1. A trapezoidal shaped park is built on a slight incline. The function for the ground elevation above sea level is
f (x, y)= x - 3y + 20 feet. What are the coordinates of the HIGHEST point in the park? (+2 points)

What are the coordinates of the HIGHEST (maximum) point and what is the value of the function at that point?

step-by-step explanation:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.

2 over 5 and 4 over 15

don’t know last one sorry
