Aramis is adjusting a satellite because he finds it is not focusing the incoming radio waves perfectly. The shape of his satelli

te can be modeled by (x - 4)^2 = 3(y - 3), where x and y are modeled in inches. He realizes that the static is a result of the feed antenna shifting slightly off the focus point. Where should the feed antenna be placed?
A. 0.75 in. below the vertex
B. 0.75 in. to the right of the vertex
C. 0.75 in. to the left of the vertex
D. 0.75 in. above the vertex

The answer is as follows: the correct choice is D) 0.75 inches above the vertex. To break it down: Consider the initial equation. The general parabola formula can be analyzed, indicating that the vertex is located at (4,3). Shifting the antenna to the focus point yields (4,3+0.75) = (4,3.75). Hence, the right answer is D) 0.75 inches above the vertex.

Based on the parabolic equation provided, the vertex is located at (4,3). The focus coordinates of the parabola can be deduced from the equation. Therefore, the focus is at the point (4,3.75).

A dental laboratory technician earns $14 per hour when she work days and $18 per hour when she works nights. One month she works
Inessa [12570]

Answer:

Her accumulated earnings for the month total $2208

Step-by-step explanation:

A dental lab technician receives $14 hourly for day shifts and $18 hourly for night shifts.

During one month:

She completed six 4-hour day shifts

Thus, total hours worked = 6 \times 4 = 24 hours

Three 8-hour day shifts = 3 \times 8 = 24 hours

Three 10-hour day shifts = 3 \times 10 = 30 hours

Total day hours = 24+24+30=78 hours

Hourly rate for daytime work = $14

Cost for 78 day hours = 14 \times 78 =1092

Five 6-hour night shifts= 5 \times 6 = 30 hours

Four 8-hour night shifts =4 \times 8 = 32 hours

Total night hours = 30+32=62 hours

Hourly rate for nighttime work = $18

Cost of 62 night hours = 62 \times 18=1116

Thus, total monthly earnings = $1092+$1116 = $2208

Consequently, her total pay for the month amounts to $2208

The half-life of carbon-14, 14C, is approximately 5,730 years. A bone fragment is estimated to have originally contained 6 milli
tester [12383]
The general equation for exponential decay characterized by a half-life (T) is expressed as N(t) = N_0(1/2)^(t/T), where N(t) signifies the amount remaining at time t, N_0 stands for the initial amount (at t=0), and T denotes the half-life of the substance. The half-life of carbon-14 is about 5,730 years. When starting with 6 mg of carbon-14, the equation for the remaining amount after t years would be established.

Leona [12618]

Answer:

The earnings gap, over a career spanning 30 years, between men and women totals $1,200,150

Step-by-step explanation:

Calculated annually.

The typical male earns $90,761 each year.

The typical female earns $50,756 per annum.

Therefore, the annual difference is:

90,761 - 50,756 = 40,005

Across 30 years:

30*40,005 = 1,200,150

The earnings gap over a 30-year career, when comparing men and women, is $1,200,150
