What kinda of math is this so i can answer..
:)
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>
The answer will be 40 feet because w = 10 feet’s so it will decrease into 100
Step-by-step explanation:
10 gallons of gas is $29.50
10 gallons of gas = $29.50
10 gallons of gas / 10 = $29.50 / 10
1 gallon of gas = $2.95
Per x gallons of gas,
1 gallon of gas * x = $2.95 * x
x gallons of gas = $2.95 * x
Answer:
It would be 14 because since each book is 3.5cm thick times that by 4 and get 14.
