<span>The rounded result is
4,000. If you just write "4,000", though, it's not clear whether there
are 1, 2, 3 or 4 significant figures, since trailing zeroes could be
significant (or not). For that reason, scientific notation is often
used. 4 × 10³ has one significant digit, 4.0 × 10³ has two, 4.00 × 10³
has three, and so on.
So, use either 4,000 or 4 × 10³, depending on what your teacher expects.</span>
Answer:
havent got tought this yet sorry wish i can help
Answer:
I have:
33 - 3N/44 marbles
N = marbles of Nicole
Step-by-step explanation:
Nicole + me = 44 marbles
m = 44 - N
m = me
N = Nicole
if i lose 1/4 of my marbles
4/4 - 1/4 = 3/4
i have left:
3/4 of my marbles
then:
m = 3(44-N)/4
m = 3*44/4 + 3*-N/44
m = 33 - 3N/44
I have finally:
33 - 3N/44
Answer:
f(x)=-4x^2-6x-1
g(x)=-x^2-5x+3
(f+g)(x) = (-4x^2-6x-1) + (-x^2-5x+3)
-4x^2 - 6x - 1 -x^2 - 5x + 3
= -5x^2 - 11x + 2
Step-by-step explanation:
Constant terms are just numbers (no x). The answer is 2
