1. an object is projected from the ground with an initial velocity 100 meters per second and its x and y
displacements have the functions:
(t) = 60t, y(t) = 80t – 5t
(a) find the object's speed at t= 1 second.
(b) what's the maximum height the object can reach?
(c) what's the maximum horizontal distance?

2. for the function f(x) = ez? +2, find the equation of the tangent line to the graph of the function at the
point (0, 1).

sorry i dont know my friend

72 fudge and 75 toffee

step-by-step explanation:

i hope this : )

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
