Find the equation of the graph in function notation. Name your function "f" and use x as your variable.
kumpel [21]

Answer:

f(x)=\frac{1}{2}x-1

Step-by-step explanation:

The equation of the graph can be obtained using the formula:

\frac{x}{x-intercept}+\frac{y}{y-intercept}=1

From the graph, the y-intercept is -1 and the x-intercept is 2

We substitute these values to get:

\frac{x}{2}+\frac{y}{-1}=1

\frac{x}{2}-y=1

This implies that;

\frac{x}{2}-1=y

Or

y=\frac{1}{2}x-1

The function notation is

f(x)=\frac{1}{2}x-1

The ratio of the surface area of two cubes is 49:81. Find the ratio of there volumes.​
Liono4ka [1.6K]

Answer:

343 : 729

Step-by-step explanation:

A cube is made up of 6 square faces. If each face has a side length of a, we can find the surface area of that cube with the formula A=6a^2, since we'll have 6 faces with area a². Let's call the edge length of the first cube a and the edge length of the second cube b. The ratio between their surface areas is then 6a² : 6b², or simply a² : b². If we compare this to our given ratio 49 : 81, we can see that a² = 49 and b² = 81, or, square rooting both equations, a = 7 and b = 9.

The volume of a cube with a side length a is a³, so the ratio between our cubes here must be a³ : b³. Using the values for a and b we just found, this ratio becomes 7³ : 9³, which we can simplify to 343 : 729.
