Vector u has a initial point of (3,3) and a terminal point (7,2). whats the magnitude

√17

Step-by-step explanation:

As we go from (3, 3) to (7, 2), x increases by 4 and y decreases by 1.  We want the distance from one point to the other and will apply the Pythagorean Theorem to calculate that.  

In this situation, a^2 + b^2 = c^2 becomes

                           4^2 + 1^2 = 17, and so the length of the hypotenuse, and

                                                     thus the magnitude of this vector, is √17.

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
