Hello!
I believe that 8 cubes are needed to build the given figure
I hope this helps!
Answer:
![31^{\circ}](https://tex.z-dn.net/?f=31%5E%7B%5Ccirc%7D)
Step-by-step explanation:
We have been given that vector v has a direction of (5,3). We are asked to find direction angle for v to nearest degree.
We know that direction of vector with components
can be determined by
.
Upon substituting the components of given vector in above formula, we will get:
![\theta=\text{tan}^{-1}(\frac{3}{5})](https://tex.z-dn.net/?f=%5Ctheta%3D%5Ctext%7Btan%7D%5E%7B-1%7D%28%5Cfrac%7B3%7D%7B5%7D%29)
![\theta=30.9637565^{\circ}](https://tex.z-dn.net/?f=%5Ctheta%3D30.9637565%5E%7B%5Ccirc%7D)
Upon rounding to nearest degree, we will get:
![\theta\approx 31^{\circ}](https://tex.z-dn.net/?f=%5Ctheta%5Capprox%2031%5E%7B%5Ccirc%7D)
Therefore, the direction angle for vector v is 31 degrees.
Because then you can replace the variables with the actual value and see of the equation is true.
Use a variable to represent the number of hours the technician will work, plus the $50.
50+25x
This would be the expression used to find the amount of money the technician needs.
