Answer:

y = 5, 3; x = 171, 155

Step-by-step explanation:

8y - 15 = y^2

y^2-8y+15=0

y^2-3y-5y+15=0

y(y-3)-5(y-3)=0

(y-5)(y-3)=0

y can be 5 or 3.

x = 180 - (8y - 15)

x = 180 - (8(3)-15)

x = 180 - 9

x = 171

x = 180 - (8(5) - 15)

x = 180 - 25

x = 155

If avogadro's number of pennies is divided equally among the 231 million men, women, and children in the united states, how many

Anon25 [30]

2.607 x 10^13 dollars per person. Avogadro's number is approximately 6.0221409x10^23. So divide by the 231 million people. Giving (6.0221409 x 10^23) / (231 x 10^6) = 0.02607 x 10^17 = 2.607 x 10^15 pennies But we want dollars, so divide by 100 2.607 x 10^15 / 100 = 2.607 x 10^13 dollars

The sequence an = one third(3)n − 1 is graphed below: coordinate plane showing the points 2, 1; 3, 3; and 4, 9 Find the average

Maru [420]

The given sequence is:

$a(n)= \frac{1}{3} (3)^{n-1}$

a(2)=1
a(3)=3
a(4)=9

We are to find the average rate of change between n=3 and n=4 for the given function.

Average rate of change = $\frac{a(4)-a(3)}{4-3} = \frac{9-3}{1}=6$

So the average rate of change for the given function from n = 3 to n = 4 is 6
