Answer:

12x⁴ - 15x³ + 18x²

Step-by-step explanation:

1. distribute -3x²

-3x² • 5x = -15x³

-3x² • -4x² = 12x⁴

-3x² • -6 = 18x²

2. combine terms and put in descending order (standard form)

12x⁴ - 15x³ + 18x²

640, 160, 40, 10, ...

WARRIOR [948]

Answer:

Option 3 and 5 are correct

Step-by-step explanation:

We have given a geometric series 640,160,40,10....

Common ratio of geometric series is $r=\frac{a_2}{a_1}$

$r=\frac{160}{640}=\frac{1}{4}$

Here our common ratio is less than zero

It will show the graph of exponential decay

Hence, option 5 is correct.

The general term of geometric series is $a_n=a\cdotr^(n-1)$

Domain will be all natural numbers since, geometric series take only natural numbers.

Here, values of "n" is domain

Hence, option 3 is correct.

Range can be any positive real numbers not only natural number

Range is the value of $a_n$

Hence, option 4 is discarded.

Graph can not be linear of a geometric series being exponential

Hence, option 2 is discarded.

Option 1 is discarded because it is exponential decay function so it can not be exponential growth.

Therefore, Option 3 and 5 are correct.

1. A parallelogram is a four sided figure that has two pairs of parallel, opposite sides. Parallelogram ABCD is

sveta [45]

Answer:

The reason is that the since the segment AB and the new line passing through A are both parallel to the segment CD and all points on the new line and the segment AB are the same perpendicular distance from CD and the segment AB and the new line which follow the same direction share a common point, A, then the line drawn must fall on AB

Step-by-step explanation:

The given information are;

The shape of the quadrilateral ABCD = A parallelogram

The direction of the line to be drawn = Parallel to CD

A point on the line to be drawn = Point A

Therefore, given that ABCD is a parallelogram, we have;

Segment AB is parallel to segment CD

All points on AB are equidistant from all points on CD

The perpendicular distance of point A from the lime CD = The perpendicular distance of point B from the lime CD

The line to be drawn is also parallel to CD with point A located on the line, therefore, given that the length of a line is infinite, and all points on two parallel lines have equal perpendicular distance from the each other, the point B on the segment AB which has the same perpendicular distance as the point A from the segment CD will be located on the new line passing drawn passing through A and parallel to the segment CD then the new line drawn must coincide with the segment AB.
