Answer:

M = -2

Step-by-step explanation:

7 (M + 5) = 21

7M + 35 = 21

7M = 21 - 35

7M = -14

M = -14/7

M = -2

A student dropped a textbook from the top floor of his dorm and it fell according to the formula s(t) = −16t 2 + 8√t , where t i
Sidana [21]

Answer:

<h2>-29.61m/s</h2>

Step-by-step explanation:

Given the distance of fall of the student in term of the time t expressed by the equation s(t) = −16t² + 8√t, to get the average speed of fall of the pencil after 2.8 secs, we will need to differentiate the given function first since Velocity is the change in distance of a body with respect to time i.e

V = d(s(t))/dt

s(t) = −16t² + 8t^1/2

V = -32t+1/2(8)t^(1/2 - 1)

V = -32t+4t^-1/2

The average speed of the fall Using the fact that the pencil hit the ground in exactly 2.8 seconds, will be gotten by substituting t = 2.8 into the resulting equation.

V = -32t+4(2.8)^-1/2

V = -32t+4/√2.8

V = -32+4/1.6733

V = -32+2.391

v = -29.61m/s

<em>Hence the average speed of the fall is -29.61m/s</em>

Vesna [10]

Answer:

Miguel cabrera

Step-by-step explanation:

Given that :

Miguel cabrera's batting average = 0.33

Mike trout's batting average = 0.326

The average for both players was obtained during the same season:

Hence. Comparing their respective averages,

0.33 = 0.330

0.330 > 0.326

Hence, Miguel Cabrera's batting average is higher than that of Mike trout
