<span>Vector Ā * Vector B = -10. This is the scalar dot product and can calculated by taking the magnitude in the x, y, and z of the two vectors and the operation is done.
The angle </span> Ɵ AB between vector Ā and vector B is 133.635°.
<span>2 Vector B * 3 Vector C = -1. A similar approach is done for this one.</span>
=16.7332
That is one side of the square, so multiply by 4

Answer:
Jarrett has 75 comics
Step-by-step explanation:
T = Number of comic books Toby has.
M = Number of comic books Mitch has.
J = Number of comic books Jarrett has.
Toby has 75% as many comic books as Mitch.
T = 3/4 * M
This is because 75% = 75/100 = 3/4
Jarrett has 25% more comic books than Mitch.
J = 5/4 * M
This is because 125% = 125/100 = 5/4
If Toby has 45 comic books, how many comic books does Jarrett have.
1) Substitute T = 45 and Solve for M
T = 3/4 * M
45 = 3/4 * M
45 ÷ 3/4 = M
45 * 4/3 = M
180/3 = M
M = 60
2) Substitute M = 60 and Solve for J
J = 5/4 * M
J = 5/4 * 60
J = 300/4
J = 75

Answer:
C = 0.175x + 5
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.
<em>A phone company has a monthly cellular data plan where a customer pays a flat monthly fee $5 and then a certain amount of money per megabyte (MB) of data used on the phone</em>
Given:
- Customer uses 80 MB
- The monthly cost will be $19.00 (flat monthly fee and then a certain amount of money per megabyte (MB) of data used on the phone)
So let:
- C is the cost of the data plan
- x is amount of money per megabyte (MB)
We can form the standard equation:
C = mx + b <=> C = mx + 5
In this situation, we have:
19 = m*80 + 5
<=> m = 0.175
So the a linear equation is: C = 0.175x + 5
Hope it will find you well
