Answer: Keith spent 3 hours renting the surfboard.
Step-by-step explanation:
h=hour
10.25h+25=55.75
55.75-25= 30.75
30.75/10.25= 3
and if you want to check you can do
10.25(3)+25=
which would equal to 55.75
If the point P(x, y) partitions the segment AB in the ratio 1 : 1, then the point P is midpoint of segment AB.
The formula of a midpoint of segment:
![A(x_A;\ y_A),\ B(x_B,\ y_B)\\\\P_{AB}\left(\dfrac{x_A+x_B}{2};\ \dfrac{y_A+y_B}{2}\right)](https://tex.z-dn.net/?f=A%28x_A%3B%5C%20y_A%29%2C%5C%20B%28x_B%2C%5C%20y_B%29%5C%5C%5C%5CP_%7BAB%7D%5Cleft%28%5Cdfrac%7Bx_A%2Bx_B%7D%7B2%7D%3B%5C%20%5Cdfrac%7By_A%2By_B%7D%7B2%7D%5Cright%29)
We have:
![A(13,\ 1)\to x_A=13,\ y_A=1\\B(-5,\ -3)\to x_B=-5,\ y_B-3\\\\P\left(\dfrac{13+(-5)}{2};\ \dfrac{1+(-3)}{2}\right)\to P\left(\dfrac{8}{2};\ \dfrac{-2}{2}\right)\to P(4,\ -1)](https://tex.z-dn.net/?f=A%2813%2C%5C%201%29%5Cto%20x_A%3D13%2C%5C%20y_A%3D1%5C%5CB%28-5%2C%5C%20-3%29%5Cto%20x_B%3D-5%2C%5C%20y_B-3%5C%5C%5C%5CP%5Cleft%28%5Cdfrac%7B13%2B%28-5%29%7D%7B2%7D%3B%5C%20%5Cdfrac%7B1%2B%28-3%29%7D%7B2%7D%5Cright%29%5Cto%20P%5Cleft%28%5Cdfrac%7B8%7D%7B2%7D%3B%5C%20%5Cdfrac%7B-2%7D%7B2%7D%5Cright%29%5Cto%20P%284%2C%5C%20-1%29)
Answer: C. (4, -1)
Answer:
![-2,1,4](https://tex.z-dn.net/?f=-2%2C1%2C4)
Step-by-step explanation:
we have
![y=x^{3}-3x^{2} -6x+8](https://tex.z-dn.net/?f=y%3Dx%5E%7B3%7D-3x%5E%7B2%7D%20-6x%2B8)
we know that
The zeros of the function are the values of x when the values of the function is equal to zero
In this problem the apparent zeros are
For ![x=-2](https://tex.z-dn.net/?f=x%3D-2)
![y=0](https://tex.z-dn.net/?f=y%3D0)
For ![x=1](https://tex.z-dn.net/?f=x%3D1)
![y=0](https://tex.z-dn.net/?f=y%3D0)
For ![x=4](https://tex.z-dn.net/?f=x%3D4)
![y=0](https://tex.z-dn.net/?f=y%3D0)
