What is the angle between v=(-7,8) and w=(5,3) 1) use the formula v1*v2=|v1||v2|cos(theta) to find the cosine of the angle between these vectors. 2)use the cosine of the angle to find the actual angle between the two vectors.

Step-by-step explanation:

vector v is -7i+8j

vector w is 5i+3j

Angle between vectors is given by

therefore applying above formula

-35+24=

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
