Answer:23
Step-by-step explanation:
The dot product will have you multiply the corresponding coordinates and add up the products
v dot w = (6*(-7)) + (7*5) + (-3*2)
v dot w = -42 + 35 - 6
v dot w = -7 - 6
v dot w = -13
Answer: -13
Answer:
34
Step-by-step explanation:
A triangle will add up to a degree of 180, so if you add those 2 angles then subtract it from 180 you will get the answer. So, 115+31=146 then 180-146=34
So the answer is 34
Answer:
<h2><u>
50 ft³</u></h2>
Step-by-step explanation:
We know the formula for a rectangular prism is length × width × height
We also know all the sides so we can rewrite the formula replacing variables.
The length is 8, the width is 2
and the height is 2
8 × 2
× 2
Multiply which ever way is easy for you. I am just multiplying from left to right.
8 × 2
= 20
20 × 2
= 50
Now we get 50. Before we put our answer as 50, there are two more steps.
First we need to add the measurement unit which is feet or ft
We also need to add ³ since it is volume
<u>50 ft³ is our final answer</u>
