A tower has a revolving restaurant 840 feet above the ground. The restaurant makes a complete revolution every 60 minutes. While a visitor was at the tower, the restaurant rotated through 126°. How long was the visitor at the tower? The visitor was at the tower for minutes.
Answer: 21 minutes
Step-by-step explanation: A complete revolution has 360°. The tower rotates completely after 60 minutes, which means:
360° - 60 min
The restaurant rotated 126° while the visitor was at the tower, so using proportionality rule:
360° - 60 min
126° - t min
[tex]t=\frac{126*60}{360}[/tex]
[tex]t=\frac{126}{6}[/tex]
t = 21
The visitor was at the tower for 21 minutes.

How does the graph of g(x) = −(x − 2)4 compare to the parent function of f(x) = x4?
g(x) is shifted 2 units to the right and reflected over the x-axis.
g(x) is shifted 2 units to the left and reflected over the x-axis.
g(x) is shifted 2 units to the right and 1 unit up.
g(x) is shifted 2 units to the right and 1 unit down.
Given:
[tex]g(x)=-(x-2)^4[/tex]
[tex]f(x)=x^4[/tex]
To find:
How does the graph of g(x) compare to the parent function of f(x)?
Solution:
The translation is defined as
[tex]g(x)=kf(x+a)+b[/tex] .... (1)
Where, k is stretch factor, a is horizontal shift and b is vertical shift.
If 0<k<1, then the graph compressed vertically by factor k and if k>1, then the graph stretch vertically by factor k.
If k<0, then graph of f(x) reflected over x-axis.
If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.
If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.
We have,
[tex]f(x)=x^4[/tex]
[tex]g(x)=-(x-2)^4[/tex]
So,
[tex]g(x)=-f(x-2)[/tex] ...(2)
From (i) and (ii), we get
[tex]k=-1<0[/tex], it means g(x) reflected over the x-axis.
[tex]a=-2<0[/tex], it means g(x) shifted 2 units to the right .
Therefore, the correct option is A.
Answer:
A. g(x) is shifted 2 units to the right and reflected over the x-axis.

Help me this is due at 12:00 :(:(:(
Answer:
3/5, -12 12/15, 51/125
Step-by-step explanation:
just did it
Answer:
3/5; -12 12/25; 51/125
Step-by-step explanation:
Write the first one just like you would say it. You would read 0.6 as six tenths, therefore your answer is 6/10, but don't forget to simplify to 3/5.
Next, you have -12.48. -12 is going to be your whole number. However, you still have 0.48 left so you would write it just how you would say it. You would say it as forty-eight hundredths which is why you would write it as 48/100. Now you just have to simplify it into 12/25. Thus, your final answer would be -12 12/25.
Finally, you have 0.408 which is read as four hundred eight thousandths. Your fraction would then be 408/1000. Now simplify to 51/125.

Mike wants to save $1,750 in the next 12 months. He plans to save $150 each month for the first 11 months. Part A What is the total amount of money Mike will save during the first 11 months if he saves $150 each month? Enter your answer in the box. $ Part B Mike plans to save the same amount in the 12th month as in each of the other months. Will Mike be able to save $1,750 in the 12 months? Enter numbers in the boxes to solve the problem. Since $1,750 – $ = , Mike will need to save $ in the 12th month. Since $ is less than $150, he will be able to reach his goal.
Answer:
A. $1,650
Mike will reach his goal if he saved $100 in the 12th month if he has been saving $150 for the first 11 months
Step-by-step explanation:
Mike wants to save $1,750 in the next 12 months.
He plans to save $150 each month for the first 11 months.
A. Total amount of money Mike will save during the first 11 months if he saves $150 each month is
$150 × 11 months
= $1,650
B. If Mike plans to save the same amount in the 12th month ($150) as in each of the other month
= $150 × 12 months
= $1,800
He will be able to save $1,750 if Mike saved the same amount in the 12th month
In the 12th month, Mike only needs to save $100 if he has saved $150 in the first 11 months in order to reach his goal

Laura corto un trozo de tela cuadrada para un mantel. Luego se dio cuenta de que ese trozo no alcanzava a cubrir la superficie pues, había un error de medidas. Pará arreglarlo le agrego dos prendas haciendo el el mantel ahora sea rectangular, su largo mide 50 cm mas y su ancho 3o cm más que las medidas del mantel original. Si el nuevo mantel cubre 16800 cm2 ¿cuál es la medida del lado del primer mantel y cuantos cm2 cubría?
Answer:
La medida del lado del primer mantel es 90 centímetros.
Primer mantel cubría un área de 8100 centímetros cuadrados.
Step-by-step explanation:
Sea [tex]x[/tex] la longitud del lado del mantel original, cuya forma es cuadrada y está medida en centímetros. Al agregarse dos prendas, se obtiene un rectángulo, cuya área ([tex]A[/tex]), medida en centímetros cuadrados, se halla mediante la siguiente fórmula:
[tex]A = w\cdot l[/tex] (Eq. 1)
Donde:
[tex]w[/tex] - Ancho, medido en centímetros.
[tex]l[/tex] - Largo, medido en centímetros.
Si [tex]A = 16800\,cm^{2}[/tex], [tex]l = x+50\,cm[/tex] y [tex]w = x+30\,cm[/tex], tenemos el siguiente polinomio de segundo orden:
[tex]16800 = (x+50)\cdot (x+30)[/tex]
[tex]16800 = x^{2}+80\cdot x +1500[/tex]
[tex]x^{2}+80\cdot x -15300 = 0[/tex]
Por la fórmula de la Cuadrática tenemos que las raíces del polinomio son:
[tex]x_{1} = 90\,cm[/tex], [tex]x_{2} = -170\,cm[/tex].
Solamente la primera raíz es una solución físicamente razonable. Entonces, la medida del lado del primer mantel es 90 centímetros.
Ahora, el área del primer mantel es:
[tex]A = (90\,cm)^{2}[/tex]
[tex]A = 8100\,cm^{2}[/tex]
Primer mantel cubría un área de 8100 centímetros cuadrados.
3 more than eight times a number is equal to 19

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using this equation, find out the time at which the rocket will reach its max, to the nearest 100th of a second. y=-16x^2+263x+92
Answer:
8.39 seconds
Step-by-step explanation:
Given the equation which models the height of a rocket:
y=-16x^2+263x+92
Time taken to reach maximum height ; = total total time of flight / 2
Total time of flight is obtained at h = 0
Hence +,
y=-16x^2+263x+92 ; y = 0
-16x^2+263x+92 = 0
Using the Quadratic equation solver :
X = 16.78 or x = -0.3466
Time can't be negative
Hence, total time of flight= 16.78
Therefore, time taken to reach maximum height :
Total time of flight / 2
= 16.78 / 2
= 8.39 seconds
