Answer:
Answer = x5+5x4+x3
Step-by-step explanation:
x3(x2+5x+1)
=(x3)(x2+5x+1)
=(x3)(x2)+(x3)(5x)+(x3)(1)
=x5+5x4+x3
Answer = x5+5x4+x3
X ⇒ ln (2)
e^3 x - 8/e^2 x - 4
So you have a right angle triangle. You need to use trig for this, as you have two values you can figure out a third.
You know that you have
90 deg. angle
19 deg. angle
Therefor you have 71 deg. angle
sin19 = x/15
15sin19 = x
x = 2.2
Now do Pythagoras c^2-b^2=a^2
a = 14.8
So the sides are 2.2 and 14.8 units long. (If these numbers are wrong tell me and I'll edit answer)
75% because a third quartile is 3/4 which is 75% which if you break each fourth down it would be 25% so then you multiply 25%x3 to get 75%
