Given that Martin throws a ball straight up in the air.
The equation gives the height of the ball, in feet, t seconds after martin releases it.
We need to determine the time that it takes the ball to hit the ground.
<u>Time taken:</u>
To determine the time 't', let us equate h(t) = 0 in the equation
Thus, we have;
Switch sides, we get;
Now, we shall solve the equation using the quadratic formula.
Thus, we have;
Solving, we get,
Cancelling the common terms, we get,
Thus, the roots of the equation and
Simplifying the roots, we get,
and
and
Since, t cannot take negative values, then
Hence, It takes 2.6 seconds for the ball to hit the ground.
Answer:
equals 22.
Step-by-step explanation:
For every input in a function, there will be one corresponding output. When taking the output of the function and inserting it as the input to the inverse function of the original, the output will be equivalent to the exact input of the original function. In this case, because , that means
will equal 7. Using this knowledge, you can find the value of
, which will be
, so
equals 22.
