Tonya and Leo each bought a cell phone at the same time. The trade-in values, in dollars, of the cell phones are modeled by the given functions, where x is the number of months that each person has owned the phone.

Tonya’s Phone Leo’s Phone
f(x) =490(0.88)x
x g(x)
0 480
2 360
4 270

phone has the greater initial trade-in value.

During the first four months, the trade-in value of Tonya’s phone decreases at an average rate
the trade-in value of Leo’s phone.

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

1/4 because there is 4 grades.

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

a. is correct
