A tornado drops a piece of wood from a height of 4,624 ft. If the equation for
height as a function of time is
h(t) = -16t2 + initial height where t is time
in seconds and h(t) is height in feet, how
many seconds will it take for the piece of
wood to hit the ground?

Step-by-step explanation:

H(t) =  -16+4.624  ( in feet)

0 = -16 + 4,624

-4,624 =  -16

-4,624 / -16 =

289 =

17 = t

so.. 17 seconds to hit the ground..  :)

the answer to your question a or b but i am pretty sure it is b. i hope this : )

step-by-step explanation:

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
