Using the distance formula , find the distance from the center of your habitat to the point (x, y). Write this equation. Your an

alexdok [17]

Answer:

See explanation

Step-by-step explanation:

The distance formula is given by:

$d = \sqrt{ {(x_2-x_1)}^{2} + {(y_2-y_1)}^{2} }$

We want to find the distance between (a,b) and (x,y).

The center of the habitat is missing in the question.

Assuming the center is (a,b) where a and b are real numbers, then we can use the distance formula to obtain:

$d = \sqrt{(x - a)^{2} + {(y - b)}^{2} }$

For instance if the center of your habitat us (2,-1), then

$d = \sqrt{(x - 2)^{2} + {(y + 1)}^{2} }$

Cindy is buying a new car and wants to learn how the value of her car will change over time. Insurance actuaries predict the fut

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,

$C=10000(0.852)^t$
