A function can have one x-value for each y-value Or even, two difference x-values for one y-value.

And out of the four options, only A and C represent a function. The other two options have the same x value for two y-values.

One way to test if it is a function is by the vertical line test.

9. A 3D printer uses one spool of filament to produce 20 congruent solids. Suppose you want to produce similar solids that are 1
Evgesh-ka [11]

Answer:

15 figures

Step-by-step explanation:

To know with this, and knowing that each dimension is 10% longer, let's do a simple example assuming some random values.

Let's suppose that you have cylinder with a radius of 3 cm and height of 5 cm. The volume of this cylinder is:

V = π*(3)^2*5 = 45π cm^3

Now, if we raise the dimensions by 10%, the radius and height will be 3.3 and 5.5 respectively so, the new volume (V2) will be:

V2 = π*(3.3)^2*5.5 = 59.9π cm^3

So the ratio of both volumes is:

59.9π/45π = 1.331

This means that each new solid would have 1.331 times the volume of the original solid. Therefore, we can stablish a relation between the original figures and the new ones calling "x" the number of new figures so:

20 = 1.331x

solving for x:

x = 20/1.331

x = 15.03

You can round this to 15.

dangina [55]

Answer:

f(4) =22

Step-by-step explanation:

f(x)=3x+10

Let x=4

f(4)=3*4+10

    Multiply

f(4) =12+10

Add

f(4) =22
