Answer:
The answer to your question is 
Step-by-step explanation:
Data
cos Ф = 3/5
tan2Ф = ?
Quadrant IV
Process
1.- Remember that tanФ =
and cos Ф = 
then, adjacent side = 3 and hypotenuse = 5
2.- Calculate opposite side
O² = h² - a²
O² = 5² - 3²
O² = 25 - 9
O² = 16
O = 4
3.- Calculate the tan 2Ф
tan 2Ф = 2(
) The opposite side is negative in the fourth
quadrangle
tan 2Ф = 
Answer:
[-5, 4) ∪ (4, ∞)
Step-by-step explanation:
Given functions:


Composite function:
![\begin{aligned}(f\:o\:g)(x)&=f[g(x)]\\ & =\dfrac{1}{\sqrt{x+5}-3} \end{aligned}](https://tex.z-dn.net/?f=%5Cbegin%7Baligned%7D%28f%5C%3Ao%5C%3Ag%29%28x%29%26%3Df%5Bg%28x%29%5D%5C%5C%20%26%20%3D%5Cdfrac%7B1%7D%7B%5Csqrt%7Bx%2B5%7D-3%7D%20%5Cend%7Baligned%7D)
Domain: input values (x-values)
For
to be defined:


Therefore,
and 
⇒ [-5, 4) ∪ (4, ∞)
This answer should be the third one
Step-by-step explanation:
let star be st and square be sq...
and. if two shapes are randomly chosen without replacement...
for first pick
p(st)=1/2
for second
p(sq)=1
that mean
probability of getting star at first and square at second is = p(st)*p(sq)=(1/2)*1=1/2
To answer this we will divide 32 (total elephants) by 4 (times more).
32 ÷ 4 = 8
Check your work:-
8 × 4 = 32
We were right! :)
So, there were 32 elephants.
Hope I helped ya!!!!!!!!!!
