Hello from MrBillDoesMath!
Answer:
The last choice x^2 - x^(1/2) + 2
Discussion:
The last choice x^2 - x^(1/2) + 2 is NOT a polynomial because of the sqrt(x) term
Thank you,
MrB
Take the dot product, if the dot product is zero, they are orthogonal
<span>the dot product here is 15(-5) + 45(12) so the vectors are not orthogonal </span>
<span>to see if they are parallel, take the dot product again, using the definition </span>
<span>u dot v = mag u x mag v cos (theta) where mag is the magnitude of the vector and theta is the angle between them </span>
<span>we know from above that u dot v = 465 </span>
<span>mag u = sqrt[15^2+45^2]=47.43 </span>
<span>mag v = sqrt[5^2+12^2]=13 </span>
<span>so we know: </span>
<span>cos(theta) = 465/(47.43x13) = 0.75 </span>
<span>
so theta = 41 deg</span>
I would add, the weight of the backpack and the weight of the school books which is 28.36.
So Rico's backpack altogether weighs 28.36.
I'm pretty sure.
Since 1 kilogram equals 1,000 grams 5 potatoes equals 1,000 grams. 1,000 divided by 5 is 200. This means 1 potato has a mass of 200 grams 1,200 divided by 8 is 150. that means a pear has a mass of 150 grams. Since 200 grams is bigger then 150 grams, that means the potato has greater mass>

Answer:
Step-by-step explanation:
Actually, you can't do that because 7 is never equal to 6.
"7 is greater than 6" is ok: 7 > 6
but
7 ≠ 6
Note: "7 is greater than or equal to 6 into algebraic equation" is not possible because you cannot change an inequality into an equation.
