Help! What is |-3|+|3| ?

kvv77 [185]

$|a|= \left\{\begin{array}{ccc}a&for\ a\geq0\\-a&for\ a \ \textless \ 0\end{array}\right\\\\Examples:\\|2|=2\ because\ 2\geq0\\|0|=0\ because\ 0\geq0\\|-5|=-(-5)=5\ because\ -5 \ \textless \ 0\\|-100|=-100\ because\ -100 \ \textless \ 0$

|-3| + |3| = 3 + 3 = 6

What is the distance between two points on the globe 30° north and 50° south

wlad13 [49]

Answer:

The distance between two points on the globe 30° north and 50° south at the equator is the same as latitude, roughly 69 miles. At 45 degrees north or south, the distance between is about 49 miles (79 km). The distance between longitudes reaches zero at the poles as the lines of meridian converge at that point.

Step-by-step explanation:

Sorry If it is wrong.

Which expressions are completely factored? Select each correct answer. 32y10−24=8(4y10−3) 18y3−6y=3y(6y2−2) 16y5+12y3=4y3(4y2+3)

laila [671]

Answer:

Option A and Option C

Step-by-step explanation:

Option A: $32y^{10}-24 = 8(4y^{10}-3)$ This is completely factored as 8 is the Highest Common Monomial factor

Option B: $18y^{3}-6y = 3y(6y^{2}-2)$ This is not completely factored as 2 is still a common factor of 6y2 and -2.

Option C: $16y^{5}+12y^{3}=4y^{3}(4y^{2}+3)$ This is completely factored as 4y2 is the Highest Common Monomial factor

Option D: $20y^{7}+10y^{2} = 5y(4y^{6}+2y)$ This is not completely factored as 2y is still a common factor of 4y6 and 2y.

So the options that are completely factored are Option A and Option C
