A parabolic archway is 12 meters high at the vertex. at a height of 10 meters, the width of the archway is 8 meters. how wide is
Virty [35]
To solve this problem you must apply the proccedure shown below:

 1. You have that the <span>parabola is 12 meters high at the vertex and at a height of 10 meters, the width is 8 meter. 

 2. Therefore, you have:

 x^2=-4a(y^2-k)
 4</span>^2=-4a(10-12)
 16=-40a+48
 16=8a
 a=16/8
 a=2

 y=0
 x^2=-8(0-12)
 x^2=96
 x=√96
 x=9.79x2
 x=19.58

 3. Therefore, as you can see, the answer is: 19.58 meters.<span>

Answer: 139°

Reasoning:

Angle 3 and 5 are congruent, so you can put their expressions equal to each other and solve.

14x-1=9x+14

To isolate the x to one side, subtract the 9x from the 14x.

5x-1=14

Now to get the constants on one side, add the 1 to the 14.

5x=15

Now divide both sides by 5 to isolate the x.

5x/5=15/5

x=3

Now that we know that, we can figure out angle 3.

9(3)+14

27+14= 41

Angle 3 = 41°

Now that we know what angle 3 is, we can subtract it from 180° to figure out angle 8 since angle 3 and 8 are supplemtary angles, aka linear pairs.

180°- 41°= 139°

<h3>Double checking your answer:</h3>

41°+139°=180°

N - 4 = 3n + 6<br> Plz help me if possible no pics
levacccp [35]

Answer:

n=−5

Step-by-step explanation:

n−4−3n=3n+6−3n

−2n−4=6

Step 2: Add 4 to both sides.

−2n−4+4=6+4

−2n=10

Step 3: Divide both sides by -2.

−2n /−2 =  10 /−2

n=−5
