The area of a square poster is 31 in squared. find the length of one side of the poster to the nearest tenth of an inch.

Since, area of square poster = 31 square inches.

We have to determine the length of one side of the poster to the nearest tenth of an inch.

Area of square with side 's' =

So,

s = 5.56

Now, rounding to the nearest tenth, we get the side of the square poster as 5.6 inches.

Therefore, the length of one side of the poster is 5.6 inches.

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

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
