Use a calculator to work these exercises. (See Examples 9 and 10.) Taxes Alabama state income tax for a single person in 2017 was determined by the rule T x = { .02 x if 0 ≤ x ≤ 500 10 + .04 ( x − 500 ) if 500 < x ≤ 3000 110 + .05 ( x − 3000 ) if x > 3000 , where x is the person’s taxable income. Find the following function values and interpret your answers. (Data from: www.tax-brackets.org.) T ( 100 ) T ( 2500 ) T ( 103 , 000 )

You are 3D printing six-sided dice for a Yahtzee tournament. After some research, you find out thatmost dice have a volume of 4 cm3each. An example of a single Yahtzee dice is illustrated below.Note that each side length, s, has the same measure.a(a) In the blank below, write the function that relates the volume of a single dice, V , and thedice’s side length, s.V (s) =(b) What is the perfect side length? i.e. What side length will result in a volume of 4 cm3? Youranswer should be written to 6 decimal places.s0=(c) Due to the nature of your 3D printer, the volume of each dice will be within 0.01 cm3 of 4cm3. Algebraically determine the interval around s0 that will ensure that correspondingoutput values are within 0.01 cm3 of 4 cm3. If you use decimals, your answer should bewritten to 6 decimal places.(d) What is the maximum amount of error that can occur on either side of s0 so that the volumevalues still lie within 0.01 of 4 cm3? (i.e. what is the δ value?) If you use decimals,…
2. The number of bacteria in a Petri dish increases by 18%
every hour. If there were initially 200 bacteria placed in
the Petri dish, which function can be used to determine
the number of bacteria in the Petri dish in
y = 200 (0.82)*
exactly x hours?
y = 200 (1.18)"
y = 200 (1.82)*
200 (0.18)"
