Hello!


The graph, (2/5)^x is an exponential function.


Since there is not a negative symbol in the front of the function, options A and B are incorrect.


For option 3 to be correct, there would need to be a negative symbol in front of the exponent, x.


So therefore, the answer option 4. (Also, I'll post a graph. :))

Agata [3.3K]

Answer:

Total Cost for Pretzels and juice is $9.

Step-by-step explanation:

Given:

Number of Bags of pretzels =3

Cost for each bag = $2.00

Total Cost of Pretzels is equal to product of Number of Bags of pretzels and Cost for each bag.

Framing in equation form we get;

Total Cost of Pretzels = 3\times 2= \$6

Also Given:

Number of Bottle of Juice = 2

Price of each bottle = $1.5

Total Cost of Juice is equal to product of Number of Bottle of Juice and Price of each bottle.

Framing in equation form we get;

Total Cost of Juice = 2\times 1.5= \$3

Total Cost of Pretzels and juice is equal to sum of Total Cost of Pretzels and Total Cost of Juice.

Total Cost of Pretzels and juice = Total Cost of Pretzels + Total Cost of Juice

Total Cost of Pretzels and juice = $6 + $3 =$9

Hence Total Cost for Pretzels and juice is $9.

The formula for the volume
MakcuM [25]

Answer:

\sqrt{  \frac{{3V\pi } }{h} = r

Step-by-step explanation:

V = 1/3 pi r^(2) *h

Rewrite:

V = pi * r^(2) * h/3

Inverse operations:

V / h / 3 = pi * r^2

Simplify:

3V/h = pi * r^2

Inverse operations:

3V/h / pi = r^2

Simplify:

3Vpi/ h = r^2

Inverse operations:

sqrt( 3Vpi/h) = r

\sqrt{  \frac{{3V\pi } }{h} = r
