To the nearest hundredth, how many cm are in 60 in? (1 in = 2.54 cm)
a) 122.54 cm
b) 147.40 cm
c) 152.40 cm
d) 162.40 cm

i'm giving 14 points for best answer

C (152.40)

Step-by-step explanation: 2.54 x 60=152.40cm

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
