Answer:
Eric has read 13/18 more of the book than James.
Step-by-step explanation:
James has read 18 pages of a book and Eric has read 13 pages of a book.
Answer:
see explanation
Step-by-step explanation:
Since Θ is an angle in the third quadrant, then secΘ < 0 and tanΘ > 0
Using the identity
sec x =
, then
cos x = - ![\sqrt{1-sin^2x}](https://tex.z-dn.net/?f=%5Csqrt%7B1-sin%5E2x%7D)
= -
= -
= -
= -
, thus
secΘ =
= - ![\frac{5}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B4%7D)
---------------------------
Using the identity
tan x =
, then
tanΘ =
= -
× -
= ![\frac{3}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7D)
Is this even a question, it seems to be more of a statement..
Answer:
D. Segment YZ is located at Y(0,1) and Z(−2,1) and is one-third the size of segment Y'Z'
Step-by-step explanation:
When you dilate a point by a factor of x from the origin, you multiply its coordinates by the same factor.
Thus, if the coordinates of the original point are (1,2) and the scale factor is 3, those of its image are (3,6).
If Y'Z' has endpoints at Y'(0,3) and Z'(-6,3) and was dilated by a factor of 3, the coordinates of the endpoints of the pre-image were ⅓ those of the image.
The figure below shows the segments YZ and Y'Z'.
