Answer:
Step-by-step explanation:
N is 3 bc #of terms minus 1
Exponents go from 3>2>x>none
Can be factored using binomial theorem
Hi there!

Work out the parenthesis.

Combine like terms.

Subtract 9 from both sides.

Subtract 4x from both sides

Divide both sides by -9
To answer your question, this could be the possible answer and i hope you understand and interpret it correctly:
<span>[Integrate [0, 1/2] xcos(pi*x
let u=x so that du=dx
and v=intgral cos (xpi)dx
v=(1/pi)sin(pi*x)
integration by parts
uv-itgral[0,1/2]vdu just plug ins
(1/pi)sinpi*x]-(1/pi)itgrlsin(pi*x)dx from 0 to 1/2
(1/pi)x sinpi*x - (1/pi)[-(1/pi) cos pi*x] from 0 to 1/2
=(1/2pi)+(1/pi^2)[cos pi*x/2-cos 0]
=1/2pi - 1/2pi^2
=(pi-2)/2pi^2 ans</span>
Answer:
The tree diagram is shown in the tree diagram is shown.
If the probability to hit is 0.7, then the probability to miss is 0.3.
P(hit, hit) = 0.7*0.7 = 0.49
P(hit, miss) = 0.7*0.3 = 0.21
P(miss, hit) = 0.3*0.7 = 0.21
P(miss, miss) = 0.3*0.3 = 0.09
Answer:
The answer is: b5y + 9 = 16
