Answer: First option is correct.
Step-by-step explanation:
Since we have given that
Amount invested = $396
Interest rate = 13% per year
Time = 3 years
We will use the "Exponential growth formula" i.e.
Here,
P denotes Principle amount
r denoted rate of growth
t denotes number of years,
So, it becomes
Hence, First option is correct.
Answer: The missing step is,
m∠OCP ≅ m∠ABC because corresponding angles made by the same transversal on the parallel lines are congruent.
Step-by-step explanation:
Given : ,
And,
We have to Prove : Angle PCQ is complementary to angle ABC
⇒
Proof: Since,
⇒
But, ( By angle addition postulate )
⇒ ( By transitive property of equality )
Since, ,
⇒ ( corresponding angles made by the same transversal are congruent)
⇒ ( By the definition of congruent angles )
This leads,
( by the transitive property of equality )
Thus, by the definition of complementary angles,
Angle PCQ is complementary to angle ABC
Hence proved.
