Answer:
f(2) = f(3) = 102 ft
Step-by-step explanation:
The height f at t = 2 seconds is given by:
The height f at t = 3 seconds is given by:
For both t =2 and t =3, the expression results in a height of 102 ft, therefore f(2) = f(3) = 102 ft.
Answer:
The perimeter or circumference of a half mirror = 37.68 cm
Step-by-step explanation:
- The diameter of circular measure = 24 cm
We know that the perimeter of a circular shape is called the 'circumference', with the formula
- Circumference of a circle = C = 2πr
When the mirror is cut into half, the diameter gets half as well.
- Thus, the diameter of a half mirror = 24/2 = 12 cm
We know that radius = r = diameter / 2 = 12/2 = 6 cm
Thus, the perimeter of half of the mirror = C = 2πr
= 2(3.14)6
= 37.68 cm
Therefore, the perimeter or circumference of a half mirror = 37.68 cm

<span>Answer:
The linear approximation, about x= 0, is as you said, s(x)= s(0)+ s'(0)(x- 0)= 60- x. From that, what is s(51)?
These are some things that I have been trying:
x = 51
a = 0
s(0) = 60
s'(0) = -0.292184076
How in the world did you get this? This appears to be your main error. You said, above, that s'(t)= \frac{-3600}{(60+ x)^2}, Setting x= 0 in that gives, as I said before, -1.
s(0) + s'(0)(51 - 0) = 60 - 14.90138787 = 45.098 ...
And,
x = 0
a = 51
s(0) = 60
s'(0) = -0.292184076
s(0) + s'(0)(0 - 51) = 60 + 14.90138788 = 74.901 ...
It's probably something to do with how I am substituting the values but I haven't been able to arrange them in a way that yields anything close to the answer. I did find something that gave me an answer of 9 when I was playing around with the x - a stuff but I cannot remember what it was that I did. Maybe I need to add the answer of 9 that I found to the s(a) = 60 in order to get 69?</span>
