Answer:
The value of ABC is 6.
Step-by-step explanation:
Consider the expression
Rationalize the denominator.
..... (1)
The answer in the form
.... (2)
On comparing (1) and (2), we get
We need to find the value of ABC.
Therefore the value of ABC is 6.
Answer:
174
Step-by-step explanation:
I divided 2438 by 14 and got 174 mph.
<span>A direct variation is of the form
y = kx
where k is the constant of variation
In most cases k is positive in which case
y increase in direct proportion to an increase in x
Example
k = 2
x = 1, y = kx = 2(1)= 2
x = 3, y = kx = 2(3) = 6
Occasionally k is negative in which case
y decreases in direct proportion to an increase in x
Example
k = -2
x = 1, y = kx = (-2)(1) = -2
x = 3, y = kx = (-2)(3) = -6
---------------------------
This is not to be confused with an indirect variation which is of the form
y = k/x
where k is the constant of variation
Example
When k is positive y decreases inversely as x increases
k = 2
x = 1, y = k/x = 2/1 = 2
x = 3, y = k/x = 2/3 = 2/3
When k is negative y increases inversely as x increases
k = -2
x = 1, y = k/x = -2/1 = -2
x = 3 y = k/x = -2/3 = -2/3</span>
