Given:
The equation of a line is
...(i)
The perpendicular line passes through the point (-1,4).
To find:
The equation of the perpendicular line.
Solution:
The slope intercept form of a line is:
...(ii)
Where, m is the slope and b is the y-intercept.
On comparing (i) and (ii), we get
Product of slopes of two perpendicular lines is -1.
Let the slope of perpendicular line is .
The slope of the perpendicular line is and it passes through the point (-1,4). So, the equation of the line is:
Add 4 on both sides.
Therefore, the equation of required line is .
Answer:
2x^2
Step-by-step explanation:
if you draw a diagonal, you will have two triangles with base x and height x
so area= 2 * 1/2 * b * h = b * h= 2x * x
Answer:
4
Step-by-step explanation:keep change flip 4/5 x 5/1 = 20/5= 4
Answer
i would think 2 centimeter
Step-by-step explanation:
this would never really happen in my opinion the height and diameter would decrease. but if it takes 8 for 4 the it should take 2 for 1 because it looks like its doubling
w = 50 - 2.5t
Is there a viable solution when time is 30 minutes? No, because by then the tub will be empty.
Hope this Helps!!
