Answer: 14 Hours
Step by step:
Start by listing the information from the problem.
The spaceship's average speed is 8 kilometers per second. You can write this as a fraction in two ways:
8 km
1 sec
or
1 sec
8 km
.
The spaceship needs to travel 403,200 kilometers.
The problem asks how long it will take the spaceship to travel 403,200 kilometers. The spaceship is moving at a rate of
1 sec
8 km
. Multiply so that the kilometers cancel out. The result will be in seconds.
403,200km
1sec
8km
=
403200kmsec
8km
=50400 sec
Now you know it will take the spaceship 50,400 seconds to reach the moon, but the problem asks about hours. So, convert the seconds to hours. If you don't know how many seconds are in an hour, you can first convert the seconds to minutes.
There are 60 seconds in 1 minute, so multiply by
1 min
60 sec
. The result will be in minutes since the units of seconds cancel out.
50,400sec
1min
60sec
=
50400secmin
60sec
=840 min
Now convert 840 minutes to hours. There are 60 minutes in 1 hour, so multiply by
1 hr
60 min
.
840min
1hr
60min
=
840minhr
60min
=14 hr
It will take the spaceship 14 hours to get to the moon.
It would take about 25 months for the cost of leasing a billboard be the same for both companies.
<h3>
Linear function</h3>
A linear function is in the form:
y = mx + b
Where y,x are variables, m is the rate of change and b is the initial value of y.
Let P represent the cost to lease a billboard from a different company for x months. Given that:
P(x) = 100x
For the second company, let C represent the cost, hence using the table point (1, 580) and (5, 900):
C - 580 = [(900 - 580)/(5 - 1)](x - 1)
C = 80x + 500
For the same cost:
100x = 80x + 500
x = 25 months
It would take about 25 months for the cost of leasing a billboard be the same for both companies.

Answer:
Step-by-step explanation:
Given
Solving (a): Set of ordered pair
A function y = f(x) is represented as (x,y)
So, the ordered pair of V is:
Order the alphabets in increasing order
Solving (b): The domain and the range
In a function 
The domain and the range are represented as:
So, we have:
B because the variable (x) is not raised to any power.
City A = -96
City C= -24
City D = -24/4
Expression is above
Final answer is -6 because city C is below sea level it is negative and then 1/4 of -24 is -6.
Please mark brainiest and good luck :D
