Work Shown:

f(x) = x^3
f(3) = 3^3 ... replace every x with 3
f(3) = 27

g(x) = 4*x + 3
g(x) = 4*( x ) + 3
g(f(3)) = 4*( f(3) ) + 3 ... replace every x with f(3)
g(f(3)) = 4*( 27 ) + 3 ... replace f(3) with 27
g(f(3)) = 108 + 3
g(f(3)) = 111

The difference between Alan's and Bea's age is three years. The sum of their ages is twenty-seven years. How old are they if-
A. Alan is older than bea?
B. Bea is older than Alan?

Answers

Alright. Take x as Alan's age, and y as Bea's age. We can start writing equations; from the first sentence, we find that x - y = 3. From the second sentence, x + y = 27. Adding the two equations, gives 2x = 30. Thus, x is 15, and it follows, that y = 15 - 3, or 12. So for A, Alan is 15, and Bea is 12, and for B, Bea is 15, and Alan is 12.

a - b = 3
a + b = 27
--------------add
2a = 30
a = 30/2
a = 15 <=== alan is 15

a + b = 27
15 + b = 27
b = 27 - 15
b = 12 <=== bea is 12

A restaurant earns $1240 on Friday and $921 on Saturday. Write and solve an equation to find the amount xx (in dollars) the restaurant needs to earn on Sunday to average $1000 per day over the three-day period. Write your equation so that the units on each side of the equation are dollars per day

Answers

Alright, to average 1000 per day over 3 days, we have 1000*3=3000 dollars. Since we already have 2 days, we do 3000-1240-921=839

Answer:

The restaurant needs to earn $839 on Sunday.

Step-by-step explanation:

Consider the provided information.

Let $x needs to earn on Sunday, to average $1000 per day .

It is given that the average earn should be $1000

[tex]Average=\frac{\text{Sum of observations}}{\text{Total number of observation}}[/tex]

[tex]Average= \frac{1240+921+x}{3}[/tex]

[tex]Average= \frac{2161+x}{3}[/tex]

The average should be $1000, so substitute 1000 for average and solve for x.

[tex]\frac{2161+x}{3} =1000\\\\ 2161+x=3000\\\\x=3000-2161\\\\x=839[/tex]

Thus, the restaurant needs to earn $839 on Sunday.

The required equation is [tex]\frac{1240+921+x}{3}=1000[/tex].

Martin is logging the number of strikes he bowls per hour. He has determined the function to be f(x) = 2x + 5, where x represents hours and f(x) represents the number of strikes he has bowled. Which of the following options describes the restrictions to the domain and range correctly?
Domain, nonnegative values; range, values greater than −2.5
Domain, nonnegative values; range, values greater than or equal to 5
Domain, nonnegative values; range, values less than −2.5
Domain, nonnegative values; range, values less than or equal to 5

Answers

domain (x values) are non-negative values
range (f(x) values are : values greater then or equal to 5

Answer:

B. Domain, nonnegative values; range, values greater than or equal to 5

Step-by-step explanation:

Basically, domain is the set of values that x can take and range is the set of values that the result of f(x) can be.

Since x is the time Martin spends bowling, it cannot be negative. The least he can bowl is zero hours, so x cannot be a negative number.

For the lowest x can be (zero), f(x) is calculated as:

f(x) = 2(0)+5 = 0+5 = 5

For higher values of x, the equation can only yield higher results because the 2 that is multiplying it is positive. Multiplying a two positive numbers (2 and x, which cannot be negative) will always give a positive number. In other words, f(x) is directly proportional to x because its coefficient 2 is positive, which means that when x grows, f(x) grows.

This means that f(x) can never be lower than 5.

The best description is, then, nonnegative values for the domain and values greater or equal to 5 for the range.

Jillian’s school is selling tickets for a play. The tickets cost $10.50 for adults and $3.75 for students. The ticket sales for opening night totaled $2071.50. The equation 10.50a + 3.75b = 2071.50, where a is the number of adult tickets sold and b is the number of student tickets sold, can be used to find the number of adult and student tickets. If 82 students attended, how may adult tickets were sold?

adult tickets

Answers

168 adult tickets were sold

Answer: There are 168 adult tickets that were sold.

Step-by-step explanation:

Let the number of adult tickets were sold be 'a'.

