Considera il triangolo di vertici A (-1,0), B(1,-1) e C(2,2) a. Determina il perimetro e la sua area.
b. Stabilisci se il triangolo è rettangolo
c. Determina l’equazione della retta che contiene la mediana relativa ad AB
d. Determina l’equazione della retta che contiene l’altezza relativa ad AR

a

step-by-step explanation:

we need to see the graph to know but

strong positive is if it is going up from left to right in a straight diagonal line (like this /)

strong negative is the same but from right to left (like this \)

weak negative is the same as strong negative but its more straight line still right to left

and weak positive is the same as strong positive but more a straight line still left to right though.

well, if you graph the linear equation using intercepts or other methods, and the line is straight, then the equation is linear

1875cm³

step-by-step explanation:

we have a 20 × 20 × 5 container with (what im guessing is a) 5 × 5 × 5 hole in the center. first, we need to calculate the volume of the 20 × 20 × 5 container.

20 × 20 × 5 = 2000cm³

now, we need to calculate the volume of the hole.

5 × 5 × 5 = 125cm³

now to find the area of the container, we take to solid area of the container, and subtract the area of the hole.

2000cm³ - 125cm³ = 1875cm³
