Answer:
D
Step-by-step explanation:
I think 'D' will be the correct answer for you!
So which is equivilentpemdas
(8-6x+12)(20-6x)multiply/distribute1/4(20-6x)5-6/4x=5-3/2x=-3/2x+5
the answer is D
so mean is equivilent to average
per minute means x feet for every one minute=xfeet/1miin=x/1
so just divide -378/7=-54
mean change in altitude-54 feet per minute
Answer:40.85
Step-by-step explanation:
43x5/100=2.15
43-2.15= 40.85
Answer: Choice A) 4, 3, 5, 1, 2
=====================================================
Explanation:
Since tan(x) = sin(x)/cos(x) is a known and widely used trig identity, this must mean step 4 goes first.
The answer is between choice A and choice B.
The question is now: What is the correct second step?
It's either step 3 (choice A) or step 5 (choice B)
It turns out that step 3 is the correct statement after step 4. The sin(2x) breaks up into 2sin(x)cos(x), while the cos(2x) breaks up into cos^2(x)-sin^2(x). There are three different variations for the cos(2x) and this just happens to be one of them.
So we can rule out choice B and go with choice A as the final answer.
