Answer: think were a week late
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
The difference formula for cosine is
cos(x - y) = cosxcosy + sinxsiny
Consider
cos75 = cos(120 - 45)°, then
cos(120 - 45)°
= cos120°cos45° + sin120°sin45° → C
The recursive geometric sequence that models this situation is:
<h3>What is a geometric sequence?</h3>
A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.
It can be represented by a recursive sequence as follows:
With f(1) as the first term.
In this problem, the sequence is: 90.000: 81,000; 72,900; 65,610, hence:
Hence:

There are 40 animals at a petting zoo.
Adult goats→x Child goats→a
Adult rabbits→y Child rabbits→b
<span>
There are twice as many adult rabbits as adult goats: y=2x
</span>There are three times as many child goats as adult goats: a=3x<span> There are exactly as many adult rabbits as there are child rabbits: b=y=2x
x+y+a+b=40⇒x+2x+3x+2x=40
8x=40⇒x=40/8⇒x=5
There are 5 </span><span> adult goats are in the petting zoo.</span>
The correct answer is 40 percent
