A diver dives from a 9-foot-high platform with an initial speed of 16 feet per second. The height, h, of the diver can be modeled by the equation ℎ = −162 − 16 + 9, where t represents time in seconds. How long will it be before the diver hits the water?
Answers
This is an example of a quadratic equation. It is in the shape of an upside down parabola.
Our goal is to solve the following equation: 0 = -16x^2 - 16x + 9
To do this, we can use the quadratic formula. The variables are:
a = -16
b = -16
c = 9
It will be: 16 +/- The square root of (-16)^2 - 4(-16)9 all divided by 2(-16).
This will give a positive answer of 0.4 seconds.
Christian is comparing two checking accounts. One has a monthly fee of $7 and a per-check fee of $0.20, and the other has a monthly fee of $8 and a per-check fee of $0.15. What is the minimum number of checks Christian needs to write for the second bank to be a better option? A. 22 B. 21 C. 19 D. 18
Answers
Answer:
Option B. 21
Step-by-step explanation:
Christian is comparing two checking accounts.
First account has monthly fee = $7.00
and a per check fee = $0.20
Second account has monthly fee = $8.00
and a per check fee = $0.15
Now make equation to compare both accounts
7 + 0.20x = 8 + 0.15x
7 = 8 + 0.15x - 0.20x
7 = 8 - 0.05x
7 - 8 = -.05x
-1 = - 0.05x
x = [tex]\frac{1}{0.05}[/tex]
x = 20
On 20th check first account and second account are charged equal.
on 21st check second account would be a better option.

peggy is five years older than peter and susan is two years younger than peter the sum of their ages is 15 years how old is each child
Answers
Peter is 4 years old, Peggy is 9 years old, and Susan is 2 years old.
Let's denote Peter's age as ( P ) years. Based on the given information:
1. Peggy is five years older than Peter, so Peggy's age is ( P + 5 ) years.
2. Susan is two years younger than Peter, so Susan's age is ( P - 2 ) years.
The sum of their ages is given as 15 years:
[tex]\[ P + (P + 5) + (P - 2) = 15 \][/tex]
Now, simplify and solve for \( P \):
[tex]\[ 3P + 3 = 15 \]\[ 3P = 12 \]\[ P = 4 \][/tex]
So, Peter is 4 years old. Using this information, we can find Peggy's age[tex](\( P + 5 \)) and Susan's age (\( P - 2 \)):[/tex]
- Peggy: ( 4 + 5 = 9 ) years old
- Susan: ( 4 - 2 = 2 ) years old
Therefore, Peter is 4 years old, Peggy is 9 years old, and Susan is 2 years old.

Explanation:
The square of any number can be obtained by multiplied the number by itself.
In other words:
square of x = x² = x * x
For the given, we want to get the square of 8. This means that we will multiply 8 by itself.
Therefore:
square of 8 = 8² = 8 * 8 = 64
Hope this helps :)
Answer:
[tex]8^2=8\times 8=64[/tex]
Step-by-step explanation:
We have been given a number. We are asked to find the square of our given number.
We know that the square means a quantity multiplied by itself. When a number (a) is multiplied by itself, we can write that number by raising to second power as: [tex]a\times a=a^2[/tex]
Since we need to find the square of 8, so we can write it as:
[tex]8\times 8=8^2[/tex]
[tex]64=8^2[/tex]
Therefore, the square of 8 is 64.

Step-by-step explanation:
We know that the rate of change of a function f(x) from x=a to x=b is given by :-
[tex]\dfrac{f(b)-f(a)}{b-a}[/tex]
Now, the rate of change for the given table is given by :_
[tex]k=\dfrac{\text{Distance(6)-Distance (4)}}{6-4}\\\\\Rightarrow\ k=\dfrac{390-260}{2}\\\\\Rightarrow\ k=65[/tex]
Hence, the rate of change for the given table is 65 miles per hour.

