Answer:

So it will take the stone 1 (one) second to reach its maximum height.

Step-by-step explanation:

Notice that the mathematical quadratic expression given is that of a parabola with branches pointing down. This means that the maximum value for that parabola is at the vertex. Your expression is also given in vertex form:

f(x)=a\,(x-x_v)^2+y_v

where the pair of coordinates (x_v,y_v) are the x coordinate of the vertex and the y coordinate of the vertex.

Since x in your case is the time the stone is on the air, then the maximum (vertex) is at the point (1, 45) where "1" is the time in seconds and 45 is the height of the stone in meters.

So it will take the stone 1 (one) second to reach its maximum height.

Graph the inequality.<br> -6 ≤y + 2x &lt; 15
omeli [17]

Inequalities help us to compare two unequal expressions. The correct option is B.

<h3>What are inequalities?</h3>

Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed. It is mostly denoted by the symbol <, >, ≤, and ≥.


The given inequality -6 ≤y + 2x < 15 can be broken into two small inequality, as shown below.

  • -6 ≤y + 2x
  • y + 2x < 15

Now, if we plot the inequality as shown below, then the area in which both the shaded region overlap is the area of the this inequality.

Hence, the correct option is B.

Bobby is working in a lab testing bacteria populations. After starting out with a population of 282 bacteria, he observes the ch
pickupchik [31]

Given that the population quadruples every 39 minutes, you can determine that this bacteria population has Exponential Growth.

By definition, an Exponential Equation as this form:

y=ab^t

Where "a" is the initial amount, "b" is the base, and "t" is the time period.

In this case, you know that:

\begin{gathered} a=282 \\ b=4 \\ y=P \end{gathered}

Therefore, since you need to express the time "t" in minutes:

t=\frac{t}{39}

Now you can write the following equation to model the situation:

P=282\cdot4^{\frac{t}{39}}
