Answer:

m∠T = 27.9°

Step-by-step explanation:

Use the law of cosines

$UV^{2} = TU^{2} + UV^{2} - 2(TU)(UV)cos T\\43^{2} = 88^{2} + 90^{2} - 2(88)(90) cos T\\1849 = 7744 + 8100 - 15840 cos T\\1849 = 15844 - 15840 cos T\\-13995 = - 15840 cos T\\cos T = \frac{-13995}{-15840} = .883522...\\T = arccos .883522... = 27.9$

Help on college algebra, question is on the picture!

$\frac{7x+1}{x-2} + \frac{2}{x} = \frac{-4}{ x^{2} -2x}$ is given
here , $\frac{7x+1}{x-2} + \frac{2}{x} = \frac{-4}{ x^{2} -2x}$
or, $\frac{7x^{2} +x +2x-4 }{x(x-2)} = \frac{-4}{ x^{2} -2x}$
or, $\frac{7 x^{2} +3x-4}{ x^{2} -2x} = \frac{-4}{ x^{2} -2x}$
or,7x²+3x-4=-4
or,7x²+3x=0
or,x(7x+3)=0
Either,x=0| Or,7x+3=0
|or,7x=-3
|or,x= $\frac{-3}{7}$
So , the solution set is S={0,- $\frac{3}{7}$ }

If f(x)=4x+9+2, which inequality can be used to find the domain of f(x

Ksju [112]

First off, the function above is incomplete, however, by the looks of it, likely a quadratic, anyway, the values "x" can safely take on would be all real numbers, thus -∞ < x < +∞
