Write an equation of the parabola in vertex form that passes through (0, −24) and has vertex (−6, −12)
Elenna [48]
The general equation is y-k=a(x-h)² where (h,k) is the vertex.

So in this case we have y+12=a(x+6)².

Plug in x=0, y=-24: -12=36a, and a=-⅓. Therefore y+12=-⅓(x+6)².

2. Write a quadratic function that has -intercepts (- 3, 0) and (4, 0) and passes through the point (5, 8)
Reptile [31]

Answer:

f(x)=x^2-x-12

Step-by-step explanation:

<u>Quadratic Function</u>

Standard Form of Quadratic Function

The standard representation of a quadratic function is:

f(x)=ax^2+bx+c

where a,b, and c are constants.

When the zeros of f (x1 and x2) are given, it can be written as:

f(x)=a(x-x1)(x-x2)

Where a is a constant called the leading coefficient.

We are given the two roots of f: x1=-3 and x2=4, thus:

f(x)=a(x+3)(x-4)

We also know that f(5)=8, thus:

f(5)=a(5+3)(5-4)=8

Operating:

a(8)(1)=8

Solving:

a=1

The function is:

f(x)=1(x+3)(x-4)

Operating:

\boxed{f(x)=x^2-x-12}

Help pleaseeeeee sissiisisjsiss
Bumek [7]

9514 1404 393

Answer:

  i) ∠AOB = 87°

  ii) ∠BOC = 72°

  iii) ∠COD = 123°

  iv) ∠AOD = 78°

Step-by-step explanation:

The first three angle measures can be read from the diagram. Find the rays that define the angle, and read the measure of the arc between them.

The last angle, AOD, is found using the fact that the sum of all of the angles around a point is 360°.

  87° +72° +123° +∠AOD = 360°

  ∠AOD = 360° -282° . . . . . . . . . . subtract 282° from both sides

  ∠AOD = 78°

Any help? Explanation would help massively too! Work out the length of AB
____ [38]

Answer:

Exact length = 2*sqrt(137)   cm

Approximate length = 23.409  cm

====================================================

Work Shown:

Use the Pythagorean theorem

a^2 + b^2 = c^2

8^2 + 22^2 = c^2

64 + 484 = c^2

548 = c^2

c^2 = 548

c = sqrt(548)

c = sqrt(4*137)

c = sqrt(4)*sqrt(137) ..... use the rule sqrt(x*y) = sqrt(x)*sqrt(y)

c = 2*sqrt(137)  .... this is the exact length

c = 23.4093998214392 ... use your calculator to find the approximate length

c = 23.409

I rounded to three decimal places, but feel free to round however you want. Or be sure to follow any rounding instructions your teacher provides.

Please, let this be a normal field trip [Wanda:] With the Friz? [Kids:] No way! [Arnold:] Oh!
vova2212 [387]

Answer:

1. x= 5, x=1

2. x= -4, x=2

3. x= -6, x=7

4. x= -7, x=5

5. x= -9, x=0

Step-by-step explanation:

<em>You do the X factoring-</em>

1.

A   B   C

x²+6x+5

(A)(C) and B

(1)(5)=5      6

Then figure out what two numbers multiply to get 5

but also add to 6. In this case, it would be 5 and 1

5x1= 5 and 5+1= 6

so it is:

x= 5, x= 1

Hope this helps!
