Answer:

r=41/2

Step-by-step explanation:

You have to divide the diameter,  41, by 2 because the radius of the circle is half of the diameter. So, the answer would be 20.5

Answer:

Step-by-step explanation:

                                                                41 cm

Recall that d = 2r.  Here, r = d/2, or r = -------------

                                                                     2

The height of josie’s dog 11 1/4 inches to the nearest quarter inch and 11 inches to the nearest half inch.which measurement is
Lisa [10]
Both measurements are correct if you're rounding the dogs height.

But the more precise measurement would be 11 1/4.

Mainly because its a smaller fraction so it has more meaning to it instead of just plain 11

It would get more precise as the fraction got larger
For example.

Not very precise 
11, 11 1/2, 11 1/4,   

Precise
11 1/8, 11 1/16 

Hope this helps!

Kyle ran 2/3 mi on Monday,1 1/6 mi on Tuesday, and 7/12 mi on Wednesday.
BartSMP [9]

you would change the denominators to the least common multiple, in this case, 12. then you would change the fractions to 8/12, 14/12, and 7/12. you would add those, and get 29/12. divide 29 by 12, and get 2. add the rest to get 2 5/12.

Show all work to identify the asymptotes and end behavior of the function f(x)= 5x/x-25.
jeyben [28]

Considering the given function and the asymptote concept, we have that:

  • The vertical asymptote is of x = 25.
  • The horizontal asymptote is of y = 5.
  • The end behavior is that as x \rightarrow \infty, f(x) \rightarrow 5.

<h3>What are the asymptotes of a function f(x)?</h3>

  • The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator.
  • The horizontal asymptote is the value of f(x) as x goes to infinity, as long as this value is different of infinity. Hence it also gives the end behavior of the function.

In this problem, the function is:

f(x) = \frac{5x}{x - 25}.

The vertical asymptote is found as follows:

x - 25 = 0 -> x = 25.

The horizontal asymptote is found as follows:

y = \lim_{x \rightarrow \infty} f(x) = \lim_{x \rightarrow \infty} \frac{5x}{x - 25} = \lim_{x \rightarrow \infty} \frac{5x}{x} = \lim_{x \rightarrow \infty} 5 = 5.

Hence the end behavior is that as x \rightarrow \infty, f(x) \rightarrow 5.
