In triangle, ABD,

AD²= AB²+BD²

AB² = AD²-BD²

AB² = 18²-9² = 324-81 = 243

AB = √243

In triangle, ABC,

AC² = AB²+BC²

AC² = (√243)²+(13)²

AC² = 243+169

AC = √412

AC = 20.29

According to the given function, it is found that fewer than 38.1% of U.S. voters will use punch cards or lever machines starting from the year of 2004.

<h3>What is the function?</h3>

P(t) = -2.5t + 63.1

  • In which t is the number of years after 1994.

It will be fewer than 38.1% when:

P(t) < 38.1

Hence:

-2.5t + 63.1 < 38.1

-2.5t < -25

2.5t > 25

t > 10

Fewer than 38.1% of U.S. voters will use punch cards or lever machines starting from the year of 2004.

Darnel's retirement party cost $33, plus an additional $1 for each guest he invites. What is the maximum number of guests there
Karolina [17]

Answer: the maximum number of guests that he can invite would be 9

Step-by-step explanation:

Darnel's retirement party cost $33, plus an additional $1 for each guest he invites. Assuming Darnel wants to invite x guests to his retirement party, the total amount of money that Darnel would spend is

33 + x

if darnel can afford to spend a total of $42 on his retirement party, then

42 = 33 + x

x = 42 - 33 = 9
