lawyer [7]

Answer:

$C=10000(0.852)^t$

Step-by-step explanation:

Let the exponential function be,

$C=a(b)^t$

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),

$10000=a(b)^0$

a = 10000

For (8520, 1)

8520 = $10000(b)^1$

$b=\frac{8520}{10000}$

b = 0.8520

Therefore, exponential equation will be,

$C=10000(0.852)^t$

Pls answer 31 and 32. Show all your work.

Veronika [31]

31. diameter is twice radius. volume cylinder = πr²h
112π = π(7)²h
112π/(49π) = h
16/7 = h
32. volume of sphere is (4/3)πr³
if r = 1 the volume just = (4/3)π

both answers are C
