Answer:
11:00 pm Wednesday
Step-by-step explanation:
Given
Current Time in San Francisco:
at 120 deg W
Required
Determine the current time at Miami at 75 deg W
First, we need to calculate the hours difference between San Franciso and Miami
Convert degrees to hours.
So:
The above is the time difference between San Francisco and Miami;
The time in Miami is then calculated as:
Hence, the time at Miami is: 11:00 pm Wednesday
Divide 6 by 3
3 goes into 6, 2 times so one apple costs $2
Answer:
a. -5
b.-5
c.-5
Step-by-step explanation:
In order to find the average rate of change of a function , we divide the change in the output value by the change in the input value.
Generally, the average rate of change (ARC) on an ecuatios between two points (x1,f(x1)) and (x2,f(x2)) is
- ARC = [f(x2)-f(x1)]/ (x2-x1)
<em>In case a)</em>
f(-1)= -5*(-1)-8=5-8= -3 f(3)= -5*3-8= -23
Then ARC= (-23-(-3))/(3-(-1))=-20/4=-5
<em>In case b)</em>
f(a)= (-5a-8)
f(b)= (-5b-8)
Then ARC= [(-5b-8)-(-5a-8)]/(b-a)= (-5b+5a)/(b-a)= -5(b-a)/(b-a)= -5
<em>In case c)</em>
f(x)= -5x-8
f(x+h)= -5(x+h)-8= -5x-5h-8
then ARC= [(-5x-5h-8)-(-5x-8)]/(x+h-x) =-5h/h= -5
Answer:
Step-by-step explanation:
|4r−12| = -(4r-12) when 4r-12< 0
4r< 12 so r<3
