Answer:
The number 10/2 = 5 is an integer.
Step-by-step explanation:
An integer is a whole number which cannot be expressed in fractions. For example, 1, 2, 3...
Integer can be positive, negative of zero.
![\frac{10}{2}=5](https://tex.z-dn.net/?f=%5Cfrac%7B10%7D%7B2%7D%3D5)
It is a whole number so it is an integer.
- 0.3
It is not an integer as it has a fractional part.
![\sqrt20](https://tex.z-dn.net/?f=%5Csqrt20)
It also has a fractional part, so it is not an integer.
0.4
It also has a fractional part, so it is not an integer.
Answer: b.) the ball in box a has less kinetic energy than the ball in box b.
Step-by-step explanation:
Answer:
![(y-1)=\frac{1}{3}(x-6)](https://tex.z-dn.net/?f=%28y-1%29%3D%5Cfrac%7B1%7D%7B3%7D%28x-6%29)
Step-by-step explanation:
The equation of the line in point-slope form is:
![(y-y_1)=m(x-x_1)](https://tex.z-dn.net/?f=%28y-y_1%29%3Dm%28x-x_1%29)
Where m is the slope and
is a point of the line.
The slopes of two perpendicular lines are opposite reciprocal, then the other slope is:
m=![\frac{1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D)
Substitute the slope and the given point into the equation, then you obtain:
![(y-1)=\frac{1}{3}(x-6)](https://tex.z-dn.net/?f=%28y-1%29%3D%5Cfrac%7B1%7D%7B3%7D%28x-6%29)
