Find the midpoint of the line segment whose endpoints are given (3/5 , -6/7),(2/5,5/7)

snow_lady [41]

The formula of a midpoint between E and F:

$M_{EF}\left(\dfrac{x_E+x_F}{2};\ \dfrac{y_E+y_F}{2}\right)$

We have the points $\left(\dfrac{3}{5},\ -\dfrac{6}{7}\right)$ and $\left(\dfrac{2}{5},\ \dfrac{5}{7}\right)$ . Substitute:

$\dfrac{\frac{3}{5}+\frac{2}{5}}{2}=\dfrac{\frac{5}{5}}{2}=\dfrac{1}{2}\\\\\dfrac{-\frac{6}{7}+\frac{5}{7}}{2}=\dfrac{-\frac{1}{7}}{2}=-\dfrac{1}{7}\cdot\dfrac{1}{2}=-\dfrac{1}{14}$

Answer: $\boxed{\left(\dfrac{1}{2},\ -\dfrac{1}{14}\right)}$

Answer:

Explanation:

According to the Unit Circle, sin π\6 is ½, so we plug this into the cosine function to get this:

cos π\6 - π\6 → cos 0 >> 1

** I do not have Unit Circle video uploaded yet, but if I need to, just notify me in the comments or on of course, You-Tube.

*** Plus, we need to make sure that the x-value falls in between 0 and π\2, which it did, so no need to worry.

The ABC Toy Company is creating two similar pieces for a board game, as shown below. How could the toy maker confirm that the pi

kati45 [8]

Answer:

The company can confirm that the pieces are similar by verifying that the relationship between the sides of the parts in the drawing created with MS Visio, of the diagram in a similar question found online, are;

$\dfrac{\overline {RS}}{\overline {XZ}} = \dfrac{\overline {RT}}{\overline {XY}} = \dfrac{\overline {ST}}{\overline {ZY}}$

Step-by-step explanation:

The definition of similarity is the quality of two or more objects having a common definitive property

Two objects in Euclidean geometry are similar if they are similar in shape and parameters of one shape can be obtained from the other by the application of a uniform scale and/or translation, reflection and rotation

The ABC toy maker could confirm that the pieces are similar by verifying that the corresponding sides of the two shapes have a common ratio
