The triangle ABC is a right angled triangle.

Explanation:

Given that the coordinates of the triangle ABC

The coordinates are A(-2,4), B(2,0) and C(5,2)

We need to determine the angle for the triangle ABC

Let us plot the coordinates in the graph and join them.

From the graph, it is obvious that in the triangle ABC, at angle B the triangle forms an angle 90°

Hence, the angle formed by the triangle ABC is right angled triangle.

Therefore, ABC is a right angled triangle.

sveticcg [70]

Answer:

\frac{x}{y}=1.3

Step-by-step explanation:

<u>Informação recuperada:</u>

(UFRGS) Se 10x = 20y , atribuindo 0,3 para log 2 , então o valor de x/y é

1) Primeiro, passando o 10 para o 2º membro como base do logaritmo:

10x=20y \Rightarrow x=log_{10}20y

2) Aplicando a propriedade do produto de logaritmo:

log(AB)= logA+logB

x=log_{10}20y \Rightarrow x=log(2+10)y\Rightarrow x=(0.3+1)y \Rightarrow x=1.3y

3)  Como quero o quociente divido ambos os lados por y

\frac{x}{y}=\frac{1.3y}{y}\Rightarrow \frac{x}{y}=1.3

If y = -x² + 14x + 7 , then x = 10 is a counterexample for which conjecture?
Misha Larkins [42]

Answer:

The correct answer is B

Step-by-step explanation:

If we plug in x=10 to the equation, we get y=47

Since y is positive, A is not an counterexample

Since y is a function of x, C is not an counterexample

Since the graph of y is a parabola, D is not an counterexample

Hope this helped and mark as brainliest!
