Answer:

RPM 1388.889

Horsepower 366.802

Step-by-step explanation:

We do not need to solve the equation for y = 0, which is nice. We can go directly to finding the maximum.

The maximum or minimum of ax^2+bx+c is always at x=-b/2a

with b = 25/45 and a = -1/5000 we get

x = -25/45 / (-2/5000) = 5/9 * 2500 = 12500/9 ≈ 1388.889

Now we only need to put that x into the equation (ideally in form of 12500/9 for accuracy) and we get the horsepower of ~366.802

What is the 100th term in the list?1017243138

Studentka2010 [4]

the sequence starts at 10 and increases by 7 each time, thefore a possible sequence identification is:

$\begin{gathered} a_n=7n+3 \\ \text{Let's verify:} \\ a_1=7(1)+3=7+3=10 \\ a_2=7(2)+3=14+3=17 \\ a_3=7(3)+3=21+3=24 \\ \text{and so on} \\ \text{.} \\ \text{.} \\ \text{.} \end{gathered}$

Therefore, the 100th term is:

$a_{100}=7(100)+3=700+3=703$

Julien's parents want $64,000 at the end of 3 years. They put their money in an account that yields 10% per year compounded mont

Leto [7]

Answer: $\$47,471$

Step-by-step explanation:

Given

Julien's parents want $64,000 at the end of 3 years

The rate of interest is 10% annually

Suppose they invested P amount initially

So, compound interest, compounded monthly is

$\Rightarrow A=P\left( 1+\frac{r}{n}\right)^{nt}\quad [\text{n=Numner of compounding periods}]\\\\\text{Insert the values}\\\Rightarrow 64,000=P\left( 1+\frac{0.10}{12}\right)^{12\times 3}\\\\\Rightarrow 64,000=P\left( 1+\frac{10}{12}\right)^{36}\\\\\Rightarrow P=\dfrac{64000}{1.3481}\\\\\Rightarrow P=\$\ 47,471.37\approx \$ 47,471$
