Determine algebraically if each function is even or odd by substituting f(-x) for f(x). Show your work.

a. f(x) = 2x^2 + 5
b. f(x) = – 3x^3 + 2x

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)

uhhh idk u yolo?

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true

the answer to this in exact form is 4/35 but in decimal form its 0.1142857

hope this if needed hmu
