I think BD is 16 and EC is 9. hope this helps
Area of circle = pi x r^2
= 22/7 x 40^2
= 5028.57
= 5030cm^2 (3 SF)
Answer:
Angle 5, 4, and 7.
Step-by-step explanation:
Angle 2 is vertical to angle 5, making them congruent.
Angle 2 corresponds with angle 4, making them congruent.
Angle 2 is an alternate interior to angle 7, making them congruent.
]
The rest of the angles just combine with angle two to make 180.
Answer:
Is non-linear
Step-by-step explanation:
It is a quadratic function
By functional analysis we have the following conclusion about the function given: The domain for f(x) is all real numbers greater than or equal to 2.
<h3>How to determine the domain of a function with radical components</h3>
Domain is the set of x-values such that the value of the function exists. By algebra we know that the domain of polynomials is the set of all <em>real</em> numbers, whereas the domain of <em>radical</em> functions is the set of x-values such that y ≥ 0. If we know that f(x) = 2 · x² + 5 · √(x - 2), then the domain is restricted by the <em>radical</em> component and defined by x ≥ 2.
By functional analysis we have the following conclusion about the function given: The domain for f(x) is all real numbers greater than or equal to 2.
