Suppose the expected value for the length of a meter stick is exactly one meter. A lab group checked the length of their meter stick and made the following measurements: 0.995 m, 0.998 m, 1.001 m, 1.000 m, 0.999 m Which answer choice BEST describes these measurements? A. accurate and precise B. inaccurate and precise C. accurate and imprecise D. inaccurate and imprecise

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

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

it would be 3 ÷by 6 because the number on each side

the correct answer is c

good luck love
