Answer:
Train A is faster by a factor of 1.01
Step-by-step explanation:
Given:
Train A:
Distance = 175 Miles
Time = 4 Hours
Train B:
y=43.5x
To Find:
which train travels at a faster rate in by what factor =?
Solution:
The speed of the train A =
The speed of train A =
The speed of train A = 43.75 miles per hour
Speed of the train B is the slope of the given line
The standard equation of the slope of the line is
y = mx+b
where m is the slope
and we are given with
y = 43.5x
So comparing with the standard equation
m = 43.5
Hence the speed of train B is 43.5 miles per hours
Train A travels faster
rate =1.01
I am rocking with C. Jasmine left class for head.
if im wrong let me know
That is false the opposite of 7 is -7
Answer:
Step-by-step explanation:
This scenario can be modeled using an exponential growth equation.
The exponential growth equations have the following form:
Where P is the population in year t
p is the initial population at t = 0
r is the growth rate
t is the time in years.
In this case we know that the current population is 13,000 and that the growth rate is 11%
So
The equation that models this scenario is:
Step-by-step explanation:
!
When Loss and Selling price ( SP ) are given , Cost price ( CP ) can be found out using the following formulae :
✰
?
We simply derived the formula from Loss = CP - SP.
First , Swap the sides of the equation :
⟶
Move SP to right hand side and change it's sign :
⟶
This is how , CP can be obtained when we are given loss and SP.
