The answer would be B, due to the fact that the shaded area is above the line.
Answer:
756
Step-by-step explanation:
In the last question the volume of the tank was 168 m³
so to find the cost multiply 168 and 4.5
it will cost 756
Answer:
17 hours
Step-by-step explanation:
so first since there are 520 pages we divide it by 124 pages we get 4.19
4.19x4 = 16.77
Rounded is 17
We want to choose 4 people and we have 6 people to choose from. This is a combination of 6, 4 by 4. Also called <em>six choose four</em>.
The following formula:

Is the combination of
objects choosen from a total of
. It's
choose
.
For our problem, we just need to compute the following:

Thus

Therefore the answer is 15 different combinations
solution:
Consider the differential equation,
7ty + (1+t2)1/2y1 = 0
Rewrite the DE as,
(1+t2)1/2dy = - 7ty
dy/y = -7t/√1+t2 dt
in y = -7(1+t2) + c
y = ce-7(1+t2)
given,
y(0) = 1 => ce-7 = -1 => c = e7
ᴪ (t,y) = y -ce ᴪ(0,1)(1+t2)
