The base of the right triangular prism is an isosceles triangle with the sides 13, 13, 10, and the height of the prism is 16. Find the distance of the points A and D, if AD is an altitude of the base ABC.

but which class are u may know that first

6.25 grams

step-by-step explanation:

(a) x intercepts: -6 and 2

you can obtain these by solving the equation 0=x^2 +4x-12 using your favorite quadratic formula. but it is easy to verify -6 and 2 indeed satisfy this equation.

(b) y intercept: -12

this is obtained by setting x=0: 0^2+4*0-12 = -12

(c) the minimum value is: -16 (this is the vertex)

you can get the vertex by rewriting the equation into the form:

there is no global or local maximum as the function goes to infinity, so only in the limit sense: +infinity.
