The exact value of sin θ  and cos θ  is: sinθ =(√105)/19 and cosθ =16/19

The terminal side of an angle is the angle at the standard position. The terminal side of an angle θ drawn in angle standard position is the side which isn't the initial side.

Given that the point of intersection of the terminal side of θ an the unit circle is:

(16/19,y)

The exact value of sin θ  and cos θ  is: sinθ =(√105)/19 and cosθ =16/19

The given parameters is represented by:

(16/19,y)

This means that :

(cosθ ,sinθ )=(16/19,y)

Using the following trigonometric identity:

cos²θ +sinθ =1

We have:

(16/19)²+y²=1

Expand fraction:

(256/361)+y²=1

Collect like terms:

y²=1-(256/361)

Take LCM:

y²=(361-256)/361

y²=105/361

Take square roots

y=(√105)/19

Substitute value for y in

(cosθ ,sinθ )=(16/19,y)

By comparison:

cosθ =16/19

sinθ =(√105)/19

So the exact value of sin θ  and cos θ  is: sinθ =(√105)/19 and cosθ =16/19

Alonzo, Alice, and Juan all solved the following problem but got different answers:
r-ruslan [8.4K]

Answer:

Juan believes the answer is -2/15.

Step-by-step explanation:

The given problem is :

\dfrac{-1}{3}\times \dfrac{2}{5}

We need to solve the problem.

\dfrac{-1}{3}\times \dfrac{2}{5}=\dfrac{-1\times 2}{3\times 5}\\\\=\dfrac{-2}{15}

So, the answer to the problem is \dfrac{-2}{15}. Hence, Juan is correct.

A football field measures 120 yards long and 54 yards wide. We know that the team can fit 26 players in 5 yards by 8 yards box.
wariber [46]

Answer:

4,212 people

Step-by-step explanation:

We are given;

  • Dimensions of the football field are 120 yards by 54 yards
  • 26 players can fit in a box measuring 5 yards by 8 yards

We are required to determine the number of people that can fit in the football field.

  • We are going to get the area of the field first;

Area = length × Width

Area of the field = 120 yards × 54 yards

                          =  6480 square yards

  • Then we get the area of the box

Area of the box = 5 yards × 8 yards

                           = 40 square yards

  • We then determine the number of boxes that can fit in the football field

Number of boxes = Area of the foot ball field ÷ Area of one box

                             = 6480 sq yards ÷ 40 sq yards

                             = 162 boxes

But, 26 people can fit in one box

Therefore,

Total number of people that can fit in the field is given by multiplying the number of boxes that can fit in the field by the number of people in a box

That is, Number of people = 26 players × 162 boxes

                                            = 4,212 people

Therefore, the number of people that can fit in the football field is 4,212 people.
