Karlena is on an old cell phone plan. the cost of a call depends on the number of minutes the phone call lasts. she can use the expression $0.10m+3.500.10m+3.50 to find the cost of a call. if m is the number of minutes, which of the following best describes $3.50?

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

i belive those are the ones that are under 90 degreese.

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.

answer is c
