Harmony earns a $42,000 salary in the first year of her career. Each year, she gets a 4%, percent raise.
marysya [2.9K]

Answer:

42000*1.04^(n-1)

Step-by-step explanation:

4% is equal to 0.04, a raise is 1+0.04=1.04

1.04 is now the number we are multiplying by to get a new yearly salary for Harmony.

42000*1.04^(n-1) since n is how many years after she has the job you have to raise it to the power and subtract one.

Indicate the method you would use to prove the two A's . If no method applies, enter "none".
Natalija [7]

Answer:

The method would use to prove that the two Δs ≅ is AAS ⇒ D

Step-by-step explanation:

Let us revise the cases of congruence:  

  1. SSS ⇒ 3 sides in the 1st Δ ≅ 3 sides in the 2nd Δ
  2. SAS ⇒ 2 sides and including angle in the 1st Δ ≅ 2 sides and including angle in the 2nd Δ
  3. ASA ⇒ 2 angles and the side whose joining them in the 1st Δ ≅ 2 angles and the side whose joining them in the 2nd Δ
  4. AAS ⇒ 2 angles and one side in the 1st Δ ≅ 2 angles and one side in the 2nd Δ
  5. HL ⇒ hypotenuse and leg of the 1st right Δ ≅ hypotenuse and leg of the 2nd right Δ  

In the given figure

∵ The two triangles have an angle of measure 30°

∵ The two triangles have an angle of measure 70°

∵ The two triangles have a side of length 10

∴ The two triangles have two equal angles and one equal side

→ By using rule 4 above

∴ The two triangles are congruent by the AAS rule

∴ The method would use to prove that the two Δs ≅ is AAS
