Mathematics

To estimate it, you just have to think. 879 is basically 900. 9 x 8 is 72 and then annex the two zeroes, getting roughly 7,200.

Which of the trigonometric ratios has a value that is undefined?
FinnZ [79.3K]

Answer:

\tan \left(\frac{\pi }{2}\right)

Step-by-step explanation:

We know that  tan(x) is defined as  sin(x)/cos(x):

\tan \left(\frac{\pi }{2}\right),\\\sin \left(\frac{\pi }{2}\right)=1,\\\cos \left(\frac{\pi }{2}\right)=0,\\\\

\tan \left(\frac{\pi }{2}\right) = 1/0 \\

1/0 is undefined as 0 is in the denominator

A soccer ball is kicked into the air from the ground. If the ball reaches a maximum height of 25 ft and spends a total of 2.5 s
OLga [1]
Hello,

g=9.81m/s²= 9.81/0.3048 =32.18.. ft/s² rounded to 32

h=-g/2*t²+vt+h0
if t=0,h=0 ==>h0=0

==>h=-16*t²+vt
50 ft in 2.5s ==> 25 ft in 1.25s

25=-16*1.25²+v*1.25
==>v=50/1.25=40

Equation h=-16t²+40*t
