Step-by-step explanation:
8% = 0.08
60 * (1 + 0.08) = $64.80
Step-by-step explanation:
Quotient of s and r is s/r
s/r to the 3rd power = (s/r)^3
Answer:
c
Step-by-step explanation:
Given the roots are x = - 1 + 4i and x = - 1 - 4i then the factors are
(x - (- 1 + 4i))(x - (- 1 - 4i))
= (x + 1- 4i )(x + 1 + 4i )
= (x + 1)² - 16i² → [ i² = - 1 ]
Expand and simplify
= x² + 2x + 1 + 16
Hence
x² + 2x + 17 = 0 → c
You pretty much just count the number of numbers being multiples and have that number as the exponent, for number 1. There are three 3's so the answer would be 3^3, (three to the third power)
