When you divide a fraction by a fraction, you're really just multiplying by a reciprocal. A reciprocal is the fraction flipped around.
So, 1/8 <span>÷ 1/4 is the same thing as 1/8 x 4/1
Now, you just multiply. 1 times 4 is 4. 8 times 1 is 8.
1/8 x 4/1=4/8
4/8 simplified is 1/2
So that is how 1/8</span><span>÷1/4=1/2</span>
Let's start with simplifying this equation. Typically we have y = something, so let's rewrite it in this form.
3xy = -3
y = -3/3x
y = -1/x
Alright! Now, let's go ahead and solve for the y-intercept. Those only occur when x=0, so let's plug in 0 for x.
y = -1/0
Slight problem. Dividing by a 0 results in an imaginary number, or "undefined". In this case, there is no y-intercept.
Now we can solve for an x-intercept. These only occur when y=0, so let's set y to 0!
0 = -1/x
Well shoot! We have another problem. No regular number of x will give us a y=0. However, this problem isn't the same as our undefined one from before. Here, as x value approach infinity, we get closer and closer to 0. We can never actually hit 0, but we do approach it. I'm not sure how your teacher wants it answered, but strictly, there is no x-intercept. However, we can actually attempt to explain what is going on, which is that as x go to infinity, we APPROACH y=0.
Hope that helps, and please let me know if you need clarification on anything!
You use the equation Final Velocity²= (Initial Velocity)² 2(Acceleration)(Distance). You plug in what you have 0²=22.4² X 2(-3.5)(D) and solve for D which is 71.68m or about 72m.
Answer:
$ 125,000
Step-by-step explanation:
Given,
The amount of rent = $ 25,000,
The salary of assistant = $ 30, 000
Expenses = $ 20,000,
Also, her best alternative is to work elsewhere and to earn a salary of $50,000 per year.
Thus, the investment in the firm = 25000 + 30000 + 20000 + 50000
= $ 125,000,
Now, if she earns zero economic profit,
Then her revenue = investment
= $ 125,000
