The math club needs to raise more than $552. $.50 for a trip to state competition. The club has raise 12% of the funds which is

ratelena [41]

Each of the members must raise at least $69.46.

To start they need to raise $552.50. However, they have already raised 12% of it. They only need to raise 88% of it.

552.50 x 0.88 = 486.2

Divide the remaining amount by 7 to determine how much each individual must raise.

486.2 / 7 = 69.46

The graph of a quadratic function has a vertex at (5,3) and goes through the point (-1,-9). What is the equation of the function

kotegsom [21]

Answer:

$y=-\frac{1}{3} (x-5)^2+3$

Step-by-step explanation:

We are given the following;

Vertex of a quadratic function = (5,3)
A point where the function passes through (-1, -9)

Required to determine the equation of the function;

We need to know the vertex form of a quadratic function is;

$y=a(x-h)^2+k$ , where h and k correspond to the vertex (h,k)

Therefore, we can replace the variables h and k of the vertex in the equation;

That is;

$y=a(x-5)^2+3$

Then we use the equation and the point given to solve for a

x = -1 and y = -9

We get;

$-9=a(-1-5)^2+3\\-9 = a(36) + 3\\-9 - 3 = 36a\\-12 =36a \\a=-\frac{1}{3}$

Substituting the values of a, h and k in the equation, we get;

$y=-\frac{1}{3} (x-5)^2+3$

Thus, the equation of the function in the vertex form is $y=-\frac{1}{3} (x-5)^2+3$

madreJ [45]

Answer:

A

Step-by-step explanation:

To find the distance between V1 and AQ use the distance formula

$d = \sqrt{(x2-x1)^2+(y2-y1)^2}$

First find the coordinates of both V1: (-6, 5) AQ: (5, 5)

Now plug it in and solve for d (11)

What is the measure of MN

Paul [167]

Answer:

C

Because of the markings showing equal length lines 7x + 4 is double 4x or 48 is three times the length of 4x

Either solve 7x + 4 = 8x

4 = x

Or solve 48 = 12x

4 = x

Substitute back in to 7x + 4 ......MN = 7 x 4 + 4 = 32
