The director of the department of transportation wants to know if the pile of salt for use on the ice roads is too tall to cover with their tarpaulin. the salt is in a pile that is shaped like a right circular cone. the formula for the volume of a right circular cone is v= 1/3 (pie r squared h). the radius, r, of the circular base of the pile is 2.5 meters. the volume of the cone, v, is 40 cubic meters. if the tarpaulin can cover a cone up to 7 meters tall, can it cover the pile?

Yes it can

Step-by-step explanation:

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.
