Answer:
Step-by-step explanation: That is a 90 degree angle. Using L is an example of a 90 degree angle, or a right angle, which is its common name.
The solutions or roots to this equation is found by solving for x. We can do this a couple ways either by FOIL or quad formula
3x^2+6x+6=0
3(x^2+2x+2)=0
x^2+2x+2=0 we cant FOIL this out so we use the quad formula
x= [(-b+\-sqrt(b^2-4ac))/2a]
x= -2+\- sqrt(4-4(1)(2))/2(1)
x= -1 +i , -1 - i
So we have complex roots since our quad formula returned a negative number. Whenever the quad formula answer is positive we have two roots/solutions, when it is zero we have one root/solution, and whenever it is negative we have Complex roots/solutions
Hope this helps. Any questions please just ask. Thank you.
It looks difficult but it’s pretty easy. Just use the Ln function to bring down the powers then simplify.
Answer:
Three hundred and fifty-four thousand, two hundred and ten =354210
Hundred thousand║Ten thousand║Thousand║Hundred║Tens║Ones
3 5 4 2 1 0
Step-by-step explanation:
Answer:
You are correct
It is C divided by PI
Step-by-step explanation:
c=pi x D
Using substitution method replace letters with numbers
12(c)=3(pi) x 4(d)
we want 4(d) the subject of the formula
4(d)=
12/3 =4
so it is 4(d)=12(c)/3(pi)
so D=C/PI
