Answer:
column 1, (2 and 2)
column 2, (8 and 4)
Step-by-step explanation:
For the first one, y = 2[tex]x^{2}[/tex]. You would plug in 1 into x and since one times itself is one, you would end up with 2. For the next question, you would plug in one and find that two times one is two. For the next column, by plugging in 2, you would find that you would end up with 2 times 4 and thus, you would find the answer which is 8. Lastly, two to the power of two is 4. Hope this helped!

what number needs to be added to 7 and 9 so that the ratio of the first number to the second becomes 4:5?
Answers
Step-by-step explanation:
Let the number be x.
Now after adding 7 and 9 and taking the ratios of first and second the ratio becomes 4:5.
According to the given condition,
x+7 / x+9 = 4 / 5
5 (x+7) = 4 (x+9)
Cross multiplying both sides , we get
5x + 35 = 4x + 36
x = 1
The number obtained is 1.
The number that is added to 7 and 9 and when taken ratio gives 4:5

if u see a snake what do u do?
A. run away from it
B. run towards it
C. make loud noise
D. throw stuff at the snake
Answers
run towards it and throw stuff at it
Answer: A. run away from it
The African black mamba is the fastest moving land snake at 16-20 km/h. A person—regardless of how scared they are—could easily escape and outpace that snake with no problem. In reality, there's no need to run at all. The snake won't attack you unless you provoke it (i.e., don't do what option B, C, or D suggests), and snakes are probably more scared of us than we are of them. If I could add an option, I'd add: E. Leave it alone or keep still. If it moves towards you, slowly back off, and if it moves again, keep still, and then move slowly. The snake will eventually back off unless you do something to agitate it.

What is the value of x if AABC is equilateral?
Answers
Answer:
x= 2
Step-by-step explanation:
Given that,
AB = 7.5x
BC = 6x+3
AC = 10x-5
ΔABC is an equilateral triangle.For an equilateral triangle, all sides are equal. ATQ,
AC = BC = AB
10x-5 = 6x+3
Taking like terms together
10x-6x = 5+3
4x = 8
x = 2
Hence, the value of x is equal to 2.

The point P ( 2 , 5 ) lies on the equation of line y = 3x - 1
What is an Equation of a line?
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
y = 3x - 1 be equation (1)
Let the point be represented as P
The coordinates of P is = P ( 2 , 5 )
Substituting the values of x and y in the equation , we get
y = 3x - 1
when x = 2 and y = 5 , we get
5 = 3 ( 2 ) - 1
5 = 6 - 1
5 = 5
Therefore , the solution is true
Hence , the point P ( 2 , 5 ) lies on the equation of line

Im not sure about 2 but i think its welsh corgis
3. (Im also not sure about this one, so dont take my word for it if my answer doesnt seem right) I think the heaviest dog is the welsh corgi bc i added all the weights together for the welsh corgis.
Step-by-step explanation:
According to the table the median of Welsh Corgi is 27.3kg whereas the Welsh Corgi has the maximum variation in weights.
What is the median?The median is the center most value of the data.
What is mean absolute deviation?It is the distance of value from the average mean.
How to answer?1) When we see table we can easily find that the median of Welsh Corgi is 27.3 kg and median tells us about the center level of all the weights.
2)Welsh Corgi has the greater variation in weights because its range is higher than Cocker Spaniel.
3) No, because average weight of both the type of dogs is equal.

15. Find the coordinates of D, the midpoint of AB.
16. Find the length of the median CD.
17. Find the coordinates of the centroid. Label this point as G.
Answers
Answer:
Step-by-step explanation:
15) point D=(3,1)
for AB we can see that there is an exact triangle of 2 and 5
so AD = [tex]\sqrt{2^{2} +5^{2} }[/tex] = [tex]\sqrt{29}[/tex] and 2(AD) = AB
AB = 2*[tex]\sqrt{29}[/tex] ( this is an exact answer, leave it with the square root)
16) find CD length we know the points at each end so use the distance formula P1=(-3,4) P2=(3,1)
Dist. = [tex]\sqrt{(3-(-3))^{2} +(1-4)^{2} }[/tex]
Dist. =[tex]\sqrt{45}[/tex] = [tex]\sqrt{9*5}[/tex] = 3[tex]\sqrt{5}[/tex] ( exact answer leave the square root )
CD = 3[tex]\sqrt{5}[/tex]
17) 1/3 of the way along CD from D towards C is where the centroid is.. I just happen to know that from doing this too often. :/
so that mean [tex]\frac{1}{3}[/tex] * [tex]3\sqrt{5}[/tex] is the distance from D to the centroid or [tex]\sqrt{5}[/tex]
also b/c I happen to know.. :/ c = [tex]\sqrt{1^{2}+ 2^{2} }[/tex] = [tex]\sqrt{5}[/tex] off the top of my head I can see that the point (1,2) is our centroid for this object.. they made it really easy ... okay.. relatively easy. .:D
Centroid = (1,2)
