Answer:
The function is even because f(x) = f(−x).
Step-by-step explanation:
we know that
An even function is one for which
f
(−x)=f(x) for all x in its domain.
An odd function is one for which
f(
−x)
=−f(x) for all x in its domain
In this problem we have
so
therefore
f
(x)=f(-x) for all x in its domain.
Is a even function
Answer:
6ft
Step-by-step explanation:
You're given two points for f(t) and g(t) each. Two points, (x1,y1), and (x2,y2). In this case, x1 is always x1=0, since the time t starts counting at the earliest year given.
We know the form y=mx+b. m can be found a la (y2-y1)/(x2-x1), but remember x1 is 0. b can be found at f(0) or g(0), which we're already given; y1 for both cases.
I'm sorry, but I'm not giving a direct answer. Knowing the method, and being careful with calculations, should be more than sufficient.<span>it would be 22395-20808/5=317.4 f(t)
26508-26155/5= 70.6

c. 35 + 50x ≤ 1,325
Step-by-step explanation:
Abbey's total cost must be less then or equal to her total savings, i.e.
cost ≤ savings
it is given that cost = fixed registration fee and a monthly fee of $50 per month. Hence,
fixed registration + (monthly fee)*(number of months) ≤ savings
let the number of months be x,
hence
35 + 50x ≤ 1325(c)
There are 310 tens in 3100.
