Answer:
a) 9:11 am
b) 77°F
Step-by-step explanation:
a) From the clock shown in the image attached, we can see that the time that the sprinkler system is switched off is at 11:56 am. Since the strawberries are watered for a total of 2 hours and 45 minutes every day, the time that the sprinkler is switched on can be gotten by subtracting 2 hours 45 minutes from 11:56 am. Hence:
Time sprinkler system is switched on = 11:56 am - 2 hours 45 minutes = 9:11 am
b) Temperature in °Farenheit = (1.8 * temperature in degree Celsius) + 32°
Temperature in °Farenheit = (1.8 * 25°) + 32° = 45° + 32°
Temperature in °Farenheit = 77°F
Answer:
y=7/5x+26/5 and y=-5/7x+66/7
Step-by-step explanation:
if it's parallel, it needs to have the same slope, so the equation is y=7/5x+26/5. the perpendicular line is y=-5/7x+66/7.
Any vector that points in the same or opposite direction would be parallel. So you can just scale (-2, 3) by any real number <em>t</em> to get the vector (-2<em>t</em>, 3<em>t</em> ).
For example, if <em>t</em> = -1, you get the vector (2, -3); if <em>t</em> = 2, you get (-4, 6).
