You really do need to learn to read the notation.

1) The last sequence is the only one with a first term of -6 and common ratio of 4.

2) Asked and answered elsewhere. The 1st selection is the only one that reproduces the listed terms.

Write the equation of the line that is parallel to the x-axis and goes through the point (1, 4).

enyata [817]

Answer:

y=4

Step-by-step explanation:

A line that is parallel to the x-axis would have an equation of y= ______.

This is because a horizontal graph has a gradient of zero, thus the value of m in y=mx+c is zero.

y=0x +c

y= c

Since it passed through the point (1,4):

When x=1, y=4,

4= 0(1) +c

c= 4

Thus, the equation of the line is y=4.

The graph of the sine function looks like this- x is essentially the degree measure (in radians), while y is the value of the sine function. The graph of the cosine function looks like this- As with the sine function, analysis of the cosine function will show that the graph corresponds to the unit circle.

A rectangle has an area of x square units. The rectangle is dilated to create a new rectangle with an area of 9x square units. D

Alika [10]

The reactangle has an area of x.

So that means two numbers multiplied to each other equal to x. We can just think of itwo numbers that when multiplied equal to x as a and b.

So that means the side lengths are a and b. And ab = x (will be using this right next).

And it was multiplied by some scale factor that made the new area 9x. So if the scale factor is y, then:

$(y\times a)\times (y\times b)=9x$
$y^2ab=9x$
$y^2x=9x$
$y=3$

y can not equal to -3, because the length of a side of any polygon can never be negative.

So the dilation is 3.

And so if the dimension is 5 by 8.

Then the area is $5 \times 8=40$

And so then $x=40$

And then after the dilation, it would be $9x=9(40) = 360$

We could check it another way too. Since we said the scale factor is 3, then:

$( 5 \times 3) \times (8 \times 3) = 15 \times 24 = 360$

So basically 15 by 24 is the new dimensions :)

Which scenario most likely describes an example of plagiarism?

valina [46]

Answer: Taking a Photo of another photo displayed in an art gallery and claiming it as your own

Step-by-step explanation: Because you are claiming something as your own(when it's not) is considered plagiarism and no other situation is considered plagiarism but this one so really the process of elimination explains the answer to this question
