Answer:
![C=10000(0.852)^t](https://tex.z-dn.net/?f=C%3D10000%280.852%29%5Et)
Step-by-step explanation:
Let the exponential function be,
![C=a(b)^t](https://tex.z-dn.net/?f=C%3Da%28b%29%5Et)
Here, C = cost of the car
t = Duration or period in years
From the given table,
Two points representing cost of the car and time are (10000, 0) and (8520, 1),
For (10000, 0),
![10000=a(b)^0](https://tex.z-dn.net/?f=10000%3Da%28b%29%5E0)
a = 10000
For (8520, 1)
8520 = ![10000(b)^1](https://tex.z-dn.net/?f=10000%28b%29%5E1)
![b=\frac{8520}{10000}](https://tex.z-dn.net/?f=b%3D%5Cfrac%7B8520%7D%7B10000%7D)
b = 0.8520
Therefore, exponential equation will be,
![C=10000(0.852)^t](https://tex.z-dn.net/?f=C%3D10000%280.852%29%5Et)
Answer:
The radius of the circle is 12.006 m.
Step-by-step explanation:
Let us assume the radius of the circle = r
Circumference = 75.4 m
Now, CIRCUMFERENCE OF A CIRCLE = 2 π r
⇒ 75 .4 m = 2 π r
Now, putting π = 3.14, we get:
75 .4 m = 2 (3.14) r
⇒ 75.4 = 6. 28 r
or, r = 75.4/6.28 = 12.006
or, r = 12.006 m
Hence, the radius of the circle with circumference 75.4 m is 12.006 m.
