During a scuba dive, Lainey descended to a point 23 feet below the ocean surface. She continued her descent at a rate of 20 feet per minute. Write an inequality you could solve to find the number of minutes she can continue to descend if she does not want to reach a point more than 123 feet below the ocean surface. Use the variable t for time. What is the inequality??

Answer

-20-20x>-100

Step-by-step explanation:

Let represent the number of minutes. Since she is descending 20 feet per

minute, then —201 represents her change in altitude. It is nega.ti'.v since

descending means her altitude is decreasing.

Since she started at 20 feet below the ocean surface, she started at —20 feet.

Its nogati'.•v since au altitude below the ocean surface must be represented

by a negatiw• number.

Her ending position is the sum of how far she has descended and her initial

position so her ending position is —20 + (—201) —

-20 - 201.

She doesn't want to travel more than 100 feet below the ocean surface so she

needs to be higher than —100 feet. Tho inequality is then —20— 20.T —100.

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
