Is f(x)=3x5^2x-3 an exponential function? If so, write it in the form f(x)=ab^x

Anna11 [10]

Answer:

$f(x)=\frac{3}{125} * 25^x$

Step-by-step explanation:

Given

$f(x)=3*5^{2x-3}$

Required

To determine if it is an exponential function, we have to write in form of

$f(x) = ab^x$

If we're able to do so, then the function is an exponential function.

If otherwise, then it is not

$f(x)=3*5^{2x-3}$

Apply Law of indices

$f(x)=3*\frac{5^{2x}}{5^3}$

Express 5^3 as 125

$f(x)=3*\frac{5^{2x}}{125}$

Factorize the exponent of 5

$f(x)=3*\frac{5^{(2)x}}{125}$

Express 5^2 as 25

$f(x)=3*\frac{25^x}{125}$

This can be rewritten as:

$f(x)=\frac{3}{125} * 25^x$

By comparing the above to $f(x) = ab^x$

We have that

$a = \frac{3}{125}$

$b^x = 25^x$

Since, we've be able to express the function as $f(x) = ab^x$

Then, $f(x)=3*5^{2x-3}$ is an exponential function

Two baskets contain snacks. The basket contain 12 bags of peanuts, of which 5 are reduced sodium and 8 granola bars, of which 2

Ghella [55]

There are a total of 20 snacks in each bag. We consider the probability of picking a bag of peanuts with reduced sodium and then a granola bar with reduced sodium, then multiply by 2 (because we could pick them in the other order).

There is a 5/20 chance of picking a sodium-reduced bag of peanuts first, and a 2/20 chance of picking a sodium-reduced granola bar next. Thus, the chance of picking them together in that order is 5/20*2/20=10/400, or 1/40. Because we could pick the snacks in either order, we multiply by two, for a result of a 1/20 probability.
