1 answer:

6 0

Theorem — a mathematical statement that is proved using rigorous mathematical reasoning. In a mathematical paper, the term theorem is often reserved for the most important results.

Postulate — a statement that is assumed to be true without proof. These are the basic building blocks from which all theorems are proved

Na função y = x² - 2x +1, temos que a = 1, b = -2 e c = 1, calcule as coordenadas do vértice da parábola

MrRissso [65]

Answer:

(1, 0)

Step-by-step explanation:

x = -b / 2a

x = 2 / 2(1)

x = 2 / 2

x = 1

y = x^2 - 2x + 1

y = (1)^2 - 2(1) + 1

y = 1 - 2 + 1

y = -1 + 1

y = 0

vértice: (1, 0)

a trapezoid with base measure of 23 km and 29km an area of 390km . find the height of the trapezoid.

cupoosta [38]

Hello!

To find the area of a trapezoid you use the equation

$A = \frac{a+b}{2} h$

Put in the values you know

$390 = \frac{23+29}{2} h$

Add

$390 = \frac{52}{2} h$

Divide

$390 = 26 * h$

Divide both sides by 26

15 = h

The answer is 15km

Hope this helps!
