Help on the second graph
Deffense [45]

Answer:

<u>first graph:</u>

function.

Not one-one

onto

<u>Second graph:</u>

Function

one-one

not onto.

Step-by-step explanation:

We know that a graph is a function if any vertical line parallel to the y-axis should intersect the curve exactly once.

A graph is one-one if any horizontal line parallel to the x-axis or domain should intersect the curve atmost once.

and it is onto if any horizontal line parallel to the domain should intersect the curve atleast once.

Hence, from the <u>first graph:</u>

if we draw a vertical line parallel to the y-axis then it will intersect the graph exactly once. Hence, the graph is a function.

But it is not one-one since any horizontal line parallel to the domain will intersect the curve more than once.

But it is onto, since any horizontal line parallel to the domain will intersect the curve atleast once.

<u>Second graph</u>

It is a function since any vertical line parallel to the co-domain will intersect the curve exactly once.

It is not one-one since any horizontal line parallel to the x-axis does not intersect the graph atmost once.

It is not onto, since any horizontal line parallel to the domain will not  intersect the curve atleast once.

The equation c= 0.25n can be used to find the cost (c) of buying n number of apples.
aksik [14]

Answer:

(a) The constant of proportionality is 0.25

(b) 1 apple = $0.25

(c) $3 = 12 apples

Step-by-step explanation:

Given

c= 0.25n

Solving (a): The constant of proportionality;

For an equation:

c=kn

Where

k = constant of proportionality

By comparing: c=kn to c= 0.25n

k = 0.25

Hence, the constant of proportionality is 0.25

Solving (b): What information does k = 0.25 gives.

It represents the unit rate.

<em>So, it means that 1 apple costs $0.25</em>

<em></em>

Solving (c): Number of apples for $3.

This means that c = 3

Substitute 3 for c in c= 0.25n

3 = 0.25n

Make n the subject

n = \frac{3}{0.25}

n = 12

Find the value of y.
Elodia [21]

Answer:

<h2><u><em>94°</em></u></h2>

Step-by-step explanation:

Find x

(180 - 36) : 2 =

72°

so angle 2x is 144°

sum of all interior angles = 720°

Find y

720 - 144 - 111 - 105 - 165 - 101 =

94°
