Given that the initial point of the vector is (1,-2) and the termination point of the vector is (0,0).
So, the tail of the vector is at point (1,-2) and the head of the vector is at (0,0). The vector, 
, has been shown in the figure.
The magnitude of the vector:
The direction of a vector is the angle made by a vector with the positive direction of the x-axis.
From the figure, 
Hence, the required vector having a magnitude 
and direction 
has been shown in the figure.
Answer:
B i think I'm kinda sure tho
b
51h + 35m
Explanation:
For the first option, you can’t combine two different terms. Both would have to be represented by h or by m to put the two together.
On the second option, you wouldn’t multiply the two together either because in the problem, Bianca is doing hair AND makeup which is a keyword for adding.
The third and final option is the correct one because it’s leaving the two values separate and still adding them together.
You can use some graph tools to draw three regressions for given data. On the attached diagram you can see:
- linear function - black line;
- quadratic function - red curve;
- exponential function - blue curve.
Since
you can conclude that for the given data the best fit is exponential function with rule
Answer: correct choice is C.
