$y = \frac{1}{2x^{2} - 4}$
$0 = \frac{1}{2x^{2} - 4}$
$0(2x^{2} - 4) = (2x - 4)(\frac{1}{2x^{2} - 4})$
$0(2x^{2}) - 0(4) = 1$
$0 - 0 = 1$
$0\neq1$

You are the manager of a donut shop. Presently, you sell your donuts for $1.00 each and everyday you sell 500 donuts. However, y

never [62]

Answer: $1.75

Solve for:

What price would result in the most revenue?

Step-by-step explanation:

Let the price of one donut = 1 + 0.05x

Let the # of donuts he can sell = 500 - 10x

Revenue,

$R(x) = (1 + 0.05x)(500 - 10x)$

$R(x) = 500 - 10x + 25x - 0.5x^2$

$R(x) = -10 + 25-0.5(2x)$

$= 15-x\\x=15$

Revenue is maxed when x = 15

When the revenue is maxed,

$Price = 1 + 0.05(15)\\=1 + 0.75\\=1.75$

Therefore the best price for this scenario is $1.75

At a zoo, the lion pen has a ring-shaped sidewalk around it. The outer edge of the sidewalk is a circle with a radius of 11 m. T

OLEGan [10]

Answer:

$\text{Exact area of the sidewalk}=40 \pi\text{ m}^2$

$\text{Approximate area of the sidewalk}=125.6\text{ m}^2$

Step-by-step explanation:

We have been given that at a zoo, the lion pen has a ring-shaped sidewalk around it. The outer edge of the sidewalk is a circle with a radius of 11 m. The inner edge of the sidewalk is a circle with a radius of 9 m.

To find the area of the side walk we will subtract the area of inner edge of the side walk of lion pen from the area of the outer edge of the lion pen.

$\text{Area of circle}=\pi r^2$ , where r represents radius of the circle.

$\text{Exact area of the sidewalk}=\pi*\text{(11 m)}^2-\pi*\text{(9 m)}^2$

$\text{Exact area of the sidewalk}=\pi*\text{121 m}^2-\pi*\text{81 m}^2$

$\text{Exact area of the sidewalk}=40 \pi\text{ m}^2$

Therefore, the exact area of the side walk is $40 \pi\text{ m}^2$

To find the approximate area of side walk let us substitute pi equals 3.14.

$\text{Approximate area of the sidewalk}=40*3.14\text{ m}^2$

$\text{Approximate area of the sidewalk}=125.6\text{ m}^2$

Therefore, the approximate area of the side walk is $125.6\text{ m}^2$ .

What is the answer to 12,8,10,6

maw [93]

Q1) From 12 m to 18 m

It is a percentage increase

Percentage change = (18-12)/12 × 100

= 6/12 × 100

= 50%

Q2) From 27 days to 30 days

It is a percentage increase

Percentage change = (30-27)/27 × 100

= 3/27 × 100

= 11.1%

Q3) From $48.50 to $38.80

It is a percentage decrease

Percentage change = ($48.50 - $38.80)/48.50 × 100

= 9.7/48.50 × 100

= 20%

Q4) From 25 lb to 12 lb

It is a percentage decrease.

Percentage change = 25-12/25 ×100

= 13/25 × 100

= 52%

Q5) from 10mm to 3mm

it is a percentage decrease.

Percentage change = (10-3)/10 ×100

= 7/10 × 100

= 70%

Q6) From $875 to $1000

It is a percentage increase.

Percentage change = (1000-875)/875 × 100

= 125/875 ×100

= 14.3%

Q7) from $18.1 to $22.50

It is a percentage increase

Percentage change = (22.50-18.10)/18.10 × 100

= 4.4/18.10 × 100

= 24.3%

Q8) From 32 people to 3040 people

It is a percentage increase.

Percentage change = (3040-32)/32 × 100

= 3008/32 × 100

= 9400%

Q9) From 28 stray cats to 5 stray cats.

It is a percentage decrease.

Percentage change =(28-5)/ 28 × 100

= 23/28 × 100

= 82%

Q10) From 12 words to 90 words.

It is a percentage increase.

Percentage change = (90-12)/12 × 100

= 78/12 ×100

= 650%

Q11) From 47 mph to 35 mph

It is a percentage decrease

percentage change = (47 - 35)/47 × 100

= 13/47 × 100

= 25.5%

Q12) From 8 computers to 15 computers

It is a percentage increase

percentage change = (15-8)/8 × 100

= 7/8 × 100

= 87.5%
