A suspension bridge with weight uniformly distributed along its length has twin towers that extend 55 meters above the road surface and are 1200 meters apart. The
cables are parabolic in shape and are suspended from the tops of the towers. The cables touch the road surface at the center of the bridge. Find the height of the
cables at a point 300 meters from the center. (Assume that the road is level.)
The height of the cables is meters.
(Simplify your answer.)

Answers

Answer 1

Answer:

try kopo

Step-by-step explanation:

55+1200+300=1555

Answer 2

Answer:

Step-by-step explanation:

start by graphing it (see picture)

formula for a parabola: y=ax²

using the coordinates (600,55) we get

55=a*600²

a=55/(600²)

so now it's just a matter of plugging in 300 for x

(55/600²)*300²= 13.75

Find the area of the shaded region. Round your answer to the nearest hundredth.

12=side length

The area of the shaded region is about — square units.

How do you find the area of the shaded region? Thank you!

Answers

Answer:

Step-by-step explanation:

Divide 360 by the number of sides in a regular polygon to find θ

θ = 360/5 = 72°

Use law of cosines to find the radius of the circle which equals the common length sides of the isosceles triangle

12² = R² + R² - 2•R•Rcos72

12² = 2R² - 2R²cos72

12² =  2R²(1 - cos72)

R² = 12² / 2(1 - cos72)

R² = 104.1993788...

R = 10.2078...

The height of the isosceles triangle is

h = Rcos(θ/2) = 10.2078cos(72/2) = 8.258291...

The shaded area is the area of the circle minus the area of the pentagon.

A = π(104.1993) - 5(½(12)(8.258291))

A = 327.35200... - 247.74874...

A = 79.6032575...

A = 79.60 units²

The Area of the shaded region is A = 79.60 units²

What is law of Cosine?

A planar triangle's side's square is equal to the sum of the squares of the other sides minus the product of those sides and the cosine of the angle that separates them by two.

Given:

length= 12

So, Divide 360 by the number of sides in a regular polygon

θ = 360/5

θ = 72°

Use law of cosines

12² = R² + R² - 2 x R x Rcos72

12² = 2R² - 2R² cos72

12² =  2R²(1 - cos72)

R² = 12² / 2(1 - cos72)

R² = 104.1993788...

R = 10.2078...

Thus, the height of the isosceles triangle is

h = R cos(θ/2)

   = 10.2078cos(72/2)

   = 8.258291...

and, the shaded area is

A = π(104.1993) - 5(½)(12)(8.258291))

A = 327.35200 - 247.74874

A = 79.6032575

A = 79.60 units²

f inverse of x is equal to the quantity x minus 4 end quantity over the quantity x plus 3 end quantity
f inverse of x is equal to the quantity x minus 3 end quantity over the quantity x plus 4 end quantity

Answers

Answer:

Option B

Step-by-step explanation:

Given function:

f(x) = (x + 3)/(x - 4)

Find its inverse, take f(x) as y and swap x with y

x = (y + 3)/(y - 4)x = (y - 4 + 7) / (y - 4)x = 1 + 7/(y - 4)x - 1 = 7 / (y - 4)y - 4 = 7 / (x - 1)y = 4 + 7 / (x - 1)y = (4x - 4 + 7)/ (x - 1)y = (4x + 3) / (x - 1)

Replace y with f⁻¹(x):

f⁻¹(x) = (4x + 3) / (x - 1)

Correct choice is B

A x is equal to the quantity x plus 3 end quantity over the quantity x minus 4 end quantity where x ­ 4. at x = 0.5, the inverse function f²(-1)(x)  f²(-1)(x) = 0.5

To determine the inverse of the function f(x) = (x + 3) / (x - 4),  to follow these steps:

Replace f(x) with -1, since you're looking for the inverse at the point where f(x) = -1:

-1 = (x + 3) / (x - 4)

Solve for x in terms of -1:

Multiply both sides by (x - 4):

-1 ×(x - 4) = x + 3

Distribute the -1:

-x + 4 = x + 3

Solve for x:

Subtract x from both sides:

4 = 2x + 3

Subtract 3 from both sides:

1 = 2x

Divide by 2:

x = 0.5

a is an absolute value if it is greater than zero. This simply means that an absolute value number will always be greater than zero. This is because absolute value is the distance from 0 on a number line. Keep in mind that distance cannot be negative. For example, look at the numbers 5 and -5. 5 is 5 spaces from 0, and -5 is also 5 spaces from 0, not -5 spaces from 0. Put simply, an absolute value number that is greater than 0, will always be positive.

Step-by-step explanation:

the equation :

(y-3)/(3-3) = (x-8) /(7-8)

(y-3) /0 = (x-8) /(-1)

(-1)(y-3) = 0(x-8)

-y +3 = 0

y = 3

Answer:

y = 3 (Horizontal line)

Step-by-step explanation:

point: (8, 3) and (7, 3)

(y - y1)/(y2 - y1) = (x - x1)/(x2 - x1)

(y - 3)/(3 - 3) = (x - 8)/(7 - 8)

(y - 3)/0 = (x - 8)/(-1)

(-1)(y - 3) = 0

-y + 3 = 0

Step-by-step explanation:

The solution is the ordered pair (x, y) where the lines intersect. The graphs have no scale, so we must assume 1 grid space corresponds to 1 unit.

The first coordinate of the pair is the horizontal distance from the y-axis. Positive is to the right. The second coordinate of the pair is the vertical distance from the x-axis. Positive is up.

68. The point of intersection is 2 left of the origin on the x-axis. x=-2, y = 0.

  (x, y) = (-2, 0)

__

69. The point of intersection is 2 up from the origin on the y-axis: y = 2, x = 0.

  (x, y) = (0, 2)

__

70. The point of intersection is 2 right and 1 down from the origin: x = 2, y = -1.
