Una autopista atraviesa un cerro mediante un túnel que tiene forma de arco parabólico, tiene 4 metros de altura ¿Cuál es la altura máxima que puede tener un camión de transporte que tiene 2 metros de ancho para pasar sin atorarse?

Answers

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.

∠ and ∠ are supplementary angles. If ∠ = (2 − 30)° and ∠ = 4, find the measure of the larger angle

Answers

Answer:

We get ∠A =40° and ∠B = 140° and ∠B = 140° is measure of larger angle

Step-by-step explanation:

we have  ∠A = (2x − 30)° and ∠B = 4x, and we need to find measure of larger angle. And ∠A and ∠A are supplementary angles.

If the angles are supplementary there sum is equal to 180° i.e A + B = 180°

So,  First we have to find the value of x. and then we can determine larger angle.

We know: ∠A + B = 180

2x-30+4x=180

6x-30=180

6x=180+30

6x=210

x=210/6

x=35

So, value of x is x=35

Now finding A and B

∠A = (2x − 30)°

∠A = (2(35) − 30)°

∠A = (70 − 30)°

∠A =40°

and ∠B = 4x

∠B = 4(35)

∠B = 140°

So, we get ∠A =40° and ∠B = 140° and ∠B = 140° is measure of larger angle

Answer:

i hope that you find this helpful! :D

The missing step for solution of the expression is,

⇒ Divide both sides of the equation by 10.4.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Now, We have been given an expression:

2.3 + 8(1.3x - 4.75) = 629.9  

Hence, We will solve the above equation for x as;

First distribute the parenthesis over 8 we get:

2.3 + 10.4x - 38 = 629.9

Now, subtract 2.3 on right hand side of the above equation we get:

10.4x - 38 = 629.9 - 2.3

10.4 x = 627.6 + 38

10.4 x = 665.6

Hence, the last step would be divide by 10.4 to get the value of x

x = 64

Therefore, option 4th is correct.

Answers

Answer:

10t + 400 would be the answer.

Step-by-step explanation:

every hour, there would be 10 gallons added to the pool, so time should be the letter "t" in the equation.

Also, there's already 400 gallons of water existing in the pool, so we need to add 400 gallons.

Therefore, 10t + 400 would be the answer.
