Answer:
.2 <em>or </em>1/5
Step-by-step explanation:
First, calculate the total points by adding the two half's totals together.
7 + 18 = 25
Now, divide the number of points Mary scored by the total.
5 / 25 = 1/5
Answer:
(0,-9)
Step-by-step explanation:
The image of a point 
over a line 
is given by the co-ordinate rule:
→ 
So, when we reflect a point over the line , the x co-ordinate and y co-ordinate change their places.
Here, is 
. So, from the above rule, after reflection over the line , the image has the following co-ordinates:
Given:
To find:
The measure of angle MFZ.
Solution:
In triangles MFZ and PFZ,
(Right angle)
(Given)
(Common side)
(HL congruent postulate)
(CPCTC)
The value of x is 10.
The measure of angle MFZ is:
Therefore, the measure of angle MFZ is 19 degrees.
Tan ( A - B ) = ( tan A - tan B ) / ( 1 + tan A tan B )
tan A = 3 tan B/2
tan ( A - B ) = ((3 tan B/ 2)-tan B) / ( 1 + 3 tan² B/2)=
= (tan B/2) / ( 2 + 3 sin²B/cos²B )=
= (sin B / cos B) / (( 2cos² B+3sin²B)/cos²B)=
=( sin B cos B ) / ( 2 cos²B + 3 ( 1 - cos² B ) ) =
= (sin B cos B ) / ( 2 cos² B + 3 - 3 cos² B ) =
= ( sin 2 B ) / 2 ( 3 - cos² B ) =
= ( sin 2 B ) / ( 6 - cos² B )=
= ( sin 2 B ) / ( 5 + 1 - 2 cos² B )=
= ( sin 2 B ) / ( 5 + sin² B + cos ² B - 2 cos² B ) =
= ( sin 2 B ) / ( 5 - ( cos² B - sin² B ) ) =
= ( sin 2 B ) / ( 5 - cos 2 B ) - correct
