What is the area of a right triangle with a hypotensuse of 32 cm and one leg of 30 cm round your answer to the nearest unit if necessary?
Using Pythagoras' theorem and the area formula it is: 167 square cm to the nearest unit.
How do you factorize using the quadratic formula?
simplify.
What is the answer by using the quadratic formula 2a -46a plus 252 0?
The answer of the equation 2a -46a plus 252 = 0 using the quadratic formula is a = 5.25.
Proof of the derivative of the cosecant function?
Express the cosecant in terms of sines and cosines; in this case, csc x = 1 / sin x. This can also be written as (sin x)-1. Remember that the derivative of sin x is cos x, and use either the formula for the derivative of a quotient (using the first expression), or the formula for the derivative of a power (using the second expression).
How do you solve x to the 2nd power minus 2x minus 13 equal 0?
Using the quadratic formula, you should get two answers: 1 + sqrt(14) and 1 - sqrt(14).
How do you find power output?
by using tester
What is a disadvantage in using tidal energy?
its power output is not predictable
What is the watts if a 12 volt battery produces 2.7 amps?
The power output of a 12-volt battery producing 2.7 amps can be calculated using the formula: Power (watts) = Voltage (volts) x Current (amps). So, in this case, the power output would be 12 volts x 2.7 amps = 32.4 watts.
What is the mechanical output power while lifting a 300 gram mass 60 centimeters?
Not enough information. You can calculate the work (using the formula for potential energy), but to calculate the power, you would also need the time (how fast is this done?)
What is the efficiency formula of lever?
The efficiency of a lever can be calculated using the formula: Efficiency = (output force × output distance) / (input force × input distance) * 100%. It represents the ratio of the output work done by the lever compared to the input work applied to the lever.
What type of energy is formed when using a cassette player or recorder?
The main power output is in the form of heat but a small amount of power is also output as an electrical signal.
What is the output on this exhaust fan?
This fan is rated at 277 CFM using 120V of power.
What is the formula for joules using time and power?
The formula for calculating energy (in joules) using power and time is: Energy (Joules) = Power (Watts) x Time (seconds). This formula represents the amount of energy consumed or produced over a certain period of time at a specific power level.
Would a 17.4 Gigi watt plant power homes using 319636928 Khz of power?
To determine if a 17.4 gigawatt plant can power homes using 319,636,928 kilowatt hours, you would need to convert the plant's power output from gigawatts to kilowatts. 17.4 gigawatts is equivalent to 17,400,000 kilowatts. Therefore, the plant's power output is sufficient to power homes using 319,636,928 kilowatt hours.
A weightlifter raises a 90-kg barbell from the floor to a height of 2.2 m in 0.6 s What was his average power output during the lift?
The work done to lift the barbell can be calculated using the formula W = mgh, where m = mass (90 kg), g = acceleration due to gravity (9.8 m/s^2), h = height (2.2 m). After calculating the work done, the average power can be found using the formula P = W/t, where t = time taken (0.6 s). Calculating the work and dividing it by the time will give you the average power output of the weightlifter.
What is the volume of object that is round?
The volume of a round object, such as a sphere, can be calculated using the formula V = (4/3)πr^3, where r is the radius of the sphere.
What is the formula for watts using mph?
The formula for calculating power in watts using miles per hour (mph) is: Power (watts) = 0.0098 * mph^3
