Answer:
15
Step-by-step explanation:
sqrt230=15.165...
(0,5.25)(10,13.75)
slope(m) = (y2 - y1) / (x2 - x1)
slope(m) = (13.75 - 5.25) / (10 - 0) = 8.5/10 = 0.85
y = mx + b
(0,5.25)...x = 0 and y = 5.25
slope(m) = 0.85
now we sub, we r looking for b, the y int
5.25 = 0.85(0) + b
5.25 = b
so ur equation is : y = 0.85x + 5.25 or C(t) = 0.85t + 5.25 <==
cost of a 12 min taxi ride.....sub in 12 for t
C(t) = 0.85t + 5.25
C(12) = 0.85(12) +5.25
C(12) = 10.20 + 5.25 = 15.45
so a 12 min ride would cost u : $ 15.45 <==
It’s True.. you take the “extreme” variable from each proportion and cross multiply them before setting them equal to the product of the two “means” (which are just the other 2 numbers in the proportions).
Answer:
--- function
The monthly rate is 10%
Step-by-step explanation:
Given
Let

So, we have:
--- Monday
--- One month later
Required
The function
The function is represented as:
In
, we have:




In
, we have:


Substitute: 

Solve for b


So, the function is:


To calculate the monthly rate (r), we have:

Compare to: 

Make r the subject

Substitute 


Express as percentage
