Step-by-step explanation:
Given
(7,5) and (-5,4)
Required
Determine the dot product
Dot product is calculated using the following formula;

Let a = (7,5) and b = (-5,4);
The above formula becomes



Hence, the dot product of (7,5) and (-5,4) is -15
3/9 because it is the same as 1/3 or 2/6.
Answer:
Step-by-step explanation:
x = 1/2 ( a + b)
x = 1/2 (129 + 71)
x = 1/2 (200)
x = 100 °
you just have to remember that formula
