That's a typo...if the acceleration of gravity is -16ft/s^2???  Maybe basketball on Mars :P

Free fall equation result from integration of the acceleration equation with respect to time...

a=g

v=gt+v0

h=gt^2/2+v0t+h0 where v0 and h0 are initial velocity and height respectively..

Since acceleration, g, is about -32ft/s^2 not -16ft/s^2 you get:

h=-16t^2+36t+4 for your height equation. 

h(2)=12 ft

What is the sST for the data set (1, 5), (2, 8), (4, 14)?<br><br> 14<br> 42<br> 25<br> 9
ohaa [14]

Answer:

42

Step-by-step explanation:

SST = ∑ ( y − ¯ y ) ² (¯ y = mean of y values)

¯ y = (5+8+14)/3 = 27/3 = 9

∑ ( y − ¯ y ) ² =  ( 5 − 9 ) ² +  ( 8 − 9 ) ² +  ( 14 −9 ) ²

=  (  − 4 ) ² +  (  − 1 ) ² +  ( 5 ) ²

= 16 + 1 + 25

= 42

Help me find the missing angles
Keith_Richards [23]

Answer:

  b) 105°

  d) 130°

Step-by-step explanation:

An external angle has the same measure as the sum of the remote internal angles.

b) ? = 25° +80° = 105°

d) ? = 35° +95° = 130°

_____

This should be fairly obvious if you consider that the adjacent internal angle together with the external angle totals 180°, and the adjacent internal angle together with the other two internal angles totals 180°.

If the two "remote" angles are A and B, and the adjacent internal angle is C, then we have in symbols ...

  A + B + C = 180° = ? + C

If we subtract C, then we find ...

  A + B = ? . . . . . . the fact we used above

Answer:

C) 35 Degrees

Step-by-step explanation:

To find the degree of an exterior angle, subtract the larger arc, DE, degree by the smaller arc, BC, and then divide by 2! Which is 35. 118-48/ 2 = 35.