Answers
y = x + 2
3/2x - 2 = x + 2
Then you can simplify your equation by multiplying both sides by 2 to eliminate the fraction which will give you:
3x - 4 = 2x + 4
Add the -4 to the other side to get 8 and subtract the 2x from the 3x so you have:
x = 8 Now solve for y by substituting your value for x into the other equation:
y = 3/2(8) - 2 Simplify by combining your numbers and you get:
y = 10 Check your answer by substituting y and x into the original equation:
(10) = (8) - 2
Correctly done! So your answers are x = 8 and y = 10

There are 450 seats in the lower level of a concert hall with b balcony seats in upper level so far 170 tickets have been sold which Is 1/5 of the total number of seat in concert hall how many tickets sold are balcony seats
Answers
Let b be the number of balcony seats. There are 450 lower seats; this makes the total number of seats 450+b. We know that there were 170 tickets sold, and that this is 1/5 the total number of seats; therefore our equation is
1/5(450+b)=170
Use the distributive property with the 1/5:
1/5*450 + 1/5*b = 170
90 + 1/5b = 170
Subtract 90 from both sides:
90 + 1/5b - 90 = 170 - 90
1/5b = 80
We can also write 1/5b as b/5:
b/5 = 80
Multiply both sides by 5:
(b/5) * 5 = 80 * 5
b = 400
You can add the number of seats and can take its one fifth and equate it to 170 to get the number of total seats.
There are total 400 tickets sold for balcony seats.
How to calculate the number of seats from tickets' data?Since the number of seats will be equal to that of tickets sold (assuming all seats will be covered), thus we can relate both the data.
How to find the total number of tickets sold for balcony seats?It is givn that 170 is 1/5th of the total seats.
Since total seats = 450 seats of the lower level + b seats of the balcony
Thus, we have:
[tex]170 = \dfrac{450 + b}{5}\\\\450 + b = 170 \times 5\\\\b = 850 - 450 = 400[/tex]
Thus, there are total 400 balcony seats and thus same number of tickets will be sold for balcony seats.
Thus, There are total 400 tickets sold for balcony seats.

The standard tip in a restaurant is 15% of the bill before tax. Many people in California find the tip by doubling the sales tax, which is 8.25%. By how many cents does this exceed the standard tip on a bill of 60% before tax?

The other strategy would be to find the difference on the percents and then multiply by $60. a. 8.25%x2=16.5%-15%. Difference of 1.5%. b. 0.015 x $60=$0.90.
Answer:

Step-by-step explanation:
The percent paid by many people in California is [tex]$16.50\%$, or $1.50\%$[/tex] more of the bill than the standard tip. Thus the total difference is [tex]$\$60\cdot 0.015 = \$0.90$[/tex], or [tex]$\boxed{90}$[/tex] cents.

Answer:
B lol
Step-by-step explanation:
don't ask me
The coach uses the mean to track player scores because it incorporates all scores, including unusually high or low ones, giving credit for exceptional performances. The median would only consider the middle score and discard extremes.
Explanation:The basketball coach uses the mean instead of the median to keep track of points scored per game for all her players because she wants to take unusually good or bad games into account (option B). The mean is calculated by adding up all the scores and dividing by the total number of games, so each game's score has a direct impact on the result. In contrast, the median only considers the middle score and discards extreme values, making it less sensitive to unusually high or low scores.
For instance, if a player scores 30 points in one game and then 10 points in each of the next nine games, their mean score would be (30 + 9*10)/10 = 13 points per game. In contrast, their median score would be 10 points per game because that's the middle value when all scores are listed in numerical order. Therefore, the choice to use the mean allows the coach to give credit for exceptional performances.

Answers
Answer:
Option A and D.
Step-by-step explanation:
In this question the given table is of two separate age groups to determine the number of hours teens spent on the internet each week.
From the table
average hours spent by teens between the age of 13-14 years old
= (12+8+7+8+9+6+7+7+9+10+15)/10 = 83/10 = 8.3 hours
average hours spent by teens between age of 15-16 years old
=(15+6+21+12+13+12+8+9+7+10)/10 = 113/10 = 11.3 hours
From these averages we can conclude
A) 15-16 year old spend a few hours more than 13-14 year old teens.
D. The amount that 15-16 year old teens spend on internet is more variable than the time spent by 13-14 years old.
Option A and D are the correct options.
