Let price of ticket be x

Since all tickets cost same price,

50x = 70
Or, x=70/50
.•. x=1.4 $

So the school earns 1.4$ for 1 ticket.

Well I would say it’s $1.40 because if you do 70\50 you get 1.4 which is how much is the price for one ticket and to make sure just do 1.4 times 50

Wes works at a science lab that conducts experiments on bacteria. The population of the bacteria multiplies at a constant rate,

Dmitry [639]

Answer:

Correct answer: at 2 p.m. the population was 10,000

at 3 p.m. the population was 50,000

Step-by-step explanation:

At 1 p.m. population was 2,000

At 2 p.m. or after first hour, the population of bacteria increases

in this way 2,000 · k

At 3 p.m. or after second hour, the population of bacteria increases

2,000 · k²

At 4 p.m. or after third hour, the population of bacteria increases 2,000 · k³

2,000 · k³ = 250,000 => k³ = 250,000 / 2,000 = 125

k = ∛125 = 5 => k = 5

At 2 p.m. or after first hour, the population of bacteria was 2,000 · 5 = 10,000

At 3 p.m. or after second hour, the population of bacteria was 2,000 · 5² =

= 2,000 · 25 = 50,000

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)
