Which of the following numbers is a Mersenne prime? A: 90 B: 27 - 1 C: 211 - 1 D: 15

My name is Ann [436]

Answer:

B: 2⁷-1 = 127

Step-by-step explanation:

A Mersenne prime is a prime of the form 2^n -1, where n is also a prime.

Among the answer choices, neither 90=2·3²·5 nor 15=3·5 is prime. Both 2⁷-1 = 127 and 2¹¹-1 = 2047 are of the right form, but 2047 = 23·89 is a composite number.

2⁷-1 = 127 is a Mersenne prime

The company leased two manufacturing facilities. Lease A requires 20 annual lease payments of $200,000 beginning on January 1, 2

Fed [463]

Answer:

the present value of the lease obligation for lease A will be $1,702,712.74 while the present value of lease B will be $1,764,741.73

Step-by-step explanation:

the present value of annual lease payment will be determined by discounting the total amount to be received from lease payment over years.

for lease A , Pv = A $\fracA{1 -(1+r)^{-n} }{r}$

= $200,000( 1 - (1+0.1) $^{20}$ ) / 0.1 = $1,702,712.74

for lease B , Pv = $220,000( 1 - (1+0.1) $^-{17}$ ) / 0.1 = $1,764,741.73
