The law of conservation of energy. The energy due to work performed on the skateboarder is converted into kinetic energy such that:
Work=Kinetic Energy
So 380=(1/2)(35)(7-Vo). I don’t have a calculator so..
Assumptions we made:
No energy loss, all work went into the energy of motion of the skateboarder. In the real world, this is not possible because some of the energy can be loss through friction of the skateboarder to the ground etc.
Answer:
<em>m = 1 </em>
Step-by-step explanation:
Slope = ![\frac{rise}{run} or \frac{Δy}{Δx}](https://tex.z-dn.net/?f=%5Cfrac%7Brise%7D%7Brun%7D%20%20%20or%20%5Cfrac%7B%CE%94y%7D%7B%CE%94x%7D)
-4 - 1 = -5
3 - (-2) = 5
5/5 = 1
Slope is 1
Hope this helps! :)
Answer: 3 1/10
Step-by-step explanation:
what i think
4/5+1/4 +1/4+3/5= 1.9
Exact form: 19/10
Decimal form:1.9
Mixed number form: 1 9/10
so out of the whole week he goes 3 times so then:
4/5+1/4 +1/4+3/5 x 3= 3.1
Exact form:31/10
Decimal form: 3.1
Mixed number form: 3 1/10
Answer:
h = $4 a hotdog
c = $2 bag of chips
Step-by-step explanation:
3h + c = 14
2h + c = 10
3h + c = 14
-2h - c = -10
h = $4 a hotdog
2(4) + c = 10
8 + c = 10
c = $2 bag of chips
Here the only limitation on the domain exists when the denominator is equal to zero, as division by zero has no meaning and is not "allowed" because of its meaninglessness. :)
Factor the denominator to find the excluded values of x...
3x^2+5x-12
3x^2+9x-4x-12
3x(x+3)-4(x+3)
(3x-4)(x+3)
So x CANNOT equal 4/3 or -3 (all other real values of x are part of the domain) so the domain is:
x=(-oo, -3),(-3, 4/3),(4/3, +oo)
