Answer:
C. a n =3000(1.05)n-1
Step-by-step explanation:
Arithmetic sequence formula, it is 1.05 because it increases by 1/20th each time. It is n-1 because n-1 is the correct form of arithmetic sequence formulas, without the n-1 it wouldn't work.
Answer:
A
Step-by-step explanation:
|((experimental - theoretical) / theoretical)| x 100
5.5 - 5.62 / 5.62 = -.0213
|-.0213| = .0213
.0213 x 100 = 2.13
Answer:
SAS since only one angle, the right angles are congruent on them. Two sides are marked congruent to each of their corresponding sides so it is side angle side.
Step-by-step explanation:
Answer:
∠ABC= 45°
Step-by-step explanation:
∠ABC= ∠BCD (alt. ∠s, AB//CD)
(2x +15)°= (3x)°
2x +15= 3x
3x-2x= 15 <em>(</em><em>-2x </em><em>on </em><em>both </em><em>sides)</em>
x= 15
Substituting the value of x:
∠ABC
= ∠BCD
= [3(15)]°
= 45°
Rise/Run=2/4= 1/2, the answer would be 1/2.
