Answer:
14 = x
Step-by-step explanation:
-2 on both sides you get 7 = x/2, multiply both sides by 2 and you get 14 = x
V= s^3
a=486/6=81
s=sqrt(81)=9
v=9^3=729
the volume of the cube is 729cm^3
In short, let x be the height of the Light House
2.5/36 = 1.5/X
===> X= (36 x 1.5)/2.5 = 21.6 meters
Wait let me know that the .12 means in the first question and i will fix the answer
int (x)(cosx) dx
u=x ----> take derivative du=dx
dv=cosx -----> take integral v=sinx
now use integration by parts
u v - int (v)du
x sinx - int (sinx) (1) dx=
x sinx - (-cos(x)) + c =
answer is = x sinx + cosx + c
Actually they want you to simplify the problem.
The problems answer is:
30 goes into 15; 2 times.
Final Answer: 2
