Answer:
Step-by-step explanation:
Given.
Two points are given.
and
An exponential function is in the general form.
-------(1)
We know the points and
put the first point value in equation 1
--------(2)
put the second point value in equation 1
----------(3)
Put the a value from equation 2 to equation 3
Put the b value in equation 2
Put the a and b value in equation 1
So, the exponential function that passes through the points and are .
The equation of the line is and the equation of the circle is .
(a) Given: The given points are and .
To find: The parametric equation of line containing points and .
We know that the parametric equation of line containing and is given by where ∈.
Now,
i.e,
And,
Hence, the required parametric equation of the line is .
(b) Given: The radius of circle is 3 and centre is .
To find: The parametric equation of circle with radius 3 and centre .
We know that parametric equation of circle with radius and centre is given by where and .
So, the parametric equation of circle having radius 3 and centre is .
Hence, the required equation of the circle is .
i believe that the answer is 13/25
5
i dont see how you get 6 but it's 5
The correct answer is C. t= 8ln(100)
Hope this helped! :)
