Answer:By definition, perpendicular line are two lines that intersect at right angles. In other words, the angle made by two lines should be 90°. Therefore, the use of distance formula does not help because it only tells you if the sides are equal. It does not tell you about the intercepted angle.
A technique that can help you to know if two straight lines are perpendicular is is you find their slopes. Let's say the slope of line 1 is m1 and the slope of line 2 is m2. If m1*m2 yields a product of -1, then the lines are perpendicular. This is because if m1 is the negative reciprocal of m2, the lines are perpendicular. But if m1=m2, the lines are parallel, meaning they don't intersect at all.
Therefore, the answer is: Find the slopes and show that their product is -1.
hope it help
3x+(x-2)=10
4x=12
x=12/4=3
y=x-2=3-2=1
so, x=3 and y=1
Answer: (3;1)
Answer:
Step-by-step explanation:
don't worry fellow student, for I shall answer your question :D
P = (-10, 3)
Q = (-3, 3)
R = (-10, 8)
this is pretty easy- all you gotta do is look at the point and look where that point is on the x axis and y axis
hope this helps :>
For this question, 0.008 is the answer.
You can assume x is that number
X multiply 10 = 0.08
To get rid of 10, divide 10 by two sides
As a result, x = 0.008
C=2(pi)r
320=2(3.14)r
320/2=2/2(3.14)r
160=(3.14)r
160/3.14=(3.14/3.14)r
(about) 50.95=r
The Ferris wheel had a radius of about 51 feet.
I used 3.14 as pi
