Answer:

32

Step-by-step explanation:

We need digits with only 0's and 1's.

There are 5 forms which we have to consider.

We have to consider 1-, 2-, 3-, 4-, 5-digit numbers.

1-digit number

For 1 digit number there is only 2 possibilities (0,1).

2-digit number

For 2 digit number the first digit will be fixed i-e 1 because if we take 0 to be the first digit it will reduce to one digit number, so first digit has to be 1. Now in the second digit place we have two possibilities 0 and 1.

So the total possible combination for 2-digit number is 1*2=2.

3-digit number

For 3 digit number first place is fixed with second and third having two possibilities giving us the combination for 3-digit number as 1*2*2=4.

4-digit number

Similarly for four digit number first place is fixed with the rest three with the possibility of two. So possible combination is 1*2*2*2=8.

5-digit number

For 5 digit we have the combination as 1*2*2*2*2=16.

So the total numbers left are 2+2+4+8+16=32.

The following graph represents the distance a commercial airplane travels over time, at cruising speed and an altitude of 35,000
ANEK [815]

Answer:

see the explanation

Step-by-step explanation:

<u><em>The picture of the question in the attached figure</em></u>

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form k=\frac{y}{x} or y=kx

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Let

x ----> the time in hours

y ----> the distance in miles

<em>Find the value of k</em>

For the point (4,2268)

k=\frac{2,268}{4}=567\ mph

The slope represent the speed of the airplane

so

The linear equation is

y=567x

Part 1 :

The point (0,0) represents the starting point of the aircraft, when the time and distance are equal to zero. The cruising starts when time t = 0.

Part 2 :

The  point  (4, 2268) represents the plane after 4 hours of cruise , and shows it has traveled a distance of 2268 miles after 4 hours
