Answer:
A (6. 1) C (2. -7)
6-2 = 4 1- (-7) = 8
as AB= 1/3 BC = AB= 1/4 AC
so x=6-4/4 =5
y= 1-8/4 =-1
so B(5, 1)
Answer:
B(5, - 1)----------------------------------
GivenPoints A(6, 1) and C(2,- 7),Point B that partitions AC as AB : BC = 1 : 3.Find point BUse the section formula
[tex]P=(\dfrac{mx_2+nx_1}{m+n} ,\dfrac{my_2+ny_1}{m+n} )[/tex], where P- point to be found, m : n is the ratio and the (x,y) are coordinates of endpointsSubstitute and find the point B:
[tex]B=(\dfrac{1*2+3*6}{1+3} ,\dfrac{1*(-7)+3*1}{1+3} )=(20/4,-4/4)=(5,-1)[/tex]in your own words state the segment addition postulate.
see the attached figure
the points A, B and C are collinear (the three points lies on the same line)
so
AC=AB+BC ------> by addition segment postulate

The △ABC is congruent to triangle △ADE (△ABC ≅ △ADE) under (B) SAS condition.
What do we mean by the congruency of triangles?Two triangles are said to be congruent if all three corresponding sides and all three corresponding angles have the same size.
You can move, flip, twist, and turn these triangles to produce the same effect.
So, first label the two triangles as △ABC and △ADE.
Now, to prove that △ABC ≅ △ADE:
BA = DA (Given)
AC = ED (Given)
∠BAC = ∠ADE (Since, both lines are similar, so the angle between them will also be soililar and congruent.
So, we can say that △ABC ≅ △ADE is under SAS conditions.
Therefore, the △ABC is congruent to triangle △ADE (△ABC ≅ △ADE) under (B) SAS condition.

-2/3 (x-7) = 1/6 (x+1) -3
Answer: x = 9
Step-by-step explanation:
We will isolate the variable x to solve this equation.
Given:
-2/3 (x-7) = 1/6 (x+1) -3
Distribute:
-2/3x + 14/3 = 1/6 (x+1) -3
-2/3x + 14/3 = 1/6x + 1/6 -3
Combine like terms on the right side using subtraction:
-2/3x + 14/3 = 1/6x - 17/6
Subtract 1/6x from both sides of the equation:
-5/6x + 14/3 = - 17/6
Subtract 14/3 from both sides of the equation:
-5/6x = -15/2
Divide both sides of the equation by -5/6:
x = 9

The product of the ages (in days) of two newborn babies Simran and Jessie in two dayswill be 48 more than the product of their ages today. How old are the babies if Jessie is 2days older than Simran?
Given that:
- The product of the ages (in days) of babies Simran and Jessie in two days
will be 48 more than the product of their ages today.
- Jessie is 2 days older than Simran.
Let be "j" Jessie's age (in days) and "s" Simran's age (in days).

ANSWER and EXPLANATION
We want to order the functions from widest to narrowest:
[tex]\begin{gathered} y=3x^2 \\ y=2x^2 \\ y=4x^2 \end{gathered}[/tex]To do this, we have to plot the graphs of the functions by using a table of values.
Let us find the values of the functions for values of x = -2, 0, 2
For the first function:
[tex]\begin{gathered} y=3x^2 \\ \Rightarrow x=-2: \\ y=3(-2)^2=3*4 \\ y=12 \\ \Rightarrow x=0: \\ y=3(0)^2=3*0 \\ y=0 \\ \Rightarrow x=2: \\ y=3(2)^2=3*4 \\ y=12 \end{gathered}[/tex]Hence, its table is:
For the second function:
[tex]\begin{gathered} y=2x^2 \\ \Rightarrow x=-2: \\ y=2(-2)^2=2*4 \\ y=8 \\ \Rightarrow x=0: \\ y=2(0)^2=2*0 \\ y=0 \\ \Rightarrow x=2: \\ y=2(2)^2=2*4 \\ y=8 \end{gathered}[/tex]Hence, its table is:
For the third function:
[tex]\begin{gathered} y=4x^2 \\ \Rightarrow x=-2: \\ y=4\left(-2\right)^2=4*4 \\ y=16 \\ \Rightarrow x=0: \\ y=4(0)^2=4*0 \\ y=0 \\ \Rightarrow x=2: \\ y=4(2)^2=4*4 \\ y=16 \end{gathered}[/tex]Hence, its table is:
Now, let us plot the graphs of the functions:

how much must be deposited at the beginning of every six months in an account that pays 6% compounded semi-annually so that the account will contain 35,000 at the end of five years the semi-annual payments are___?round to 2 decimal places

[tex]I=P(1+\frac{r}{n})^{nt}[/tex]where:
P: initial investment = ?
r: interest rate = 6% = 0.06

based on this relationship which could be the correlation coefficient?
Based on the relationship in the given table the correlation coefficient is -0.9985 .
Let us define a few variables first.
X: X Values
Y: Y Values
Mx: Mean of X Values
My: Mean of Y Values
Deviation scores = X - Mx , Y - My
Deviation Squared = variance = (X - Mx)² , (Y - My)²
Product of Deviation Scores = (X - Mx)(Y - My):
Now we will use the defined variables to calculate the correlation coefficient
X Values
∑ = 118.5
Mean = 11.85
∑(X - Mx)² = Sx = 1283.705
Y Values
∑ = 206
Mean = 20.6
∑(Y - My)² = Sy = 16804.4
X and Y Combined
N = 10
∑(X - Mx)(Y - My) = -4637.7
R Calculation
r = ∑((X - My)(Y - Mx)) / √((Sx)(Sy))
r = -4637.7 / √((1283.705)(16804.4)) = -0.9985
The correlation coefficient is the only statistical measure of the given strength of a linear relationship that is amongst the two variables. Its values normally range from -1 to 1.
Based on a correlation coefficient of 1, which indicates a completely negative or inverse relationship, values in one series increase as those in the other decline, and vice versa.
Hence the correlation coefficient is -0.9985

Step-by-step explanation:
3. In the figure below, XU is the midsegment of TVW and is parallel to VW, determine the length of XU. (3 points) 11x + 2 U 10x + 16
If XU is the midsegment of TVW, then, it is necessary that:
(11x + 2)/(10x + 16) = 1/2
multiply the previous equation by 10x + 16:
11x + 2 = 1/2(10x + 16)
11x + 2 = 5x + 8 subtract 5x and 2 both sides
11x - 5x = 8 - 2
6x = 6
x = 6/6
x = 1
THe length of XU is:
XU = 11x + 2 = 11(1) + 2
