He needs 160 5-star reviews in a role. We can write a function to solve this problem. His current total stars is 4.4*160=704. Suppose he needs x more 5-star reviews, then his total stars will be 704+5x. 160+x is the new number of reviews, and the new average will be 4.7, so 4.7*(160+x)=704+5x. The solution is 160. Besides, if you want to get the answer really fast, you can see that 4.7 is right in the middle of 4.4 and 5, so you can immediately guess that the number of new 5-star reviews should be equal to the number of current reviews.

The statement that describes a key feature of function g if g(x) = f(x + 4) is C. horizontal asymptote of y = 0.

<h3>What is a function?</h3>

It should be noted that a function is an expression that shows the relationship between the variables.

In this case, the statement that describes a key feature of function g if g(x) = f(x + 4) is that the horizontal asymptote of y = 0.

The horizontal asymptote is vital for guiding the variables

Is 0.2487 a interger
BabaBlast [244]

No.  0.2487 is not an interger.

There are two big reasons for this:

1).  There is no such thing as an ' interger ',
       so no number could be one.
       You probably mean ' integer '.

2).  An integer is a whole number ... a number
      with no fraction part and no decimal part.
      0.2847  is all decimal, and not even big enough
      to make the smallest whole number.  (That's ' 1 '.)

MAXImum [283]

Answer:

280 m

Step-by-step explanation:

a² + b² = c²

450² + b² = 530²

202,500 + b² = 280,900

280,900 - 202,500 = 78,400

√78,400 = 280
