Answers: 
<u>Question 19:</u> 177 bpm
<u>Question 20:</u> 95˚F

Explanations:
<u>Question 19:</u>
You had the formula set up properly like this:
R =  \frac{885 \sqrt{25} }{25}  =  \frac{885(5)}{25}  =  \frac{4425}{25} 
This is where you went wrong - I don't know exactly what you did, but your division of 4425 ÷ 25 is wrong. You should have ended up with 177 which is the correct answer. 
<u>Question 20:</u>
You had the formula set up correctly again, and merely used the wrong sign when adding 32. 
F =  \frac{9(35)}{5} + 32 =  \frac{315}{5} + 32
This is where you went wrong. You subtracted 32 from 63 when you should have added it. (See red circle on your subtraction.)
63 + 32 = 95˚F

The function f(x) = (x - 4)(x - 2) is shown below. What is true about the domain and range of the function?​
Arlecino [84]

Answer:

Dom\{f(x)\} = \mathbb{R} (Since polinomial functions are continuous)

Ran\{f(x)\} = [-1, +\infty) (As this quadratic function has an absolute minimum, represented by its vertex)

Step-by-step explanation:

Graphically speaking, quadratic functions are represented by parabolas. In this case, we have a parabola in factorized form. From Theory of Functions, we get that domains of function represents the set of values of x so that exist an image, whose set is known as range is represented by values of f(x).

x is represented by horizontal axis in the figure, whereas f(x) is represented by the vertical axis. By using this approach we get that domain and range of the function are, respectively:

Dom\{f(x)\} = \mathbb{R} (Since polinomial functions are continuous)

Ran\{f(x)\} = [-1, +\infty) (As this quadratic function has an absolute minimum, represented by its vertex)
