a) Find the center-radius form of the equation of the circle with center (0,0) and
radius 16.
Answer:
x^2+y^2=256
Step-by-step explanation:
The general formula for a circle is (x - h)^2 + (y - k)^2 = r^2; where (h , k).
Thus, (x - 0)^2 + (y - 0)^2 = (16)^2 is x^2 + y^2 = 256

Let A, B, C, X be sets with A, B, and C are subsets of X. Prove the following set equalities
a) (A ∩ B)' = A' ∪ B'
Answer:
[tex] let \:x \in (A\cap B)'\\\Rightarrow x \notin (A\cap B) \\\Rightarrow x \notin A \:or\: x\notin B\\ \Rightarrow x \in A' \:or \:x \in B'\\\Rightarrow x \in A' \cup B'\\\therefore (A ∩ B)' = A' ∪ B' [/tex]
It is proved that , A Intersection B complement is equal to the union of the complements of the sets A and B i.e., (A ∩ B)' = A' ∪ B'.
What is a set ?
Sets are represented as a collection of well-defined objects or elements.
It is given that A , B , C , X are sets with A , B and C are subsets of X.
Let's assume X be an element of A intersection B complement. or (A ∩ B)'.
i.e.,
X ∈ (A ∩ B)'
Also , we can say that :
X ∉ ( A ∩ B)
This implies :
X ∉ A or X ∉ B
or we can also say that :
X ∈ A' or X ∈ B'
or
X ∈ A' ∪ B'
So , we can conclude that :
(A ∩ B)' = A' ∪ B'
or A Intersection B complement is equal to the union of the complements of the sets A and B.
Therefore , it is proved that , A Intersection B complement is equal to the union of the complements of the sets A and B i.e., (A ∩ B)' = A' ∪ B'.

On Wednesday, each person who received an email on Tuesday sent an email to 5 different friends. How many friends received an email on Wednesday? Enter your answer as a power by filling in the boxes.
Answer:
5 to the power of 3
Step-by-step explanation:
I took the K12 test :)
The number of friends who received an email on Wednesday can be obtained using the exponential relation between the initial number of mails and the number of days elapsed, which is 125 .
The initial number of friends who received an email = 5 friends. Number of days elapsed from Monday to Wednesday = 3 daysThe Number of people who received a mail on Wednesday can be expressed thus :
5³ = 5 × 5 × 5 = 125 friends.Therefore, 125 friends received an email on Wednesday.

First calculate the Subsets for set, then calculate the number of proper subsets {10,19,5,0}
The subsets of {10, 19, 5, 0} are
{ } - the empty set, or 1 subset of size 0
{10}, {19}, {5}, {0} - 4 subsets of size 1
{10, 19}, {10, 5}, {10, 0}, {19, 5}, {19, 0}, {5, 0} - 6 subsets of size 2
{10, 19, 5}, {10, 19, 0}, {10, 5, 0}, {19, 5, 0} - 4 subsets of size 3
{10, 19, 5, 0} - 1 subset of size 4
A proper subset of a set is any subset of that set that is not equal to that set. The only subset that is not a proper subset is {10, 19, 5, 0}, since that's the set itself. So there are 15 proper subsets.
In general, a set of size n has a total of 2ⁿ subsets, and 2ⁿ - 1 proper subsets.

Solve the inequality: x+10>2x/5. *
Hello BATAPAAKO!
[tex] \huge \boxed{\mathbb{QUESTION} \downarrow}[/tex]
Solve the inequality: x+10>2x/5.
[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]
[tex]x + 10 \gt \frac { 2 x } { 5 } \\ [/tex]
Firstly, multiply both sides of the equation by 5.
[tex]5(x + 10) > 2x \\ = 5x + 50 > 2x[/tex]
Since 5 is greater than 0, the direction of the inequality will remain unchanged. Now, subtract 2x from both the sides.
[tex]5x + 50 > 20 \\ = 5x + 50 - 2x > 0[/tex]
Combine 5x & -2x to get 3x.
[tex]5x + 50 - 2x > 0 \\ = 5x - 2x + 50 > 0 \\ = 3x + 50 > 0[/tex]
Now, subtract 50 from both the sides. Remember :- anything subtracted by 0 will result in its negation. So 50 subtracted from 0 will give you -50.
[tex]3x + 50 > 0 \\ = 3x > - 50[/tex]
Divide both sides of the equation by 3. Again, since 3 is > 0, the direction of inequality will remain unchanged.
[tex]3x > - 50 \\ = \large\boxed{\boxed{ \bf \: x > - \frac{ 50}{3} }}[/tex]

What is the equation of the line in slope intercept form write your answer using integers, proper fractions, and improper tractions in simplest form
Answer:
y = 2x - 1
Step-by-step explanation:
To find out the equation of the line, you will always need the following information in order to determine the linear equation in slope-intercept form, y = mx + b:
1. 2 sets of ordered pairs (x, y)
2. Slope (m)
3. Y-intercept (b)
First, we need to choose 2 points from the graph to solve for the slope:
Let (x1, y1) = (0, -1)
(x2, y2) = (3, 5)
Substitute these values into the following slope formula:
[tex]m = \frac{y2 - y1}{x2 - x1} = \frac{5 - (-1)}{3 - 0} = \frac{5 + 1}{3} = \frac{6}{3} = 2[/tex]
Therefore, the slope (m) = 2.
Next, we need the y-intercept, (b). The y-intercept is the y-coordinate of the point where the graph of the linear equation crosses the y-axis. The y-intercept is also the value of y when x = 0. The y-coordinate of the point (0, -1) is the y-intercept. Hence, the y-intercept (b) = -1.
Given our slope, m = 2, and the y-intercept (b) = -1, the linear equation is:
y = 2x - 1
