Renu wants to put a border of lace around a rectangular table cover 4 m long and 2 m wide..

Find the length of the lace required for the table cover..

answer: a.   one is a factor of every whole number since every number is divisible by itself.

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

hope i !

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

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
