sorry if i am asking a lot, totally suprised by this and dont know what to do and yall are great, i need to find X and Y with exact values and no decimals

x and y = 19

Step-by-step explanation:

sin 45/x = sin90/19

19×sin45=sin90x

x=19

Pythagorean theorem for y

=(19)^2 - 19^2

y^2= 722 - 361

y^2= 361

y=19

The answers seem kinda weird to me so...

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

2/3
