Answer:
Option (2) and (4) are correct.
and
are points on the unit circle.
Step-by-step explanation:
Given : Some points of circles.
We have to choose which points could be points on the unit circle.
We know, the equation of circle is
..........(1)
where r is radius of circle.
We check each point for x and y values on the equation of circle and see which point gives radius = 1
Thus,
1)
Put in LHS of (1) , we have,
Simplify, we have,
Thus, is not a point on the unit circle.
2)
Put in LHS of (1) , we have,
Simplify, we have,
Thus, is a point on the unit circle.
3)
Put in LHS of (1) , we have,
Simplify, we have,
Thus, is not a point on the unit circle.
4)
Put in LHS of (1) , we have,
Simplify, we have,
Thus, is a point on the unit circle.
Thus, and
are points on the unit circle.
Answer:
$1032.60
Step-by-step explanation:
Given data
salary = $950 every two weeks
tax rate = 8%
let the initial pay be x
and let the pay after tax deduction be p
p= x-8/100x
Hence the equation for his pay is
subsitute
950=x-0.08x
950= 0.92x
divide both sides by 0.92
x= 950/0.92
x=$1032.60
The employee make $1032.60 every two weeks before taxes
