Answer:

(x + 1)^2 + (y - 2)^2 = 3^2 = 9

Step-by-step explanation:

The standard equation of a circle with center at (h, k) and radius r is

(x - h)^2 + (y - k)^2 = r^2.

Here, h = -1, k = 2 and r = 3, so the equation of this particular circle is

(x + 1)^2 + (y - 2)^2 = 3^2 = 9.

Sarah has a bag of 50 skittles, some are red and some are yellow. Sarah randomly pulls a skittle out of the bag and records it,
Leno4ka [110]

Answer:

20

Step-by-step explanation:

Assume n is the number of times she pick a skittle out of the bag

The probability she pick out red : 8/n

The probability she pick out yellow : 12/n

=> The ratio of red and yellow skittle : 8/n : 12/n = 8/12 = 2/3, means every 2 red skittles we have 3 yellow ones.

But we have 50 skittles, so the likely numbers of reds in the bag is = 2*\frac{50}{5} = 20

What is the domain of the functions below: b y= 5x/|x−1| −1
sdas [7]

Answer:

<h2>DOMAIN: The set of all real numbers except 0</h2>

\large\boxed{x\in\mathbb{R}-\{0\}}

Step-by-step explanation:

We have a faction.

We know: the denominator must be different from 0. Therefore

y=\dfrac{5x}{|x-1|}-1\Rightarrow |x-1|\neq0\iff x-1\neq0\iff x\neq1

The 5th out of 10 questions
seraphim [82]

In the division a/b, a is the dividend, and b is the divisor.

In this problem, 2/3 is the dividend, and 4/5 is the divisor.

She needed to multiply the dividend, 2/3, by the reciprocal of the divisor, 5/4.

Instead, she multiplied the dividend by the divisor without using the reciprocal.
