Given the function, f(x) = 9 - x :
To evaluate f(4), we must substitute 4 into the given function as an input value for x:
f(4) = 9 - 4
f(4) = 5
Therefore, f(4) = 5.
Answer:
Step-by-step explanation:One yard equals 0.9144 meter. Therefore 20 yards = 20 * 0.9144 = 18.288 meters
A=p(1+i/m)^mn
Interest earned
I=A-p
A=980×(1+0.08÷4)^(4×5)
A=1,456.23
I=1,456.23−980
I=476.23
A=7,200×(1+0.04)^(8)
A=9,853.69
I=9,853.69−7,200
I=2,653.69
A=15,520×(1+0.06÷2)^(2×4)
A=19,660.27
I=19,660.27−15,520
I=4,140.27
