4.83 x 10^-3 can be re-written in standard form by moving the decimal point 3 units to the left: 0.00483.

Note: If you want to be mathematically correct, please write 10^(-3), not 10^-3. If the exponent is +, you don't need the parentheses.

Answer:

Checkmark:

✓ The sequence is geometric

✓ The recursive formula for the sequence is $An = A_{n-1}(-3)$ ; $A_{1} =-2$

✓ The explicit formula for the sequence is $t_{n} = (-2) (-3)^{n-1}$

Step-by-step explanation:

This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by -3 gives the next term.

r = -3

$t_{n} = t_{1} r^{n-1}$

$t_{1}$ = -2

Substitute the values in the equation:

$t_{n} = (-2) (-3)^{n-1}$

This is a explicit formula since the next value depends on the position of n (1, 2, 3 .etc)

The recursive formula would be:

$An = A_{n-1}(-3)$

-Twenty years ago, Mr. Davis purchased his home for $160,000. Since then, the value of the home has

pochemuha

The value of home today is $ 424527.63

Solution:

Given that, Twenty years ago, Mr. Davis purchased his home for $160,000

Since then, the value of the home has increased about 5% per year

To find: Exponential function to find the value of home today

The exponential growth function is given by:

$y = a(1 + r)^t$

Where, "y" is the worth after "t" years

"a" is the initial amount

"r" is the rate of interest per year

From given information,

a = 160000

t = 20 years

$r = 5 \% = \frac{5}{100} = 0.05$

Substituting the values we get,

$y = 160000(1 + 0.05)^{20}$

Thus the exponential function is found

Let us find the value

$y = 160000(1 + 0.05)^{20}\\\\y = 160000(1.05)^{20}\\\\y = 160000 \times 2.653\\\\y = 424527.63$

Thus the value of home today is $ 424527.63

Doreen lives 3/5 mile from the library. Sheila lives 1/3 as far away from the library as Doreen. How far does Sheila live from t

tankabanditka [31]

Answer:

She lives 1/5 miles away from the library

Step-by-step explanation:

Here, we want to get the distance that Sheila

lives from the library

From the question, we are told she lives 1/3 as far as Doreen

So what we have to do in this case is to simply multiply the distances

we have this as:

1/3 * 3/5 = 1/5
