The Vertex form is y= 3(x+ 2)² -5 and a= 3, h= -2, k= -12.

What is Vertex Form?

The vertex form of a quadratic function is f(x) = a(x – h)² + k, where a, h, and k are constants.

Vertex form, one of the usual forms for quadratic functions, emphasises the coordinates of the vertex of the function's graph.

Given:

y = 3x² + 12x + 7

Now writing the equation in vertex form

y = 3x² + 12x + 7

y = 3x(x + 4) + 7

Adding and subtracting 12 on both side

y= 3(x²+ 4x) + 7 -12 + 12

y= 3(x² + 4x + 4) + 7- 12

y= 3(x+ 2)² -5

Now, Comparing it with y = a(x - h)² + k we get

a= 3

h= -2

and, k= -12

If the asymptotes of a hyperbola are the x- and y-axes, it is known as a rectangular hyperbola?

Answers

Yes, This is true. If the asymptotes of a hyperbola are the x- and y- axes, it IS known as a rectangular hyperbola.

Final answer:

A rectangular hyperbola is defined by the angle between its asymptotes being 90°, with its Equation represented as x'y' = a².

Explanation:

Rectangular Hyperbola: When the angle between the asymptotes of a hyperbola is 90°, it is called a rectangular hyperbola. In this case, b = a and the eccentricity is √2. The Equation to a rectangular hyperbola is x'y' = a².

Find a1 for the arithmetic series with s20 = 80 And d = 2

Answers

we know that
the formula of the arithmetic series is
Sn=n[2(a1) + (n - 1)d]/2
where
Sn=80
n=20
d=2
a1=?
then
80=20*[2*a1+19*2]/2----------------> 160=[40*a1+760]
160=[40*a1+760]----------> a1=(160-760)/40------------> a1=-15

the answer is
a1=-15

To solve this, we are going to use the standard formula for arithmetic series [tex]S _{n} = \frac{n}{2} [2a_{1} +(n-1)d][/tex]
where:
[tex]S_{n} [/tex] is the sum of the arithmetic sequence
[tex]n[/tex] is the number of terms
[tex]d[/tex] is the difference
[tex]a_{1} [/tex] is the first term
From our problem we know that [tex]S_{n} =80[/tex], [tex]n=20[/tex], and [tex]d=2[/tex]. Lets replace those values in our formula to find [tex]a_{1} [/tex]:
[tex]80= \frac{20}{2} [2a_{1} +(20-1)2][/tex]
[tex]80=10(2a_{1} +38)[/tex]
[tex]80=20a_{1} +380[/tex]
[tex]20a_{1} =-300[/tex]
[tex]a_{1} = \frac{-300}{20} [/tex]
[tex]a_{1} =-15[/tex]

We can conclude that the first term [tex]a_{1} [/tex] of the arithmetic series is [tex]-15[/tex]

During each minute of a comedy show, Carlin laughs 555 times. Carlin watches 333 comedy shows every day, and each show is 404040 minutes long. How many times does Carlin laugh every day due to the comedy shows?

Answers

74,672,652,600. Take the time of the show and multiply it by the number of times she laughs in a minute. Then multiply that by the number of shows she watches in a day. That number seems pretty large though so you may want to make sure you have the right numbers and that it's not just 5 times, 3 shows, and 40 minutes.

Answer: 600

Step-by-step explanation:

Given : The number of times Carlin laughs in each minute = 5

The number of comedy show Carlin watched = 3

The length of each comedy show = 40 minutes

Total minute she watched Comedy show will be :-

[tex]40\times3=120\text{ minutes}[/tex]

Then , the total number of times Carlin will be :-

[tex]120\times5=600[/tex]

Hence,Carlin laughs 600 times every day due to the comedy shows.

In the standard (x,y) coordinate plane below, the points ( 0,2), (8,2), (3,6), and (11,6) are the vertices of a parallelogram. What is the area, in square units, of the parallelogram

Answers

Your area would be 32, 8 by 4 is what the formula is

The area of the parallelogram is 32 square units.

What is a parallelogram?

Parallelogram is a quadrilateral that has two pairs of parallel sides.

