Answer:
402.12 + 804.24 = 1206.36
Answer:
3^2/15
Step-by-step explanation:
(^5sqrt3^2)^1/3
(3^2/5)^1/3
multiply the powers
3^2/5*1/3
3^2/15
We have been given that Marcus works for 26 hours each week and 48 weeks each year.
Thus in a year he works for
hours.
Now, we have been given that Marcus earns $8.40 per hour.
Therefore, in 1248 hours, he earns

Marcus has to pay tax if he earns more than $10,000. Now we have calculated that he earns $ 10483.2 which is higher than $10,000.
Therefore, Marcus has to to pat tax.
Equation of a tangent line of a curve is:
y- y0 = f´ (x0) (x - x0 ). In this case: x0=1, y0=1
f´(x)=

(Derivation)
f´(x0)=

y - 1 = 1/2 ( x - 1 )
y - 1 = 1/2 x - 1/2
y = 1/2 x - 1/2 + 1
y =
