A standard working day is 8 hours, if you were to work 125% of a normal day, how many total hours would you work?

Elodia [21]

Answer:

10 hours

Step-by-step explanation:

It is given that,

Standard working day is 8 hours

If you were to work 125% of a normal day, then it means that,

$125\%\ \text{of}\ 8\ \text{hours}\\\\=\dfrac{125}{100}\times 8\\\\=10\ \text{hours}$

Hence, you will work for 10 hours.

The position of an object at time t is given by s(t) = 3 - 4t. Find the instantaneous velocity at t = 8 by finding the derivativ

zysi [14]

For this case, we have that the equation of the position is given by:
$s (t) = 3 - 4t
$
To find the velocity, we must derive the equation from the position.
We have then:
$s' (t) = - 4
$
Then, we evaluate the derivative for time t = 8.
We have then:
$s' (8) = - 4$
Answer:
the instantaneous velocity at t = 8 is:
$s' (8) = - 4$
