Mary is solving the equation 2n – 3 = 83. her first three steps are shown:
step 1: 2n – 3 = 83
step 2: 2n = 86
step 3: ln 2n = ln 86

which shows step 4?
a.) ln 2 = nln 86
b.) n + ln 2 = ln 86
c.) nln 2 = ln 86
d.) n = ln 86 – ln2

10 glasses of juice could be made with 5 carrots, 1,500 orange juice, 2,000 papaya juice.

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
