The equivalent value of the sum for any value of "x" is 12x - 6
How to find the sum of functions?Given the sum of the expression as:
3
∑ k(2x-1)
k=0
We need to take the sum of the function at the point where k = 0 to 3
3
∑ k(2x-1) = 0(2x-1) + 1(2x - 1) + 2(2x-1) + 3(2x - 1)
k=0
3
∑ k(2x-1) = 2x-1+4x-2+6x-3
k=0
3
∑ k(2x-1) = 12x - 6
k=0
Hence the equivalent value of the sum for any value of "x" is 12x - 6

The table is shaped like a trapezoid. The sum of the lengths of both bases is 90 inches. The area is
1,170 square inches. Write an equation to find the height of the table.
HELPP
Answer:
Step-by-step explanation:
Formula (Normal Area Trapezoid)
A = (b1 + b2 ) * h / 2
Formula (Trapezoid Modified for the question)
b1 + b2 is given as 90
Area = 90*h / 2
Givens
b1 + b2 = 90
Area = 1170
h = ?
Solution
Area = 90 * h / 2 Substitute the givens into the formula
1170 = 90 * h/ 2 Divide by 2 on the right.
1170 = 45 * h Divide both sides by 45
1170 / 45 = 45 * h/45
Answer: h = 45 inches.

Answer:
third side = 6
using pythagoras theorem:
a² + b² = c²
5² + (√11)² = c²25 + 11 = c²36 = c²c = √36c = 6Answer:
The length of the third side is 6 units
Step-by-step explanation:
We know that this is an right angled triangle , so
by using Pythagoras theorem we can find out the third side of the triangle ..
=> P² + B² = H²
=> 5² + (√11)² = H²
=> 25 + 11 = H²
=> 36 = H²
=> √36 = H
=> 6 = H
For circle h, jn = 3, nk = x, ln = 2, and nm = 6. solve for x. circle h with chords jk and lm intersecting at n inside the circle 9 1 5 4
The circle is an illustration of intersecting chords.
The value of x is 4
How to determine the value of x?The given parameters are:
Chords: jk and lmPoint of intersection = njn = 3, nk = x, ln = 2, and nm = 6This means that:
jn * nk = ln * nm
So, we have:
3 * x = 2 * 6
Divide both sides by 3
x = 2 * 2
Evaluate the product
x = 4
Hence, the value of x is 4

Write an equation for a quadratic function in vertex form with a vertex of (3,1) that has the point
(1,5).
Answer:
y = (x - 3)² + 1
Step-by-step explanation:
the equation of a quadratic function in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
here (h, k ) = (3, 1 ) , then
y = a(x - 3)² + 1
to find a substitute (1, 5 ) into the equatiuon
5 = a(1 - 3)² + 1 ( subtract 1 from both sides )
4 = a(- 2)² = 4a ( divide both sides by 4 )
1 = a
then equation of quadratic function is
y = (x - 3)² + 1

Step-by-step explanation:
move the parent function to the right 2 times.
Answer:
see image
Step-by-step explanation:
An absolute value graph is a V-shaped graph(in yellow, see image) You can use "transformations of parent functions" to graph it (high school/college) OR use a table of values (middleschool/hs). The - 2 that's in the parenthesis with the x causes the graph to slide to the RIGHT 2 units. (shown in green) The green graph is what you are asking for.
If you aren't learning about translations (which means shift or slide and is a type of transformation) then you can just make a table of values. Pick several x's and put them in the equation and find out what y's go with them. Plot the points on the graph and connect. See image.

What we know:
Bird feeder capacity: --> 2 4/5 cupsSamantha's scoop capacity: --> 7/10 cupsLets first convert the mixed partial fraction --> improper fraction
--> for easier calculation
After Conversion:
Bird feeder capacity: --> 14/5 cupsSamantha's scoop capacity: --> 7/10 cupsTo find how many scoops of birdseed will Samantha put into the feeder we must:
--> divide the total capacity by the scoop's capacity
--> find the number of scoops:
Solve:
[tex]Total-number- of -scoops = \frac{\frac{14}{5} }{\frac{7}{10} } =\frac{14}{5} *\frac{10}{7} =\frac{14*10}{5*7} =\frac{14}{7} *\frac{10}{5} =2*2=4[/tex]
Thus the total number of scoops that Samantha will put into the bird feeder is 4

A line parallel to the graph of (y − 4) = m(x − 7) passes through (−1,−2) and (m, 10). If
m > 0, what is the value of m?
Answer:
Step-by-step explanation:
Givens
These are the givens for the second line. The second line also has m (same value) as the x coordinate of one of the points. I'm not sure why you are given the first line.
x1 = - 1
x2 = m
y1 = - 2
y2 = 10
Second line formula for m
m = (y2 - y1) / (x2 - x1) Substitute values for this equation
Solution
Note that the m you seek is both the slope of the second line, and the x coordinate of one of the points.
m = (10 - - 2) / (m - - 1) Change the double minus, and combine
m = 12 / (m + 1) Multiply both sides by (m + 1)
m(m+1) = 12 Remove the brackets
m^2 + m = 12 Subtract 12 from both sides.
m^2 + m - 12 = 0 Factor
(m + 4)(m - 3) = 0
We are told that m >0
So m- 3 = 0
m = 3
Answer
The value for m = 3. The first line also has a slope of 3

What is preference ballot?A preference ballot is a type of ballot used in elections where voters indicate their order of preference for the candidates or options listed on the ballot.
Instead of simply selecting one option, voters rank the options in order of their preference, usually by indicating a first-choice, second-choice, and so on.
Preference ballots require more complex calculations to determine the winner, especially when there are more than two candidates. This can result in delays in announcing the results and can be time-consuming to compile.
Thus, this can result in delays in announcing the results and can be time-consuming to compile.
