4. You are traveling to Chicago for a job interview. You leave Toledo, Ohio, at 5:45 A.M. and arrive in Elkhart, Indiana, at 8:1
Dvinal [7]

Answer:

48 mph

Step-by-step explanation:

First we need to find the distance from Elkhart to Chicago. Toledo to Elkhart is 136 miles and Toledo to Chicago 244 miles.

So the distance from Elkhart to Chicago can be calculated, since Chicago is farther from Toledo than Elkhart, as: distance(Toledo to Chicago) - distance(Toledo to Elkhart). These distances are given in the problem, so the distance from Elkhat to Chicago is: 244 miles - 136 miles = 108 miles.

This problem basically wants to know the slowest you can be yet still ariving on time. If you are the minimum speed, you will arrive in Chicago exactly at 10:30 A.M. So you have 2 hours and 15 minutes(10:30 A.M - 8.15A.M.) to drive 108 miles.

15 minutes is a fourth of a hour, so you have 2.25hours to go through 108 miles.

The minimum speed you must maintain is 108mph/2.25h = 48mph.

Trigonometry Identities help please
sesenic [268]

theta is in the fourth quadrant where the cosine is positive.


the third side in the triangle = sqrt (4 - 2) = sqrt2


So sin theta = -sqrt2/2 = Second choice (negative because sine is negative in 4th quadrant)


tan theta = - sqrt2 / sqrt2 = -1

N = x + y - n = 5<br> and part two<br> x = u + v = o<br><br> whats the answer?
Colt1911 [192]
Just substitute the value of x from second equation into first equation:
N = x + y - n = 5
N = u + v  + y - n = 5
N = 0 + y - n = 5

In short, N would be equal to y - n which is still equal to 5

Hope this helps!

elixir [45]
Longitud = L  Ancho = A
2A + 2L = 54
L = 2A    Sustituir este valor por L en la primera ecuación:
2A + 2(2A) = 54
2A + 4A = 54
6A = 54
A = 9
También porque L = 2A,
L = 2(9) = 18
