Definition:

Hyperopia, or farsightedness, is a common vision problem. It affects up to a fourth of the population. The people diagnosed with this can see far away objects very well but have trouble seeing things close to them.

Symptoms:

Farsighted people sometimes have headaches or eye strain and may squint or feel fatigued when performing work at close range. If you get these symptoms while wearing your eyeglasses or contact lenses, you may need an eye exam and a new prescription.

What causes this?

This vision problem occurs when light rays entering the eye focus behind the retina, rather than directly on it. The eyeball of a farsighted person is shorter than normal.

Many children are born farsighted, and some of them "outgrow" it as the eyeball lengthens with normal growth.

Sometimes people confuse hyperopia with presbyopia, which also causes near vision problems but for different reasons.

The starting line for a race in Fulton is 1.2 miles from the finish line. On a map of the course, the starting and finish lines

topjm [15]

Answer:

1 inch = 0.3 miles

Step-by-step explanation:

We basically want to know how many miles in real life 1 inch on the map represents. We already know that 4 inches on the map corresponds to 1.2 miles in real life, but we need to find what 1 inch on the map corresponds to. Let's make a proportion:

$\frac{4}{1.2} =\frac{1}{x}$

Cross-multiply:

4x = 1.2

Divide by 4 from both sides:

x = 1.2/4 = 0.3

Thus, the scale is 1 inch = 0.3 miles.

Hope this helps!

Bob's Skate Shop had a profit of $3,563 during the month of August. The company models its profit using where x is the number of

CaHeK987 [17]

Answer:

The number of skateboard company sell during the month of August = 55

Step-by-step explanation:

We have given,

Profit function for Bob, P = x²+ 10x - 12

Bob's profit during August month is $3,563

That means, P = $3,563

We can use the profit formula given for Bob's profit:

P = x² + 10x - 12

Plug P =$3,563 in above formula.

i.e 3,563 = x² + 10x - 12

or 0 = x² + 10x -12 - 3,563

or 0 = x² + 10x - 3575

or x = 55, -65

Since number of skate boards can not be negative.

So we consider x= 55

Hence the number of skateboard company sell during the month of August = 55.

2x^2 + 2y^2 - 8x + 10y + 2 =0

A circle of radius r centered at (a, b) has equation

(x - a)² + (y - b)² = r ²

To get the given equation in this form, complete the square with respect to both x and y.

2x² - 8x = 2 (x² - 4x)

2x² - 8x = 2 (x² - 4x + 4 - 4)

2x² - 8x = 2 ((x - 2)² - 4)

2x² - 8x = 2 (x - 2)² - 8

2y² + 10y = 2 (y² + 5y)

2y² + 10y = 2 (y² + 5y + 25/4 - 25/4)

2y² + 10y = 2 ((y + 5/2)² - 25/4)

2y² + 10y = 2 (y + 5/2)² - 25/2

So we have

2x² + 2y² - 8x + 10y + 2 = 0

2 (x - 2)² - 8 + 2 (y + 5/2)² - 25/2 + 2 = 0

2 (x - 2)² + 2 (y + 5/2)² = 37/2

(x - 2)² + (y + 5/2)² = 37/4

(x - 2)² + (y + 5/2)² = ((√37)/2)²

which means this circle has radius (√37)/2 and center (2, -5/2).
