Answer:

Yes

Step-by-step explanation:

All rhombuses are parallelograms, but not all parallelograms are rhombuses. All squares are rhombuses, but not all rhombuses are squares. The opposite interior angles of rhombuses are congruent. Diagonals of a rhombus always bisect each other at right angles.

$\bf (\stackrel{x_1}{0}~,~\stackrel{y_1}{3})\qquad (\stackrel{x_2}{2}~,~\stackrel{y_2}{-1}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-1-3}{2-0}\implies \cfrac{-4}{2}\implies -2 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-3=-2(x-0) \\\\\\ y-3=-2x\implies y=-2x+3$

Find the 81st term of the arithmetic sequence -28,-34,-40

VLD [36.1K]

Answer

sequence -28,-34,-40

1st term = -28

comman difference = -34 - (-28) = -6

comman term = a + (n-1)d

a= first term

d= difference

comman term = a + (n-1)d

= -28 + (n-1)(-6)

= -28 -6n +6

= -22-6n

1st term --> n =1 = -22 -6.1 = -22 -6 =-28

2nd term --> n =2 = -22 -6.2 = -22 -12 =-34

81st term --> n =81 = -22 -6.81 = -22 -486 = -508
