Evaluate the expressions:
h(x)=12/x
h(-2)
h(a)
Answer:
h(-2) = -6, h(a) = 12/a
Step-by-step explanation:
h(-2)
It says that you are supposed to do 12 divided by the number in the parentheses, so you have 12 / -2 = -6.
h(a)
Again, you have to do 12 divided by the number in the parentheses, so you have 12/a.

Step-by-step explanation:
Answer:
The size of the buttonhole should be 3 cm.
Step-by-step explanation:
The circumference is given by = where r is the radius of the circle.
Given is -
The circumference is given as = 9.42 cm
We can put this value in the formula and get;
=>
=>
r = 1.5 cm
As given that the hole needs to be the size of the button's diameter.
So, diameter = cm
Therefore, the answer is 3 cm.
