Answer:
50000000000 if your combining them both or if separate Q1: 25000000 Q2: 2000
Step-by-step explanation:
2.5(10^7)(2(10^3))
=25000000*2000
=2.5*10000000*2*1000
=(2.5*2)*(10000000*1000)
=5*10000000000
=50000000000
If separate:
question 1:
2.5(107)
=2.5*107
=2.5*(10*10*10*10*10*10*10)
=25000000
question 2:
2(103)
=2*103
=2*(10*10*10)
=2000
I hope this helps!
You would do
3.14*r^2
which is 3
r=3
what you do is
3.14*3*3 which is 28.26cm^2 which is D
Answer: 900 boxes
Step-by-step explanation: When you take 9,000 and divide it by the number of books in a box(10) you get 900
Answer:
$367.38 is the cost to stain the entire deck.
Step-by-step explanation:
Here is what you need to know beforehand:
<em>Diameter</em> is <u>a line</u> that goes <u>through a circle</u>. <em>Radius</em> is <u>a line </u>that goes from <u>the edge of the circle all the way to the center</u>/<u>a line </u>that goes <u>halfway through the circle</u>.
--------------------------------------------------------------------------------------------------------------
<u>First, find the area of the circle. Here is the formula:</u>
Area = 3.14 (Pi) x r²
Since radius is half of the diameter (as explained above), you'll need to divide the diameter in half: 12m/2 = 6m
So the formula will look like this:
Area = 3.14 x 6²
<u>Then, you just do the math:</u>
Area = 3.14 x 6²
Area = 3.14 x 36
Area = 113.04
The goal of the problem is to find the amount of money Emma needs. <u>Finally, all you need to do is multiply the amount it cost to stain per square meter by the total area of the deck:</u>
Answer = 113.04 x 3.25
Answer = 367.38
$367.38 is the cost to stain the entire deck.
The answer is: 
The inverse of a function
is another function,
, with the following property:

In other words, the inverse of a function does exactly "the opposite" of what the original function does, and so if you compute them both in sequence you return to the starting point.
Think for example to a function that doubles the input,
, and one that halves it:
. Their composition is clearly the identity function
, since you consider "twice the half of something", or "half the double of something".
In general, to invert a function
, you have to solve the expression for
, writing an expression like
. If you manage to do so, then
is the inverse of
.
In your case, you have

Multiply both sides by
to get

Square both sides to get

Finally, subtract 3 from both sides to get

Since the name of the variables doesn't really have a meaning, you can say that the inverse function is

As for the domain of the inverse function, remember what we said ad the beginning: if the original function goes from set A (domain) to set B (codomain), then the inverse function goes from set B (domain) to set A (codomain). This means that the inverse function is defined on an element in B if and only if that element belongs to the range of the original function, i.e. the set of the elements of the codomain
such that there exists
. So, we need the range of
.
We know that the range of
is
. When you transform it to
you simply translate the graph horizontally, so the range doesn't change. But when you multiply the function times
you affect both extrema of the range, turning it into
, which you can simply write as
