Answer:

-1

Step-by-step explanation:

There are things called domain and range.

Domain is all the x values and range is all the y values.

Since in your picture the parabola only seems to be touching -1, that is your domain.

Answer:

The domain is all real numbers.

Step-by-step explanation:

Imagine the arrows extending forever. There is nothing to the left or right to stop them from growing infinitely far apart, and <u>including all numbers</u> in between! The domain is vast!

It may help to think of range like a mountain range with peaks and valleys. A parabola's vertex might be the peak of a mountain or the low spot in the valley.

In the graph shown here, the vertex is at (-1,0) The range can't go any higher. But the arrows point forever to negative infinity. So if the question asked about the range, it would be all numbers less than or equal to 0.

I hope this helps you understand better!

frozen [14]

From the given statement, we know the following...

0.35x = $247 where x = the orginial number

So if we solve for x by dividing by 0.35

x = $247/0.35 = $705.71

In parallelogram ABCD, AD = 12 in, m∠C = 46º, m∠DBA = 72º. Find the area of ABCD

dmitriy555 [2]

Answer:

The area of parallelogram ABCD is $78.42 \mathrm{in}^{2}$

Explanation:

Given:

AD = 12 in

$m \angle C=46^{\circ}$

$m \angle D B A=72^{\circ}$

To Find:

The area of parallelogram ABCD=?

Solution:

When we construct the parallelogram with the given data, we get a parallelogram formed by 12 cm as one side and an angle with 46 degrees.

The area of the parallelogram can be calculated by $a b * \sin (a n g l e)$

Substituting the value of a=12 we have

$\text { Area of parallelogram }=12 * \text { bsin } 46$

<u>To find the value of b, </u>

We know that area of a triangle can be expressed as,

$\text { Area of triangle }=(A b / 2) \sin (\text {angle})$

So,

$(12 * B D / 2) * \sin 46=(A B * B D / 2) * \sin 72$

Cancelling BD and 2 on both sides we get,

$12 * \sin 46=A B * \sin 72$

$A B=12 * \frac{\sin 46}{\sin 72}$

Therefore,

$b=\frac{12 \sin 46}{\sin 72}$

Substituting the value of b,

$=12 *\left(\frac{12 \sin 46}{\sin 72}\right) * \sin 46$

=78.42

So the area of the parallelogram is $78.42 \mathrm{in}^{2}$

Foe the AP given by a1,a2,......,an,...with non zero common difference, the equation satisfied are

user100 [1]

The given sequence is
a₁, a₂, ..., $a_{n}$

Because the given sequence is an arithmetic progression (AP), the equation satisfied is
$a_{n}=a_{1}+(n-1)d$
where
d = the common difference.

The common difference may be determined as
d = a₂ - a₁

The common difference is the difference between successive terms, therefore
d = a₃ - a₂ = a₄ - a₃, and so on..

The sum of the first n terms is
$S_{n}= \frac{n}{2} (a_{1}+a_{n})$

Example:
For the arithmetic sequence
1,3,5, ...,
the common difference is d= 3 - 1 = 2.
The n-th term is
$a_{n}=1+2(n-1)$

For example, the 10-term is
a₁₀ = 1 + (10-1)*2 = 19
Th sum of th first 10 terms is
S₁₀ = (10/2)*(1 + 19) = 100

A community in texas with a population of less than 5,000 residents may become which type of municipality?.

enyata [817]

Answer:

Some cities and towns are called municipali- ties. If a city government incorporates by citizen request, it is considered a municipal govern- ment. Cities in Texas operate under one of two types of law—general law or home rule. Small cities with populations of less than 5,000 may incorporate as a general-law city.
