Answer:
answer is : Cos(13pi/8) = 0.3826
Step-by-step explanation:
We have, Cos (13pi/8)
Since 13pi/8 can be shown as 3pi/2 < 13pi/8 < 2pi
Hence 13pi/8 lies on fourth quadrant.
In fourth quadrant cosine will be positive.
Cos (13pi/8) = cos(3pi/2 + pi/8)
applying formula cos(A+B) = cos A cosB - sinAsinB
i.e Cos(3pi/2 + pi/8) = cos(3pi/2)cos(pi/8) - sin(3pi/2)sin(pi/8)
∵ Remember cos(3pi/2) =0 , sin(3pi/2) = -1
Cos(3pi/2 + pi/8) = 0 cos(pi/8) - (-1)sin(pi/8)
Cos(3pi/2 + pi/8) = 0 + 0.3826
Cos(3pi/2 + pi/8) = 0.3826
Hence we got Cos(13pi/8) = 0.3826
Answer:
The total distance covered in 1 hour is 4000 meters.
Step-by-step explanation:
The distance Ami'yan runs is 15 minutes = 1 kilometer
Using the unit formula,
The distance ran in 1 minute = 
Now, 1 hour = 60 minutes
⇒The distance covered in 60 minutes = 60 x (Distance run in 1 minute)
= 
So, the distance covered in 1 hour = 4 kilometer
1 kilometer = 1000 meters
⇒ 4 km = 4 x 1000 meters = 4000 m
Hence, the total distance covered in 1 hour = 4000 meters.
No, the one that Nayo draw was not a quadrilateral since the measurements given does not give a right triangle. The values 16,20 and 25 does not agree with Pythagorean Theorem. Hope this answers the question. Have a nice day. Feel free to ask more questions.
