Answer:
35 hours
Step-by-step explanation:
First 435-120 to see how much you need to earn which is 315. Then divide that by 9 which is 35 repeating.
Step-by-step explanation:
Using the Intermediate Value Theorem, the following is applied:
"If f(x) is a continuous on interval [a,b] and we have two points f(a) and f(b) then there must be some value c such that f(a)<f(c)<f(b).
So here there must be a c such that
![f(0) < f(c) < f(1)](https://tex.z-dn.net/?f=f%280%29%20%3C%20f%28c%29%20%3C%20f%281%29)
Note: F(c)=0, the questions that the function have a solution between 0 and 1, so that means we must have some value, c such that f(c)=0 that exists
Next, plug in the x values into the function
![f(0) = - 4](https://tex.z-dn.net/?f=f%280%29%20%20%3D%20%20-%204)
![f(1) = {1}^{3} + 7(1) - 4 = 4](https://tex.z-dn.net/?f=f%281%29%20%3D%20%20%7B1%7D%5E%7B3%7D%20%20%2B%207%281%29%20-%204%20%3D%204)
Since cubic functions are continuous and -4<0<4, then there is a solution c that lies between f(0) and f(1)
13 gallons in 14 minutes. The unit rate is..
.921 gallons in a minute. if your multiplying by 4. that would equal 3.684. which is rounded to 3 gallons.
Answer:
I would be 7 gallons used and 5 gallons left
Step-by-step explanation:
multyply 1.75 times 4 hours equal 7 then 12-7=5 is the total of gallons left
Hope this helps
The units of the initial and final rates of speed are;
<u><em>Initial rate of Speed = ft/hr</em></u>
<u><em>Final rate of speed = mi/min</em></u>
- We are told that the conversion factors he used are;
5280 ft/1 mi and 1 hr/60 min
- Now, the meaning of 5280 ft/1 mi denotes that;
5280 ft mile is equivalent to 1 mile
This means that the initial distance <em>unit </em>used was ft while the final one was mile
Also, 1 hr/60 min denotes that;
1 hour is equivalent to 60 minutes.
This means that the initial time units used was hour while the final one was minute.
- In conclusion, since we know the initial time and distance units used, we can say that the initial rate of speed ft/hr while final speed rate was miles/minutes.
