Answer:

Yes the $20 bill will be enough to pay for all snacks.

Step-by-step explanation:

To slove this problem we have to find the cost of all snacks.

First lets find pretzels:

Each bag cost $3.49 and she bought 3 bags so

$3.49 * 3 = 10.47

Next find the hummus cost:

Each contaier is $4.19 and she bought 2 so

$4.19 * 2 = 8.38

Last add them together:

$10.47 + $8.38 = 18.85

That means we have more money left because $18.85 < $20.

What are the coordinates of the vertex of the parabola represent by the equation y=-5x^2+30x-25
Jobisdone [24]

Answer:

The coordinate of the  vertex of the parabola is (h,k) =  (3,20)

Step-by-step explanation:

The given equation of the parabola is y=-5x^2+30x-25

Now, the General Parabolic Equation is of the form:

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

Now, to covert the given equation in the standard form:

y=-5x^2+30x-25   = -5(x^2  -6x   + 5)

Using the COMPLETE THE SQUARE METHOD,

-5(x^2  -6x   + 5)  = -5(x^2  -6x  +  (3)^2 +  5  - (3)^2)\\\implies -5(((x^2  -6x +(3)^2)  + 5 - 9)\\= -5((x-3)^3 -4)\\= -5(x-3)^2 + 20

ory = -5(x-3)^2 + 20

⇒The general formed equation of the given parabola is

y  = -5(x-3)^2 + 20

Comparing this with general form, we get

h = 3, k = 20

Hence, the coordinate of the  vertex of the parabola is (h,k) =  (3,20)
