An airplane is trying to fly at a speed of 300 miles per hour straight north, but a 70 miles per hour wind is blowing toward the west. what is the speed of the plane when these two velocity vectors are added together?

                          V = 308.06 miles/hour

                          θ = 13.13°  west of north.

Explanation:

Airplane speed = V₁ = 300 miles/hour    

Wind speed = V₂ = 70 miles/hour

Resultant speed of the plane = V = ?

As airplane is trying to fly straight North and wind is blowing toward the west. So the angle between airplane velocity and wind velocity is 90°.

By Pythagoras Theorem

                            V =

                            V =

                            V = 308.06 miles/hour

                            θ = tan⁻¹(70/300)

                            θ = 13.13°  west of north.

i believe it is b. what was the cause of the big bang

hope this !

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2
