Answer:
The profit per year will be $23916
Step-by-step explanation:
Cost price of 1 ft³ = $2.05
Selling price of 1 ft³ = $21.98
Profit = Selling price - cost price
profit = $21.98 - $2.05
Profit = $19.93
Profit on 1 ft³ is $19.93
If they sell 100 monthly, per year (12 months), profit will be
19.93*100*12
= $23916
<span>The additive inverse of −5 is +5, so 18 − (−5) = 23. </span>
(7/15)/(3/5)
easy
(a/b)/(c/d)=(a/b)(d/c)
invert and multiply (what it does is it cancels the bottom and makes it one)
(7/15)/(3/5)=(7/15)(5/3)=35/45=7/9
answer is C
Step-by-step explanation:
if we are taking in terms of domain.. is d set of number that we can put to the function with get division by zero .. squaroot of negative number,log of zero e.t.c
A) p(x)/m(x)= 1/squaroot(x) ÷ x²-4 which we know that x²-4 must not be equal to zero
because if is equal to zero we will have division by zero, which have contradicted the hypothesis of law of domain
x²-4 =! 0
(x-2)(x+2)=!0
x=!2 or x=!-2 because if is equal to that it's has contradicted d hypothesis
the answer is all real number except -2 and -
2
B)p(m(x))=p(x²-4) =1/squaroot of x²-4
note they are two things involve we must not get division by zero and root of negative number
we have all real number expect from -2 to 2
C)m(p(x))=m(1/root of (x))=(1/root of (x))²_4)
we have 1/x-4
so the answer is all real number expect zero
