Does this graph represent a function? Why or why not ?

Answer:

Step-by-step explanation:

One way to see if the graph is a function or not is by seeing if there is one output for every input. If the graph of the line touches a vertical line more than once, it is not a function, as this means there are two outputs for an input. For example, if a graph has a points that say (7,5) and (7, 10), the graph is not a function as 7 repeats more than once. Hope this helped!

A pole, 4m high, stands, vertically, on

Lostsunrise [7]

Answer:

Length of the shadow of the pole is 6.93 metres

Step-by-step explanation:

Given:

Height of the pole = 4 m

The angle sun makes with the horizontal = 30 degrees

To Find:

Length of the shadow of the pole = ?

Solution:

The tangent ratio is the value received when the length of the side opposite of angle theta is divided by the length of the side adjacent to angle theta

Let x be the length of the shadow

According to the tangent ratio

$tan {\theta} = \frac{opposite}{adjacent}$

On substituting the values,

$ta( {30^{o}) = \frac{4}{x}$

$x = \frac{4}{tan ({30^{o})}}$

$x =\frac{4}{0.57735027}$

x = 6.93 m

Will give medal to best answer!

mart [117]

We have two sides and one angle opposite to one of the known sides.

Begin with applying the Law of Sines to find angle A:
$\frac{sin A }{a}$ = <span> $\frac{sin C }{c}$

Then, solve for sin A:
</span>sin A = $\frac{a sinC}{c}$

Now, plug in numbers:
sin A = 19 × sin(38) / 10 = 1.17

We know that it does not exist an angle whose sin is bigger than 1, therefore
no triangle is formed.

A company makes 140 bags.

malfutka [58]

Answer:

Step-by-step explanation:

The question says we have 140 bags and we have 4 models

bags have buttons but no zips.

bags have zips but no buttons.

bags have neither zips nor buttons

bags have both zips and buttons

We don't know how many bags have zips and buttons but we know how many bags are produced. And other 3 types of bags number. So we can calculate

140-47-48-22=23

That means we have 23 bags that have zips and buttons

and

48 of the bags have zips too. that means we have 48+23=71 bags that have zips on them.

How are you in the bet nobody’s not going to help me on this question

Nataliya [291]

Answer:

See below.

Step-by-step explanation:

Party A

y = x^2 + 1

For each value of x in the table, substitute x in the equation with that value and evaluate y.

x = -2: y = (-2)^2 + 1 = 4 + 1 = 5

x = -1: y = (-1)^2 + 1 = 1 + 1 = 2

Do the same for x = 0, x = 1, x = 2

x y

-2 5

-1 2

0 1

1 2

2 5

Part B

Look at points (-2, 5) and (-1, 2). The change in x from (-2, 5) to (-1, 2) is 1. The change in y is -3.

Now let's look at two other points which have a change in x of 1. Look at points (0, 1) and (1, 2). The change in x from (0, 1) to (1, 2) is 1. The change in y is 1.

You can see that for the first two points, a change of 1 in x produces a change of -3 in y, but for the second two points, the same change of 1 in x produce a change of 1 in y. Since the same change of x does not always produce the same change in y, the function is nonlinear.
