Answer:
Wikipedia defines polynomials as "<em>an expression consisting of variables and coefficients</em>."
You would think that F(x) would not be a polynomial, but you could think of it like this:
F(x) = 0x + 1050
So, yes, I suppose constant terms by themselves are polynomials, it's just that they only have one term and would not really be called a <em>poly</em>-nomial.
You should probably research some more just in case.
Answer:
2.5cm^2
Step-by-step explanation:
so diameter is basically radius*2...to find radius(since area of circle is pi*r^2 we need to divide diameter by 2)
so 1.8/2=0.9
now,
pi*0.9^2
pi*0.81
2.5 cm^2
Let m and j be the current ages of Matthew and Jenny, respectively.
Now, Matthew is 3 times as old as Jenny, so the variables are in the following relation:
In 7 years, both of them will be 7 years older, i.e. their ages will be m+7 and j+7, and Matthew will be twice as old:
Now, remembering that m=3j, we can rewrite the second equation as
So, Jenny is 7 and Matthew is 21 (he's 3 times older).
In fact, in 7 years, they will be 14 and 28, and Matthew will be twice as old.
Answer:
I am pretty sure the answer is 23
Step-by-step explanation:
The answer is 23 because if you multiply 23 by 10 you get 230 which is the same if you divided 230 by 10 and you get 23.
Sin(35) = Opp./Hypo
sin(35) = 18/x
so
x = 18/sin(35)
x = 18 / 0.57357644
x = 31.38
x = 31.4
Answer is C. 31.4
