Answer:
4.9 × 10^24
Explanation:
^ means to the power so 4.9 × 10 to the power of 24
Answer:
Fuel 1 changed phase because the energy drawn from it dropped its temperature below the transitional temperature that causes a phase change, fuel 2 still has its temperature well above the transitional temperature required to change phase.
Explanation:
For a substance to change phase, a transitional temperature has to be reached. This is because, the temperature of substances generally indicates the average kinetic energy of its molecules. An increase in energy input to the system will result in a change to a more mobile phase like from solid to a liquid state or from a liquid state to a gaseous state state, while taking energy from the system will cause a transition to a less mobile phase like gas to liquid or liquid to solid state.
An example of basic trigonometric functions question is find tan 
.
<h3>What are trigonometric functions?</h3>
The term trigonometric function is known to be made up of functions such as sine (sin), cosine (cos), tangent (tan), etc., that stands for the ratios of sides of all right triangles.
To solve for tan
It will be = 2
+ 
θ = 
θ = 
To know the right angle,
θ = x 180/4 = 45⁰
tan θ = 1
Therefore, tan = -1

Answer:
3573.64
Explanation:
y=ab^x
a=starting value = 19000
r=rate = 11.25%=0.1125
Exponential Decay:
b=1-r=1-0.1125=0.8875
Write Exponential Function:
y=19000(0.8875)^x
Plug in time for x:
y=19000(0.8875)^14
y= 3573.6388855
Evaluate :
y≈3573.64
Answer:
There are two types of reinforcement, known as positive reinforcement and negative reinforcement; positive is where by a reward is offered on expression of the wanted behavior and negative is taking away an undesirable element in the persons environment whenever the desired behavior is achieved.
