47.82 is rounded to 47.8 because the '2' in the hundredths column means you round down. The same goes for 74.31- it becomes 74.3 because the '1' in the hundredths column means you round down. 

47.8+74.3= 122.1

what is the total number of unique triangles that can be made with the side lengths of 4cm, 5cm, and 10cm can be drawn? PLS HELP
Novay_Z [31]

Answer:

One

Step-by-step explanation:

       First, we need to check a triangle with these sides <em>is</em> possible. Since 4 plus 5 is 9, and 9 is less than 10, we can make a triangle with these sides.

       To answer the question, we can only make one unique triangle. Why? They give us three lengths and a triangle has three sides.

            <em>However</em>, if they are counting a triangle in different positions the answer will be greater. Since it would just be the same triangle, I am going with the answer of only one.

Which function is the inverse of y=2^x
ivanzaharov [21]

Answer:

The inverse of

y

=

2

x

is

y

=

log

2

x

Explanation:

This is how to do it.

From the given

y

=

2

x

interchange the variables so that

x

=

2

y

then solve for y:

x

=

2

y

take the logarithm of both sides with base

=

2

log

2

x

=

log

2

2

y

log

2

x

=

y

and

y

=

log

2

x

The graph of

y

=

2

x

and its inverse

y

=

log

2

x

. They are symmetric with the line

y

=

x

graph{(y-2^x)(y-log x/log 2)(y-x)=0[-20,20,-10,10]}
