Answer: \triangle ABD \sim \triangle CBD by SAS

Step-by-step explanation:

\overline{BD} \cong \overline{BD} by the reflexive property, so \triangle ABD \cong \triangle CBD by SAS. Since all congruent figures are similar, this means that \boxed{\triangle ABD \sim \triangle CBD} by <u>SAS</u>.

A 14 gram sample of a substance that's used to preserve fruit and vegetables has a k-value of 0.1092. Find the substance's half-
nignag [31]

Answer:

t = 6.3

Step-by-step explanation:

N=Noe^(-kt)

No = 14 grams

k = .1092

We want to find t when N = 7 or 1/2 of 14

N=Noe^(-kt)

7 = 14 e ^ (-.1092t)

Divide each side by 14

1/2 = e ^ (-.1092t)

take the natural log of each side

ln (1/2) = ln e ^ (-.1092t)

ln (1/2) = -.1092t

Divide each side by -.1092

ln (1/2)/ -.1092 = t

t≈6.3475

Rounding to the nearest tenth

t = 6.3
