Answer:
<h2><em>
sinθ - 4cosθ = 0</em></h2>
Step-by-step explanation:
Given the equation of a plane in rectangular coordinates to be y = 4x.
The cylindrical coordinates of the axis is as given below;
x = rcosθ
y = rsinθ
z = z
Since there is no z coordinate in the equation of the plane given, we will only substitute x = rcosθ and y = rsinθ into the equation y = 4x and simply the result as shown;
y = 4x
rsinθ = 4( rcosθ)
rsinθ = 4rcosθ
sinθ = 4cosθ
sinθ - 4cosθ = 0
<em>Hence the equation for the plane in cylindrical coordinate is expressed as sinθ - 4cosθ = 0</em>
Answer:
13
Step-by-step explanation:
x y
y=1/2x+3 and passes through the point (10,-5) 10 = x and -5 =y 1/2(10) - this mean times
-5 = 1/2(10) +3
1/2(10/1) = 1 x 10 and 2 x 1 = 10/2 = 5
-5 = 5 + 3 = 7
-5 = 7 + 5 + 7
+5 +5
= 13

11.6 is the correct answer.
Answer:

y = 1
Step-by-step explanation:
600,000 ÷ 1/2 = 300,000
c = 600,000
y = 1/2
x = 300,000
Answer:
x=5
Step-by-step explanation:
y= -x/2 + 5/2
substitute y=0
0= -x/2 + 5/2
solve the equation
x=5
