Answer:

Step-by-step explanation:

A many-to-one function is a function that have y-values associated to more than one x-value.

Graphically speaking, if I draw an horizontal line through the graph, my horizontal line would cross the graph at least twice.

In the pictures, we can see that A is a parable, if I draw an horizontal line above y = 0, my line will go through the parable twice. For example, in y = 10 it will cross the parable at the point (-3,10) and (3,10). Therefore, this is a many-to-one graph.

The second picture is a one-to-one graph since there is only one y-value associated to each x-value.

The third graph is not even a function because by definition of function, each element of x should be associated with ONE element of y. In this case, x= 5 and x = 9 are associated to more than one y elements (the vertical lines that form two sides of the square) and therefore is not a function.

Answer:

none of the graphs shown

Step-by-step explanation:

A "many to one" function will be a graph that contains a single horizontal line and no points that can be on the same vertical line. Graph C has horizontal lines, but maps "many to many", rather than "many to one."

a vertical pole 10 meters high, casts a shadow 8 meters long. at the same time, a nearby tree casts a shadow 40 meters long. fin

weeeeeb [17]

To solve this problem you must apply the proccedure shown below:

1. You have the following information given in the problem above:

- The<span> vertical pole is10 meters high and casts a shadow 8 meters long.
- The tree casts a shadow 40 meters long.

2. Then, by similarity, you have:

x/10=40/8
8x=(10)(40)
8x=400
x=400/8
x=50 meters

3. Therefore, as you can see, the answer is: The height of the tree is 50 meters.</span>

A circle's radius that has an initial radius of 0 cm is increasing at a constant rate of 5 cm per second.

djyliett [7]

Answer:

a) $r(t)=5t$

b) $A=\pi\cdot r^2$

c) $A=\pi\cdot (5t)^2$

d) $A=25\pi t^2$

Step-by-step explanation:

We know that the circle is increasing its radio from an initial state of r=0 cm, at a rate of 5 cm/s.

This can be expressed as:

$r(0)=0\\\\dr/dt=5\\\\r(t)=r(0)+dr/dt\cdot t=0+5t\\\\r(t)=5t$

a) Radius of the circle, r (in cm), in terms of the number of seconds, t since the circle started growing:

$r(t)=5t$

b) Area of the circle, A (in square cm), in terms of the circle's radius, r (in cm):

$A=\pi\cdot r^2$

c) Circle's area, A (in square cm), in terms of the number of seconds, t, since the circle started growing:

$A=\pi\cdot r^2\\\\A=\pi\cdot (5t)^2$

d) Expanded form for the area A:

$A=\pi\cdot (5t)^2=25\pi\cdot t^2$

This is so stressful, i’ve tried everything and I don’t get this at all.

N = 5

These are similar triangles so their sides are proportional. The scale factor is the smaller triangle to the large triangle is

5/12.5 = 4/10 = 2/5

So if AB corresponds to QR (2 corresponds to n) then n = 5
