<h3>
Answer: -76 (choice C)</h3>
Explanation:
We're applying the dot product.
u dot v = 3*(-4) + (-8)*8
u dot v = -12 - 64
u dot v = -76
The idea is that we multiply the x coordinates together, and the y coordinates together separately. Afterward you add the products. The result of any dot product is a scalar value, aka a single number.
The dot product is useful in many applications. One of which is to determine if two vectors are orthogonal.
You would write the equation out as x=35x+500
You substitute x for 7 so it’s x= 35(7)+500
So the answer will be 745 dollars
Answer:
h = 7.7 cm
Step-by-step explanation:
you can create a proportion using Law of Sines
<u> sin 90 </u> = <u> sin 31 </u>
15 h
<u> 1 </u> = <u> 0.515 </u>
15 h
h ≈ 7.7
