Answer:
Step-by-step explanation:
I'm assuming you're not doing the pre-calculus version of this equation where your angle is in radians. So we'll do the Geometry version which looks like this:
Our angle is 30 and our radius is 4, so we fill in accordingly:
(this is if you multiply in pi. We'll find the answer in terms of pi as well).
AL = 
and
AL = 2.09433 inches
In terms of pi, the answer would be
AL = 
inches
The center of a circle whose equation is x^2 +y^2 – 12x – 2y +12 = 0 is (6,1)
<h3>Equation of a circle</h3>
The standard equation of a circle is expressed as:
x^2 + y^2 + 2gx + 2fy + c = 0
where:
(-g, -f) is the centre of the circle
Given the equations
x^2 +y^2 – 12x – 2y +12 = 0
Compare
2gx = -12x
g = -6
Simiarly
-2y = 2fy
f = -1
Centre = (6, 1)
Hence the center of a circle whose equation is x^2 +y^2 – 12x – 2y +12 = 0 is (6,1)

Answer:
Answer: 11,272
Step-by-step explanation: there are 52 weeks in a year multiplied by the median wage, which is 1001. Then minus 40,780.
Step-by-step explanation:
HOPE THIS HELPS!!!!!! :D
we have that
y = 3x - 2
10(x+3/5)=2y------> the second equation----->divide by 2 both sides
5(x+3/5)=y-----> y=5x+3
y=5x+3------> second equation written in slope-intercept form
so
case A) y=5x+3/10-----> is not equal to y=5x+3
case B) y=5x+3--->is equal to y=5x+3---------> is the answer
case C) y=1/5x+3/25-------> is not equal to y=5x+3
case D) y=1/2x+6-----> is not equal to y=5x+3
therefore
the answer is the option
B) y=5x+3
Answer:
Percentage profit=40%
Step-by-step explanation:
Cost price=120 Naira
Sold price=168 Naira
Profit=Sold price- cost price
=168-120
=48 Naira
Percentage profit=profit/cost price×100
=48/120×100
=0.4×100
=40%
Percentage profit=40%
