Mathematics
1 answer:
Anika [276]2 years ago
4 0

Answer:

t = 7 + 3i

Step-by-step explanation:

(t-7)^2 + 18 = 9

(t-7)^2 = 9 - 18

(t-7)^2 = -9

(t-7) = sqrt(-9) = |3| sqrt(-1)

t = 7 + 3i

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

The bonus Tom receives is 30% of £96

Tom's bonus

=  \frac{30}{100}  \times 96

= 28.8

So the bonus Tom received is £28.8

From the question, Sally gets a bonus of £31.40
