Answer:
Step-by-step explanation:
Given
Fireplace is in the form of semi-ellipse with height of 3 ft from center
Length of base=8 ft
if the arch is in the form of ellipse then it can be considered as horizontal ellipse with 2 a and 2 b be length of major and minor axis
2 a =8
a=4 ft
If contractor cover the whole base
then total length of string=2a =8 ft
(b)String should be nailed at focus
focus of ellipse is a e
where e=eccentricity
Focus
Thus string should be nailed at 2.64 m from center
Answer:
It is an exponential function.
Initial value is - 1.8 and the base is 6.
Step-by-step explanation:
The function is given by and it is an exponential function as the general form of an exponential function is
.
Here, if we put x = 0, the function becomes .
Therefore, the initial value of the function is - 1.8.
In the general equation of exponential function , b is called the base and x is the exponent.
Therefore, in our case the base of the function is 6. (Answer)
