Answer:
f(4) for the function 
is 
Step-by-step explanation:
We need to find f(4) for the function
For finding f(4) we will put x= 4 in the given function
Put x = 4
SO, f(4) for the function is

if means not true but what if it was a question like that or a thing you ask your friends
Answer:
7.
lateral surface area of traingular prism=perimeter of traingle ×length=[5+3+4]×6=72cm²
curved surface area=2[area oftraingle]=2×1/2×4×3
=12cm²
now
total surface area=72cm²+12cm²=84cm²
8.
volume of traingular prism=area of traingle ×length
=1/2×12×3.4×4=81.6cm³
Answer:
√89
Step-by-step explanation:
√(4+4)2+(0-5)2
√(8)2+(-5)2
√64+25
√89
Answer:
Exponential function.
Step-by-step explanation:
We have been given that the number of visitors to the Eiffel tower in Paris increase by 1.5% each year.
Since linear function changes at a constant rate and exponential function changes at a rate that's always proportional to the value of the function.
We can see that number of visitors is not changing at a constant rate. We can see that each next year number of visitors increased by 1.5%, so number of visitors is increasing exponentially.
Therefore, exponential function best models the relationship between time and the number of visitors to the Eiffel Tower.
