M is the midpoint of RS. R has coordinates (-2,-3) and M has coordinates (1,0). Find the coordinates of S.

Marta_Voda [28]

Answer:

$(4,3)$

Step-by-step explanation:

Given

$R = (-2,-3)$

$M = (1,0)$

Required

Determine the coordinates of S

Midpoint is calculated as:

$M(x,y) = \frac{1}{2}(x_1 +x_2,y_1+y_2)$

Where:

$(x,y) = (1,0)$

$(x_1,y_1) = (-2,-3)$

Substitute these values in the above formula:

$(1,0) = \frac{1}{2}(-2 + x_2,-3+y_2)$

Multiply through by 2

$2 * (1,0) = 2 * \frac{1}{2}(-2 + x_2,-3+y_2)$

$(2,0) = (-2 + x_2,-3+y_2)$

By direct comparison:

$2 = -2 + x_2$ and $0 = -3 + y_2$

Solving for x2

$2 = -2 + x_2$

$x_2 = 2 + 2$

$x_2 = 4$

Solving for y2

$0 = -3 + y_2$

$y_2 = 0 + 3$

$y_2 = 3$

Hence, the coordinates of S is: $(4,3)$

The graph shows the distance in miles of a runner over x hours. What is the average rate of speed over the interval [9, 11]?

ELEN [110]

Question:

The graph shows the distance in miles of a runner over x hours. What is the average rate of speed over the interval [9, 11]?

A. 2/5

B. 1

C.2

D.5/2

The image of the graph is attached below.

Answer:

Option D: 5/2 is the average speed over the interval [9,11]

Explanation:

The graph shows the distance in miles of a runner over x hours.

Now, we need to determine the average rate of speed over the interval $[9,11]$

The x-axis represents the time taken.

The y-axis represents the distance.

To find the average speed, let us use the formula for speed which is given by

$speed=\frac{distance}{time}$

Thus, substituting the coordinates $(9,6)$ and $(11,11)$ , we have,

$speed=\frac{11-6}{11-9} =\frac{5}{2}$

Hence, the average speed over the interval $[9,11]$ is $\frac{5}{2}$
