Answer:
(a)Height of the platform=40 feet
(b)Initial Velocity=54 ft/sec
(c)4 seconds
Step-by-step explanation:
The equation gives the height of the baton, in feet, t seconds after it is thrown from the platform.
(a)Height of the platform
The Height of the platform is the height at which t=0
Height of the platform=40 feet
(b)To determine the speed at which the baton was thrown, we find the velocity, v(t).
(c)The baton will hit the ground when its height, h(t)=0
Since -0.625 is not valid, the baton will hit the ground 4 seconds after it is thrown.
This question is incomplete, the complete question is;
A household item uses 321 watts of electricity. This item is used for 27 hours each week. How much CO2 will be produced each week from this item? (assume 1.37 pounds of CO2 is produced per KWH of electricity used)
Answer: 11.87 lbs of CO2 will be produced each week from this item
Step-by-step explanation:
Given that;
Average wattage Wattage of the item = 321 watts
Time used = 27 hours each week
CO2 produced each week = ?
so;
Total electricity consume = 321 × 27 = 8667 watt = 8.667 kWh
given that; 1.37 pounds of CO2 is produced per KWH of electricity used
hence; CO2 generated by our item will be;
⇒ 8.667 kWh × 1.37
= 11.87 lbs
Therefore, 11.87 lbs of CO2 will be produced each week from this item
1/5(100x - 105y + 70) = 20x -21y + 14
Answer:
⏩62°
Step-by-step explanation:
x + 118°= 180° { Being co-interior angles }
x = 180° - 118°
x = 62°
