Answer:

Step-by-step explanation:

1)

y=-x^2-4x-1\\=-(x^2+4x+4)+4-1\\=-(x+2)^2+3\\\\Vertex=(-2;3)\\\\

2)

y+x^2+2=0\\y=-x^2-2\\\\y=-(x-0)^2-2\\Vertex=(0;-2)\\

A parabola has a vertex of (5,4) and goes through the point (6,-10)
natali 33 [55]
Y = -2(x-5)^2 + 4

Note: vertex form is 0, f(x), y, or nothing= a(x-h)^2 + k
The opposite of the x value of the vertex is h
The y value value of the vertex is k.


Find a. Plug in (6,-10)

-10 = a(6-5)^2 + 4
-10 = 1a + 4
-10 = 5a
a = -2

Explain how you can use doubles when multiplying with 4 to find 4x8
hoa [83]
When multiplying by 4, you can simply multiply it by 2 twice (prime factorization).
In this example-
4 times 8 = 32
2 times 2 times 8 = 32

Hope this helped!
By the way, I'm getting closer to leveling up, so if you liked my answer, you could reward me with brainliest answer. That'd be great!

I need help with #7 c and d
Misha Larkins [42]

Answer:

  c. 33.0%

  d. 14.5%

Step-by-step explanation:

For answering questions about percentages in different categories or combinations of categories, it is convenient to find the totals of rows and columns in the table. These totals are shown in the attached.

__

<h3>c.</h3>

Students who surf total 32+65 = 97. Of those, 32 also skateboard. The requested percentage is ...

  32/97 × 100% ≈ 33.0% . . . . surfers who also skateboard

__

<h3>d.</h3>

The total number of students is 166. Of those, the number who neither surf nor skateboard is 24. That percentage is ...

  24/166 × 100% ≈ 14.5% . . . . students who don't surf or skateboard

_____

<em>Additional comment</em>

a. 97/166 ≈ 58.4% surf

b. 89/166 ≈ 53.6% do not skateboard

__

This sort of table is called a "two-way table." One set of categories is represented in rows, another set is represented in columns. This table is filled with <em>frequencies</em>. Such tables can also display <em>relative frequencies</em> by dividing the entire table by the total of totals in the lower right corner.
