Solve the equation for x, where x is restricted to the given interval. y= 8 cos 3x, for x in[0, pi/3] x = 1/3 y/8 x= 1/8 y/3 x= 5 y/3 x= 3 y/8 Use a calculator to give the value to the nearest degree. theta - sin^-1(0.8830) 57 degree 62 degree 60 degree 118 degree Write the product as a sum or different of trigonometric functions. 2 sin 2x sin 12 x cos 14x + cos 10x 1/2(cos 14x + cos 10x) sin 14x + sin 10x cos 10x - cos 14x Find the value of the real number y. y = cos^-1[squarerrot 2/2] pi/4 11 pi/6 7 pi/4 pi/6 Use Identities to find the exact value. cos 165 degree - squareroot 6 - squareroot 2/4 squareroot 2 - squareroot 6/4 squareroot 6 - squareroot 2/4 squareroot 6 + squareroot 2/4

Solve for n<br> 2/5n+3-7/10n=3/5-3n

LuckyWell [14K]

<h2>The answer is " $-\frac{8}{9} \\\\$ ".</h2>

Given:

$\to \frac{2}{5}n+3-\frac{7}{10}n=\frac{3}{5}-3n$

To find:

n=?

Solution:

$\to \frac{2}{5}n+3-\frac{7}{10}n=\frac{3}{5}-3n\\\\\to \frac{2}{5}n-\frac{7}{10}n+3n=\frac{3}{5} -3\\\\\to n(\frac{4-7+30}{10})=\frac{3-15}{5} \\\\\to n(\frac{-3+30}{10})=\frac{3-15}{5} \\\\\to n(\frac{27}{10})=\frac{-12}{5} \\\\\to n=\frac{-12}{5} \times \frac{10}{27} \\\\\to n=-4 \times \frac{2}{9} \\\\\to n=-\frac{8}{9} \\\\$

Therefore, the final answer of n is " $-\frac{8}{9} \\\\$ ".

What is 2 3/8 * 1/3. Estimate the product

stealth61 [152]

2 3/8 x 1/3 I believe? First you need to change 2 into a 16 then add that into 3 which is 19/8. You multiply across with 1/3 like with numerator with numerator and denominator with denominator. That then equals:19/24. You can't estimate it because 19 is a prime number.
