The function h defined by h(t)+(49+4.9t)(10-t) models the height, in meters, of an object t seconds after it is dropped from a helicopter. From what height is the object dropped?

i believe

step-by-step explanation:

from my conclusion c

- 70

this is the answer for you hope it

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
