Why is the vertex of vertex form y=a(x-h)^2+k (h,k) rather than (-h,k)? If that was y=2(x-5)^2+6, the vertex would be at (5,6) which is (-h,k).
9514 1404 393
Answer:
(5, 6) is (h, k)
Step-by-step explanation:
Vertex form is an instance of the transformation of parent function f(x) = x². It is vertically scaled by a factor of 'a', and translated so the vertex is point (h, k). That is, the transformed vertex is h units right and k units up from that of the parent function (0, 0).
Parent:
f(x) = x^2
Transformed:
f(x) = a(x -h)^2 +k
__
When you compare the form to your specific instance, you need to pay attention to what it is that you're comparing. As the attachment shows, ...
a = 2-h = -5 ⇒ h = 5k = 6Hence the vertex is (h, k) = (5, 6). The second attachment shows this on a graph.
Trapezoid LMNO with bases LM and ON , and Median PQ
If PQ = t +6, LM = t +3 and ON = 3t – 7, find ON
The length of base ON of trapezoid LMNO is 17 units
We know that the median theorem of trapezoid, which states that the median of a trapezoid is parallel to each base. Also, the length of the median equals one-half the sum of the lengths of the two bases.
Consider the following diagram of trapezoid LMNO with bases LM and ON , and Median PQ.
Given that the equations for the bases and median of trapezoid LMNO .
PQ = t +6, LM = t +3 and ON = 3t – 7
From above theorem,
PQ = 1/2 (LM + ON)
t + 6 = 1/2 ( t + 3 + 3t - 7)
2(t + 6) = 4t + 3 - 7
2t + 12 = 4t - 4
4t - 2t = 12 + 4
2t = 16
t = 8 units
So, ON = 3t - 7
ON = 3(8) - 7
ON = 24 - 7
ON = 17 units

What is quadratic equation?The equation of two-degree polynomial having one variable is called quadratic equation.
The solution of a quadratic equation is either real or complex. We use quadratic equation formula for solution whenever we cannot expand, and factoring a given two-degree polynomial equation.
How to solve the given equation?given equation, x² = 6x -10
x²-6x +10 =0
This equation cannot be expanded so we need to write the formula for quadratic equation to solve it.
we know that standard form of a quadratic equation is given by
ax² + bx +c = 0
where a is the coefficient of x², b is the coefficient of x and c is the constant.
the solution of the equation is given by x = -b ± √ (b² - 4ac) / 2a
Now, the solution for the above equation is x = 6 ± √ (6² - 4×1×10) / 2×1
x = 6 ± √ (36 -40) / 2
x = 6 ± √-4 / 2
as √-4 = √-1 ×2
x = 6 ± 2 √-1 /2
divide both numerator and denominator by 2
x = 3± i as √-1 = i
this is the solution in (a + bi) form a = 3 and b = 1

the function f(x)=80(0.5)^ represents the distance after a pendulum begins swinging,where x is the number of swings
It looks like there may be a typo in the function you provided. It appears that you meant to write "f(x) = 80(0.5)^x", which would represent the distance after a pendulum begins swinging, where x is the number of swings.
This function indicates that the distance traveled by the pendulum decreases by half with each swing. For example, after the first swing, the distance traveled would be 80(0.5)^1 = 40 units. After the second swing, the distance traveled would be 80(0.5)^2 = 20 units. And so on.
The exponent x in the function represents the number of swings, so the distance traveled by the pendulum can be calculated by plugging in the desired value of x into the function. For example, to calculate the distance traveled after 10 swings, we can plug in x = 10:
f(10) = 80(0.5)^10 = 0.390625 units
This indicates that the pendulum has traveled a distance of approximately 0.39 units after 10 swings.

The plot for histogram is given below. Through digits distribution it can be seen that last digit of height of many students are same and the heights appear to be reported.
What is frequency distribution?
To make the information easier to understand, frequency distributions are visual displays that organise and present frequency counts. Absolute frequencies as well as relative frequencies, such as percentages or ratios, can be displayed in frequency distributions.
The table of data is given below.
According to the table the histogram is plotted.
The graphic representation of data points arranged into user-specified ranges is called a histogram. The histogram, which resembles a bar graph in appearance, condenses a data series into an intuitive visual by collecting numerous data points and organising them into logical ranges or bins.
The digits distribution show that the maximum number of students have a height whose last digit is 3.
The heights appears to be reported by the students and not actually measured as maximum of them are having same last digit which corresponds to the possibility that the first digit might be different. This is a possible example of a survey.

What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
The line passes through points (-4, -6) and (9, 2).
Let the equation of the line y = mx + c.
Now,
m = (2 + 6) / (9 + 4) = 8/13
(-4, -6) = (x, y)
-6 = (8/13) x -4 + c
-6 = -32/13 + c
c = -6 + 32/13
c = (-78 + 32)/13
c = -46/13

Step-by-step explanation:
find the length of side xx in simplest radical form with a rational denominator.
For given right triangle, the length of hypotenuse x = 4/√3
Here we have been given a 30° - 60°- 90° right triangle.
A side opposie to angle 60 degrees measures 2 units.
And x is the hypotenuse of right tirnagle.
To find the value of x, consider sine of angle 60 degrees.
sin(60°) = (opposite side of angle 60°) / hypotenuse
From tirgonometric table, sin(60°) = √3 / 2
So, above equation becomes,
√3/ 2 = 2/x
x = 2 × (2/√3)
x = 4/√3
We can see that the value of x is in in simplest radical form with a rational denominator.

The dimensions length is 10 feet, width is 10 feet and height is 5 feet and the smallest possible surface area is 300 square feet.
Volume=lbh
lbh=500 cubic feet
h=500/lb
Surface area S=lb+2bh+2lh...(1) {rectangular tank has no top}
S=lb+2b(500/lb)+2l(500/lb) {substituting the value of h in 1}
S=lb+1000/l+1000/b { partially differentiating S with respect to l and b}

dS/dl= b-1000/l^2
dS/dl=0
b=1000/l^2...(2)
dS/db= l-1000/b^2
dS/db=0
l=1000/b^2
l=1000/(1000/l^2)^2 {substituting the value of b from 2}
l=(1000 x l^4)/(1000000)
1000000/1000=l^4/l
1000=l^3
