Find a+b,2a+3b,IaI, and Ia-bI. a[5, -12], b=[-3, -6]
DENIUS [597]

Answer: 1) 2\hat{i}-18\hat{j} 2) \hat{i}-6\hat{j} 3) 13, 4) 10.

Step-by-step explanation:

Since we have given that

\vec{a}=5\hat{i}-12\hat{j}\\\\and\\\\\vec{b}=-3\hat{i}-6\hat{j}

So, we need to find :

1) a + b is given by

5\hat{i}-12\hat{j}-3\hat{i}-6\hat{j}\\\\=2\hat{i}-18\hat{j}

2) 2a+3b is given by

2(5\hat{i}-12\hat{j})+3(-3\hat{i}-6\hat{j})\\\\=10\hat{i}-24\hat{j}-9\hat{i}+18\hat{j}\\\\=\hat{i}-6\hat{j}

3) |a| is given by

\sqrt{5^2+(-12)^2}\\\\=\sqrt{25+144}\\\\=\sqrt{169}\\\\=13

4) |a-b| is given by

\sqrt{(5+3)^2+(-12+6)^2}\\\\=\sqrt{8^2+6^2}\\\\=\sqrt{64+36}\\\\=\sqrt{100}\\\\=10

Hence, 1) 2\hat{i}-18\hat{j} 2) \hat{i}-6\hat{j} 3) 13, 4) 10.

100 points.<br> Find the surface area of the triangular prism. The unit is cm^2
nikklg [1K]
First we find the area of the two triangles on each side (keep in mind that they are equal/congruent to each other):

(24*10)/2 = 120 cm^2

Then you find the areas of the three rectangles that are left:

24*19 = 456 cm^2
26*19 = 494 cm^2
10*19 = 190 cm^2

Finally, to find the surface area of the prism:

120+120+456+494+190 = 1,380 cm^2
