Not all parallelograms have symmetry. Some examples of some that do have symmetry are a rhombus, square or rectangle. Parallelograms sometimes have a crucial symmetry in which the two lines intersect.

Suppose T(n) = n(n +1)/2. Find T(10).

jek_recluse [69]

Answer:

D. 55

Step-by-step explanation:

$T(n) = \frac{n(n +1)}{2} \\ \\ T(10) = \frac{10(10 +1)}{2} \\ \\T(10) = \frac{10\times 11}{2} \\ \\T(10) = 5 \times 11 \\ \\ \huge \red{ \boxed{T(10) = 55}}$

Find the equation of the line. A. Y=-3/2x+1 B. Y=-2/3x-1 C. Y=2/3x+1 D. Y=3/2x-1. PLEASE HURRY!!!!!!!!

galben [10]

Answer:

y = $\frac{2}{3}$ x + 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 1) and (x₂, y₂ ) = (3, 3) ← 2 points on the line

m = $\frac{3-1}{3-0}$ = $\frac{2}{3}$

Note the line crosses the y- axis at (0, 1) ⇒ c = 1

y = $\frac{2}{3}$ x + 1 ← equation of line
