X has to be inside the radical.
It would be

Which point is one the graph of f(x) = 2 * 5^x?

marusya05 [52]

Answer:

(0,2)

Step-by-step explanation:

I'm going to assume you meant Which point is ON the graph of f(x) = 2 * 5^x?

In order to do this question, all you need to do is pick any number as x. Lets pick 0 in this case.

f(x) = 2 * 5^x

f(0) = 2*5^0

= 2*1

= 2

So one point on the graph would be (0,2)

Why?

Because remember with functions, the f(x) can be swapped out with y, so when x = 0, y = 2.

garik1379 [7]

The number of the cupcakes sold that day that were vanilla flavored is 172.

<h3>How do we calculate a number from a percentage?</h3>

The number of the cupcakes sold that day that were vanilla flavored can be calculated using the following formula:

Number of vanilla flavored cupcakes sold = Total number of cupcakes sold * Percentage that were vanilla flavored .............. (1)

Substituting the relevant values into equation (1), we have:

Number of vanilla flavored cupcakes sold = 400 * 43% = 172

A circular disc has a circumference of 16pi meters. if we multiply the radius of the circular disc is by 10, what is the circumf

Flauer [41]

The circumference of the new disc 160Π that is 10 time of old circumference.

Step-by-step explanation:

Given,

Circumference of circular disc = 16Π (pi = Π)

Let, the radius of the circle be 'r'

Formula

The circumference of a circle with r radius = 2 Π r

According to the problem,

2 Π r = 16Π

or, 2r = 16 ( by eliminating the value of Π from both the side)

or, r = 8

Now, we multiply the radius by 10

so, the new radius is 8 X 10 = 80

Now the circumference = 2 Π X 80

= 160Π

Hence, the new circumference also will be 10 times of the older one.
