Answer:
Choice D:
Step-by-step explanation:
If we check them one by one...
Choice A is all correct, so we leave that there for now
Choice B's 3x12 is equal to 36, so therefore it's wrong
Choice C has the same mistake as Choice B - 3x12 is not equal to 32
Choice D is all correct, so therefore it is the answer
Though Choice A is also correct, the question asked for <u>all</u> of the different ways you can arrange the cars
So, therefore... the answer is A!

Given was <span><span>cotθ</span>=−<span>21</span></span> and cot is the reciprocal of tan
therefore
<span><span>tanθ</span>=<span>1<span>−2</span></span></span>
solve for the hypotenuse c since t he opposite side <span>a=1</span> and the adjacent sides <span>b=−2</span> were already given. that is,
<span><span>c2</span>=<span>a2</span>+<span>b2</span></span>
<span>c=<span>√<span><span><span>(1)</span>2</span>+<span><span>(−2)</span>2</span></span></span></span>
<span>c=<span>√5</span></span>
Solving for <span>sinθ</span>
<span><span>sinθ</span>=<span><span>oppositesides</span><span>hypoteνse</span></span>=<span>ab</span></span>
<span><span>sinθ</span>=<span>1<span>√5</span></span></span> need to rationalize
<span><span>sinθ</span>=<span>(<span>1<span>√5</span></span>)</span>×<span><span>√5</span><span>√5</span></span></span>
<span><span>sinθ</span>=<span><span>√5</span>5</span></span>
Note that the adjacent side of the angle is <span>−2</span> so the angle
θ is found in the <span>2nd</span> quadrant.
Answer:What does point F represent in this context
Step-by-step explanation:Interpret complicated expressions in context, understanding the meaning of specific terms, factors, and coefficients. Interpret expressions that represent a quantity in terms of its context. Interpret parts of an expression, such as terms, factors, and coefficients.
<h3>
Answer: 168 square cm</h3>
==============================================
Work Shown:
- L = 2 = length
- W = 6 = width
- H = 9 = height
The order of length, width and height doesn't matter
SA = surface area of rectangular prism
SA = 2*(LW + LH + WH)
SA = 2*(2*6 + 2*9 + 6*9)
SA = 2*(12 + 18 + 54)
SA = 2*(30+54)
SA = 2*(84)
SA = 168 square cm
