Hello!
The thing to know what solving problems like these is that slopes of perpendicular lines are opposite reciprocals of each other.
For example, if you are given that the slope of a line is 6, and are told to find the slope of a line perpendicular to it, you would flip the 6/1 to 1/6 and negate it. The slope of a line perpendicular to a line with a slope of 6 is -1/6.
Here, you have an equation of a line in slope-intercept form. Slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.
In y = 4x + 5, 4 is m, thus 4 is the slope.
The opposite reciprocal of 4 is -1/4.
Answer:
-1/4
Answer:
ANSWER: The ratio of the heights of cylinders A and B is 1:9.
Step-by-step explanation:
The volume of cylinder A is %28pi%29%28%283r%29%5E2%29%28h%29+=+9%28pi%29%28r%5E2%29%28h%29.
So tripling the radius in cylinder A makes the volume 9 times the volume of cylinder B. If the volumes are to be the same, the height of cylinder A must be 1/9 the height of cylinder B.
