A leatherback sea turtles was swimming at 850 below sea level. He went 165 meters and then descendes 165 meters. Draw a number line to show the change in position of the sea turtles from depth it was swimming. What integer represents the sea turtles change in position?
Answer:
The answer is below
Step-by-step explanation:
a) Let negative means the turtle position when descending and positive for going up. Therefore since the turtle was 850 meters below see level, it was at -850. It then moves 165 meters up, hence its new position is -685 meters (-850 + 165). Lastly it moves down 165 meters, hence its new position is -850 meters (-685 - 165)
b) The change in position is the sum of the movements = +165 - 165 = 0 meters.

Raul works at a movie theatre. The function f(x) represents the amount of money Raul earns per ticket, where x is the number of tickets he sells. The function g(x) represents the number of tickets Raul sells per hour, where x is the number of hours he works. Show all work to find f(g(x)), and explain what f(g(x)) represents.
f(x) = 2x2 + 16
g of x equals the square root of the quantity 5 x cubed
Answer:
Step-by-step explanation:
Given f(x) = 2x²+16
g(x) = √5x³
First is to get the composite function f(g(x))
f(g(x)) = f(√5x³)
To get f(√5x³), we will replace x in f(x) with √5x³ as shown:
f(√5x³) = 2(√5x³)²+16
f(√5x³) = 2(5x³)+16
f(√5x³) = 10x³+16
Hence f(g(x)) = 10x³+16
f(g(x)) will be the function of amount earned by Raul for the total number hour he works

The price of fancy coffee has increased 9% each year for the last several years.
If the current cost $8 per pound, what did a pound cost two years ago
Answer:
$6.56
Step-by-step explanation:
First, take 8 and divide it by 100. Then you have 0.08. multiply that by 9. You get 0.72, that is how much the price increases every year. multiply that by 2, and you get 1.44. subtract 1.44 from 8, and you are left with $6.56, the price it was two years ago.
find the zero for f (x)=80-10x
Answer: =80/11
Step-by-step explanation:x=80-10x
We move all terms to the left:
x-(80-10x)=0
We add all the numbers together, and all the variables
x-(-10x+80)=0
We get rid of parentheses
x+10x-80=0
We add all the numbers together, and all the variables
11x-80=0
We move all terms containing x to the left, all other terms to the right
11x=80
x=80/11
x=7+3/11

A company rents out 17 food booths and 21 game booths at the county fair. The fee for a food booth is $75 plus $10 per day. The fee for a game booth is $95 plus $4 per day. The fair lasts for d days, and all the booths are rented for the entire time. Enter a simplified expression for the amount, in dollars, that the company is paid.
Answer:
Food booth= (75+10d)17
Game booth= (95+4d)21
Step-by-step explanation:
GAME BOOTH
$95 initial fee plus $4 per d amount of days
f(x)=95+4d
Multiply the expression by 21 because you have 21 game booths
FOOD BOOTH
$75 initial fee plus $10 per d amount of days
f(z)=75+10d)
multiply this expression by 17 because their are 17 food booths

2.5/6 = h/9 h=? What does this mean
Answer:
h = 3.75
Step-by-step explanation:
Step 1: Write equation
2.5/6 = h/9
Step 2: Solve for h
Cross multiply: 22.5 = 6hDivide both sides by 6: 3.75 = hRewrite: h = 3.75Step 3: Check
Plug in h to verify it's a solution.
2.5/6 = 3.75/9
0.416667 = 0.416667
Answer:
h = 3.75
Step-by-step explanation:
Given
[tex]\frac{2.5}{6}[/tex] = [tex]\frac{h}{9}[/tex] ( to solve for h, cross- multiply )
6h = 22.5 ( divide both sides by 6 )
h = 3.75
