I could really use some help! I'm stressing on the quiz and forgot paper. A right triangle has legs measuring 4.5 meters and 1.5 meters. The lengths of the legs of a second triangle are proportional to the lengths of the legs of the first triangle. Which could be the lengths of the legs of the second triangle?
Select each correct pair of lengths.
6 m and 2 m

8 m and 5 m

7 m and 3.5 m

7 m and 2.5

11.25 m and 3.75 m

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)

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
