Answer:

The answer to your question is y = 2(x + 8)²

Step-by-step explanation:

This is a vertical parabola that opens upwards

The distance from the vertex to the directrix is 1/8 so p = 1/8.

Equation

(x - h)² = 4p(y - k)

h = -7

k = 0

p = 1/8

Substitution

(x + 8)² = 4(1/8)(y - 0)

Vertex form equation

(x + 8)² = 1/2(y)

y = 2(x + 8)²

x² + 16x + 64 = 1/2y

2x² + 32x + 128 = y

General equation

2x² + 32x - y + 128 = 0

E/4 + 2d - 3 when e = 12 and f = 1/2.

Oxana [17]

Given that,

An expression : $\dfrac{e}{4}+2f-3$

To find,

The value of the above expression when e = 12 and f = 1/2

Solution,

We have,

$\dfrac{e}{4}+2f-3$

Put e = 12 and f = 1/2

So,

$=\dfrac{12}{4}+2\times \dfrac{1}{2}-3\\\\=3+1-3\\\\=1$

So, the value of the above expression is 1.

Anuta_ua [19.1K]

Answer: We are given:

During the first 10 days, the stock increases by $0.30 per day.

During the next 10 days, the stock decreases by $0.45 per day.

During the last 10 days, the stock increases by $0.25 per day.

We have to find total amount the stock increase over the first 10 days.

The total amount the stock increase over the first 10 days is:

$0.30 \times 10$

$\$ $3$

Therefore, during the first 10 days the stock was increased by $3.
