Y/f(x) is greater than or equal to 5
Answer: 
Step-by-step explanation:
To solve this exercise it is important to remembet the definition Definition of a Logarithm:
If
and, 
, then
is equivalent to
(which is the exponential form).
Knowing this definition and having the following logarithmic equation:

You can identify that:

Therefore, susbtituting values into
, you can rewrite this equation as an exponential equation. Then:

We have to calculate how would it take for a red kangaroo to jump 2 km, if he jumps at a rate of 40 km/h.
Formula for the velocity is: v = d / t, where d stays for the distance and t stays for the time.
Therefore: t = d / v
t = 2 km / 40 km/h
t = 0.05 h = 3 minutes
Answer:
It would take 3 minutes.
The formula for the vertical height, h, attained with a vertical take off speed of u is
u² - 2gh = 0
where
g = 9.8 m/s², acceleration due to gravity.
Because h = 1.29 m, therefore
u² = 2*9.8*1.39 = 27.244
u = 5.2196 m/s
Also, the time of flight, t, required when the vertical take-off speed is u is given by
ut - 0.5gt² = 0.
Therefore
5.2196t - 0.5*9.8*t² = 0
5.2196t - 4.9t² = 0
t(5.2196 - 4.9t) = 0
t = 0, or t = 5.2196/4.9 = 1.0652 s
t = 0 corresponds to take-off.
t = 1.0652 s corresponds to landing.
The hang time is 1.0652 s.
Answer:
Take-off speed = 5.22 m/s (nearest hundredth)
Hang time = 1.065 s (nearest thousandth)
Answer:
C
Step-by-step explanation:
We know that there are 2 pairs of congruent angles, angles B and E along with the pair of right angles.
