Answer:
Neither, why... for it to be direct or inverse variation, the model has to fit either y=k/x or y=kx, it may not have a y-intercept at all if it is inverse variation and it must have a y-intercept of 0 for it to be direct variation.
Step-by-step explanation:
The statement y=2 is quite specific. Because k is positive, y increases as x increases. So as x increases by 1, y increases by 1.5. Inverse Variation: Because k is positive, y decreases as x increases. yx is a constant number -8. The constant of variation, k , is 23 . Inverse Variation
An inverse variation can be represented by the equation xy=k or y=kx .
That is, y varies inversely as x if there is some nonzero constant k such that, xy=k or y=kx where x≠0,y≠0 .
Suppose y varies inversely as x such that xy=3 or y=3x . That graph of this equation shown.
Answer:
2 and 7/8
Step-by-step explanation:
3 + 3/8 - 1/2
3 + 3/8 - 4/8
3 - 1/8
2 and 7/8
Answer:
Stands Steakhouse has 210 servers.
Step-by-step explanation:
5 servers to 1 cook.
5/1 = x/42
x = 5 * 42 = 210
Your answer would be A b=a+5
Answer:
V = 288.5 
Step-by-step explanation:
To find the volume of a cone, use this equation:
r = radius
h = height
We aren't given the height of the cone, just the length of the side. To find the height use the Pythagorean Theorem:
The value of 12.1 yds is the hypotenuse and the radius is the value of one of the legs. So, set it up like this:
Now, solve:
Distribute the square
Subtract 25 from 146.41
a = 11.01862
So, the height is equal to 11.01862 yds.
Now, we can plug everything into the volume equation:
Simplify (use calculator):
V = 288.5
So, the volume of the cone is equal to 288.5
