1

1 + 0 = 1

1 + 1 = 2

1 + 2 = 3

2 + 3 = 5

3 + 5 = 8

5 + 8 = 13

8 + 13 = 21

13 + 21 = 34

21 + 34 = 55

1, 1, 2, 3, 5, 8, 13, 21, 34, 55

Hope this helps! :)

A jeepney ride cost 11 pesos for the first 4 kilometers and each additional integer kilometers adds 3.50 pesos to the fare, use
Nookie1986 [14]

Answer:

f(d)=\left\{ \begin{matrix} 11 & \text{for} & 0< d\leq 4  \\-3+3.5d & \text{for}&  d > 4  \end

Step-by-step explanation:

Cost of first 4 kilometers ride = 11 pesos.

So, for the first 4 km, the fair is constant i.e.

for 1 km the fare is 11 pesos,

for 2 km the fair is also 11 pesos,

similarly, for 3 km of 4 km, the fare is 11 pesos.

Hence, for the distance 0\geq d\geq 4, the fair function,

f(d)=11\cdots(i)

After 4 km, there is an increment of $ 3.50 for each kilometer.

So, the fare function up to 5 kilometers,

f(d)=11+3.5=14.5

So, the fare function up to 6 kilometers, i.e for the distance 5,

f(d)=11+2\times3.5=18

This can be arranged as the fare function up to 6 km,

f(d)=11+(6-4)\times3.5=18

Similarly, the fare function up to d kilometer (n>4),

f(d)=11+(d-4)\times3.5

\Rightarrrow f(d)=-3+3.5d\cdots(ii)

Hence, from equations (i) and (ii),

f(d)=\left\{ \begin{matrix} 11 & \text{for}\; 0< d \leq 4  \\-3+3.5d & \text{for}\;  d > 4  \end

How is scientific notation useful in the real world?
grin007 [14]

Answer:

You're less likely to make mistakes reading or writing very big and very small numbers if you use scientific notation. It also makes it much easier to tell at a glance which numbers are bigger or smaller without counting long strings of zeros.
