A point K is on the perpendicular bisector of a segment with endpoints at H and J. What must be true about point K? It is equidistant from H and J It falls on the h j It is at the midpoint of h j Not enough information is given
Answer:
[tex]K[/tex] is equidistant from [tex]H[/tex] and [tex]J[/tex].
Step-by-step explanation:
Given that the point [tex]K[/tex] which is on the perpendicular bisector of the line segment having endpoints at [tex]H[/tex] and [tex]J[/tex].
The given situation can be represented as the diagram as attached in the answer area.
Referring to the [tex]\triangle HOK, \triangle JOK[/tex]:
[tex]\angle HOK = \angle JOK=90^\circ[/tex] (As it is the perpendicular bisector)
[tex]OH = OJ[/tex] (As it is the perpendicular bisector)
Also, the side [tex]OK[/tex] is the common side.
Therefore by [tex]S-A-S[/tex] congruence, [tex]\triangle HKO\cong \triangle JKO[/tex]
As per the properties of congruent triangles:
Side [tex]HK[/tex] = Side [tex]JK[/tex]
[tex]HK[/tex] and [tex]JK[/tex] are nothing but the distance of the point [tex]K[/tex] from the end points [tex]H[/tex] and [tex]J[/tex] which are proved to be equal to each other.
Therefore, we can conclude that:
[tex]K[/tex] is equidistant from [tex]H[/tex] and [tex]J[/tex].

what is the 16th term in a sequence 11, 0, -11, -22
Answer:
-154
Step-by-step explanation:
The formula for the sequence is: an = -11n + 22
If n equals 1 you get the first term, and so on.
For the 16th term n=16.
-11(16) + 22
-176 + 22

A number tripled then increased by -2 is thirteen
pls I need the equation, not the answer
Answer:
3n - 2 = 13
Step-by-step explanation:
A number tripled would represent a number times 3, so it would be "3n"
If it is increased by -2, then you would be adding -2, or subtracting by 2
lastly, you put " = 13" because "is" in an equation also means "equals"
write the equation of the line that passes through the point (2,-3) and is perpendicular to the line y=-2x+3. And how do you find it?
Answer:
y=2x-7
Step-by-step explanation:
The easiest way to answer this would be by using the slope-intercept form equation, y=mx+b. In this case, we can use our given in information to plug in values and find the equation.
Firstly, let's assess what know and what we don't:
Given the point (2,-3), we know that x=2 and y=-3. Now the slope for a perpendicular line can be found using a negative reciprocal, since the product of the slopes of both lines should equal -1. Therefore the slope must be 2.
All that's left is b, the y-intercept. To solve for this, we simply plug in what we have.
y=mx+b
-3=2(2)+b
-3=4+b
-3-4=b
-7=b
Now that we have b, we can write the equation:
y=2x-7
Today the school's math club has $75 in its account. Yesterday the club members spent $27.75 on fees to enter a competition. The equation 75=a-27.7575=a−27.75 represents this situation. What does the variable : a represent in this situation?
Answer:
a represents the amount of money that the math club had yesterday in its account.
Step-by-step explanation:
the account currently has $75.Yesterday, they spent $27.75 in fee to enter a competition, so that means that before they paid the fees, the math club's account had $75 + $27.75 = $102.75

The number of times that interest is compounded per year is represented by the variable ____.While the annual interest rate is represented by___.
Answer:
1. (n) 2. (r)
Step-by-step explanation
interest compounded per year is (n),
annual interest rate is (r).
The number of times that interest is compounded per year is represented by the variable n. While the annual interest rate is represented by r.
What is the compound interest?Compound interest is the interest on savings calculated on both the initial principal and the accumulated interest from previous periods.
The formula used to find the compound interest = [tex]A=P(1+\frac{r}{100})^{nt}[/tex].
A = amount, P = principal, r = rate of interest, n = number of times interest is compounded per year and t = time (in years).
Therefore, the number of times that interest is compounded per year is represented by the variable n. While the annual interest rate is represented by r.

Which functions defines (f-g)(x)?
Answer: C I think
Step-by-step explanation:
The functions defines (f-g)(x) is √(x-8) - 2/x + 6.
Option D is correct.
What is Function?A mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable). In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.
We have,
f(x) = √(x /8) + 11
g(x) = 5 + 2/x
So, (f- g) (x)
= f(x)- g(x)
= √(x /8) + 11 - 5 - 2/x
= √(x-8) - 2/x + 6
Thus, the value of function √(x-8) - 2/x + 6.

Step-by-step explanation:
Aaron (A)=30 years old currently. (Aaron's son (S)=10 years old currently)
PREMISES
3S+10=2(S+10)
ASSUMPTIONS
Let A=Aaron's “current” age (3S in terms of his son's age)
Let S=Aaron's son's “current” age (S)
CALCULATIONS
3S+10=2(S+10)
3S+10=2S+20
(3S-2S)+10=(2S-2S)+20
S+10=0+20
S+(10–10)=20–10
S+0=10
S=
10 years old
and,
if S=10 years old, then
A=3S (Aaron's “current” age in terms of his son's age)
A=3(10)
A=
30 years old
PROOF
If A=30 years old, then the equations

What is centroid of a triangle and its coordinates?
The point of intersection of a triangle's medians is its centroid (the lines joining each vertex with the midpoint of the opposite side).
If the triangle has its vertices as [tex](x_1, y_1), (x_2, y_2) , \: (x_3, y_3)[/tex], then the coordinates of the centroid of that triangle is given by:
[tex](x,y) = \left( \dfrac{x_1 + x_2 + x_3}{3} + \dfrac{y_1 + y_2 + y_3}{3} \right)[/tex]
We are given that;
The figure
Now,
We know that in a triangle, whenever a line that passes through a vertex of the triangle such that is perpendicular to the opposite side is called an altitude of the triangle;
So, the point where all the three altitudes of the triangle meets is called its orthocenter .
From the given figure , we can conclude that the point V is the intersecting points of all the altitudes of the triangle STU.
Therefore, by centroid concept the answer will be Orthocenter.
