What is the range of y=log8x, ? all real numbers less than 0 all real numbers greater than 0 all real numbers not equal to 0 all real numbers

The range of y= log 8x is all real values .

Step-by-step explanation:

Range is the set of all defined values of y correspond to the domain.

The given function y= log 8 x = log 8+log x=

where domain of log x= {x∈R|x>0} =(0,∞)  , all positive real values.

and Range={y|y∈R}=(-∞,∞) i.e.all real values.

Therefore range of y=log8x would be same as of logx such that

Range of y={y|y∈R}=(-∞,∞) i.e.all real values.

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
