Answer:
D
Step-by-step explanation:
In order to find the midpoint of a line segment on a graph, you must add both "x" coordinates, then divide by 2.
Then, add both "y" coordinates, and divide by 2.
The equation of the line would be y = (1/2)x.
To find the equation of a line that is reflected through the line y = x, we just switch the x and y. Then, solve for y.
y = 2x
x = 2y
0.5x = y
Answer:
c. 35.34015106
Step-by-step explanation:
As with many problems of this nature, you only need to get close to be able to choose the correct answer. 22 minutes 45 seconds is just slightly less than 1/2 degree (30 minutes), so the tangent value will be just slightly less than tan(88.5°) ≈ 38. The appropriate choice is 35.34015106.
If you need confirmation, you can find tan(88°) ≈ 29, so you know the answer will be between 29 and 38.
__
The above has to do with strategies for choosing answers on multiple-choice problems. Below, we will work the problem.
The angle is (in degrees) ...
88 + 22/60 +45/3600 = 88 + (22·60 +45)/3600 = 88 +1365/3600
≈ 88.3791666... (repeating) . . . . degrees
A calculator tells you the tangent of that is ...
tan(88.3791666...°) ≈ 35.3401510614
Many calculators will round that to 10 digits, as in the answer above. Others can give a value correct to 32 digits. Spreadsheet values will often be correct to 15 or 16 digits.
Answer:
The Answer is b. 1.5Million
Step-by-step explanation:
Adult Population = 50 Million
Labor-Force Rate = 60%
Total Labor Force of Adult population = 50Million*60% = 30Million
Unemployment Rate = 5%
People Unemployment =
Total Labor force of Adult population * Unemployment rate
People Unemployment = 30Millon*5%
People Unemployment = 1.5Million
