Which represents the base of the cone

the first option

Step-by-step explanation:

the 6 represents the diameter of the base

the 4 represents the height of the cone

if it needs a radius to solve the problem, divide the diameter by 2 (aka half of the diameter)

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
