Find an area of a figure whose coordinates are a(-2, 2), b(2, 2), and d(-2, -2).

its a triangle 32

Step-by-step explanation:

first i plotted all the point

i treated this triangle like it was a square

so 8x8=64

then i divided 64/2 because 2 triangles equals a square

i then got the answer 32

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

b. 2 and 4
