Answer:
3 grams
Step-by-step explanation:
We are going to take the mass of a bunch of little strips below the triangle "roof." To do this, we must figure out what formula for the mass we'll use, in this case, we'll use:
Mass of strip = denisty * area = (1+x)*y*deltax grams
now, because the "roof" of the triangle contains two different integrals (it completely changes direction), we will use TWO integrals!
**pretend ∈ is the sum symbol
Mass of left part = lim x->0 ∈ (1+x)*y*deltax = inegral -1 to 0 of (1+x)*3*(x+1) = 3 * integral -1 to 0 of (x^2 + 2x + 1) = 3 * 1/3 = 1
Mass of left part = lim x->0 ∈ (1+x)*y*deltax = inegral 0 to 1 of (1+x)*3*(-x+1) = 3 * integral 0 to 1 of (-x^2 + 1) = 3 * 2/3 = 2
Total mass = mass left + mass right = 1 + 2 = 3 grams
Answer:
Haha once again 1200 and 8.5 are the answers
Answer:
five degrees:)
Step-by-step explanation:
2 hours= -10
1 hour= half of ten
so you could say -5 or that it drops by five degrees every hour.
hope this helps!

Answer; 44
Answer:
Slope = ⅓ Y-intercept = -2
Step-by-step explanation:
by transforming the equation to y= ⅓x -2
then it becomes Y= ⅓x +(-2)
then you should get m= ⅓ and b = -2
