The altitude of a triangle is increasing at a rate of 3 cm/min while the area of the triangle is increasing at a rate of 2 square centimeters per min. a) At what rate is the base of the triangle changing when the altitude is 10cm and the area is 100 square cm? Show the steps!

b) At what rate is the altitude of the triangle changing while the area of the triangle is increasing at a rate of 4 square centimeters per minute, the base is decreasing at a rate of 6 cm/min when the base is 10cm and the area is 100 square cm? Show the steps!

answer: 1, 3 and 5 are correct

step-by-step explanation:

if im not mistaking its

step-by-step explanation:  

really your just stupid if you don't know this

step-by-step explanation:

one way is to plot 2 points and connect them which is what the answer choices seem to be doing

it seems to be using the y intercept and the slope

y=mx+b, m=slope, b=y-intercept (where the line hits the y axis)

slope=rise/run

y-intercept is where the line croses the y axis which is the y value where x=0

you seem to have given the wrong slope (you didn't put a number in front of te x, it should be 2/3 or 3/2 looking at the answer options)

y=? x-1

m=? because of your fault

b=-1

so it has a slope of ? and y intercept of -1, meaning it pases through (0,-1)

so draw point (0,-1) (so answer is one of the first 2 option)

if slope is 2/3, then go up 2 and right 3 then draw line through those 2 points

if slope is 3/2, then go up 3 and right 2 then draw line through those 2 points
