The answer is 18+30= 6(3+5) when you distribute the given one 18+30= 6(3+10) which was wrong, you get 18+60 so u need to replace the 10 with something that will equal 30 when multiplied; which is 5.

The explicit rule for an arithmetic sequence is an = -4 + (n - 1)7.
Mariana [72]
We know, the principle equation of Explicit rule is:
a(n) = a + (n - 1)d

Where, d = common difference

Compare the equations, 
Then, d = 7

In short, Your Answer would be: 7

Hope this helps!

An airline finds that if it prices a cross-country ticket at $300, it will sell 400 tickets per day. It estimates that each $10
lions [1.4K]

Answer:

price = $190

quantity =  950 tickets

Step-by-step explanation:

revenue = price * quantity

n = number of $10 price reductions

price = 300 - 10n

quantity =  400 + 50n

r = (300 - 10n)(400 + 50n)

recognize these as the factors of a quadratic that opens down

the vertex will therefor be the maximum revenue

the roots are:

300 - 10n = 0

300 = 10n

n = 30

400 + 50n = 0

50n = -400

n = -8

vertex is at mid point of the roots

n = (-8 + 30)/2

n = 11

price = 300 - 10n

price = 300 - 10(11)

price = 190

quantity =  400 + 50n

quantity =  400 + 50(11)

quantity =  950

For which pair of functions is (gºf)(a) =la|-2
nikklg [1K]

Answer:

<h2>              The third</h2>

Step-by-step explanation:

(g\circ f)(x) = g\big(f(x)\big)

so:

I.\quad (g\circ f)(a)=\sqrt{f(a)}=\sqrt{a^2-4}=\sqrt{(a+2)(a-2)}\\\\II.\quad (g\circ f)(a)=2f(a)-2=2(\frac12a-1)-2=a-2-2=a-4\\\\ \bold{III.\quad (g\circ f)(a)=\sqrt{f(a)-5}-2=\sqrt{5+a^2-5}-2=\sqrt{a^2}-2=|a|-2}\\\\ IV.\quad (g\circ f)(a)=4f(a)-5=4(3-3a)-5 = 12-12a-5=-12a+7
