Find the derivation of the following functions with they corresponding variables
Answer:
d(f(t))/dt = –56/(t^8) – (5/6)/t^(7/6) + 12t^3 – 2t + (1/3)t^(2/3))
Step-by-step explanation:
To find the derivative of f(t), we have to find the derivative of each component of the function to make it easier.
d(8/(t^7))/dt = d(8xt^-7)/dt = –7 x 8 x t^-8 = –56t^-8 = -56/(t^8)
d(5/(t^(1/6)))/dt = –(1/6) x 5 x t^(-7/6) = –(5/6)/t^(7/6)
d(3t^4)/dt = 4 x 3 x t^3 = 12t^3
d(t²)/dt = 2t
d(t^⅓)/dt = ⅓t^(-2/3) = (1/3)t^(2/3))
d(12)/dt = 0.
Therefore,
d(f(t))/dt = –56/(t^8) – (5/6)/t^(7/6) + 12t^3 – 2t + (1/3)t^(2/3))

Write the exponential form of "(5)^-2 = 1/25" in logarithmic form *
The required logarithm form is -2log5
Given the exponential form of an equation expressed as;
[tex](5)^{-2} = 1/25[/tex]
For us to change the exponential form into logarithmic equation, first we need to identify the base, move it to the other side of the expression and then take the logarithm
Take the logarithm of both sides
[tex]= log(5)^{-2} \\=-2log5\\[/tex]
Hence the required logarithm form is -2log5

Marisa saved $3000 to take a bike trip from Florida to California. She estimated her expenses to be $40 per day. The cost of a ticket to fly back is $240. The inequality below can be used to find the maximum number of days (d) for which Marisa can pay the expenses on the bike trip.
40d + 240 ≤ 3000
Which inequality expresses the maximum number of days Marisa can pay the expenses for her bike trip?
d≤81
d≤75
d≤69
d≤40
Answer: d≤69
Step-by-step explanation:
You would plug in all the values for d into the inequality
40(81) + 240 ≤ 3000
40(81) + 240 = 3000
3240+240=3000
3480=3000 false
40(75) + 240 ≤ 3000
40(75) + 240 = 3000
3000+240=3000
3240=3000 false
40(69) + 240 ≤ 3000
40(69) + 240 = 3000
2760+240=3000
3000=3000 true
You don't need to try the last one because you already found this one!
The inequality expresses the maximum number of days Marisa can pay the expenses for her bike trip will be d ≤ 69.
What is inequality?Inequality is defined as the relation which makes a non-equal comparison between two given functions.
Marisa saved $3000 to take a bike trip from Florida to California.
She estimated her expenses to be $40 per day.
The cost of a ticket to fly back is $240.
The inequality below can be used to find the maximum number of days (d) for which Marisa can pay the expenses on the bike trip.
40d + 240 ≤ 3000
Substitute all the values for d into the inequality
For, d≤81
40(81) + 240 ≤ 3000
40(81) + 240 = 3000
3240+240=3000
3480=3000 false
For, d≤75
40(75) + 240 ≤ 3000
40(75) + 240 = 3000
3000+240=3000
3240=3000 false
For, d≤69
40(69) + 240 ≤ 3000
40(69) + 240 = 3000
2760+240=3000
=3000
therefore, LHS = RHS
Hence, d ≤ 69 is true.
