PLEASE PLEASE PLEASE ANSWERRR Carla and Jonah are working together to determine if quadrilateral CDEF with coordinates C(2, 3), D(1, 2), E(4, 1), and F(5, 3) has a right angle.

Carla sets up the following equations:

slope of segment CD equals 2 minus 3 all over 1 minus 2

slope of segment DE equals 1 minus 2 all over 4 minus 1

Jonah sets up the following equations:

slope of segment CD equals 2 minus 3 all over 1 minus 2

slope of segment EF equals 3 minus 1 all over 5 minus 4

Who is on track to get the correct answer and why?

A(Carla is on the right track because she is finding the slopes of the opposite sides to check for right angles.

B( Carla is on the right track because she is finding the slopes of consecutive sides to check for right angles.

C(Jonah is on the right track because he is finding the slopes of the opposite sides to check for right angles.

D(Jonah is on the right track because he is finding the slopes of consecutive sides to check for right angles.

Christine wong has asked dave and mike to her move into a new apartment on sunday morning. she has asked them both, in case one of them does not show up. from past experience, christine knows that there is a 40% chance that dave will not show up and a 30% chance that mik a. what is the probability that both dave and mike will show up? (round your answer to 2 decimal places.) b. what is the probability that at least one of them will show up? c. what is the probability that neither dave nor mike will show up? (round your answer to 2 decimal places.)e will not show up. dave and mike do not know each other and their decisions can be assumed to be independent.

At river bank, checking account customers earn 0.75% interest a month on their account balances, pay no service fees for writing checks, and pay a monthly $2.00 financial charge. calculate the income earned in one month on the checking account for a customer with an account balance of $1,000. a. $4.25 b. $5.50 c. $6.75 d. $7.25 checking account earnings at baker’s bank are expressed by the equation: i = -0.09x + 10.2. while the earnings at elite bank are modeled by: i = -0.02x + 7.5. in both cases, x is the number of checks written. at what number of checks will elite bank start generating more checking account income than baker's bank? a. 12 b. 25 c. 39 d. 42 emilio’s checking account had a balance of 728.32 at the beginning of the week. he wrote checks for the following amounts throughout the week: $99.48, $33.50, $18.23, and $72.05. he also deposited his paycheck in the amount of $1,109.90. what is his account balance at the end of the week? a. $1,192.35 b. $1,222.86 c. $1,540.52 d. $1,614.96
