Answer:

37

Step-by-step explanation:

f(x) = 2x-1

g(x) =x^2 +3

f°g(x) = means put g(x) in for x into the function f(x)

f(g(x)) = 2 (g(x)-1

           =2(x^2 +3) -1

    Distribute

           = 2x^2 +6-1

           =2x^2 +5

Now we let x=-4

f(g(-4)) = 2 (-4)^2 +5

           =2(16) +5

            =32+5

            =37

About how many molecules of water are in a swimming pool that holds 200 m^3 of water ? Write your answer in scientific notation
ddd [48]
<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>

Which is the equation in slope-intercept form of the line that contains points A and C?
Delvig [45]
We have that
point C(-2,-4)
point A(-4,-2)

we know that
the equation of a line in the intercept form is
y=mx+b

Step 1
find slope m
m=(y2-y1)/(x2-x1)
m=(-2+4)/(-4+2)------> 2/-2-------> m=-1

Step 2
find the value of b
with m=-1 and point C(-2,-4)
-4=-1*(-2)+b--------> -4=2+b-------> b=-6
y=mx+b
y=-x-6

the answer is
y=-x-6
