Look for an addition/subtraction or multiplication/division patterns between numbers in the sequence.
1, 4, 9, 16, ...
if you look at what you add to get to the next number.
+3, +5, +7, ...
the pattern is adding consecutive odd numbers
16+9 = 25
25+11 = 36
36+13 = 49
1, 4, 9, 16, 25, 36, 49, ...

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.

Answer:
4
Step-by-step explanation:
The constant of proportionality is the ratio of y-values to corresponding x-values. We see that the y-value is 8 (at the top of the graph) when the corresponding x-value is 2.
k = 8/2 = 4
The constant of proportionality is 4.
