<h3>Answer: orthocenter</h3>

Explanation:

An altitude of a triangle extends from one vertex to the opposite side, where this altitude is perpendicular to the opposite side. The term "altitude" is often interchanged with "height". Think of a tall mountain that has a lot of altitude, so it's got a lot of height.

Any triangle has 3 different altitudes (one per corner). For any triangle, those three altitudes always intersect at exactly one point: the <u>orthocenter</u>. This is one of the many centers of a triangle. Other centers are the centroid, incenter, and circumcenter.

Determine lim sin(x)/(x²-x)

spin [16.1K]

The limit of a product is equal to the product of limits:

$\displaystyle\lim_{x\to0}\frac{\sin x}{x^2-x}=\left(\lim_{x\to0}\frac{\sin x}x\right)\left(\lim_{x\to0}\frac1{x-1}\right)$

You should recognize the first limit, which has a value of 1. In the second limit, the expression $\dfrac1{x-1}$ is continuous at $x=0$ , so its value is -1, and so the overall limit has a value of 1*(-1) = -1.

Please help me answer this

prohojiy [21]

Answer:

z^11

Step-by-step explanation:

The applicable rule of exponents is ...

(a^b)(a^c) = a^(b+c)

$z^5\cdot z^6=z^{5+6}=\boxed{z^{11}}$

<em>Additional comment</em>

It might help you to think of an exponent as indicating repeated multiplication. It tells you how many times the factor is repeated. In this case, it means ...

$z^5\cdot z^6=(z\cdot z\cdot z\cdot z\cdot z)\cdot(z\cdot z\cdot z\cdot z\cdot z\cdot z)\\=z\cdot z\cdot z\cdot z\cdot z\cdot z\cdot z\cdot z\cdot z\cdot z\cdot z = z^{11}$

Find the point on the graph of 2x+3y=12 where x=3

mafiozo [28]

Answer:

(3,2)

Step-by-step explanation:

2x+3y=12

substitute x with 3 because x=3

2(3)+3y=12

multiply

6+3y=12

(subtract 6 from both sides)

3y=6

(divide by 3 on both sides)

1y=2

x = 3 and y = 2
