Given 3 non-collinear points, which of the following statements are not true? There is only 1 plane that contains all 3 points. They will be contained in the same line. Any of the 3 points can be the intersection of 2 planes. Any 2 of the points defines a line entirely within the plane.


Non-collinear points are points which do not form a
straight line. Three non-collinear points create a plane therefore they are
always coplanar. Therefore the statements which are not true are:

They will be contained in the same line. 


Any of the 3 points can be the intersection of 2 planes.

A cone is a solid made from a disc, any point on that disc, and all points between them. True or False


Answer with Explanation:

Disc, is a three dimensional shape,made up of circles of different radii and is uncovered from top.Different from Bowl,which is quite deeper, do not extend far down from top.

So,to make a cone , you have to take three points on the surface of the disc such that it forms a triangular shape,and when you cut it,you will get a shape similar to cone.

So, it is a false statement, which asserts that, A cone is a solid made from a disc, any point on that disc, and all points between them.

70 POINTS!!! PLEASE HELP!!!WILL GIVE BRAINLIEST!!!!!!!!!!While it is no doubt true that literary analysis is an effective way of understanding a literary work in depth, it can be argued that analyzing a text takes away the enjoyment of reading it. Which mode of reading do you prefer, reading for pleasure without any effort at analysis or analyzing as you read? Or do you prefer some other combination of reading strategies? Explain your preference.


I prefer reading for pleasure without any effort at analysis. Reading a passage once and looking up words in a dictionary will be a way to know new words and understand the text of the passage more.

Having a literacy device sheet in hand is important to comprehend if the text passage is a metaphor, simile, hyperbole etc and that help understand complex literacy language in poetry, Shakespearean language, and in eulogy themes.

Hope this helps.

Best answer get Brainliest. 50 points. Emerson earns money from walking dogs and answering surveys. He earns $5 a week for each dog he walks and $0.10 for each survey he answers. Last week, Emerson answered 100 surveys and earned $35. Part A: Create an equation that will determine the number of dogs he walked. (3 points) Part B: Solve this equation justifying each step with an algebraic property of equality. (6 points) Part C: How many dogs did Emerson walk last week? (1 point)


Step-by-step explanation:

5x + 10 = 35 is your equation

5x = 35 – 10    bc u brought the 10 to the other side so its symbol changes

5x = 25         now were going to bring 5 to the other side to do that we have to divide both sides by 5 (same thing like the 10)

5x/5 = 25/5

x = 5

5 dogs

The side of a square measures (3x − 6) units. Part A: What is the expression that represents the area of the square? Show your work to receive full credit. (4 points) Part B: What are the degree and classification of the expression obtained in Part A? (3 points) Part C: How does Part A demonstrate the closure property for polynomials? (3 points)


A. The area of a square is given as:

A = s^2

Where s is a measure of a side of a square. s = (2 x – 5) therefore,

A = (2 x – 5)^2                  

Expanding,

A = 4 x^2 – 20 x + 25

 

B. The degree of a polynomial is the highest exponent of the variable x, in this case 2. Therefore the expression obtained in part A is of 2nd degree.

Furthermore, polynomials are classified according to the number of terms in the expression. There are 3 terms in the expression therefore it is classified as a trinomial.

 

C. The closure property demonstrates that during multiplication or division, the coefficients and power of the variables are affected while during multiplication or division, only the coefficients are affected while the power remain the same.

Consider the following pair of equations: y = –2x + 8 y = x – 1 Explain how you will solve the pair of equations by substitution. Show all the steps and write the solution in (x, y) form. (5 points)


There is a special kind of substitution which some books call it by comparison.

When the two equations are both 
y=some function of x
y=some other function of x, then
we can substitute the second equation into the first giving
some function of x = some other function of x and start solving.

For example,
y = –2x + 8 
y = x – 1
substitute second into first
x-1=-2x+8
isolate x on left,
3x=9
x=3
second step is to substitute x=3 into second equation to get
y=x-1=3-1=2
Therefore the solution is (3,2)

Look at the graph of this system of equations: y = – x2 + 1 and y = x2. At which approximate points are the two equations equal? A) (-0.7, 0.5) B) (0.5, 0.7) C) (0.7, 0.5) D) (-0.5, 0.7) Note: There can be more than answer. Help me and I will give you brainliest. Thank you. In this picture, there’s the graph.


Y=-x^2+1 and y=x^2

When the two curves intersect their coordinates will be equal, so we can say y=y whenever a solution exists, so:

x^2=-x^2+1  add x^2 to both sides

2x^2=1  divide both sides by 2

x^2=1/2  take the square root of both sides

x=±√(1/2), so there are two solutions, we can use x^2 to find the corresponding y values.

y=x^2, y=1/2 in each instance, so the two point where the curves intersect are:

(-√(1/2), 1/2) and (√(1/2), 1/2)  or if you want approximations….

(-0.7, 0.5) and (0.7, 0.5)

There are 150 marigold plants in a back yard. Each month, the number of marigold plants decreases by 15%. There are 125 sunflower plants in the back yard. Each month, 8 sunflower plants are removed. Part A: Write functions to represent the number of marigold plants and the number of sunflower plants in the back yard throughout the months. (4 points) Part B: How many marigold plants are in the back yard after 3 months? How many sunflower plants are in the back yard after the same number of months? (2 points) Part C: After approximately how many months is the number of marigold plants and the number of sunflower plants the same? Justify your answer mathematically. (4 points)


If a quantity A is decreased by 15%, it means that what is left is 85% of it.

85%A= frac{85}{100}A=0.85A

Part A.

Consider the 150 marigolds.

After the first month, 0.85*150 are left
After the second month, 0.85*0.85*150= (0.85)^{2} *150
After the third month, 0.85*0.85*0.85*150 =  (0.85)^{3}*150
.
.
so After n months,  (0.85)^{n}*150 marigolds are left.

in functional notation: M(n)=(0.85)^{n}*150 is the function which gives the number of marigolds after n months

consider the 125 sunflowers.

After 1 month, 125-8 are left
After 2 months, 125-8*2 are left
After 3 months, 125-8*3 are left
.
.
After n months, 125-8*n sunflowers are left.

In functional notation: S(n)=125-8*n is the function which gives the number of sunflowers left after n months

Part B.

M(3)=(0.85)^{3}*150=0.522*150=78 marigolds are left after 3 months.

S(3)=125-8*3=125-24=121 sunflowers are left after 3 months.

Part C.

Answer : equalizing M(n) to S(n) produces an equation which is very complicated to solve algebraically.

A much better approach is to graph both functions and see where they intersect.
 
Another approach is by trial, which gives 14 months

M(14)=(0.85)^{14}*150=15

S(14)=125-8*14=125-112=13

which are close numbers to each other.

Gymnastics and soccer since those sports are very active and involve a lot of physical cardio, soccer involves a lot of running.

Swimming and baseball are also some hard sports especially swimming since most are your muscles are used during that activity.

Hope this helps 😉
