Answer:

Step-by-step explanation

Vertex (-3,-6)

to find y intercept, let x = 0

y = (0) + 6(0) + 3

y =3

y intercept (0,3)

If x is negative then the graph is upside down, so in this case its open up

Butoxors [25]

In this experiment, there is an independent variable that is the time spent playing video games.

<h3>What is an independent variable?</h3>

In research there are different ways to test a hypothesis. One of them is the experiments in which we have one or more factors that can be modified to alter the result.

These factors are known as independent variables because their variation does not depend on other factors. On the contrary, they influence the variation of other factors that are known as dependent variables.

According to the above, it can be inferred that time is the independent variable of this research because its modification is planned to evaluate the different variables that it can cause.

Can you guys pls help me with this math question

Answer:

Dimensions:  125 m x 250 m

Area:  31,250 m²

Step-by-step explanation:

Given information:

  • Total amount of fencing = 500m
  • Only 3 sides of the land need to be fenced

First, let us assume that the land is <u>rectangular</u> in shape.

Let y = length of the side opposite the river

Let x = length of the other 2 sides of the land

Therefore, we can create two equations from the given information:

  <u>Area of land</u>:   A= xy

  <u>Perimeter of fence</u>:   2x + y = 500

Rearrange the equation for the perimeter of the fence to make y the subject:

\begin{aligned} \implies 2x + y & = 500\\ y & = 500-2x \end{aligned}

Substitute this into the equation for Area:

\begin{aligned}\implies A & = xy\\& = x(500-2x)\\& = 500x-2x^2 \end{aligned}

To find the value of x that will make the area a <em>maximum</em>, <u>differentiate</u> A with respect to x:

\begin{aligned}A & =500x-2x^2\\\implies \dfrac{dA}{dx}& =500-4x\end{aligned}

Set it to zero and solve for x:

\begin{aligned}\dfrac{dA}{dx} & =0\\ \implies 500-4x & =0 \\ x & = 125 \end{aligned}

Substitute the found value of x into the original equation for the perimeter and solve for y:

\begin{aligned}2x + y & = 500\\\implies 2(125)+y & = 500\\250+y & = 500\\y & = 250\end{aligned}

Therefore, the dimensions that will give Christine the maximum area are:

125 m x 250 m (where 250 m is the side opposite the river)

The maximum area is:

\begin{aligned}\implies \sf Area_{max} & = xy\\& = 125 \cdot  250\\& = 31250\: \sf m^2 \end{aligned}
