Answer:ansur is b cuz i have that asignmint
Step-by-step explanation:
Wow, that is really eassy. It is 4! What did you thin k it would be? 4 is the correct answer! unless you ment 2x2 and that is 4 too
Answer:
Vertex: (-5,-4) Y-int: (0,21) X-int. = (-7,0), (-3,0)
Step-by-step explanation:
Find the dot product of the vectors
a = <ax, ay> and b = <bx, by>
The dot product is found by multiplying corresponding coordinates, and then sum all those products:
a * b = ax * ay + bx * by
________
For this question, you have these vectors
a = <5, 2> and b = <4, 5>
so the dot product is
a * b = 5 * 4 + 2 * 5
a * b = 20 + 10
a * b = 30 <----- this is the answer.
I hope this helps. =)
To solve this problem, we need to use the midpoint formula, where M = (x1+x2/2, y1+y2/2). To solve, we must plug in the given (x,y) values from our ordered pairs and then simplify, shown below:
(x1+x2/2, y1+y2/2)
( (16 + -6)/2, (5 + -9)/2 )
Now, we can begin to simplify by computing the addition in the numerators of both fractions.
(10/2, -4/2)
Next, we can finish the simplification process by dividing these fractions.
(5, -2)
Therefore, the midpoint of (16,5) and (-6,-9) is (5,-2).
Hope this helps!
