Question:

Lisa walks at an average speed of  6 km/h for 15 hours.

Dan completes the same distance in  an hour.  Calculate Dan's average speed.​

Answer:

[tex]Speed = 90km/hr[/tex]

Step-by-step explanation:

Given

Lisa:

[tex]Speed = 6km/hr[/tex]

[tex]Time = 15\ hr[/tex]

First, we calculate the distance covered by Lisa:

[tex]Distance = Speed * Time[/tex]

[tex]Distance = 6km/hr * 15\ hr[/tex]

[tex]Distance = 90km[/tex]

So, Dan distance can be represented as:

[tex]Distance = 90km[/tex] --- Dan completes the same distance as Lisa

[tex]Time = 1\ hr[/tex] -- Time to complete the distance

Dan's average speed is:

[tex]Speed = \frac{Distance}{Time}[/tex]

[tex]Speed = \frac{90km}{1\ hr}[/tex]

[tex]Speed = 90km/hr[/tex]

Hence, Dan's average speed is 90km/hr

The correct sequence of transformations takes A to its image A' is,

⇒ A translation 1 unit down followed by a reflection in the x-axis.

A transformation that occurs when a figure is moved from one location to another location without changing its size or shape is called translation.

We have to given that;

The sequence of transformations takes A to its image A'.

Now, We have;

The coordinate of A are (4, 5)

And, The coordinate of A' are (4, - 4)

Hence, The correct sequence of transformations takes A to its image A' is,

⇒ A translation 1 unit down followed by a reflection in the x-axis.

Answer:

The answer is below

Step-by-step explanation:

Acceleration is the time rate of change in velocity. Acceleration is given by:

Acceleration = change in velocity / time taken

Acceleration = (final velocity - initial velocity) / time

1) The Ferrari is from rest, hence initial velocity = 0. The final velocity = 100 km/h = [tex]\frac{100\ km*1000\ \frac{m}{km} }{1\ hr*\frac{3600\ s}{1\ hr} } =27.78\ m/s[/tex], time = 5 s

Acceleration = (0 - 27.78) / 5 = 5.56 m/s²

2) The car has initial velocity = 10 m/s. The final velocity = 10 m/s since velocity is constant. time = 20 s

Acceleration = (10 - 10) / 20 = 0 m/s²

3) The ball has initial velocity = 12 m/s. The final velocity = 0 m/s since it stops. time = 36 s

Acceleration = (0 - 12) / 36 = -0.33 m/s²

Answer:

Y=2x-2

Step-by-step explanation:

Slope intercept form is also known as y=mx+b

The slope of a line is rise over run. In this case that would be 2/1 which simplifies to 2

The intercept is where the line crosses the y axis, which is at -2

So your equation would be y=2x-2

Step-by-step explanation:

Answer:

(D): (-1,-6)

Step-by-step explanation:

Given

[tex](x_1,y_1) = (-2,-5)[/tex]

[tex]m = -1[/tex]

Required

Find [tex](x_2,y_2)[/tex]

Slope (m) is calculated using:

[tex]m = \frac{y_2 -y_1}{x_2 - x_1}[/tex]

Substitute values for m, x1 and x2

[tex]-1 = \frac{y_2 -(-5)}{x_2 - (-2)}[/tex]

[tex]-1 = \frac{y_2 +5}{x_2 +2}[/tex]

Cross Multiply:

[tex]-1(x_2 +2) = y_2 +5[/tex]

[tex]-x_2 -2 = y_2 +5[/tex]

Make y the subject

[tex]y_2 = -x_2 - 2 - 5[/tex]

[tex]y_2 = -x_2 - 7[/tex]

Only (D): (-1,-6) satisfy this condition:

Substitute -1 for x2 and -6 for y2.

[tex]-6 = -(-1) - 7[/tex]

[tex]-6 = 1- 7[/tex]

[tex]-6 =- 6[/tex]

Hence:

(D): (-1,-6) is true
