2. An Evergreen Eagle flies about 13 meters in one second. How many kilometers could it fly in 20 minutes? *
Salsk061 [2.6K]

Answer:

Evergreen Eagle can will fly 1.56 km in 20 minutes.

Step-by-step explanation:

Speed of Evergreen Eagle = \frac{\text{Distance}}{\text{Time}}

                                            = \frac{13}{1}

                                            = 13 meters per second

With this speed Eagle can fly the distance in 20 minutes Or 120 seconds

= Speed × Time

= 13 × 120

= 1560 meters

Since, 1000 meters = 1 Km

1 meter = \frac{1}{1000} km

Therefore, 1560 meters = \frac{1560}{1000}

                                       = 1.56 km

Therefore, Evergreen Eagle can will fly 1.56 km in 20 minutes.

If sinxcos(pi/7)-sin(pi/7)cosx=-sqrt2/2 then x can equal?
Rom4ik [11]
I'm going for a range of 0 < x <2<span>π

This is R sin (x-a), although R is 1.

a = </span><span>π/7, so 

=> sin (x-(</span><span>π/7)) = -1/(sqrt(2))
=> x = 53</span>π/28, 39<span>π/28</span>
