Answer:

Remember, the formula is the second value minus the first value, divided by the first value times 100.

9. 50% Increase

10. 33% Decrease

11. 200% Increase

To calculate tip, simply move the decimal place 2 to the right and multiply it by the price. For example, If you want to leave a 20% tip, multiply the cost by 0.20 to get the tip amount or multiply the cost by 1.20 to get the total including tip.

12. $23.00

13. $10.50

Answer:

The correct option is B

Step-by-step explanation:

The equation of a line in point-slope form is:

y-y1 = m(x-x1)

where m is the slope and (x1,y1) a point on the line

here m=2 and (x1,y1)=(2,3)

substitute these values into the equation.

y-3 =2(x-2)

Thus the correct opttion is B....

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:
$s' (8) = - 4$
