Mathematics
1 answer:
Brilliant_brown [7]3 years ago
5 0

Answer:

<u>Exponential function:</u>

  • f(x) = abˣ

<u>Use the given data to determine the function.</u>

  • f(0) = ab⁰ = a*1 = a ⇒ a = 0.75
  • b = 2 as each of the f(n) is twice the previous one in series.

<u>The model is:</u>

  • f(n) = 0.75*2ⁿ

<u>Recursive rule to reflect this is:</u>

  • f(0) = 0.75
  • f(n) = 2*f(n-1)

The table shows the distance Randy drove on one day of her vacation
horsena [70]
Given the table showing the distance Randy drove on one day of her vacation as follows:

\begin{tabular}&#10;{|c|c|c|c|c|c|}&#10;Time (h)&1&2&3&4&5\\[1ex]&#10;Distance (mi)&55&110&165&220&275&#10;\end{tabular}

The rate at which she travels is given by

rate= \frac{distance}{time}  \\  \\ = \frac{55}{1} =55mi/h

If Randy has driven for one more hour at the same rate, the number of hours she must have droven is 6 hrs and the total distance is given by

distance = 55 x 6 = 330 miles.

Marco starts with a population of 10 bacteria that doubles every day for a number of days, d. He writes the expression 10(2d) to
riadik2000 [5.3K]

Answer:

Marco- 10 is the starting value of the population. 2 is the growth rate of "double each day" with d as an exponent.

Isabella- 1 is the starting population. 1+0.2=1.2 is the rate at which it grows each day.

Step-by-step explanation:

Marco's equation should be 10(2^{d}) since the bacteria double each day. 10 is the starting value of the population. 2 is the growth rate of "double each day" with d as an exponent. This will double each day because:

Day 1 is 2^{1}=2

Day 2 is 2^{2}=4

Day 3 is 2^{3}=8

Day 4 is 2^{4}=16

You'll notice the value doubles each day.

Isabella has a different equation because her population increases by a percentage. We use the simple interest formula to calculate the bacteria's daily increase or interest.

1(1+0.2)d

1 is the starting population.

1+0.2=1.2 is the rate at which it grows each day.
