Answer:
a. ![u=\frac{4\sqrt{41}i }{41}-\frac{5\sqrt{41}j}{41}](https://tex.z-dn.net/?f=u%3D%5Cfrac%7B4%5Csqrt%7B41%7Di%20%7D%7B41%7D-%5Cfrac%7B5%5Csqrt%7B41%7Dj%7D%7B41%7D)
Step-by-step explanation:
The given vector is v= 4i - 5j
The magnitude of this vector is;
![|v|=\sqrt{(-4)^2+(-5)^2}](https://tex.z-dn.net/?f=%7Cv%7C%3D%5Csqrt%7B%28-4%29%5E2%2B%28-5%29%5E2%7D)
![|v|=\sqrt{16+25}](https://tex.z-dn.net/?f=%7Cv%7C%3D%5Csqrt%7B16%2B25%7D)
![|v|=\sqrt{41}](https://tex.z-dn.net/?f=%7Cv%7C%3D%5Csqrt%7B41%7D)
The unit vector u in the direction of v is;
![u=\frac{v}{|v|}](https://tex.z-dn.net/?f=u%3D%5Cfrac%7Bv%7D%7B%7Cv%7C%7D)
![u=\frac{4i - 5j}{\sqrt{41}}](https://tex.z-dn.net/?f=u%3D%5Cfrac%7B4i%20-%205j%7D%7B%5Csqrt%7B41%7D%7D)
![u=\frac{4i }{\sqrt{41}}-\frac{5j}{\sqrt{41}}](https://tex.z-dn.net/?f=u%3D%5Cfrac%7B4i%20%7D%7B%5Csqrt%7B41%7D%7D-%5Cfrac%7B5j%7D%7B%5Csqrt%7B41%7D%7D)
We rationalize to get
![u=\frac{4\sqrt{41}i }{41}-\frac{5\sqrt{41}j}{41}](https://tex.z-dn.net/?f=u%3D%5Cfrac%7B4%5Csqrt%7B41%7Di%20%7D%7B41%7D-%5Cfrac%7B5%5Csqrt%7B41%7Dj%7D%7B41%7D)
the right answer is 7 and 4 because the angles are between the two lines that are not the transversal and are on diagonal opposite sides of the transversal.
Answer: 60 yd
Step-by-step explanation:
Here: subdivided into 3 smaller pens (2w + w + w) extra widths for separation purposes (3 smaller pens)
180 yards of fencing material
180yd = 2L + 4w
180dy = 2*60 + 4w
60dy = 4w
w = 15yd, how wide can the rectangle can be with L = 60yd
