The vertex of a parabola is (-2, -20), and its y-intercept is (0, -12).
mart [117]
Vertex for is

y = a(x - h)^2 + k  where (h,k) is the vertex.

so we have

y = a(x - (-2)^2 - 20
y = a(x + 2)^2 - 20

y intercept is (0,-12) so:-

-12 =  a(2)^2 - 20
4a = 8
a = 2

y = 2(x + 2)^2 - 20    is the parabola in vertex form  Convert to standard form:-

y = 2(x^2 + 4x + 4) - 20
y = 2x^2 + 8x -12  is the answer

Can anyone please help me do 13 and 14 please
NeX [460]

Answer:

hey we can only see 13 and for 13 is<em><u> X = 57.36</u></em>

Step-by-step explanation:

since we have opposite and the hypotenuse we use sin...

sin(theta) = opp/hyp

sin(38) = 17/x

and we multiple x to both sides which leaves us with

x * sin(38) = 17

and then divide sin(38) so x can be by it- self which gives us

x = 17/sin(38

X = 57.36

Barney's Book Store currently has 2000 books in stock. There are 3 times as many non-fiction books as fiction books. Determine t
xxMikexx [17]

Answer:

There are 1500 non fiction books and 500 fiction books currently in the store.

Step-by-step explanation:

Given:

Total Number of books = 2000

Let the number of fiction books be 'x'.

Now given:

There are 3 times as many non-fiction books as fiction books.

Number of non fiction books = 3x

We need to find the number of non-fiction and fiction books.

Solution:

Now we know that;

Total Number of books is equal to sum of the number of non-fiction and fiction books.

framing in equation form we get;

x+3x=2000\\\\4x=2000

Dividing both side by 4 we get;

\frac{4x}{4}=\frac{2000}{4}\\\\x= 500\ books

Number of fiction books = 500

Number of non fiction books = 3x=3\times 500 =1500

Hence There are 1500 non fiction books and 500 fiction books currently in the store.

It takes a hose 2 minutes to fill a rectangular aquarium 8 inches long, 10 inches wide, and 14 inches tall. How long will it tak
kari74 [83]

Answer:

66 minutes, or 1 hour and 6 minutes.

Step-by-step explanation:

let us first do the rectangular aquarium:

8 x 10 = 80

80 x 14 = 1120

now the second box

23 x 25 = 575

575 x 33 = 18975

we can divide the boxes volume:

18975/575 = 33

so all we have to do is times 33 by 2 which equals:

66 minutes, or 1 hour and 6 minutes.
