42
you multiple 70 to 60
then divide it by 100
60/100=x/70
60×70=4200
4200÷100=42

The equation represents a hyperbola centered at the origin with a directrix of . what is the value of b? 10 16 20 26
Rom4ik [11]

the value of b is = 10.

The equation of a hyperbola is x^2/24^2 - y^2/ (10)^2= 1.

<h3>What is hyperbola?</h3>

The geometric characteristics of a hyperbola or the equations for which it is the solution set characterize it as a particular kind of smooth curve that lies in a plane. Mirror reflections of each other that resemble two infinite bows make up a hyperbola's two connected components or branches.

<h3>What is the general formula for hyperbola?</h3>

The general formula for hyperbola = (x - h)²/a²- (y - k)²/(b)² = 1

<h3>According to the given information:</h3>

x²/24 - y²/(b)² = 1

(x - 0)²/24 - (y -0)²/(b)² = 1

a=24,h=0 and k=0

Now equation of the directrix

x=a²/c...(1)

and we know x=576/26...(2)

Therefore from 1 and 2 we get

24²/c=576/26.

isolate the c so we get,

C=26

C= center of focii

c = √(a² + b³)

c² = a² + b²

b = c² - a²

b = 10

So we get the value of b is 10.

Therefore the equation of a hyperbola is x²/24² - y²/ (10)² =  1.

The original blueprint of a concrete patio has a scale of 2 inches = 3 feet.
lyudmila [28]

Answer:

Scale of the new blueprint: 2 inches = 2.5 feet (or 4 inches = 5 feet)

Width of the new blueprint: 14.4 inches

Step-by-step explanation:

To solve this problem we can use rules of three to find each of the questions: blueprint's new scale and new width.

To find the new scale, we can find the real length of the patio first:

2 inches -> 3 feet

14 inches -> X feet

2/14 = 3/X

X = 21 feet

Now we can use this value to create the new scale:

16.8 inches -> 21 feet

2 inches -> X feet

16.8/2 = 21/X

X = 2*21/16.8 = 2.5 feet

So the new scale is 2 inches = 2.5 feet, or 4 inches = 5 feet

Now, to find the new width of the blueprint, we can do the following rule of three:

14 inches of length -> 16.8 inches of length

12 inches of width -> X inches of width

14/12 = 16.8/X

X = 12*16.8/14 = 14.4 inches
