Answer:
56
Step-by-step explanation:
Because when you want to find the erea of something you mutiply the width and length
length=long
with=wide
7 meters long, length × 8 meters wide,with
length×with
7×8=
=56
Answer: the correct answers is 0.35 or 7/20
Step-by-step explanation:
Answer:
1/3
Step-by-step explanation:
differentiate first equation to get t , then replace t with 1/3
The exact value is
<span>sin<span>(arccos<span>(<span>3/4</span>)</span>)</span></span>The equation for cosine is <span>cos<span>(A)</span>=<span>AdjacentHypotenuse</span></span>. The inside trig function is <span>arccos<span>(<span>3/4</span>)</span></span>, which means <span>cos<span>(A)</span>=<span>3/4</span></span>. Comparing <span>cos<span>(A)</span>=<span>AdjacentHypotenuse</span></span> with <span>cos<span>(A)</span>=<span>3/4</span></span>, find <span>Adjacent=3</span> and <span>Hypotenuse=4</span>. Then, using the pythagorean theorem, find <span>Opposite=<span>√7</span></span>.<span>Adjacent=3</span><span>Opposite=<span>√7</span></span><span>Hypotenuse=4</span>Substitute in the known variables for the equation <span>sin<span>(A)</span>=<span>OppositeHypotenuse</span></span>.<span>sin<span>(A)</span>=<span><span>√7</span> over 4</span></span>Simplify.<span><span>√7</span><span> over 4</span></span>
2.6 x 6 = $15.6 . That’s the answer I’m pretty sure! Goodluck!
