Help pls The function y = 3.25 + 2.5(x − 1) can be used to determine the total cost (y) of a taxi ride of x miles. What is the rate of change of the cost in dollars with respect to the number of miles? A) $0.75 per mile
B) $2.50 per mile
C) $3.25 per mile
D) $5.75 per mile

c 1 hour

step-by-step explanation:

m = 2e

m = 2 so 2 = 2e

1 = e

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
