If Y Varies Directly As X, And Y Is 6 When X Is 72, What Is The Value Of Y When X Is 8?
If Y Varies Directly As X, And Y Is 6 When X Is 72, What Is The Value Of Y When X Is 8?. When y = 6, x = 72, k. First, we must determine k, which is the.
Y=54 if x=6 so we can write y=9(x) so y=k(x) clearly y is directly proportional to x. Now to remove the proportional sign, we use the constant of proportionality, let’s say k, as follows: A) 1/9 b) 2/3 c) 54 d) 96.
Find Y When X=50 And Z=5 Y Varies.
Direct variation means as x gets bigger, y gets bigger (or both smaller). X = 6 x=6 x = 6 when y = 32 y=32 y = 32 so substitute these values into the equation above to. The initial statement is y ∝ x z2.
⇒ 72 = K · 6 2 ⇒ K = 72 36 ∴ K = 2.
To find k use the given condition. ∴ x = k y 2 , where k is any constant. Substitute y = 6, x = 72 in above relation.
Does Y Varies Directly With X If Y54 When X 6?
Let us evaluate for 'k'. So has the direct variation. As such, we can use the formula y = kx when y varies directly as x to find the missing value.
The Equation For Direct Variation Is Y = Kx (Where K Is A Constant Of Variation).
Y =kx y = k x. If y varies inversely as x, and y=16 when x=2, find y when x=6 y varies directly as x and inversely as the square of z. View 30 other answers on parent question.
A) 1/9 B) 2/3 C) 54 D) 96.
How would you go about solving this direct. If y varies directly as x, and y is 6 when x is 72, what is the value of y when x is 8? Y ∝ x y ∝ x.
