What is the equation of this circle?

Mathematics
1 answer:
madreJ [45]3 years ago
3 0

Answer:

is a way to express the definition of a circle on the coordinate plane.

Step-by-step explanation:

We know that the general equation for a circle is ( x - h )^2 + ( y - k )^2 = r^2, where ( h, k ) is the center and r is the radius. So add 21 to both sides to get the constant term to the righthand side of the equation. Then complete the square for the y terms.

A spinner is divided into 10 congruent sections.Each section is labeled with a number as shown.What is the probability that the
Rufina [12.5K]

Answer:

50%

Step-by-step explanation:

The only numbers that are multiples of 2 are all even numbers. From 1 to 10 there are a total of 5 even numbers, meaning that only 5 sections are multiples of 2. Therefore, the probability of the arrow landing in a section that is labeled with a number that is a multiple of 2 would be

5/10  if we simplify this it would be 1/2 or 50%

Finally, we can say that the probability of the arrow landing on one of these sections is 50%

(5x^2 - 3x)(8x^2 + 4x)
timurjin [86]

For this case we have the following expression:

(5x ^ 2-3x) (8x ^ 2 + 4x)

To find the product, we apply distributive property that states:

(a + b) (c + d) = ac + ad + bc + bd

So:

(5x ^ 2) (8x ^ 2) + (5x ^ 2) (4x) - (3x) (8x ^ 2) - (3x) (4x) =\\40x ^ 4 + 20x ^ 3-24x ^ 3-12x ^ 2 =\\40x ^ 4-4x ^ 3-12x ^ 2

ANswer:

40x ^ 4-4x ^ 3-12x ^ 2

Which statement best describes the use of a simulation to predict the probability that two randomly chosen people will both have
laila [671]
<span>Randomly generate an integer from 1 to 7 two times, and the probability is 1/7 ^2

This is the </span><span>statement that best describes the use of a simulation to predict the probability that two randomly chosen people will both have their birthdays on a Monday.

There are 7 days in a week, so there are 7 choices but only 1 Monday. So, 1/7 is the probability that a person's birthday falls on a Monday.

1st person asked will have 1/7 probability.
2nd person asked will also have 1/7 probability

So, (1/7)</span>² is the probability that both persons will have their birthdays on a Monday.

Can someone please help me out?
neonofarm [45]

Answer:

<h2><u><em>x    </em></u><u>|</u><u><em>   f(x)</em></u></h2><h2><u>0    |    0</u></h2><h2><u>2    |    2</u></h2><h2><u>5    |    3</u></h2><h2><u>9    |    1</u></h2><h2><u>10  |    0</u></h2>

Step-by-step explanation:

On the left side of the chart, is the x values. The x values are listed on the x axis which is the horizontal line.

The right side of the chart are the y values. The y values are listed on the y axis which is the vertical line.

Knowing this, we can start

First, for all the answer that we know the x value, we need to find the number that matches on the x axis. Once we find that number, we go up or down on the y axis until we find the line.

If we know the y value, we need to find the number that matches on the y axis. Then we will go right until we find the line.

Remember - There CAN NOT be two y values for the same x value but THERE CAN BE two x values for the same y value
