Answer:
1. 23.8
2. 7.7
Step-by-step explanation:
<u>for the first blank</u>
use sin because x is opposite and 25 is hypotenuse
set up an equation:
sin(72)= (x/25)
multiply both sides by 25:
25(sin(72))= (x/25)25
25(sin(72))= x
multiply 25 by sin(72):
23.8 = x
<u>for the second blank</u>
use cos because x is adjacent and 25 us hypotenuse
set up an equation:
cos(72)= (x/25)
multiply both sides by 25:
25(cos(72))= (x/25)25
25(cos(72))= x
multiply 25 by cos(72):
7.7= x
First: the homogeneous solutions: the characteristic equation is4r^2 - 4r - 3 = 0which has roots r = 3/2, -1/2 hence the homogeneous solution isy = c1.exp(-x/2) + c2.exp(3x/2)
next you need the general form for the guess for yp and that isyp = A1cos(2x) + A2sin(2x)
Now substitute that into the equation and solve for A1, A2.
Answer:
The parallel line would be y = 4
Step-by-step explanation:
If a line is perpendicular to the to the x axis, then it is a horizontal line. All horizontal lines can be written in the form of y = (a number). That number can be found as the y-coordinate in the ordered pair given.
y = 4
Joint frequencies are the frequencies represented by a two-column table
The joint frequency that has the most flight is (c) Yellow Jet, going east
<h3>How to determine the highest flight</h3>
From the two-column table, the highest flight is 35.
35 is greater than other flights (33, 30 and 34) in the two-column table.
Also, 35 represents the flights of Yellow jets and going east
Hence, the joint frequency that has the most flight is (c) Yellow Jet, going east
