Exponential writing assignment

lex "jc" luthor is tired of his long-time fiend superman. jc has decided that he is going to take him out with kryptonite, so jc has been using his money to grow the awesome green material jc knows that to destroy superman he will need to have at least 300 tons of kryptonite . he started with 50 tons of kryptonite, and it is growing at a continuous rate. he knows that in 3 weeks, he will have 100 tons of kryptonite

1-what is the growth rate (round to 3 decimals)?

2-how long will jc have to wait until he has enough to take out superman (round to 3 decimals)?

3-write about the key features (domain, range, growth/decay, y-intercept, end behavior, asymptotes, and increasing/decreasing behavior) and how you found them and or came this conclusion

don't forget to answer the two questions and how you calculated those answers

  the correct choice is marked

step-by-step explanation:

the first two graphs show multiple turning points. the last graphs matches the description in every detail.

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
