To "rationalize the denominator" is another way to say, getting rid of that pesky radical at the bottom.
we'll simply start by multiplying top and bottom by the "conjugate" of the denominator, recall difference of squares, anyhow, let's do so
Given that an experiment results in one of the sample points E1, E2, E3, E4,
or E5.
Then P(e1) + P(e2) + P(e3) + P(e4) + P(e5) = 1
If P(E1)=0.1, P(E2)=0.1, P(e4)=0.2, and
P(E5)=0.3., then P(E1) = 1 - 0.1 - 0.1 - 0.2 - 0.3 = 0.3
Therefore, P(e3) = 0.3
Answer:
His balance is $4,849.65 after 5 years
Step-by-step explanation:
A = P(1 + r/n)^nt
A = future value = ?
P = present value = $4,500
r = interest rate = 1.5% = 0.015
n = number of periods = 4
t = time = 5 years
A = P(1 + r/n)^nt
= 4,500(1 + 0.015/4)^4*5
= 4,500(1 + 0.00375)^20
= 4,500(1.00375)^20
= 4,500(1.0777)
= 4,849.65
A = $4,849.65
His balance is $4,849.65 after 5 years
Answer:
A
Step-by-step explanation:
Between 4 and 5 where the vertex is. The axis of symmetry is a line going through the vertex. For a while it will be of the form x = a
In this case, the axis of symmetry is x = 4.5
