Answer:

The formula that relates circumference and radius is $C=2\pi r$ .

Step-by-step explanation:

The circumference of a circle is calculated by the formula

$C=2\pi r$

Where,

C is circumference of the circle.

r is radius of the circle.

π is 22/7 or 3.14.

In the given options π is not missing. So, all the given options are incorrect.

Therefore the formula that relates circumference and radius is $C=2\pi r$ .

Which of the following demonstrates how the 20 is calculated using the<br> combination pattern?

ZanzabumX [31]

Answer:

Step-by-step explanation:

The diagram shows Pascal's triangle. Pascal's triangle is a triangular array of the binomial coefficients.

The entry in the $n^{th}$ row (start counting rows from 0) and $k^{th}$ column (start counting columns from 0) of Pascal's triangle is denoted by

$C^n_k=\left(\begin{array}{c}n\\ k\end{array}\right)$

Coefficient 20 stands in 6th row, then n = 6 and in 3rd column, so k = 3.

Hence,

$20=C^6_3=\left(\begin{array}{c}6\\ 3\end{array}\right)=\dfrac{6!}{3!(6-3)!}$

Answer:

f(x) is the total cost and x is the number of peaches.

Step-by-step explanation:

We know that each peach costs $0.75. This means the expression 0.75x represents the total cost of peaches; this makes x represent the number of peaches.

We also know that $2.25 is the cost of juice. Adding it to the cost of peaches gives us the total cost; this means f(x) represents the total cost.
