Answer:

h=7

Step-by-step explanation:

We want to solve the equation:

\frac{1}{h-5}+\frac{2}{h+5}=\frac{16}{h^2-25}

We multiply through by the LCM: h^2-25=(h+5)(h-5)

(h^2-25*\frac{1}{h-5}+(h^2-25)*\frac{2}{h+5}=\frac{16}{h^2-25}   \times(h^2-25)

Simplify to get:

h+5+2(h-5)=16

We expand to get:

h+5+2h-10=16

h+2h=16+10-53h=21

h=7

Which expression converts 8 radians to degrees? 8 times pi 8 times StartFraction pi Over 180 degrees EndFraction 8 times 180 deg
tensa zangetsu [6.8K]

Answer:

The expression that converts 8 radians to degree is: degrees = (8 rad)*180/pi

Step-by-step explanation:

To convert any number from radians to degrees we must use the equation below:

degrees = radians*180/pi

Therefore to convert 8 radians to degree we need to apply this value to the formula above:

degrees = 8*180/pi

degrees = 1440/pi

degrees = 458.366º

The expression that converts 8 radians to degree is: degrees = (8 rad)*180/pi
