Answer:
173.01
Step-by-step explanation:
To area of a sector or portion of a circle is found using:
![A = \frac{N}{360} \pi r^2](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7BN%7D%7B360%7D%20%5Cpi%20r%5E2)
Substitute N = 50 and A = 27.93.
It becomes ![27.93 = \frac{50}{360} \pi r^2\\27.93 = 0.139 \pi r^2\\200.94 = \pi r^2](https://tex.z-dn.net/?f=27.93%20%3D%20%5Cfrac%7B50%7D%7B360%7D%20%5Cpi%20r%5E2%5C%5C27.93%20%3D%200.139%20%5Cpi%20r%5E2%5C%5C200.94%20%3D%20%5Cpi%20r%5E2)
The area of the entire circle is 200.94. The area of the blue part of the circle can be found by subtracting the red section from the entire circle.
200.94 - 27.93 = 173.01
5.18 is irrational because it cannot be a fraction.
In this item we are given with the equation, 2x - y = 3. The equation contains two variables, x and y. We assume in this item that the value of x is independent of the value of y; however, y values depends on the given values of x. In parametric form, the equation would take the form,
f(x) = y = ax + b
where a is the numerical coefficient of x and b is constant. Transforming the given equation to this form,
f(x) = y = 2x - 3
Answer:
consecutive interior angles
Step-by-step explanation:
inside of the angle and consecutive to each other
Answer:
f(x) = 3(x + 8)(x - 2)
Step-by-step explanation:
The intercept form of a quadratic function is y = a(x - r)(x - s), where r and s are the x-intercepts and a is the vertical stretch/compression factor.
If the intercepts are at (-8, 0) and (2, 0), and the vertical stretch is 3, just substitute these values into the intercept form formula, and you're done!
