To solve the problem shown bove you must apply the proccedure shown below:

 1. You have that:

 2a-1<<span>7−1.2a
 2a+1.2a<7+1
 3.2a<8
 a<8/3.2
 a<2.5

 2. Therefore, f</span><span>or what values of a is the value of the binomial 2a−1 smaller than the value of the binomial 7−1.2a?
</span><span>
 As you can see above, the answer for this question is:

 All the values of a between -</span>∞ and 2.5<span>
</span>

I actually got this answer from the other guy who answered here : Carlosego.

He had the right answer but thought about it too much and added some extra information that lead the answer off track. If you went back to what "a" is, you would get a<2.5.

Then, find the are or the two shapes using the area formula for a semicircle (\frac{ \pi r^{2} }{2}) and the are formula for a rectangle (base x height)
Finally, add the two areas together and you have your answer

A car with an initial cost of $26,500 depreciates at a rate of 7.5% per year. Write the function that models this situation. The
solniwko [45]

Answer:

f(x) = 26500 * (0.925)^x

It will take 7 years

Step-by-step explanation:

A car with an initial cost of $26,500 depreciates at a rate of 7.5% per year. Write the function that models this situation. Then use your formula to determine when the value of the car will be $15,000 to the nearest year.

To find the formula we will use this formula: f(x) = a * b^x. A is our initial value which in this case is $26500. B is how much the value is increasing or decreasing. In this case it is decreasing by 7.5% per year. Since the car value is decreasing we will subtract 0.075 from 1. This will result in the formula being f(x) = 26500 * (0.925)^x. Now to find the value of the car to the nearest year of when the car will be 15000 we plug 15000 into f(x). 15000 = 26500 * (0.925)^x. First we divide both side by 26500 which will make the equation: 0.56603773584=(0.925)^x. Then we will root 0.56603773584 by 0.925. This will result in x being 7.29968 which is approximately 7 years.
