Answer:
f'(x) = -1/(1 - Cos(x))
Step-by-step explanation:
The quotient rule for derivation is:
For f(x) = h(x)/k(x)
In this case, the function is:
f(x) = Sin(x)/(1 + Cos(x))
Then we have:
h(x) = Sin(x)
h'(x) = Cos(x)
And for the denominator:
k(x) = 1 - Cos(x)
k'(x) = -( -Sin(x)) = Sin(x)
Replacing these in the rule, we get:
Now we can simplify that:
And we know that:
cos^2(x) + sin^2(x) = 1
then:

Answer: 3 1/4 tons = 6500 tons
Step-by-step explanation:
3 tons is 6000 since 3 * 2000 = 6000
1/4 would be 25% of 2000 which would be 500
because if you take 500 four times it will be 2000
Remember:
x/y times z/t=(xz)/(yt) and
x/y+z/y=(x+z)/y
conver the bottom number to the same number as the 21/100 or convert 10 to 100
obviously multiply by 10
but msut multiply by 1 to keep same value
remember that 10/10=1 so
multiply 3/10 by 10/10
3/10 times 10/10=30/100
so add
30/100+21/100=(30+21)/100=51/100
Answer:
A, 2 is the y intercept not the zero
