Answer:
Option B 0.5
Explanation:
I’ve attached my work
The process repeats for the remaining 2 points but you only need to do it for one (I did 2 just to show as an example)
I color coordinated to make it easier to show where each number came from
Hope this helps, Let me know if you have any questions !
Have a nice rest of your day :)

If a ball is thrown into the air with a velocity of 38 ft/s, its height in feet t seconds later is given by y = 38t − 16t2. (a)

tiny-mole [99]

Answer:

i.-34ft/s

ii.-27.6ft/s

iii.-26.8ft/s

iv-26.7ft/s

B.-26ft/s

Step-by-step explanation:

$average velocity = \frac{y_{2}-y_{1}}{t_{2}-t_{1}}\\$

For all cases the value of the initial time $t_{1} =2 seconds \\$

now we also use this time ti determine the value of the initial height in all cases

$y_{1}=38(2)-16(2)^{2} \\y_{1}= 12ft\\$

now when the time is increase by 0.5 seconds the new height becomes

$y_{2}=38(2.5)-16(2.5)^{2} \\y_{2}=-5fts\\$

the velocity becomes

$[tex]Average velocity = \frac{-5-12}{2.5-2}\\Average velocity = -34ft/s\\$

ii. when the time is increase by 0.1 seconds

the new height becomes

$y_{2}=38(2.1)-16(2.1)^{2} \\y_{2}= 10.66ft\\$

$Average velocity = \frac{10.66-12}{2.05-2}\\Average velocity = -27.6ft/s\\$

iii. when the time is increase by 0.05 seconds

the new height becomes

$y_{2}=38(2.05)-16(2.05)^{2} \\y_{2}= 9.24ft\\$

$Average velocity = \frac{9.24-12}{2.05-2}\\Average velocity = -26.8ft/s\\$

iv. when the time is increase by 0.1 seconds

the new height becomes

$y_{2}=38(2.01)-16(2.01)^{2} \\y_{2}= 11.73ft\\$

$Average velocity = \frac{11.73-12}{2.01-2}\\Average velocity = -26.7ft/s\\$ .

B. For us to determine the instantaneous velocity expression, we differentiate the expressing for the height

$V_{inst}=38-32t\\$

we now substitute t=2, we arrive at

$V_{inst}=-26ft/s\\$
