Find the circumference of a circle with diameter, d
= 10.4cm.
Give your answer rounded to 3 SF.

Step-by-step explanation:

radius(r)=diameter/2

=10.4/2

=5.2 cm

circumference of a circle =2πr

=2*3.14*5.2

=32.656

=32.7

there are 25 people coming to the party

step-by-step explanation:

the text says that there will be 22 children at this party, 1 teacher, and 2 parents. so if you add them all together (22+1+2) it will equal 25. (=25)

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
