Answer:
x-30=-15
Step-by-step explanation:
x-30=-15
subtact 30 from both sides
For this case, we must indicate which of the given functions is not defined for
By definition, we know that:
has a domain from 0 to infinity.
Adding or removing numbers to the variable within the root implies a translation of the function vertically or horizontally. For it to be defined, the term within the root must be positive.
Thus, we observe that:
is not defined, the term inside the root is negative when .
While if it is defined for
, your domain is given by all real numbers.
Adding or removing numbers to the variable within the root implies a translation of the function vertically or horizontally. In the same way, its domain will be given by the real numbers, independently of the sign of the term inside the root.
So, we have:
with x = 0: is defined.
with x = 0: in the same way is defined.
Answer:
Option b
A that a that is your answer iu hoped it helped you and its right
The area of any triangle is A = (1/2) (base) (height).
If the right triangle is not sitting
on its hypotenuse, then one leg
is the base, and the other leg is
the height: A = (1/2) (base leg) (height leg) .
If the triangle is isosceles, then
the legs are equal: A = (1/2) (either leg)²
You said the area is 18 in²: 18 in² = (1/2) (leg²)
Multiply each side by 2 : 36 in² = leg²
Square root each side: 6 in = leg
