What is the general term equation, an, for the arithmetic sequence 5, 1, −3, −7, . . . , and what is the 21st term of this seque

Sonja [21]

The general term is obtained by starting with the initial value 5 and then subtracting 4 each time you wish to generate a new term:

a2 = second term = 5+(2-1)(-4) = 5+(-4) = 1

General term:

an = nth term = 5+(n-1)(-4)

Thus, the 21st term is 5+(21-1)(-4) = 5 + (20)(-4) = -75 (answer)

Line segment XY has endpoints X(5,7) and Y(-3,3)

dem82 [27]

y=-2x+7

Step-by-step explanation:

line segment xy has endpoints x(5 7) and y(-3 3)

for the equation of the perpendicular bisector of line segment xy

slope of line segment xy = 7-3 / 5+3

= 4/8

=1/2

so slope of perpendicular bisector is -2

as m1m2= -1 or m1= -1/m2

As perpendicular bisector goes through midpoint of xy , let's find midpoint of xy

midpoint(x,y) = (5-3 / 2 , 7+3 / 2)

=(2/2, 10/2)

=(1,5)

find the equation of line(perpendicular bisector) passing through (1,5) and the slope -2

y-5 = -2(x-1)

y-5 =-2x+2

y=-2x+7

Wat is y(y^3+2y) expanded

Nadusha1986 [10]

Y( $y^{3}$ + 2y) in expanded form is: $y^{4}$ + $2y^{2}$ .

First, distribute. / Your problem should look like: $yy^{3}$ + y × 2y.
Second, simplify $yy^{3}$ to $y^{4}$ . / Your problem should look like: $y^{4}$ + y × 2y.
Third, simplify exponent. / Your problem should look like: $y^{4}$ + $y^{2}$ × 2.
Fourth, regroup terms. / Your problem should look like: $y^{4}$ + $2y^{2}$ , which is your answer.
