I REALLY NEED THIS DONE FAST please someone help me only the highlighted

2. 66

4. d/19

6. 35r+70

8. 4

10. d/16

Step-by-step explanation:

d=rt, r=d/t, t=d/r

2. r=d/t=(132)/2=66

4. t=d/r=d/19

6. d=rt=(35)(r+2)=35r+(35)(2)=35r+70

8. t=d/r=

10. r=d/t=d/16

you divide the cost ($15) by the quantity (6) to get your questions answer. the yo-yo costs $2.50. hope this : )!

step-by-step explanation:

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
