Answer:
The relation
is explained below.
Step-by-step explanation:
P(x, y) is a point on the circle. Q is the origin. Join PQ.
PQ is the radius.
Therefore, PQ = r
Draw PS perpendicular to the x-axis.
Now, ΔPQS is a right triangle.
By Pythagoros theorem,



Answer:
2y - 12x = 3
Step-by-step explanation:
gradient of line PQ= (7-8)/ 4+2
-1/6
gradient of perpendicular bisector of line PQ=
-1 ÷ -1/6
-1× -6
6
coordinates of the midpoint of line PQ
(-2+4)/2, (8+7)/2
(1, 15/2)
the perpendicular bisector passes through the midpoint of line PQ
Equation of the perpendicular bisector
y - 15/2 = 6(x - 1)
multiply through by 2
2y - 15 = 12(x - 1)
2y - 15 = 12x - 12
2y - 12x = 3
Answer:
Median for a: 50 because it is in the middle of the points
Median for b: 35 because it is in the middle of the points.
Step-by-step explanation:
What i do is i write all the numbers out as shown in graph and cross one out on both sides untill there is one left.
IQR A: 15
IQR B: 15
Find the 25 percentile the. the 75 pecentile then subtract the numbers off from eachother.
Have an amazing day!
<u><em>PLEASE RATE!</em></u>
Answer:
without doing the math, we can affirm that the percent in decrease in the price of the gloves is <u>not</u> the same as the percent increase of the goggles. decreasing $2 from $10 will have a lower decrease than an increase of $2 from $8 since $2 represents a higher portion of $8 compared to $10

Answer:
C. A rate with one (1) in the denominator
A unit rate is basically a ratio of something to one.
example:
if 10 bananas costs ten dollars then one banana would cost one dollar.
