Which is a good comparison of the estimated sum and the actual sum of 7 7/8 + 2 2/11?
Ipatiy [6.2K]
7 7/8 can be estimated to 8

2 2/11 can be estimated to 2

8 + 2 = 10


7 7/8 = 56+7/8 = 63/8

2 2/11 = 22+2/11 = 24/11

63/8 + 24/11 = 693+192/88 = 10.06

So do you see how similar 10 and 10.06 are to each other? :)

Explain why the function y=1-cosx is an even function
Oksanka [162]

A function is said to even if it returns the same output when given two opposite inputs:

f(x) = f(-x)

In your case, you have

f(x) = 1-\cos(x), \quad f(-x) = 1-\cos(-x)

And since \cos(x) = \cos(-x), the proof is concluded.

Let the average profit or loss in year 2006 be x millions, 


The average profit for the 8-year period, is the total sum of the profits (or losses) of each year, divided by 8:

so we have:

\displaystyle{ \frac{3.40+2.10+x+0.60+2.10+0.20+1.30+0.75}{8}=1

\displaystyle{\frac{10.45+x}{8}=1

10.45+x=8

x=8-10.45=-2.45


Answer: the loss in 2006, was 2.45 million dollars

If a cube has a side length of 4 1/2 cm, what is one way to write the volume of the cube?
atroni [7]

For this case we have that by definition, the volume of a cube is given by: V = s ^ 3

Where,

  • <em>s: Side of the cube </em>

We have that the cube side is given by:

s = 4 \frac {1} {2} cm

Therefore, replacing values we have:

V = (4 \frac {1} {2}) ^ 3 cm ^ 3

Answer:

One way to write the volume of the cube is:

V = (4 \frac {1} {2}) ^ 3 cm ^ 3
