A sequence of transformations maps ∆ABC onto ∆A″B″C″. The type of transformation that maps ∆ABC onto ∆A′B′C′ is a reflection
.

When ∆A′B′C′ is reflected across the line x = -2 to form ∆A″B″C″, vertex
of ∆A″B″C″ will have the same coordinates as B′.

Aball is thrown from a height of 139 feet with an initial downward velocity of 15 ft/s. the ball's height h (in feet) after t seconds is given by the following. h=139-15t-16t^2 how long after the ball is thrown does it hit the ground? round your answer(s) to the nearest hundredth. (if there is more than one answer, use the "or" button.) t =

If f(x)=x+7 and g(x)=1/x what is (fog)(x)
