Answer:
A = 24 cm^2
Step-by-step explanation:
The area of a triangle is
A = 1/2 bh
A = 1/2 (6)*8
A = 24 cm^2
Answer:
a is answer correct i think
Step-by-step explanation:
Answer:
middle one, it is he line of best fit
Let's plug the values and see which couple satisfy the equation: since 
, if we plug the values from the first option 
we have
which is correct.
If we plug the values from the second option 
we have
which is not correct
If we plug the values from the third option 
we have
which is not correct
If we plug the values from the fourth option 
we have
which is not correct
So, the answer is the first one.
Answer:
87,000 ; 10.6%
Step-by-step explanation:
Given the function :
P(t)=87,000e^0.106t
P(t) is an exponential function ; comparing the given function to the general form of an exponential function :
y = Ae^rt
Where,
A = initial amount ; r = growth rate ; t = time
The Given function models t years after 2010, that is the 2010 population is the initial population of the city.
Comparing the general exponential equation with the function given:
A = 87,000 = population of city in 2010
The growth rate :
rt from the general equation compares to 0.106t in the given function.
rt = 0.106t
r = 0.106
Hence, the rate of change = 0.106 * 100% = 10.6%
