenth

Answer:

The answer to your question is x = 10.7

Step-by-step explanation:

Data

side 1 = a = 16.5

side 2 = b = 24

side 3 = c = x

angle C = 22°

Process

-To solve this problem, use the law of cosines

      c² = a² + b² - 2abcosC

-Substitution

      c² = 16.5² + 24² - 2(16.5)(24)cos (22)

-Simplification

      c² = 272.25 + 576 - (792)(0.927)

      c² = 848.25 - 734.33

      c² = 113.92

-Result

      c = 10.67

The British Queen is to receive 4 foreign dignitaries. The digni- taries are sensitive to the order in which they are received.

Answer:

Number of Ways = ₄P₄ = 24

Step-by-step explanation:

Given that there are going to be 4 dignitaries, and that they are sensitive to the order (i.e the order of the dignitaries matter), hence the total number of ways they can be arranged can be found by permutating 4 dignitaries.

i.e

Number of Ways = ₄P₄ = 24

Pls help!!! evaluate the function for x=m/4
EastWind [94]
Plug in m/4 into the equation:

8 (\frac{m}{4})^{2} - 4(\frac{m}{4})

Solve the parentheses in the equation:

\frac{m}{4}^{2} = \frac{m}{4} \times \frac{m}{4} = \frac{m^{2}}{16}
8 \times \frac{m^{2}}{16} = \frac{8m^{2}}{16} = \frac{m^{2}}{2}

4 \times \frac{m}{4} = \frac{4m}{4} = m

Your equation should now look like this:

\frac{m^{2}}{2} - m

The answer is D.

e.)Since the line at 12 and the line at 9 meets then it is a perpendicular line.

c.)Perpendicular line.

a.)Perpendicular line.

b.)Parallel line.

d.)Depending on how they are faced if the ends of the telephone wire meets the second one then it is perpendicular but if not then it is parallel that's if they are in different directions which they can not meet.Thank you for the question
