Answer:
<u>Fred paid US$ 310 to Social Security as a payroll tax</u>
<u>Fred paid US$ 72.50 to Medicare as a payroll tax</u>
<u>Fred paid 18% of his income to the Federal government as an income tax</u>
<u>Fred paid 5% of his income to the state government as an income tax</u>
Step-by-step explanation:
Fred's earnings in June were $ 5,000
A. Payment to Social Security
5,000 * 6.2% = 5,000 * 0.062 = 310
B. Payment to Medicare
5,000 * 1.45% = 5,000 * 0.0145 = 72.50
C. Federal Income Tax
900/5,000 = 0.18 = 18%
D. State Income Tax
250/5,000 = 0.05 = 5%
Answer:
1.) 15,708cm^2/s
2) 47,124cm^2/s
3.) 109,956cm^2/s
Step-by-step explanation:
Given the following:
50cm/s is the radius of the ripple per second , that is, radius(r) of ripple after t seconds = speed * time(t)
Speed = 50cm/s
r = 50t
.area of a circle(A) = πr^2
Rate of change of area with radius :
dA/dt = π2r . dr/dt
Speed of ripple created = 50cm/s; this is the rate at which the radius changes with time (dr/dt)
dr/dt = 50cm/s
Rate at which area is increasing with time:
dA/dt = π2r . dr/dt
dA/dt = π2(50t).50
dA/dt = 5000πt
After 1 second:
dA/dt = 5000π(1)
= 15,707.963cm^2/s
After 3 second:
dA/dt = 5000π(3)
= 47,123.889cm^2/s
After 7 second:
dA/dt = 5000π(7)
= 109,955.74cm^2/s
