Answer:
hmm, i think is -2.2 if am correct.
Step-by-step explanation:
Given:
A plane is normal to the vector = -2i+5j+k
It contains the point (-10,7,5).
To find:
The component equation of the plane.
Solution:
The equation of plane is
![a(x-x_0)+b(y-y_0)+c(z-z_0)=0](https://tex.z-dn.net/?f=a%28x-x_0%29%2Bb%28y-y_0%29%2Bc%28z-z_0%29%3D0)
Where,
is the point on the plane and
is normal vector.
Normal vector is -2i+5j+k and plane passes through (-10,7,5). So, the equation of the plane is
![-2(x-(-10))+5(y-7)+1(z-5)=0](https://tex.z-dn.net/?f=-2%28x-%28-10%29%29%2B5%28y-7%29%2B1%28z-5%29%3D0)
![-2(x+10)+5y-35+z-5=0](https://tex.z-dn.net/?f=-2%28x%2B10%29%2B5y-35%2Bz-5%3D0)
![-2x-20+5y-35+z-5=0](https://tex.z-dn.net/?f=-2x-20%2B5y-35%2Bz-5%3D0)
![-2x+5y+z-60=0](https://tex.z-dn.net/?f=-2x%2B5y%2Bz-60%3D0)
![-2x+5y+z=60](https://tex.z-dn.net/?f=-2x%2B5y%2Bz%3D60)
Therefore, the equation of the plane is
.
The distance of the plane flies between the two cities is 1,113.75 miles
The formula for calculating the distance travelled is expressed as:
D = vt where:
v is the speed
t is the time taken
Given the following:
v = 99mi/hr
Total time taken = 5hr + 6.25hr
Total time taken = 11.25hr
Get the required distance
Distance = 99mi/hr * 11.25hr
Distance = 1,113.75miles
Hence the distance of the plane flies between the two cities is 1,113.75 miles
