Jackson claims that multiplication always makes a number bigger. he gave the following examples:
 if i take 6, and i multiply it by 4, i get 24, which is bigger than 6.
 if i take 1/4, and i multiply it by 2 (whole number), i get 2/4, or 1/2, which is bigger than 1/4,
jackson’s reasoning is incorrect. give an example that proves he is wrong, and explain his mistake using pictures, words, or numbers.

Explained

Step-by-step explanation:

Jackson is incorrect here because multiplication does not always makes a number bigger.

whole number when multiplied by a fraction will become smaller that its previous value also any number or fraction when multiplied with a negative number or fraction will negative m=number less than

for example 5×2 = 10 and 5×0.2 = 1 clearly 1<5

also 5×(-2) = -10 again -10<5

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
