Absolute value only removes the negative signs. Just multiply the numerator and the denominator
There is a formula for adding consecutive integers.
sum = (n * (n+1)) / 2
for summing 1 through 12 it is
sum = (12 * 13) / 2 = 156/2 = 78
The clock goes through two "12-hour cycles" in a day, so the answer is 2 * 78 or 156 times.
Answer:
Option B is correct option.
Step-by-step explanation:
We need to identify equations written in factored form.
Factored form: A factored form of expression is an expression broken down into a product of its factors.
In the given options A, C and D we don't have product of factors.
Only option B consists of product of factors.
So, Option B is correct option.
Answer:
r=2.808cm h = 100cm
then we get volume of cylinder that is 2744 As explained below
Step-by-step explanation:
Volume of cylinder = πr²h
Surface area of cylinder = 2πrh +πr² (1)
h= 2744 /πr²
put value oh h in equation (1)
Area =[2πr] 2744 /πr²
=[5488/r +πr²]
dA/dx=0
i.e 2πr=5488/r²
Solving this r.r= ∛5488/2π
=2.808
taking second derivation we get 100
