Answers

Answer 1

9514 1404 393

Answer:

  see attached

Step-by-step explanation:

Starting 3 feet from the motion detector, you will be at the point (0, 3) on the graph.

A normal walking speed is about 3 mph, or about 4.4 feet per second. So, walking slowly may be something less than 2 feet per second. In the attached graph, we show a walking speed of about 4 feet in 10 seconds, a really slow speed. Since you're walking away, the distance is increasing with time.

Step-by-step explanation:

Answer:

Step-by-step explanation:

1.  20 a yard and made 100. 100/20=5 yards

20x=100

2. Since they don't give the number of yards they did mow, this would be my answer. I would say half the amount. Since they cut their rates in half, they'll have to cut twice as many to even the amount as before. They would have to cut three - four times as many to make over the original amount. They only have one weekend, so that'll be hard.

Which equation can be represented by the graph?

Answers

Answer:

y+10 = -5(x-3)

Explaination:

Finding the slope intercept form provides you with the line your looking for

here you want to isolate y

y = -5(x-3)-10

and then ditrubute the -5 into the parenthesis

y = -5+15-10

Combine like terms

y = -5x +5

and by looking at this in terms on y=mx+b

the line will intercept the y-axis at (5,0) like the line above shows

The shape of an underground pool follows a parabola with the function LaTeX: f\left(x\right)=x^2+8xf ( x ) = x 2 + 8 x. What point represents the bottom of the pool? Group of answer choices

Answers

Answer:

The point that represents the bottom of the pool is [tex](x,y) = (-4, -16)[/tex].

Step-by-step explanation:

Given that the shape of the underground pool is a parabola, that is, a second order polynomial. Then, the point that represents the bottom of the pool is the vertex, which is contained in the standard form of the parabola. That is:

[tex]y-k = C\cdot (x-h)^{2}[/tex] (1)

Where:

[tex]x[/tex] - Independent variable, dimensionless.

[tex]y[/tex] - Dependent variable, dimensionless.

[tex]h[/tex], [tex]k[/tex] - Coordinates of the vertex, dimensionless.

[tex]C[/tex] - Constant, dimensionless.

The parabola is represented by [tex]f(x) = x^{2}+8\cdot x[/tex] and we proceed to transform into the desired form:

1) [tex]f(x) = x^{2}+8\cdot x[/tex] Given.

2) [tex]f(x) = (x^{2}+8\cdot x + 16)-16[/tex] Modulative property/Existence of the additive inverse.

3) [tex]f(x) +16 = (x+4)^{2}[/tex] Compatibility with the addition/Modulative property/Existence of the additive inverse/Perfect square trinomial.

4) [tex]y + 16 = (x+4)^{2}[/tex] Notation/Result.

Hence, the point that represents the bottom of the pool is [tex](x,y) = (-4, -16)[/tex].

y = 75x +1

is the correct answer hope it is helpful to you ☺️

The linear equation for this situation is,

⇒ y = 75x

And, There are 75 apple pick in one hour.

What is linear expression?

A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.

Given that;

The graph shows how many apples Erin can pick if she ,maintain a constant rate.

Now,

Let two points on the graph are (0, 0) and (1, 75).

So, Slope of the graph (m) = (75 - 0) / (1 - 0)

                                         = 75

Thus, The linear equation is;

⇒ y - y₁ = m (x - x₁)

⇒ y - 0 = 75 (x - 0)

⇒ y = 75x

Where, y is number of apples and x is number of hour.

Thus, Number of apple pick in one hour is;

⇒ y = 75 x 1

⇒ y = 75

So, There are 75 apple pick in one hour.

Therefore, The linear equation for this situation is,

⇒ y = 75x

And, There are 75 apple pick in one hour.