Let the number of student tickets were sold be 'b'.

Since we have given that

The ticket sales for opening night totaled as

[tex]10.50a+3.75b=2071.50[/tex]

And the number of students attended = 82

so, b = 82

So, we will put the value of b in the above equation:

[tex]10.50a+3.75\times 82=2071.50\\\\10.50a+307.5=2071.50\\\\0.50a=2071.50-307.5\\\\10.50a=1764\\\\a=\dfrac{1764}{10.50}\\\\a=168[/tex]

Hence, there are 168 adult tickets that were sold.

The next train will arrive in 32 minutes and 30 seconds.

In how many seconds will the next train arrive?

____Seconds

Answers

So the first thing you need to do is convert the 32 minutes into seconds. You do this by multiplying 32 by 60. So 32x60=1920. Then you need to add the 30 to the 1920 so the answer would be 1,950 seconds.

Final answer:

You can convert time from minutes to seconds by multiplying the number of minutes by 60. Therefore, if the train is due in 32 minutes and 30 seconds, the train will arrive in 1950 seconds.

Explanation:

To answer your question, we need to understand that 1 minute is equal to 60 seconds.

So, if the train arrives in 32 minutes, then it will arrive in 32 minutes * 60 seconds per minute, which equal 1920 seconds. And we have additional 30 seconds. So, the total time the train will arrive in is 1920 + 30 = 1950 seconds.

Answers

A ball is launched into the sky at 19.6 feet per second from a 58.8 meter tall building. "

Is that a typo, or a real mixture of units?

The equation is only good if the launch speed is actually 19.6 m/s, so I'll assume that.

It will strike the ground when the ball's height = 0 m !!!

-4.9t² +19.6t + 58.8 = 0

You can always use the "quadratic formula" if you want to, but ...

This set of numbers is beloved by physics teachers everywhere. Everything divides by -4.9

t² - 4t -12 = 0

...and factorizes easily:

(t + 2)(t - 6)

So t = 6 or t = -2 Disregard the negative solution.

The ball will strike the ground at t = 6 seconds

Determined whether the graphs of each pair of equations are parallel, perpendicular or neither

Answers

One way to look at it would be to solve for y - if what x is multiplied by is the same for both sides, they're parallel. If one is the negative reciprocal (e.g. for 5/6 the reciprocal is 6/5 and the negative reciprocal is therefore -6/5) of another, they're perpendicular and if they're neither they're neither.Solving for y in x+5y=4, we can subtract x from both sides to get 5y=-x+4. Next, we can divide both sides by 5 to get -x/5+4=y. Since -x/5=(-1/5)(x) and -1/5 is not the negative reciprocal of 5/6 as established earlier, they are neither

During a storm, why do you see the flash of lightning before you hear the roar of thunder? What would it mean if you saw the flash of lightning and heard the roar of thunder at the same time? What would it mean if there were many seconds in between the flash of lightning and the roar of thunder?

Answers

The speed of light is faster than the speed of sound. So that's why you see a flash of lightning before the roar of thunder. If you heard it at the same time as you saw it, well I will be praying for you. It would literally be exactly where you are. If you hear the thunder a long time after the flash, it means the lightning is far away.

T/5=miles away when T is time from the strike of lightning to hearing thunder

Final answer:

You see lightning before hearing thunder due to the faster speed of light compared to sound. A simultaneous occurrence suggests the lightning is very close, while a delay indicates distance, with every five seconds equaling approximately one mile.

Explanation:

During a storm, you see the flash of lightning before you hear the roar of thunder because light travels much faster than sound. Lightning, a massive discharge of electricity, heats and expands the air rapidly, creating the sound of thunder. The difference in the travel speeds of light (3 × 10⁸ meters per second) and sound means that we perceive these events at different times.

If you saw the flash of lightning and heard the roar of thunder at the same time, it would mean that the lightning strike occurred very close to your location, practically overhead. Conversely, a noticeable delay between the flash of lightning and the sound of thunder indicates that the lightning strike is farther away. Each 5-second gap between seeing lightning and hearing thunder equates to approximately one mile distance from the lightning strike.

To estimate the distance of a storm, you only need to know the speed of sound, as the speed of light is so fast that the time it takes for light to reach you is negligible for this calculation. This method of estimating distance helps understanding the physical phenomena and ensuring safety during storms.
