evaluate 4^3 / 4^5

4^-2=1/16

Step-by-step explanation:

When dividing powers that have the same base, subtract the exponents.

So 4³/4⁵ is the same as 4³ ⁻ ⁵ or 4⁻².

When we have a base taken to a negative exponent,

it means the same thing as 1 over the base to the positive exponent.

In other words, we can rewrite 4⁻² as 1/4² or 1/16.

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
