I think its C im not sure if im right though.
energy is always transformed from one form to another
energy is not created nor destroyed
so when a car starts moving the chemical potential energy of the car is converted to kinetic energy
kinetic energy is the energy that moving objects possess
kinetic energy formula is as follows
Kinetic energy = 1/2 mv²
where m - mass
v - velocity
substituting these values
K.E = 1/2 x 1350 kg x (12 m/s)²
= 1/2 x 1350 x 144 = 97200 J
the kinetic energy of the car is 97.2 kJ
Answer:
x = -84, y = -58
Step-by-step explanation:
2x - 3y = 6 --- Equation 1
Equation 1×5: <em>10x</em> - 15y = 30 --- Equation 2
5x + 7y = -14 --- Equation 3
Equation 3×2: <em>10x</em> + 14y = -28 --- Equation 4
<u>I will eliminate 10x. </u>
Equation 4-2:
10x - 15y - 10x + 14y = 30-(-28)
-y = 30+28
= 58
y = -58
Substitute y =-58 into Equation 1.
2x - 3y = 6
2x - 3(-58) = 6
2x - (-174) = 6
2x + 174 = 6
Find 2x.
2x = 6-174
= -168
Find x.
x = -168 ÷ 2
x = -84
Answer:
the perimeter is 10.99 units.
Step-by-step explanation:
We have a triangle with points in:
X // Y
N 2 // 0
P -1 // -2
M 4 // 0
We can solve for the side of the triangle by subtracting the points to calculate the distance between them, AKA the side of the triangle.
M - N = NM = 4 - 2 = 2 units of X
M - N = NM = 0 - 0 = 0 units of Y
This has a length of 2 units of X and 0 units of Y thus, we already have a line of size 2.
Next side:
N - P = 2 -(-1) = 3 units of x
N - P = 0 - (-2) = 2 units of Y
We have a length of 3 units of X and 2 of Y we use Pythagoras to get the length of NP:
Now, we do the same with MP:
M - P = 4 - (-1) = 5 units of X
M - P = 0 - (-2) = 2 units of Y
we solve for MP
We now add up:
Answer:
25% or 0.25
Explanation:
Based on the given conditions, formulate: 2 divided by 8
Reduce the fraction: 1/4
get the result: 25% or 0.25
Answer: 25% or 0.25