In a parallelogram, opposite sides and angles are equal.

The adjacent angles add up to 180 degrees.

We have,

First, we can plot the points on the coordinate plane to get a better visual understanding of the parallelogram:

| (3,6) (11,6)

| *-----------*

| / /

| *-----------*

| (0,2) (8,2)

Now,

We can see that the base of the parallelogram is the line segment connecting (0,2) and (8,2), which has a length of 8 units.

To find the height of the parallelogram, we can observe that the line segment connecting (0,2) and (3,6) is perpendicular to the base, and has a length of 4 units.

Therefore,

The height of the parallelogram is 4 units.

Now,

The area of a parallelogram is given by the formula:

Area = base x height

Plugging in the values we found, we get:

Area = 8 x 4

Area = 32

Therefore,

The area of the parallelogram is 32 square units.

as far as its graph, is more or less like the picture below, now, notice that if we put the quadratic in "vertex form", it'd look like

GIVEN circle P with arc AE = 53 , arc BA =68 and arc CB =72

match the following angles with their corresponding measurements

Answers

the theory that is mainly used to find out the angles of the above diagram is that;
the sum of the internal angles of a triangle is 180°.
when the angles of arcs have been given(e.g: BA) that means from the centre of the circle to point B has been rotated by 53° to point A.
Next from point A to point E, the angle rotated is 68°

the addition of these 2 angles give the angle rotated from point B to point E,
that is angle no.7

m∠7 = 53° + 68° = 121°
consider ΔPBE,
PB and PE are radii therefore isosceles triangles
In isosceles triangles the angles opposite equal sides are equal
if the angle is x°, then there are 2 angles with values x each
x° +x° + 121° = 180°
2x° = 59°
x = 29.5°
therefore m∠3 = 29.5°

next connect PC and consider ΔPCB,
according to given information, C∠PB = 72°
as PC and PB are radii ΔPCB is an isosceles triangle, then the angles (y°) opposite radii are equal
2y° + 72° = 180°
y° = 54°
then consider ΔPCD, again an isosceles triangle
as a straight line has an angle of 180°
B∠PC + C∠PD = 180°
72° + C∠PD = 180°
C∠PD = 108°
as ΔPCD is an isosceles triangle, P∠CD and P∠DC are equal (take this angle as z°)
2z° + 108° = 180°
z° = 36°
B∠CD is a sum of y and z angles
therefore m∠8 = y + z
m∠8 = 54° + 36° = 90°
there is also a tangent line that cuts point D of the circle. this tangent cuts D and is perpendicular to the PD radius
this indicates that lines PD and HD are perpendicular to each other
hence, forms a right angle where it cuts each other.
therefore H∠DP / m∠4 = 90°
C∠DH /m∠5 is the difference between P∠DH and P∠DC
m∠5 = 90° - 36° = 54°

m∠1 and m∠6 together make a straight line therefore the sum of these 2 angles is 180°
by looking at the options of answers given the 2 angle values given that add up to 180° are 116.5° and 63.5°.
m∠1 is the acute angle therefore m∠1 = 63.5°
m∠6 is the obtuse angle therefore m∠6 = 116.5°

consider ΔDFB
D∠FB is 180° - m∠1 = 180° - °63.5 = 116.5°
D∠FB + F∠DB(w°) + D∠BF (m∠3)= 180°
116.5 + w° + 29.5° = 180°
w° = 34°
m∠2 = m∠4 + w°
= 90° + 34°
= 124°

m∠1= 63.5°
m∠2 = 124°
m∠3 = 29.5°
m∠4 = 90°
m∠5 = 54°

We apply this property to get:

Sean divides 8 cups of granola into 1/4-cup servings. How many servings of granola does he have?

Answers

Think of this, 8 is a whole number right? You can put a 1 under that 8 and it will still be a whole number, You basically flip 1/4 as a fraction, Which will make it 4/1. You can multiply the 8 and 4 which will equal 32, You can add that 1 under the 32 if that helps you but the answer, in general, is 32

1 cup makes 4 servings
8 cups make x

x = 8*4
x = 32 servings
