<u>Answer:</u>

The correct answer option is B. f ( x ) = 0 . 2 5 ( 5 . 2 5 ) ^ x.

<u>Step-by-step explanation:</u>

If the numbers are positive along with the base of the exponent which must be greater than 1, then it an exponential growth function.

1. f(x)=6(0.25)^x:

Here the numbers are positive but the base of the exponent is 0.25 which is less than 1 so it is not an exponential growth function.

2. f ( x ) = 0 . 2 5 ( 5 . 2 5 ) ^ x:

Positive numbers with base of the exponent greater than 1, therefore it is an exponential growth function.

Answer: Second Option

f(x)=0.25(5.25)^x

Step-by-step explanation:

The exponential growth functions have the following form:

f(x) = a(b)^x

Where a is the main coefficient, b is the base and x is the exponent.

For this type of functions the base b must always be greater than 1. Otherwise it would be an exponential decay function

Among the options given, the only function whose base is greater than 1 is the second option:

f(x)=0.25(5.25)^x

Five and one half of 2 and one third is what number?
labwork [276]

Given:

Five and one half of 2 and one third.

To find:

The number for the given statement.

Solution:

Five and one half = 5\dfrac{1}{2}

2 and one third = 2\dfrac{1}{3}

The given statement is five and one half of 2 and one third.

Here, the word "of" is used for multiplication.

So, the expression for the given statement is:

5\dfrac{1}{2}\times 2\dfrac{1}{3}

=\dfrac{10+1}{2}\times \dfrac{6+1}{3}

=\dfrac{11}{2}\times \dfrac{7}{3}

=\dfrac{77}{6}

Therefore, the required number is \dfrac{77}{6}.

astraxan [27]

Solution:

we are given that

Don walked 3 3/5 miles on Friday

It can be re-written as

3\frac{3}{5}miles=\frac{18}{5}= 3.6miles

3 5/8 miles on sunday.

It can be re-written as

3\frac{5}{8}miles=\frac{29}{8}= 3.625miles

an d He walk 3.7 miles on satarday.

The distances from least to greatest is  3.6, 3.625, 3.7

or

The distances from least to greatest is  3\frac{3}{5}miles, 3\frac{5}{8}miles, 3.7 miles.
