Answer:

There are 6 green beads there.

Step-by-step explanation:

This question can be solved by a system of equations.

I am going to say that:

x is the number of green beads

y is the number of yellow beads

The ratio of green beads to yellow beads in a bracelet is three to four.

This means that

\frac{x}{y} = \frac{3}{4}

So

3y = 4x

y = \frac{4x}{3}

The total number of beads is 14.

This means that x + y = 14

How many green beads are there ?

This is x.

x + y = 14

However

y = \frac{4x}{3}

So

x + \frac{4x}{3} = 14

Using multiplying by the gcm(3)

3x + 4x = 42

7x = 42

x = 6

There are 6 green beads there.

Question 11

The directrix is a horizontal line, which means the parabola opens either upward or downward. In this case, it opens downward. This is because all answer choices have a negative leading coefficient. Also, it's because the focus is below the directrix.

For vertically opening parabolas, we use this form

4p(y-k) = (x-h)^2

where (h,k) is the vertex and p is the focal distance, aka the distance from the vertex the focus. To find (h,k), we start at the focus (0,-4) and move directly up until we reach the directrix y = 4. We'll arrive at (0,4). The midpoint of (0,-4) and (0,4) is (0,0) which is the vertex's location. So (h,k) = (0,0).

Note that in moving from (0,-4) to (0,4) is a span of 4 units. So this is the value of p.

Plug h = 0, k = 0, p = 4 into the equation mentioned and solve for y

4p(y-k) = (x-h)^2

4*4(y-0) = (x-0)^2

16y = x^2

y = (1/16)x^2

The only adjustment we need to make is to change the 1/16 to -1/16 so that the parabola opens downward.

<h3>Answer:  Choice D.  y = -(1/16)x^2</h3>

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

Question 3

The given equation is in the form y = ax^2+bx+c

In this case,

  • a = 2
  • b = 4
  • c = 3

Let's compute the x coordinate of the vertex h

h = -b/(2a)

h = -4/(2*2)

h = -1

This h value is plugged into the original function to find k

f(x) = 2x^2+4x+3

f(-1) = 2(-1)^2+4(-1)+3

f(-1) = 1

We find that h = -1 and k = 1 pair up together. In short, (h,k) = (-1,1) is the vertex.

<h3>Answer: Choice B.  (-1,1)</h3>

Determine whether this system of equations has one solution, no solution, or infinitely many solutions.
prohojiy [21]

Answer:

The only solution I see is for x=0

Step-by-step explanation:

y=8x+2

y=-8x+2

y=y so substitute:

8X+2=-8X+2

Subtract 2 from each side

8X=-8X

divide each side by 8

x=-x

The only solution I see is for x=0
