The main cable of a suspension bridge forms a parabola, described by the equation y = a(x - h)2 + k, where y is the height in fe
nirvana33 [79]
Refer to the diagram shown below.

When x = 30 ft, the cable is at 15 ft, therefore y(30) = 15.
That is,
a(30 - h)² + k = 15            (1)

Also, because the distance between the supports is 90 ft, therefore
y(0) = 6 ft, and y(90) = 6 ft
That is,
a(-h)² + k = 6                 (2)
a(90 - h)² + k = 6          (3)

From (2) and (3), obtain
a(90 - h)² = ah²
90² - 180h + h² = h²
180h = 90²
h = 45 ft.

From (1) and (2), obtain
225a + k = 15
2025a + k = 6

Therefore
1800a = -9
a = - 0.005
k = 15 - 225(-0.005) = 16.125 ft

Answer:
The equation for the cable is
y = - 0.005(x - 45)² + 16.125 

A graph of the solution verifies that the solution is correct.

Find the value of each variable in each parallelogram.
svp [43]

Answer:

a=109° b=71°

Step-by-step explanation:

All the angles in a parallelogram add up to 360. There are a few rules:

The opposite angles are congruent.

Consecutive angles are congruent.

We can apply these rules here.

71 is opposite to b

and a is consecutive to 71 so we can put together these equations.

180=71+a

71=b

we can simplify to get the answers

the end

Can anyone help me answer this question (find x)? (15 points)
Greeley [361]

Answer:

The answer to your question is x = 6

Step-by-step explanation:

Process

1.- We can prove that the triangles are congruent.

Two angles measure the same 23°

Two sides measure the same 9

Two angles measure the same the are vertical angles

The third angle measure the same

From this information, we conclude that the triangles are congruent  ASA

2.- If the triangles are congruent then x = 6, the sides are congruent

Answer:

6.12

Step-by-step explanation:

tan 27≈0.51

Know that tan=\frac{opposite}{adjacent}

0.51=\frac{x}{12}

Multiply 12 on both sides

6.12=x
