Answer: -1.56i^ +1.07j^
Step-by-step explanation:Vector C = -1.56i^ +1.07j^
This question requires that we use the properties of the scalar product of two vectors to find the required x and y component.
The dot product of two perpendicular vectors is equal to and the product of two vectors that are not parallel is equal to a nonzero value.
These are the properties that have been used in solving this problem alongside solving the simultaneous questions generator.
Explanation:
The full solution can be found in the attachment below.
Thank you for reading and I hope this post is helpful to you.

A city planner wants to build a road parallel to 2nd Ave . What is the slope of the new road?
Answer:
0
Step-by-step explanation:
By inspection or finding points, we see that 2nd ave is perfectly flat, or in other words, has slope of 0.
If line 1 is parallel to line 2, it means their slopes are the same.
So, the new road parallel to 2nd ave has a slope of [tex]\boxed{0}[/tex].

Cameron White traveled 325 miles in 6 1/4
hours. What was his average speed per
hour?
Answer:

To find the average rate, divide the total miles traveled by the total amount of time.
325 miles / 6 1/4 hours = 51.68 miles per hr
order -.48, -.47, -.45, -.46 from least to greatest pls
Answer:
-0.48, -0.47, -0.46, -0.45
Step-by-step explanation:
Initially, you may think to put -0.45 as the least value out of the four. However, we are dealing with negatives. This changes the way we order the numbers.
Here's what you need to know:
The closer a negative number is to 0, the greater it is. The farther a negative number is to 0, the less it is. For instance, -1 is a lot closer to being a positive number as opposed to -14.
Now, you apply that concept to this question.
-0.45 is the greatest since it is closer to 0 than -0.48!
I hope you find this helpful :D

2x - 19
Step-by-step explanation:
Perimeter = sum of sides
First let's simplify each side
We can simplify each side by using distributive property. Distributive property is where you multiply the number on the outside of the parenthesis by the numbers on the inside of the parenthesis.
2(x + 5)
Distribute by multiplying x and 5 by 2
2 * x = 2x and 2 * 5 = 10
2x + 10
1/2(4x + 8)
Distribute by multiplying 4x and 8 by 1/2
1/2 * 4x = 2x and 1/2 * 8 = 4
2x + 4
-3(2x + 11)
Distribute by multiplying 2x and 11 by -3
-3 * 2x = -6x
-3 * -33
-6x - 33
Finally add all the simplified expressions ( remember that they represent the side lengths of the triangle )
2x + 10 + 2x + 4 - 6x - 33
Combine like terms
2x + 2x - 6x = -2x
10 + 4 - 33 = -19
Perimeter: -2x - 19
Use the distributive property to rewrite each expression. then evulate. 27.) -3(2x-6)
Answer: -6x + 18
Step-by-step explanation: multiply each expression in the brackets by -3
so, -3 x 2x = -6x and -3 x -6 will give you +18 or just 18
for a final answer of -6x + 18
