Step-by-step explanation:

Step-by-step explanation:

Express as a single logarithm

ln(a)+1/2ln(b)

2ln4-ln2

n a + (1/2) ln b

= lan a + ln )b^(1/2))

= ln (a√b)

you try the second, and let me know what you got

2ln4-ln2

=ln(16)-ln2

=ln(16/2)

=ln8?

i think is g(1)=-1.

hope that i can

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
