The diagram shows a logo made from 3 circles. Each circle has a centre 0. daisy says exactly 1/3 of the circle is shaded. is dai
marusya05 [52]

Daisy is not correct. The shaded part is 3/50 that of the whole circle.

<h3>Is Daisy correct?</h3>

In order to determine if Daisy is correct, the area of the circle and the area of the shaded part has to be determined.

Area of the circle = = πr²

Where :

π = pi = 22/7

r = radius = 4 + 3 + 3 = 10

10²π = 100π

Area of the shaded part = 3²π = 9π

Ratio of the areas = 9π / 100π

How do i evaluate a piecewise function
yulyashka [42]

Answer:

Piecewise functions are those where the behavior of the functions is dependent on the value of x.

For example the absolute value function f(x) = |x| is the same as

f(x) = -x , x<0

= x, 0<=x

To evaluate the value of f(x) = |x|, first determine if x is less than 0, equal to 0 or greater than 0. If x is less than 0, the value of |x| is equal to the negative value of x. In all other cases it is equal to the value of x.

This is the simplest piecewise function. There are other more complex functions where the function can take on more than 2 different behaviors based on the value of x.

Piecewise functions can also be identified from their graph. These have breaks in their graph, and each segment has a different behavior that is dependent on the value of x.

The evaluation of piecewise functions is done in the following way.

  • First, look at x and determine from the available behaviors which one would be followed for that particular value of x.
  • Next, we substitute x in that sub-function and determine the value obtained.

This complexity of this process varies with the piecewise function being evaluated. There are many functions which have a graph of infinite pieces.

A piecewise function is a function made up of different parts. More specifically, it’s a function defined over two or more intervals rather than with one simple equation over the domain. It may or may not be a continuous function.

Adam's age is 6 years less than one-third of Melissa's age. Adam's age is 18. How old is Melissa?
wariber [46]
What's up? this answer is B, 72

we can figure out that one third of melissa's age is 24 because 18+6= 24. simply eliminate the obvious incorrect answers, A and C. 78/3= 26 so it isn't D
72/3=24 it is B

best of luck with your studies
