The error in rounding a number is half of the unit of measure. The number was rounded to the nearest 0.1 unit so the error is half of 0.1 which is 12⋅0.1=0.05

​
⋅0.1=0.05. Since 3.7+0.05=3.75
3.7+0.05=3.75 and 3.7−0.05=3.65
3.7−0.05=3.65, then the error interval is \boxed{3.65\le x<3.75}.

Moira said, "If a right triangle has one side with a length of 3 units and one side with a length
Dima020 [189]

If the two sides with length 3 and 4 are the two legs, then the missing side, i.e. the hypotenuse, is indeed 5.

But it could also be the case that 4 is the hypotenuse and 3 is one of the legs. In this case, the missing side is the other leg, so we calculate it using

\sqrt{4^2-3^2}=\sqrt{16-9}=\sqrt{7}

So, a right triangle with legs \sqrt{7} and 3 has an hypotenuse of 4.

masha68 [24]

Answer:

21+12i i hope this will help you

Step-by-step explanation:

(3-4i)(1+5i)-(2-i)

=[3(1+5i)-4i(1+5i)]-(2-i)

=[3+15i-4i-20i²]-(2-i)

=(3+11i-20i²)-(2-i)

opening brackeys

=3+11i-20i²-2+i

=3+11i+1i-20i²-2

as we know that i²=-1

=3-20(-1)-2+12i

=3+20-2+12i

=21+12i
