marusya05 [52]

Answer:

97, 98

Step-by-step explanation:

a = first number

a + 1 = consecutive number

Option A: All real numbers is the right answer

Step-by-step explanation:

First of all, let us define domain

Domain is the set of all inputs to a function on which the function is defined

So

Given function is:

f(x) = 5.3^x

The given function will not be undefined for any value of x as there is no denominator which will make the function approach infinity

Hence,

Option A: All real numbers is the right answer

Keywords: Domain, functions

kenny6666 [7]

Answer:

The Federal taxes of total budget is 30%

C is correct.

Step-by-step explanation:

The chart below summarizes Ralph's annual expenses for the upcoming year.

We need to find the percentage for federal taxes.

First we find total annual budget from chart. We will add all the taxes.

Total annual budget = Federal taxes + State tax + Housing +  Food + Medical +  

                                     Transportation + Recreation

Total Annual Budget = 18380 + 3448 + 15000 + 4880 + 6652 + 4332 + 3500 +

                                       3260 + 1750

                                  =  61202

Total Annual Budget = $61,202

           Federal Taxes =  $18,380

Now, we will find the percentage of federal taxes.

            % of federal taxes =\dfrac{18380}{61202}\times 100

                                           =30.03\approx 30\%

Hence, The Federal taxes of total budget is 30%
