2 is a solution for True or False

Mathematics

Answer:

False

Step-by-step explanation:

When there is an open circle, it means that it can't be that exact number. If there is a closed circle, it can be that number. This is an open circle, and means that it is less than 2.

Answer:

False

Step-by-step explanation:

The open circle means you should not include the number it is on.

Ronald is 26 years old and starting an IRA (individual retirement account). He is going to invest $200 at the beginning of each
Licemer1 [7]

The formula for the future value A, given annual interest rate r, number of years t, and deposit amount P can be written as

... A = P(1 +r/12)((1+r/12)^(12t) -1)/(r/12)

Filling in the given numbers, you have

... A = 200(1+.0275/12)((1+.0275/12)^(12·39) -1)/(.0275/12) ≈ 167,868.30

The appropriate choice is $167,868.30.

_____

The formula is the one for the sum of a geometric series. It can be useful to consider the last deposit made as the first term of the series.

Explain how to graph a piecewise function
tester [92]
 <span>Just graph the function up to and/or including the points indicated. 

- if you have a piecewise function defined as y=x when x < 0 
y=-x when x >=1 

You would graph y=x from the negative direction up to 0 (but leaving an open circle on 0 because the function is not defined there 

Then start at point 1 (this time with a closed circle because y=-x is defined at 1, and graph y=-x.</span>
