15 +51 = 66 meters total
66 /2 = 33 seconds
and that is your answer
The person will reach to the seventeenth in 33 seconds.
Given that,
The lowest parking level is 15 meters below street level, and the seventeenth story is 51 meters above street level.
To determine how long, in seconds, could a person ride the elevator when starting from the lowest level.
Speed is defined as when an object is in motion, the distance covered by that object per unit of time is called speed.
Here,
Total height to cover = height of lowest parking to street level + height of 17 stories from street level.
Total height = 15 + 51
Total height = 66 meters
Time to reach to the 17th story
Speed = distance / time
2 = 66 / time
time = 66 / 2
Time = 33 seconds
Thus, the person will reach to the seventeenth in 33 seconds.

A deck of cards is shuffled. what is the chance that the top card is the king of spades and the bottom card
The probability of getting the king of spades as the top card and the bottom card of a shuffled deck depends on whether the cards are picked with or without replacement.
Explanation:The probability of getting the king of spades as the top card and the bottom card of a shuffled deck depends on whether the cards are picked with or without replacement. If the cards are picked without replacement, the probability will be different than if they are picked with replacement.
If the cards are picked without replacement, the probability of getting the king of spades as the top card is 1/52. This is because there is only one king of spades in a deck of 52 cards. After the king of spades is picked as the top card, there are 51 cards left in the deck. The probability of getting the king of spades as the bottom card is also 1/51 because there is only one king of spades left in the deck.
If the cards are picked with replacement, the probability of getting the king of spades as the top card is still 1/52, but the probability of getting the king of spades as the bottom card is also 1/52. This is because each card is put back into the deck and reshuffled before the next card is picked, so the probabilities for each card remain the same.

Type the number 1340000 in scientific notation. express your answer using scientific notation.
To convert the number 1,340,000 into scientific notation, move the decimal point 6 places to the left to get 1.34, then place this as an exponent on 10 to get 1.34 x 10^6.
Explanation:In scientific notation, large numbers are simplified by moving the decimal point to the left until we have a number between 1 and 10. We then use an exponent on 10 to indicate how many places the decimal point has been moved. If you take a look at the number 1,340,000, the decimal point is technically at the end of the number right now. In order to express this number in scientific notation, we move the decimal point 6 places to the left, which gives us 1.34. The number of places we moved the decimal point to the left becomes the exponent on 10. Therefore, 1,340,000 in scientific notation is 1.34 x 10^6.

Find the parabola with equation y = ax^2 + bx whose tangent line at (2, 4) has equation y = 8x − 12.
We want to get a quadratic equation by knowing its tangent line at a point. Remember that the tangent line is given by the derivative of the equation.
We will find that the parabola is:
y = 3*x^2 - 4*x
We start with the tangent line:
y₂ = 8*x - 12
The slope of this tangent line is equal to the derivative of our parabola evaluated in x = 2.
Our parabola is y = a*x^2 + b*x
Derivating we get:
y' = 2*a*x + b
Then we have:
2*a*2 + b = 8
And we also know that our parabola passes through the point (2, 4), then we must have:
4 = a*2^2 + b*2
Then we have a system of equations:
2*a*2 + b = 8
4 = a*2^2 + b*2
First we can simplify the equations:
4*a + b = 8
4 = 4*a + 2*b
We can isolate 4*a in the first equation to get:
4*a = 8 - b
Now we can replace it in the second equation:
4 = (8 - b) + 2*b
4 = 8 + b
4 - 8 = b
-4 = b
Now that we know the value of b, we can use
4*a = 8 - b
4*a = 8 + 4 = 12
a = 12/4 = 3
Then the equation of the parabola is:
y = 3*x^2 - 4*x

You bought a magazine for $6 and some notepads for $3 each. You spent a total of $18. How many notepads did you buy?
To find the number of notepads bought, we can set up an equation by subtracting the cost of the magazine from the total cost and equating it to the cost of the notepads. By solving the equation, we find that you bought 4 notepads.
Explanation:To solve this problem, we can start by setting up an equation. Let's assume the number of notepads bought is 'x'. We know the magazine cost $6, so the cost of the notepads is $18 - $6 = $12. Since each notepad costs $3, the equation becomes 3x = 12. To find the value of 'x', we can divide both sides of the equation by 3. So, x = 12/3 = 4.
Therefore, you bought 4 notepads.

Which function represents g(x), a reflection of f(x) =1/2(3)x across the y-axis?
Answer:
The required function - [tex]g(x)=\frac{1}{2}(3)^{-x}[/tex]
Step-by-step explanation:
Given : Function represents g(x), a reflection of [tex]f(x) =\frac{1}{2}(3)^x[/tex] across the y-axis
To find : Which function represents the g(x)?
Solution :
The function [tex]f(x) =\frac{1}{2}(3)^x[/tex]
The function f(x) reflected across y-axis to form g(x)
The reflection of the point (x,y) across the y-axis is the point (-x,y).
f(x,y)→f(-x,y) , the graph of f(x) is reflected across y-axis.
Let [tex]y=\frac{1}{2}(3)^x[/tex]
After reflection across y-axis is
[tex]g(x)=\frac{1}{2}(3)^{-x}[/tex]
The required function.

A play was attended by 173 people. Adult tickets were $5 each and children paid $3 for each ticket the total revenue was $703. How many of each kind of ticket were sold?
Answer: 81 children and 92 adults
Step-by-step explanation:
To solve the exercise, check the data we have from the question:
Total people: 173
Adult tickets price: $5
Children tickets price: $3
Total revenue: $703
We need to know how many of each kind of ticket were sold. To do so, we can show the data as two equations:
Equation 1:
[tex]TotalRevenue = Adults*5 + Children*3[/tex]
[tex]703=5a+3c[/tex]
Equation 2:
[tex]a+c=173[/tex]
Where a represents adults who attended the event and c represents children who attended the event. We can replace one of the unknown quantities following:
[tex]a=173-c[/tex]
[tex]703=5(173-c)+3c[/tex]
Solving:
[tex]703=865-5c+3c[/tex]
[tex]5c-3c=865-703[/tex]
[tex]2c=162[/tex]
[tex]c=81[/tex]
Then, we replace c on equation 2:
[tex]a=173-81[/tex]
[tex]a=92[/tex]
