Given the information below, write the equation in Standard Form.

Sergio [31]

Answer:

The standard form of the equation of the parabola is (y + 2)² = 8 (x - 3)

Step-by-step explanation:

The standard form of the equation of a parabola is (y - k)² = 4p (x - h), where

The vertex of the parabola is (h , k)
The focus is (h + p, k)

∵ The vertex of the parabola is (3 , -2)

∴ h = 3 and k = -2

∵ The focus is (5 , -2)

∴ h + p = 5

- Substitute h by 3 to find p

∵ 3 + p = 5

- Subtract 3 from both sides

∴ p = 2

∵ The standard form of the equation of the parabola is (y - k)² = 4p (x - h)

- Substitute the values of h , k , and p in the equation

∴ (y - -2)² = 4(2) (x - 3)

∴ (y + 2)² = 8 (x - 3)

The standard form of the equation of the parabola is (y + 2)² = 8 (x - 3)

1.
$A=\dfrac{14\cdot5}{2}=\dfrac{70}{2}=35$

2. Look at the picture.

$A_I=8\cdot13=104\ in^2\\\\h=19-13=6\ in\\\\A_{II}=\dfrac{8\cdot6}{2}=\dfrac{48}{2}=24\ in^2\\\\A=104+24=128\ in^2$

Before being simplified, the instructions for computing income tax in Country R were to add 2 percent of one’s annual income to

Vedmedyk [2.9K]

Answer:

Option C)

$50 + \dfrac{I}{40}$

Step-by-step explanation:

We are given the following in the question:

I is the annual income of a person in a country R

2 percent of one’s annual income =

$\dfrac{2}{100}\times I = 0.02I$

1 percent of one’s annual income =

$\dfrac{1}{100}\times I = 0.01I$

Average of 100 units of Country R’s currency and 1 percent of one’s annual income.

$=\dfrac{0.01I + 100}{2}$

Income tax =

2 percent of one’s annual income + Average of 100 units of Country R’s currency and 1 percent of one’s annual income.

$= 0.02I + \dfrac{100+0.01I}{2}\\\\=50 + \dfrac{0.04I + 0.01I}{2}\\\\=50 + \dfrac{0.05I}{2}\\\\= 50 + \dfrac{I}{40}$

Thus, income tax is given by

Option C)

$50 + \dfrac{I}{40}$
