Answer:
18x+63
Step-by-step explanation:
First you've to simplfy it, multiply the first bracket by 5 and the second by 4.
= (5)(2x)+(5)(7) + (4)(2x)+(4)(7)
= 10x+35+8x+28
Combine Like Terms:
= 10x+35+8x+28
= (10x+8x)+(35+28)
= 18x+63

Answer:
credits to the two revenue accounts
Explanation:
The journal entry above is focusing on <u>"two revenue accounts"</u> and these are "Fees Earned" and "Rent Revenue."
Remember that "Fees Earned" is part of the revenue section in the<em> Income Statement.</em> It is the amount of money earned for services provided such as <em>auditing fees</em> or <em>consulting fees.</em>
An increase in revenue is being credited when it comes to<em> journal entries.</em> So, this means that "credits to the two revenue accounts" have to be made.
So, this explains the answer.
<u>Answer</u>:
25) If f(x) = sin ([1/3] x) , find f(π/2).
Substitute with x = π/2
f(π/2) = sin ([1/3] *[π/2]) = sin (π/6) = 1/2
======================================
26) If f(x) = cos (2x) , find f(3π/4).
Substitute with x = 3π/4
f(3π/4) = cos ( 2 * 3π/4) = cos ( 3π/2) = zero.
======================================
27) If f(x) = sin (2x) + cos (3x) , find f(π/4)
Substitute with x = π/4
f(π/4) = sin ( 2 * π/4) + cos ( 3 * π/4) =
= sin ( π/2) + cos ( 3π/4)
= 1 - 1/(√2)
= 0.293
======================================
28) f(x) = tan (5x) - sin (2x) , find f(π/6).
Substitute with x = π/6
So, f(π/6) = tan (5 * π/6) - sin ( 2 * π/6)
= tan (5π/6) - sin (π/3)
= -1/(√3) - (√3)/2
= -1.443
