Step-by-step explanation:
The solution of the given equation is x = 2.1
What is an equation?An equation is a mathematical statement that shows that two mathematical expressions are equal.
For example, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.
Given that, an equation, 3ˣ = 10, we need to find the solution of it,
So, solving for x,
3ˣ = 10
Taking log both sides,
㏒ 3ˣ = ㏒ 10
Since, ㏒ aⁿ = n ㏒ a
Therefore,
x ㏒ 3 = ㏒ 10
x = ㏒ 10 / ㏒ 3
x = 1/0.477
x = 2.095
x ≈ 2.1
Hence, the solution of the given equation is x = 2.1

3 x 10
Answer:
10²
Step-by-step explanation:
Another way of phrasing "10 sets of 10 sit-ups" is "10 sit-ups, 10 times," or mathematically, 10 x 10. Another way of writing repeated multiplication is through exponents. Since we have 2 10's multiplied together, we can rewrite our expression as 10².

The point that is equidistant to all sides of a triangle is called the incenter.
The incenter is located at the intersection of bisectors of the interior angles of a triangle.
b)
The point that is equidistant to all vertices of a triangle is called the circumcenter.
The circumcenter is located at the intersection of perpendicular bisectors of the sides of a triangle.
c)
See the attachment
The blue lines and their intersection shows the incenter.
The red lines and their intersection shows the circumcenter.
As we see the red point- the circumcenter is closer to vertex B.

To find:
The solution of the given inequality.
Solution:
We have,
[tex]q+12-2(q-22)>0[/tex]
It can be written as:
[tex]q+12-2q+44>0[/tex]
[tex](q-2q)+(12+44)>0[/tex]
