Answer:
31.925 ft
Step-by-step explanation:
A diagram is needed to visualize Dylan's movement to Alex see below
thus (-22.4)² + y² = 26²
y² = 26² - (22.4)² = 174.24
y = -√174.2 = - 13.2 ft note due south
closest point at intersection
3/11* ( x- 26) = -11/3 x * + 26
3/11 x - 78/11 = -11/3x + 26
3/11 x +11/3x = 26 + 78/11
130/33 x = 364/11
x = 364/11 * 33/130 = 8.4
then y = 3/11 * (x -26)
x = 8.4 substitute, gives y = 3/11 * (8.4 -26) = -4.8
distance from (8.4 , -4.8) to (0 , 26)
√[(0 -8.4)² + ( 26-(-4.8))² ] = √[( -8.4)² + ( 30.8)² ] = 31.925 ft
Answer:
I think that c is the correct answer
Answer:
f(2) = $180.22
f'(2) = $130.00/week
f'(2)/f(2) = 72.13%
Two weeks after the DVD was released, the revenue from sales is $180.22 and is increasing at a rate of $130 per week, or 72.13% per week.
Step-by-step explanation:
The revenue from sales, in dollars, as a function of time, in weeks, is given by:
After two weeks (t=2), the revenue from sales is:
The rate of change, which is given by the derivate of the revenue function, at t = 2 weeks is:
The relative rate of change is:
Therefore, Two weeks after the DVD was released, the revenue from sales is $180.22 and is increasing at a rate of $130 per week, or 72.13% per week.
Answer:
105 frames
Step-by-step explanation:
Given that 25 frames are played per second
25 frames= 1 sec
The video already played 3 and 2/5 seconds before the player started to count 0
Write 3 and 2/5 seconds as an improper fraction
=(5*3)+2 / 5 = 17/5 seconds
Multiply by 25 frames
17/5 *25 =85 frames
So according to the video counter,after 17/5 seconds,it should count 85 frames.However,at 0 seconds,it indicated a count of 190 frames.Thus,to get the number of frames that were already in count you subtract 85 frames from the 190 frames.
190-85=105 frames.
