Apr 27, 2017 · a = -5/3 = -1 2/3 There are two ways to find the answer, finding the constant of proportionality or just setting up a proportion. Finding the constant of proportionality : a = kbc Plug in the first set of numbers to find k: -10 = k * 12 * 2 -10 = 24k k = -10/24 = -5/12 Now use k to find a: a = -5/12 *8/1 *1/2 = -40/24 = -5/3 = -1 2/3 Using proportions: (a_1)/(a_2) = (b_1 c_1)/(b_2 c_2) (-10 ...
Answer: What if A varies jointly as B and C and inversely as the square of D, and A = 120 when B = 5, C = 2, and D = 9? How do you find A when B=12, C=9, and D=9? A varies with B When A = 10 B = 5 say So when A = 20 then B will be 10 Ie we can say A = k times B 10 = k times 5 So k = 2 What...

Joint Variation · A is said to vary directly as B and inversely as C if A ∝ B ∙ · or A = m ∙ B ∙ · (m = constant of variation) i.e., if A varies jointly as B ...
A joint variation is a direct variation with two or more variables. A varies jointly as b and c is equivalent to a = kbc, where k is a non-zero constant variation that is also known as the constant of proportionality. To find a when b = 7 and c = 9. Substitute k = 3, b = 7 and c = 9 in the equation of variation.
