Answer:
No, it is not a right triangle.
Step-by-step explanation:
If the triangle was a right triangle, then the Pythagorean Theorem states that a^2 + b^2 = c^2. Let's test it on this triangle:
13^2 + 14^2 = 365, or c^2. If this is a right triangle, c should equal 15.
However, sqrt(365) = 19.1, which is not 15. So, the triangle is not a right triangle.
That is really easy how don't you know
Answer:
there should only be two points at 6 and 4
Step-by-step explanation:
[x-5]=1
x-5=+ 1 or -1
x-5= 1
x-5= -1
x=6 or 4
Answer:
The domain must be [1, ∞).
Step-by-step explanation:
To do this we need to ensure that the x-1 is not negative.
That is x must be >= 1.
Answer:
The digits that can replace are 5 and 4
Step-by-step explanation:
Let
x -----> the digit
we have
3,408 < 3,X30 < 3,540
Divide into two inequality
<em>Solve for the first inequality</em>
1) 3,X30 < 3,540
The digits that can replace X are -----> 5,4,3,2,1,0
<em>Solve for the second inequality</em>
2) 3,408 < 3,X30
The digits that can replace X are -----> 9,8,7,6,5,4
The solution are all values of X common in both inequalities
therefore
The digits that can replace are 5 and 4
