Consider equations of the form x - a= sqrt(bx+c) , where a, b, and c are all positive integers and b > 1. (a) Create an equation of this form that has 7 as a solution and an extraneous solution. Give the extraneous solution.
(b) What must be true about the value of bx+c to ensure that there is a real number solution to the equation? Explain.

Only answer if you can explain this to me correctly. Do not answer for points please.

linearly: 8560 bacteria

exponentially: approximately 75233 bacteria

step-by-step explanation:

assuming it is not exponential (we would have some really complicated logarithms), let's say it is linear. then, after 5 hours, it increased by 1200 bacteria, so every hour it increases by 240 bacteria. this means that after 19 hours, we get 19 * 240 + 4000 bacteria or 3800 + 760 + 4000 = 7800 + 760 = 8560 bacteria.

because it says round your answer, i will do this exponentially (with a calculator, of course). first, we need to find how much it multiplies by every hour, by taking the 5th root of 52/40 or 13/10. this is approximately 0.167. we still need to add 1 to this, because we are multiplying by that number, not adding that amount of the number. now, we just calculate 4000 * (1.167)^19. use a calculator to get approximately 75232.6, or 75233.
