Answer:

Option 2 is correct.

Step-by-step explanation:

We have been provided a table of values of an exponential function and we are asked to find out the decay factor of the function.

Upon looking at our table we can see that every time x increases by one our y value remains one-third of the previous value.

To find out decay factor we will subtract 1/3 from 1.

$1-\frac{1}{3} =\frac{3-1}{3} =\frac{2}{3}$

Therefore, decay factor of the exponential function is $\frac{2}{3}$ and option 2 is correct choice.

weeeeeb [17]

Answer:

The correct answer is - 7.166 years

Step-by-step explanation:

Given:

principle amount: 3000

rate of interest: 2%

time?

Interent to get: 430

Formula:

I = P*t*r/100

here p = principle

I = interest

r = rate of intrest and t = time

Solution putting value and deriving Time as formula:

(3000*2*t)/100 = 430

t = 43000/3000*2

= 7.166 years.

He number of bats in a colony is growing exponentially. after 2 years, there were 220 bats. after 4 years, there were 880 bats.

dezoksy [38]

An exponential equation can be written from its description using the form

... y = (reference value)·((later value)/(reference value))^((t - (reference time))/(later time - reference time))

Here, we have

... reference value = 220; reference time = 2; later value = 880; later time = 4

so we can write the exponential equation as

... y = 220·(880/220)^((t-2)/(4-2)) = 220·4^(t/2 -1) = 55·2^t

Then for t=10, the expected number is

... y = 55·2^10 = 56,320

The surface of the Salton Sea in California is 226 feet below sea level. The peak of a mountain, also in California, is 10,000 f

Ivenika [448]

Answer:

10226 ft

Step-by-step explanation:

Let x be the sea level, A horizontal imaginary line on the sea's surface.

-Given that Salton is -226 ft below this line and the mountain is 10000ft above sea. The difference between this elevetions is calculated as;

$\bigtriangleup =Mountain \ Peak-Sea \ bottom\\\\=10000-(-226)\\\\=10000+226\\\\=10226$

Hence, the difference between the two elevations is 10226 ft
