When the function is given in vertex form y = a (x minus h) squared + k, how is the vertex found? a. (k, h) c. (h, k) b. (x, y) d. (y, x)
For the form [tex]y = a(x-h)^2 + k[/tex], the vertex has coordinates (h, k). The vertex is found by (x, y).
What is the vertex form of a quadratic equation?If a quadratic equation is written in the form
[tex]y=a(x-h)^2 + k[/tex]
then it is called to be in vertex form.
It is called so because when you plot this equation's graph, you will see vertex point(peak point) is on (h,k)
First of all, we used this vertex formula thing since it is visible that there are quadratic functions.
Otherwise, you had to use calculus to get critical points, then a second derivative of functions to find the character of critical points as minima or maxima or saddle, etc to get the location of vertex point.
This point (h,k) is called the vertex of the parabola that the quadratic equation represents.
For the form
[tex]y = a(x-h)^2 + k[/tex], the vertex has coordinates (h, k)
Thus, for the obtained form, we get the coordinates of the vertex as:
[tex]h = -b/2a,, \\ k = c - a\times(b/2a)^2[/tex]
Thus, the coordinates of vertex of [tex]y = ax^2 + bx + c[/tex]is:
[tex](h,k) = (-b/2a, c - a \times (b/2a)^2 )[/tex]

The equation of the parabola will be y = 1/8(x- 3)² - 4. Then the correct option is B.
What is the parabola?It's the locus of a moving point that keeps the same distance between a stationary point and a specified line. The focus is a non-movable point, while the directrix is a non-movable line.
Identify the vertex, focus, and directrix of the graph.
Then the equations representing the parabola in the graph will be
y = a(x - h)² + k
Then the vertex is at (3, -4). Then we have
y = a(x - 3)² - 4
For x = 0, the value of y will be -2.875.
-2.875 = a(0 - 3)² - 4
a = 1/8
Then the equation of the parabola will be
y = 1/8(x- 3)² - 4
Thus, the correct option is B.

Goblin Gryh can count the coins in a bag in 10 minutes. If goblin Girt counts with him, they can count all the coins in 6 minutes. How long would it take Goblin Girt to count the coins in the bag alone.
The Goblin Girt take 15 minutes to count the coins in the bag alone if Goblin Gryh can count the coins in a bag in 10 minutes. If goblin Girt counts with him, they can count all the coins in 6 minutes.
What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
Let's suppose the Goblin Girt take x minutes to count the coins in the bag alone.
Then we can frame an equation to find the value of x:
[tex]\rm \dfrac{1}{x}+\dfrac{1}{10}=\dfrac{1}{6}[/tex]
[tex]\rm \dfrac{1}{x}=- \dfrac{1}{10}+\dfrac{1}{6}[/tex]
[tex]\rm \dfrac{1}{x}=\dfrac{1}{15}[/tex]
x = 15 minutes (reciprocal on both sides)
Thus, the Goblin Girt take 15 minutes to count the coins in the bag alone if Goblin Gryh can count the coins in a bag in 10 minutes. If goblin Girt counts with him, they can count all the coins in 6 minutes.

Donna travels 70 miles at an average speed of 40 mph. she then travels a further 30 miles. the average speed for the entire journey is 44 mph. assuming donna didn't stop, what was her average speed for the final 30 miles to 2 dp?
If donna didn't stop, her average speed for the final 30 miles to 2 dp is; 57.39 mph
How to Calculate Average Speed?We are given;
Distance travelled by Donna = 70 miles
Average Speed of Donna = 40 mph
Additional Distance travelled = 30 miles
Average speed for entire journey = 44 mph
We know that;
time = distance/speed
Thus
Total time = (70 + 30)/44
Total time = 100/44 h
Time 1 = 70/40 = 7/4 hr
Time 2 = 30/v
Thus;
30/v + 7/4 = 100/44
Multiply through by 44 to get;
1320/v = 100 - 77
v = 1320/23
v = 57.39 mph

D(-9,7)
Answer:
y = -x/2 + 2
what are those mutli choice answers?
if that point is (6,1)
y = -x/2 + 4
Step-by-step explanation:
the perpendicular line has a gradient which is the negative inverse, that is -1/m
so the equation will be of the form y = -x/2 + c
substituting in the point (6, -1)
-1 = -6/2 + c
c = 2
so y = -x/2 + 2

With smell of steaks in passageways.

