What are the solution(s) to the quadratic equation 50 – x2 = 0?
Dmitrij [34]

Answer:

x = ±5\sqrt{2}

Step-by-step explanation:

We have been given the quadratic equation;

50-x^{2}=0

The first step is to subtract 50 from both sides of the equation;

50-x^{2}-50=0-50

-x^{2}=-50

Multiplying both sides by -1 yields;

x^{2}=50

The final step is to obtain square roots on both sides;

\sqrt{x^{2} }=\sqrt{50}\\x=+/-\sqrt{50}

Therefore, x = ±5\sqrt{2}

The projected sales volume of a video game cartridge is given by the function s(p) = 3000 / (2p + a), where s is the number of c
Alex_Xolod [135]

Answer: 149 cartridges will be sold at 20 dollars per cartridge.

Step-by-step explanation:

Given: The projected sales volume of a video game cartridge is given by the function s(p)=\dfrac{3000}{2p+a}, where <em>s</em> is the number of cartridges sold, in thousands; <em>p</em> is the price per cartridge, in dollars; and <em>a</em> is a constant.

Put s(p)=100000, p= 10, we get

100000=\dfrac{3000}{2(10)+a}\\\\\Rightarrow\ 100=\dfrac{3}{20+a}\\\\\Rightarrow\ 100(20+a)=3\\\\\Rightarrow\ 2000+100a=3\\\\\Rightarrow\ 100a=-1997\\\\\Rightarrow\ a=-19.97

i.e. s(p)=\dfrac{3000}{2p-19.97}

Put p=20, we get

s(20)=\dfrac{3000}{2(20)-19.97}\\\\=\dfrac{3000}{40-19.97}\\\\=\dfrac{3000}{20.03}\approx149

Hence, 149 cartridges will be sold at 20 dollars per cartridge.
