There are 4 * 1/4 hr in one hour so we multiply yhe 3/4 by 4

Answer is 3/4 * 4 = 3 miles

A swim meet has 13 contestants signed up for the 100-meter butterfly event. The first heat has 6 swimmers. How many different wa

tino4ka555 [31]

Answer:

6 swimmers in the first heat can be arranged in 1716 different ways.

Step-by-step explanation:

A swim meet has 13 contestants signed up. To calculate the arrangement of first 6 swimmers in first heat we will use combinations because order doesn't matter.

So to select 6 swimmers out of 13 contestants number of different ways

= $^{13}C_{6}$

= $\frac{13!}{(6!)(13-6)!}$

= $\frac{13\times 12\times 11\times 10\times 9\times 8\times 7!}{6!\times 7!}$

= $\frac{13\times 12\times 11\times 10\times 9\times 8}{6\times 5\times 4\times 3\times 2\times 1}$

= $\frac{1235520}{720}$

= 1716

Therefore, 6 swimmers in the first heat can be arranged in 1716 different ways.

What is the domain of f(x)=-5x+4

ANTONII [103]

Answer:

f(x) = -5x + 4

Domain refers to the values of x that would result to a defined value of y. Since the given f(x) is a linear function, then all the values of x would give a corresponding value of y. So, the domain of f(x)=-5x+4 are all real numbers.

Or, plot the given equation to check.

The graph of f(x)=-5x+4 is shown below.

Since the graph is a straight line and can be extended continuously on both ends, this indicates that every values of x, there is a corresponding value of y.

Hence, the domain of the given function are all real numbers.Step-by-step explanation:
