Divide 11 1/4 by 2.

Mathematics
1 answer:
Scilla [17]3 years ago
5 0

Answer:

the answer is 5 5/8

Step-by-step explanation:

if you make 11 1/4 into an improper fraction, you get 45/4 (this fraction simplified would give you your original mixed number). Using the keep, change, flip rule, you would multiply 45/4 by 1/2, giving you 45/8. This fraction simplified is your answer, 5 5/8.

Write the smaller solution first, and the larger solution second. h(x)=-5x^2 +180h(x)=−5x 2 +180
katrin2010 [14]

Answer:

x = -6,6

Step-by-step explanation:

h(x)=−5x^2 +180

Assuming you want to find the zero's

0 =−5x 2 +180

Subtract 180 from each side

0-180=−5x^2 +180-180

-180 = -5x^2

Divide each side by -5

-180/-5 = -5x^2/-5

36 = x^2

Take the square root of each side

±sqrt(36) = sqrt(x^2)

±6 = x

x = -6,6

Find the exact value
Mnenie [13.5K]

By using properties for <em>trigonometric</em> functions and <em>trigonometric</em> expressions, we find that the <em>exact</em> value of the sine of the angle 5π/12 radians is \frac{\sqrt{2+\sqrt{3}}}{2}.

<h3>How to find the exact value of a trigonometric expression</h3>

<em>Trigonometric</em> functions are <em>trascendent</em> functions, these are, that cannot be described algebraically. Herein we must utilize <em>trigonometric</em> formulae to calculate the <em>exact</em> value of a <em>trigonometric</em> function:

\sin \frac{5\pi}{12} = \sqrt{\frac{1 - \cos \frac{5\pi}{6} }{2} }

\sin \frac{5\pi}{12} = \sqrt{\frac{1 + \cos \frac{\pi}{6} }{2} }

\sin \frac{5\pi}{12} = \sqrt{\frac{1 + \frac{\sqrt{3}}{2} }{2} }

\sin \frac{5\pi}{12} =  \sqrt{\frac{2+\sqrt{3}}{4} }

\sin \frac{5\pi}{12} = \frac{\sqrt{2+\sqrt{3}}}{2}

By using properties for <em>trigonometric</em> functions and <em>trigonometric</em> expressions, we find that the <em>exact</em> value of the sine of the angle 5π/12 radians is \frac{\sqrt{2+\sqrt{3}}}{2}.
