Answer:$18
Step-by-step explanation:4 * 4 = $16. One pair of pants = $13. 16 + 13 = $29. 47 - 29 = $18
Answer:
14 and 22
Step-by-step explanation:
If x is the first number, then 36-x is the second. We are told that ...
2x -(36-x) = 6 . . . . twice the first less the second is 6
3x = 42 . . . . . . . . . add 36
x = 14
(36 -x) = 22
The numbers are 14 and 22.
Answer:
f(x)= x^3
Step-by-step explanation:
Integration will be ln | ( x /9 ) + (
) | + c .
Given ∫ 1 dx / (
- 81 )
Put ,
x = 9 secθ
dx = 9 secθ tanθ dθ
and
= 9 tanθ
Substituting values in ∫ 1 dx / (
- 81 ) ,
∫ (9 secθ tanθ ) dθ / ( 9 tanθ )
∫ secθ dθ = ln | secθ + tanθ | + c
= ln | ( x /9 ) + (
/ 9 ) | + c
= ln | ( x /9 ) + (
) | + c
Hence , the integration will be ln | ( x /9 ) + (
) | + c .
