Answer:

supongo que < 3m

Step-by-step explanation:

el túnel tiene forma de arco parabólico, pero no aclara qué coeficiente tiene el término [tex]x^{2}[/tex], ej: si es  -[tex]x^{2}[/tex],  ó    -0.5 [tex]x^{2}[/tex], ó -0.1 [tex]x^{2}[/tex], ...  

Suponiendo que tuviese coeficiente -1, entonces la ecuación del puente es:

f(x) = -[tex]x^{2}[/tex] + 4

Tomamos el valor de f(x=1) = f(x=-1), porque suponiendo que el camión va por el centro del túnel, y teniendo 2m de ancho, queda 1m hacia cada lado:

f(x=1) = f(x=-1)  = 3

Con lo cual si el camión tiene 3m de alto choca con la curva parabólica que forma el túnel.

Step-by-step explanation:

You know that he spent 1/3 of his earnings, and then 1/4. After this, he has $28.90. You can write the equation like this:

1/4(x * 1/3) = $28.90.

If you need to solve it:

1/4 * 1/3x = 28.90

1/12x = 28.90

x = 346.80

Answer:

The equation of the  perpendicular line is 2 x + y + 1 =0

Step-by-step explanation:

Step(i) :-

Given equation of the line  2y = x - 18

                                      x - 2y - 18 =0

The equation of the perpendicular line to the given line

                      b x - ay +k=0

                     -2 x - y + k =0  this line is passing through the point ( 0 , -1)

                ⇒  0 -(-1) + k=0

                ⇒ 1+k =0

               ⇒  k = -1

Step(ii):-

The equation of the line is perpendicular to the line

              -2x - y - 1 =0

              2 x + y + 1 =0

Conclusion:-

The equation of the  perpendicular line to the given  line  2 x + y + 1 =0

The required equation of the line [tex]l_1[/tex]  is perpendicular line [tex]l_2[/tex] is 2x + y +1 = 0

Given ,

The equation of the line [tex]l_1[/tex] is Y = [tex]-\frac{1}{2} ( X- 18 )[/tex]

We have to find ,

The equation of line which perpendicular to [tex]l_1[/tex] and intersects the Y-axis at (0, -1).

According to the question,

[tex]Y = \frac{-1}{2} (X - 18)[/tex]

2Y = -1 ( X - 18)

2Y = -X + 18

2Y + x - 18 = 0

Then , the given line is perpendicular to the line [tex]l_1[/tex] to line [tex]l_2[/tex]

b  = 2 , a = 1 ,

bx - ay + k = 0

2x - 1y + k = 0

The intersection point the Y- axis  ( 0 , -1 )  

2(0) - 1(-1) + k = 0

0 + 1 + k = 0

k = -1

Put the value of k in equation and write the equation at Y - axis

-2x -y -1 = 0

The required line is 2x+y+1 = 0

The required equation of the line [tex]l_2[/tex] is perpendicular line [tex]l_1[/tex] is 2x + y +1 = 0 .

The answer is y= 5/4x+1

Step-by-step explanation:

y=mx+b

-4=5/4(-4)+b

-4=-5+b

+5 +5

1=b

So the equation of the line that passes through the point (-4,-4) and has a slope of 5/4 is y=5/4x+1 .

Step-by-step explanation:

Answer:

1) At least one (the 11th) student is 23 (years old), Must be true

2) Some students are younger than 15 Could be true

Step-by-step explanation:

1) The given parameters are;

The number of student in the class = 21

The median age of the student = 23

The age of the oldest student = 29

Therefore, given that the median age = The age of the (n + 1)/2 th student

Where;

n = The number of student in the class = 21

∴ The median age = The age of the (21 + 1)/2 th = 11 th student, when the age of the students are arranged in increasing order, therefore, we have;

At least one (the 11th) student is 23 (years old), Must be true

2) Given that there are 10 students with ages equal to or lower than the  median age, and the difference between the median age and the age of the oldest student = 29 - 23 = 6 years, we have;

Some students are younger than 15 Could be true

162 5th term

Step-by-step explanation:

Answer:

5th term =162

Step-by-step explanation:

It is a geometric progression whose nth term = ar^n-1

Where a = 1st term =2

r=ratio of two term= -6/2=-3

n =nth term

So 5th term= 2x-3^5-1

=2x-3^4

=2x81=162 answer

Answer:

42.1 degrees

Step-by-step explanation:

- since we have a opposite/hypotenuse ratio, that means we used sin x = o/h

- this means, sin x = 0.67

so, x = [tex]sin^{-1[/tex](0.67)  {sin inverse}

x = 42.06 degrees, i rounded it up to 42.1 but its up to you (or according to the question)

Answer:

Answer:

  $82.28

Step-by-step explanation:

Being married puts Celeste on the right half of the table. Four allowances put her in the 5th section down, where 4 is in the left-most column. Her weekly wage of 1298 puts her wage between 923.30 and 2068.20, so on the second line in that section.

The table tells you to subtract $612.37 from Celeste's weekly wage, then multiply the result by 12% to find her withholding. Doing that, we find the withholding to be ...

  (1298.00 -612.37) × 0.12 = $82.28 . . . . rounded up to the nearest cent

The withholding tax applicable to Celeste's earnings is $82.28.
