<span>metric is very conveinient
1gram=1cm^3 of water
1m^3=1,000,000,000 grams
water is 18.015 grams per mole
(1,000,000 grams water)/(18.015 grams/mole) = 55509.3 moles
there are 6.02e23 molecules in 1 mole of water so
55509.3 moles * (6.0221E23) = 3.3428E27 molecules of water </span>in 1m^3 of water
so we have200 of those
200 times <span>3.3428E27=6.6856E29 molecules
answer is </span><span>6.6856 times 10^29 mlecules</span>
First square both sides to get:
c + 22 = (c + 2)^2
or
c + 22 = c^2 + 4c + 4
Move the terms on the left side to the right side:
c^2 + 3c - 18 = 0
Factor to get:
(c + 6) * (c - 3) = 0.
The solutions are c = -6 and c = 3.
Check to see if these answers work by plugging them into the original equation:
c = -6:
sqrt (-6 + 22) ?= -6 + 2
But, -6 + 2 is a negative number, and you can't get a negative from a square root. So, -6 is extraneous.
c = 3:
sqrt (3 + 22) ?= 3 + 2
5 = 5. So, 3 works.
The answer is: B
Answer:
Cubic binomial
Step-by-step explanation:
There are 2 terms, so it is a binomial.
The degree is 3, so it is cubic.
Therefore, the polynomial is a cubic binomial.
Answer:
924
Step-by-step explanation:
I got the answer because I multiplied all the numbers and got that and to find the area of something you sultiply
Answer:
f(x) = { x, -5 ≤ x < 0 and 3x - 3, 1 ≤ x < 5
Step-by-step explanation:
The equation of one line is y = x
The equation of the other line is y = 3x - 3
Altogether,
f(x) = { x, -5 ≤ x < 0 and 3x - 3, 1 ≤ x < 5
