Reese is selling lemonade at the parade. He gets to keep 50% of the money he collects. A large lemonade is $8.00 and a small lemonade is $2.00. The expression represents 50% of the money he collects.

0.50(8l + 2s)

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.

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

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
