Answer:
12 Pencils Sharpened
Step-by-step explanation:
Since the sharpener receptacle is emptied out 2 times every day.
Do 24*2 to get 48 pencils sharpened each day.
Now do 48/20 to get how many pencils a single person sharpens each day. Resulting in 2.4 pencils each day for 1 person.
Multiple 2.4 by 5 (Amount of days) to get 12 pencils in 5 days.
Answer:
two number not included in domain are x=0 and x=-5/2
Step-by-step explanation:
Let f(x)= 5/x and g(x)=2x^2+5x
WE need to find out the excluded value in the domain of f o g
f o g is the composition of functions
f o g= f(g(x))
lets plug in g(x) in f(x)
replace 2x^2+5x in f(x)
here we have 2x^2+5x in the denominator
to find the numbers that are in domain we set the denominator =0 and solve for x
Because when denominator becomes 0 the function is undefined
x=0 and 2x+5=0 (subtract 5 on both sides)
2x= -5 (divide by 2 on both sides)
x=-5/2
(going to number these 1-4 starting with the top one)