And at the corner of the street
A lonely cab-horse steams and stamps.
And then the lighting of the lamps.
Alfred Tennyson - Summer Night
Alfred Tennyson was another poet who made great use of visual imagery. See if you can get a clear picture of the summer night he describes in this poem "Summer Night:"
Now sleeps the crimson petal, now the white;
Nor waves the cypress in the palace walk;
Nor winks the gold fin in the porphyry font:
The firefly wakens: waken thou with me.
Now droops the milk-white peacock like a ghost,
And like a ghost she glimmers on to me.
Now lies the Earth all Danaë to the stars,
And all thy heart lies open unto me.
Now slides the silent meteor on, and leaves
A shining furrow, as thy thoughts in me.
Now folds the lily all her sweetness up,
And slips into the bosom of the lake.
So fold thyself, my dearest, thou, and slip
Into my bosom and be lost in me.
William Wordsworth - I Wandered Lonely as a Cloud
Next is an excerpt from "I Wandered Lonely as a Cloud" by William Wordsworth. The first and last stanzas show a progression of the poet's emotions using visual imagery.
I wandered lonely as a cloud
That floats on high o'er vales and hills,
When all at once I saw a crowd,
A host, of golden daffodils;
Beside the lake, beneath the trees,
Fluttering and dancing in the breeze.
For oft, when on my couch I lie
In vacant or in pensive mood,
They flash upon that inward eye
Which is the bliss of solitude;
And then my heart with pleasure fills,
And dances with the daffodils.

The whiskey on your breath
Could make a small boy dizzy;
But I hung on like death:
Such waltzing was not easy.
We romped until the pans
Slid from the kitchen shelf;
My mother’s countenance
Could not unfrown itself.
The hand that held my wrist
Was battered on one knuckle;
At every step you missed
My right ear scraped a buckle.
You beat time on my head
With a palm caked hard by dirt,
Then waltzed me off to bed
Still clinging to your shirt.

A function is shown: f(x) = 16x2 − 1.
Choose the equivalent function that best shows the x-intercepts on the graph.
f(x) = (4x + 1)(4x − 1)
f(x) = (8x + 1)(8x − 1)
f(x) = 4(x2 + 1)
f(x) = 8(x2 − 1)
The equivalent function of f(x) = 16x^2 - 1 is f(x) = (4x + 1)(4x -1)
How to determine the equivalent function?The function is given as:
f(x) = 16x^2 - 1
Express 16 as 4^2 and 1 as 1^2
f(x) = (4x)^2 - 1^2
Apply the difference of two squares
f(x) = (4x + 1)(4x -1)
Hence, the equivalent function of f(x) = 16x^2 - 1 is f(x) = (4x + 1)(4x -1)

You cut the 2 inch by 4 inch piece of wood along the indicated diagonal. Find the perimeter and area of the cross section formed by the cut
The perimeter of the cross section formed is 44.22 in.
The area of the cross section formed is 72.44 in.²
Calculating the area and perimeter of a rectangle
From the question, we are to determine the perimeter and area of the cross section formed by the cut
As indicated in the diagram,
If the wood is cut along the indicated diagonal, the cross section formed is a rectangle whose length will be the length of the diagonal and its width will be 4 in.
Now, we will calculate the length of the diagonal,
Let the diagonal be d
Then, we can write that
d² = 2² + 18²
d² = 4 + 324
d² = 328
d = 18.11 in.
Thus,
The length of the rectangular cross-section is 18.11 in.
Now, using the formula for calculating the perimeter of a rectangle
P = 2(l +w)
Where P is the perimeter
l is the length
and w is the width
For the rectangular cross-section
l = 18.11 in.
w = 4 in.
Putting the parameters into the formula,
P = 2(18.11 + 4)
P = 2(22.11)
P = 44.22 in.
∴ The perimeter of the cross section formed is 44.22 in.
For the area of the cross section
Using the formula for calculating the area of a rectangle,
A = l × w
∴ Area of the cross section formed = 18.11 × 4
Area of the cross section formed = 72.44 in.²
Hence, the area of the cross section formed is 72.44 in.²

What is the value of x? (3 ponts)
_/3
Step-by-step explanation:
I assume the 2 vertical lines are parallel.
then the 2 angles 5x and 4x are around the intersection point of both lines (since parallel lines simply mimic the behavior of each other, the angles must be the same).
that means 4x is also the angle under the indicated 5x angle, and 5x is also the angle under the indicated 4x angle.
and that simply means that 5x and 4x supplement each other to 180° (as all angles around a single point on one side of a line represent a half-circle and therefore 180°).
so,
5x + 4x = 180
9x = 180
x = 20
Rectangle ABCD is going to be reflected over the x-axis. Which of the following will not be one of the new coordinates? Group of answer choices (6, -6) (-6, 2) (-3, 2) (-3, 6)
Using translation concepts, it is found that the following rule is applied to each point:
(x,y) -> (x,-y).
The point that is does not result from this transformation will not be one of the new coordinates.
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
When a function is reflected over the x-axis, it's output is multiplied by -1, hence the rule is given by:
(x,y) -> (x,-y).
Thus, this rule is applied to all points, which are A, B, C and D, and the point that is does not result from this transformation will not be one of the new coordinates.
