L 1.1.5 Quiz: Scale Drawings Question 1 of 5 What is the area of the real object that the scale drawing models? Scale factor: 1.5 Area = 12 square cm Scale drawing Object

18 cm²

Step-by-step explanation:

Based on the given information, the first object has an area of 12 cm² and the scale factor is 1.5. Since we know that, we can simply take the first area and multiply it by the scale factor:

12 · 1.5 = 18

Therefore, the second object will have an area of 18 cm².

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
