Answer:
B)
.
Step-by-step explanation:
The vertex form of the equation is given by
.
We plug in the vertex to obtain:
.
Since the graph passes through (5,5) and (9,5), they must satisfy its equation.
.
.

Divide both sides by 4.

Therefore the equation is:
.
Answer: 9.9 years.
Step-by-step explanation:
If interest is compounded continuously, then formula to compute final amount A =
, where P =initial amount, r= rate of interest , t=time.
Given: P= $61,000, r= 1.9% =0.019 , A = $ 73600
Substitute all values in formula

Taking natural log on both sides

Hence, the required time = 9.9 years.

Answer:
.
Step-by-step explanation:
Given the statement
If
, then E and F are mutually exclusive events.
If two events are mutually exclusive, they have no elements in common. Thus, P(E∩F)=0.
Therefore, the statement is always true as P(E∩F)=0
For mutually exclusive events:
.
Answer:
a constant
