Answer:
9.17cm (3s.f.)
Step-by-step explanation:
Using Pythagoras Theorem,
5² = 2² + (Height of Triangle)²
Height of Triangle = 4.5826cm (5s.f.)
Area = ½ × 4 × 4.5826
= 9.1652cm (5s.f.)
= 9.17cm (3s.f.)
I would say that It is a rhombus.So it is A.
This equation has the next form:
To find if the equation has two complex solutions we have to check if the discriminant is negative, as follows:
Then, the first case has two complex solutions.
In the second case,
The discriminant in this case is:
Then, the second case has two complex solutions.
In the third case,
The discriminant in this case is:
Then, the third case has two real solutions.
In the fourth case,
The discriminant in this case is:
Then, the fourth case has two complex solutions.
(4(3h - 6)) / (1 + h)......h = -2
(4(3(-2) - 6)) / ((1 +(-2)) =
(4(-6 -6) / (1 - 2) =
(4(-12) / -1 =
-48/-1 =
48 <==
There are no lines of symmetry for the number four.
