Five less then three times the sum of a number And four is rwenty two?

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

it is 32.5

i hope i could u.

answer: ⇒ d. (7.3)(8.52)=62.19

step-by-step explanation:

product it's going to be multiply by the numbers, fractions, factors, and multiples.

1. (29.5)(1.7)=50.15

2. (13.2)(4.5)= 59.4

3. (4.67)(9.8)= 45.76

4. (7.3)(8.52)= 62.19

hope this !
