Answer:
Option B: |x - 27.6| = 5.3
Step-by-step explanation:
We are told that the average time for athletes on the Central High School track team to run 200 meters is 27.6 seconds.
We are also told that the slowest and fastest recorded times varied from the average by 5.3 seconds.
This means that the slowest time varied by 5.3 seconds more than the average while the fastest time varied by 5.3 seconds less than the average.
If x is to represent the slowest or fastest time, the absolute value equation can be written as;
|x - 27.6| = 5.3
Using the given table of transforms,
(where Y(s) is the Laplace transform of y(x))
Solve for Y(s) :
Decompose the right side into partial fractions:
Solve for the coefficients.
Then
Take the inverse transform and solve for y(x) :
Using the frequency-shifting property,
So, the particular solution to the ODE is
this might be wrong but i would say B. hope this helps :) sorry if wrong
Answer:
9 3/4
Step-by-step explanation:
3 1/4+6 1/2=
9+ 3/4
the answer is 9 3/4
Answer:
85 and -31
step-by-step:
x + y = 54
x - y = 116
solve for x in first equation
x = 54 - y
sub into second equation
54 - y - y = 116
54 - 2y = 116
-2y = 62
y = -31
sub in x equation
x = 54 - (-31)
x = 85
