A parabola has a vertex of (5,4) and goes through the point (6,-10)

1 answer:

5 0

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

A dog breeder plans to mix two types of food to make a mix of low cost

lys-0071 [83]

Answer:

3.75 bags of ChowChow
0.75 bags of Kibble

Step-by-step explanation:

The constraints on protein, minerals, and vitamins give rise to the inequalities ...

40c +30k ≥ 150 . . . . . . required protein

20c +20k ≥ 90 . . . . . . required minerals

10c +30k ≥ 60 . . . . . . . required vitamins

And we want to minimize 10c +12k.

The graph shows the vertices of the feasible region in (c, k) coordinates. The one that minimizes cost is (c, k) = (3.75, 0.75).

To minimize cost, the daily feed should be ...

3.75 bags of ChowChow
0.75 bags of Kibble

Daily cost will be $46.50.

emmainna [20.7K]

Answer:

1 adult cat

Step-by-step explanation:

Thursday:

The ratio of adult cat to kitten at a pet care center on Thursday was 4:3.

Number of adult cats = 4x

Number of kitten cats = 3x

There were 12 kittens, then

$3x=12\\ \\x=\dfrac{12}{3}\\ \\x=4\\ \\4x=4\cdot 4=16$

There were 16 adult cats

Tuesday:

17 adult cats were at the pet care center.

Difference:

$17-16=1$ adult cat
