Answer:
K(3,1),And K(1,-5),j(0,2) t
Step-by-step explanation:
Cotx = cosx/sinx
cscx = 1/sinx
If we plug these into your equation we get:
(cosx/sinx)/(1/sinx) - 1
Dividing by a number is the same as multiplying by its reciprocal so it can be rewritten as:
(cosx/sinx)(sinx) - 1
The two sinx's cancel each other out so we end up with cosx - 1

Answer:
3865.74 J/s
Step-by-step explanation:
mass of ice, m = 1 ton = 1000 kg
time , t = 24 hours
latent heat of fusion of ice, L = 334000 J/kg
Heat required to melt, H = m x L
where, m is the mass of ice and L be the latent heat of fusion
So, H = 1000 x 334000 = 334 xx 10^6 J
Rate of heat transfer = heat / time =
Rate of heat transfer = 3865.74 J/s
thus, the rate of heat transfer is 3865.74 J/s.
Answer: 25%
Step by step explanation:
1. Turn it into a fraction (5/20)
2. Turn the faction into a decimal by dividing the numerator (5) by the denominator (20). (5÷20=0.25)
3. Multiply the decimal (0.25) by 100, to convert it into a percentage. (0.25×100=25%)
