Answer:

A. 47, 62, 72.

Step-by-step explanation:

Let A = first game

Let B = second game

Let C = third game

<u>Given the following data;</u>

Total score = 180 points

If A = 47 points;

To the nearest ten, A = 50

If B = 62 points;

To the nearest ten, B = 60

If C = 72 points;

To the nearest ten, C = 70

Total points = A + B + C

Substituting into the equation, we have

Total points = 50 + 60 + 70

Total points = 180 points.

<em>Therefore, 47, 62 and 72 when rounded to the nearest 10, most likely represents the actual scores (180) of the three games.</em>

A mine elevator was at a depth of -120 feet. After 15 seconds, the mine elevator was at a depth of -30 feet. What expression can
Dafna11 [192]

Answer:

The answers to the given question are:

i.  The equipment elevator is at a depth of 176 feet (-176 feet), while the miner's elevator is at a depth of 210 feet (-210 feet) below the surface.

ii. The miner's elevator is deeper than that of the equipment.

The speed of an object is the rate at which the object moves.

i.e. speed =

Thus,

Speed of the equipment elevator = 4 feet per second

Speed of the miner's elevator = 15 feet per second.

Time of descent of the equipment elevator = 30 + 14

                                 = 44 seconds

So that, the distance of the elevator at this time is;

speed =

⇒ distance = speed x time

                  = 4 x 44

                  = 176

  distance = - 176 feet

The distance of the miner's elevator after 14 seconds is:

speed =

⇒ distance = speed x time

                 = 15 x 14

                 = 210

 distance = - 210 feet

Thus, after another 14 seconds, the equipment elevator is at a depth of 176 feet (-176 feet), while the miner's elevator is at a depth of 210 feet (-210 feet) below the surface.

Therefore, the miner's elevator is deeper than that of the equipment.

between 1995 and 2006, the population of samburg, usa(in thousands) can be modeled by f(x) = 0.35x(squared) - 2.1x+15.8 where x=
Juli2301 [7.4K]
\bf f(x)=0.35x^2-2.1x+15.8\qquad &#10;\begin{cases}&#10;x=\textit{year since 1995}\\&#10;f(x)=\textit{population amount}&#10;\end{cases}

the equation is a quadratic one, and it has a positive coefficient on the leading term, meaning, is opening upwards, so it has a "burrow" for the vertex.

the minimum or lowest point for a quadratic opening upwards is, well, the vertex point :),   the "x" value is the year, the "y" or f(x) value is the population, we're asked for the year, or the x-coordinate of the vertex

well   \bf \begin{array}{llll}&#10;f(x)=&0.35x^2&-2.1x&+15.8\\&#10;&\quad \uparrow &\quad \uparrow&\uparrow \\&#10;&\quad  a&\quad  b &c&#10;\end{array}&#10;\\\\&#10;&#10;\\\\&#10;\qquad  \textit{vertex of a parabola}\\ \quad \\&#10;\qquad &#10;&#10;\left(\boxed{-\cfrac{{{ b}}}{2{{ a}}}}\quad ,\quad  {{ c}}-\cfrac{{{ b}}^2}{4{{ a}}}\right)

A function that models the profit for a new pet-monitoring system shows that there is no profit made until the price reaches $95
-Dominant- [34]

The profits at x = $185 is 0 and the graph is attached below:

<h3>What is graph?</h3>

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

Function is to model the profits of a new pet-monitoring system, so, if the profits are y and x then y = f(x)

The curve shows that y is negative at values of x< $95, then the profits increase when x varies between $95 and $140.

The profits reach a maximum at $140 and then the profits start to reduce as x increases again.

So, the profits at x = $185 is 0.
