hope so it's help you.....
<span><span>v⃗ </span>+<span>w⃗ </span>=<span>z⃗ </span></span> Now, you were given some component vector that relates to <span>v⃗ </span> so <span><span>k1</span>⟨3,2⟩=<span>v⃗ </span></span>.
And from <span>⟨3,2⟩</span> and 90 degrees you know <span><span>w⃗ </span>=<span>k2</span>⟨−2,3⟩</span> OR <span><span>w⃗ </span>=<span>k2</span>⟨2,−3⟩</span>. And you can find <span>z⃗ </span> by looking a the math of the points... from <span>(−3,−3)</span> to <span>(−2,2)</span> is over 1 and up 5 so <span><span>z⃗ </span>=⟨1,5⟩</span><span>.
</span><span>Start and end are points, so (-3, -3) and (-2, 2).

<span><span>v⃗ </span>+<span>w⃗ </span>=<span>z⃗ </span></span>
<span><span>v⃗ </span>=<span>k1</span>⟨3,2⟩</span>
<span><span>w⃗ </span>=<span>k2</span>⟨−2,3⟩</span>
<span><span>z⃗ </span>=⟨1,5⟩</span>
<span><span>k1</span>⟨3,2⟩+<span>k2</span>⟨−2,3⟩=⟨1,5⟩</span><span>

Answer:
48
Step-by-step explanation:
first , muntiply 40*125 = 5000( cost of 40 books in rs 125 each)
125-25 = 100
multiply 40*100= 4000
5000-4000= 1000
divide 1000/125 = 8
therefore , 40+8= 48
