Step-by-step explanation:
x-intercept => point (2, 0)
y-intercept => point (0, -4)
Answer:
F, I only
Step-by-step explanation:
We can see this is a quadratic equation and c is the constant. What changes when we change the constant? It will change the h intercept which we can see is also known as a y intercept (the y axis is renamed as h).
You can also use graphs to visualize this, try changing the constant in the equation and you can see the y intercept change.
so the answer is F, I only.
Answer:

So it would takes approximately 6.9 hours to reach 32 F.
Step-by-step explanation:
For this case we have the following differential equationÑ

We can reorder the expression like this:

We can use the substitution
and
so then we have:

IF we integrate both sides we got:

If we apply exponential in both sides we got:

And if we replace w = u-T we got:

We can also express the solution in the following terms:

For this case we know that
since w ehave a cooloing,
, we have this model:
And if we want that the temperature would be 32F we can solve for t like this:



If we apply natural logs on both sides we got:


So it would takes approximately 6.9 hours to reach 32 F.
Answer:
13.187 meters
Step-by-step explanation:
Basically, there are 24 meters for every 91 steps: 
There are x meters for every 50 steps: 

Cross multiply
91x = 1200
Divide both sides by 91 to isolate the variable, x
91x/91 = 1200/91
x = 13.186813
