Find the exponential function that passes through the points (2,80) and (5,5120)

juin [17]

Answer:

y = 5·4^x

Step-by-step explanation:

If you have two points, (x1, y1) and (x2, y2), whose relationship can be described by the exponential function ...

y = a·b^x

you can find the values of 'a' and 'b' as follows.

Substitute the given points:

y1 = a·b^(x1)

y2 = a·b^(x1)

Divide the second equation by the first:

y2/y1 = ((ab^(x2))/(ab^(x1)) = b^(x2 -x1)

Take the inverse power (root):

(y2/y1)^(1/(x2 -x1) = b

Use this value of 'b' to find 'a'. Here, we have solved the first equation for 'a'.

a = y1/(b^(x1))

In summary:

b = (y2/y1)^(1/(x2 -x1))
a = y1·b^(-x1)

For the problem at hand, (x1, y1) = (2, 80) and (x2, y2) = (5, 5120).

b = (5120/80)^(1/(5-2)) = ∛64 = 4

a = 80·4^(-2) = 80/16 = 5

The exponential function is ...

y = 5·4^x

What is the nearest ten thousand, the population of Vermont was estimated to be about 620,000 in 2008 . What might have been the

Degger [83]

Answer:

618,000 might be the exact population of Vermont in 2008

Step-by-step explanation:

* Lets explain the rule of rounding to the nearest ten thousands

- To round numbers to the nearest ten thousand, make the

numbers whose last four digits are 0001 through 4999 into the

next lower number that ends in 0000

- Ex: 83,525 rounded to the nearest ten thousand would be

80,000.

- Numbers that have the last four digits of 5000 or more should

be rounded up to the next even ten thousand

- Ex: The number 58,988 rounded to the nearest ten thousand

would be 60,000

* Lets do that in the problem

∵ The number is 620,000 after rounded to the nearest

ten thousands

∴ We can chose any number whose last four digits are 00001

through 4999 as 624,000 OR 5000 or more as 618,000

∴ 618,000 might be the exact population of Vermont in 2008

A tree is growing on a hill. In an attempt to make the tree grow straight up, a 12-foot-long wire is attached to a tree at a poi

melisa1 [442]

For this case what we must do is use the law of cosines.
We have then:
12 ^ 2 = 6 ^ 2 + 10 ^ 2 - 2 * (6) * (10) cos (x)
Clearing we have:
cos (x) = (12 ^ 2- (6 ^ 2 + 10 ^ 2)) / (- 2 * (6) * (10))
x = acos ((12 ^ 2- (6 ^ 2 + 10 ^ 2)) / (- 2 * (6) * (10)))
x = 93.82 degrees
Answer:
The tree is growing in relation to the hill at:
x = 93.82 degrees
