please write a function for the points (1/3,0) (-2 3/4,0) and (0,-5) and explain the steps.
thank you!
The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).
y = -15x - 5.

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)
By simplifying the equation, we get
\(a=-15b-5\)

King High School has asked Marcy to paint some murals around the school, and Marcy is thrilled! Her mural in the main office will show a ray of sunlight breaking through storm clouds. Marcy creates the perfect gray for storm clouds. There is a proportional relationship between the number of cans of black paint, x, and the number of cans of white paint, y, Marcy mixes together. The equation that models this relationship is y=2x. How much white paint would Marcy mix with 5 cans of black paint to create storm clouds? Write your answer as a whole number or decimal.
Marcy wants 10 cans of white paints to create storm.
What is a linear equation?A Linear Equation is an equation of a line. An equation in which the highest power of the variable is always 1. An equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.
For the given situation,
The number of cans of black paint be x, and
The number of cans of white paint be y.
The equation is y = 2x.
Marcy mix 5 cans of black paint with white paint to create storm clouds.
⇒ \(y=2(5)\)
⇒ \(y=10\)
Hence we can conclude that Marcy wants 10 cans of white paints to create storm.

the circle p has a center at (0,0) and a point on the circle at (0,4) if it is dilated by a factor of 4 what is the distance of the radius for circle p
Answer:
1
Step-by-step explanation:
If the circle is dilated by a factor 4 then the radius becomes \(4\sqrt{2}\) units.
What is area?Area is the quantity that shows the extent of surface covered. Area of circle is π\(r^{2}\). where r is radius.
How to find the radius of circle?Before dilation the radius will be \(\sqrt{(0-0)^{2} +(4-0)^{2} }\)
=\(\sqrt{16}\)
=4 units.
If the circle is dilated by factor of 4 then the area will increase byπ \((4)^{2}\)=16π
Area before dilation =16π .
Area after dilation=16π+16π=32π.
π\(r^{2}\)=32π
\(r^{2}\)=32
r=\(4\sqrt{2}\)units.
Hence the distance equal to radius is 4\(\sqrt{2}\) units.

A coin is flipped at the start of every game to determine if Team A (heads) or Team B (tails) will get the ball first.

Part B: Flip a coin 14 times and record the frequency of each outcome. Determine the experimental probability of landing on heads. Please include the frequency of each outcome in your answer. (2 points)
Part C: Compare the experimental probability to the theoretical probability. (1 point)
PLEASE HELP ASAP!!!!!
Answer: 7/14 = 0.5 or 50%
Step-by-step explanation:
Part A: The theoretical probability of a fair coin landing on heads is 0.5 or 50%.
Part B:
After flipping the coin 14 times, the frequency of each outcome could be as follows:
Heads: 7
Tails: 7
The experimental probability of landing on heads is:
7/14 = 0.5 or 50%
Part C:
Comparing the experimental probability to the theoretical probability, we can see that they are the same. This is expected because the coin is fair, and therefore the probability of it landing on heads or tails should be the same. Thus, the experimental probability of landing on heads is consistent with the theoretical probability of a fair coin landing on heads.
The theoretical probability of a fair coin landing on heads is 1/2. In an experiment where the coin is flipped 14 times, if it lands on heads 7 times and tails 7 times, the experimental probability of landing on heads is 1/2. The experimental probability matches the theoretical probability.
Explanation:Part A: The theoretical probability of a fair coin landing on heads is 1/2. Since there are only two possible outcomes (heads or tails) and the coin is fair, the probability of landing on either side is equal.
Part B: To determine the experimental probability of landing on heads, you need to flip the coin 14 times and record the frequency of each outcome. Let's say the coin landed on heads 7 times and tails 7 times. The experimental probability of landing on heads is then 7/14 = 1/2.
Part C: Comparing the experimental probability (1/2) to the theoretical probability (1/2), we can see that they are the same. This means that the experimental results align with the expected results based on theoretical probability.
