MAVERICK [17]

Answer:

2x^2y[x^{2}y^{2}-6xy-4]

Step-by-step explanation:

we have

2x^{4}y^{3}-12x^3y^2-8x^2y

Factor 2x^2y

so

2x^2y[x^{2}y^{2}-6xy-4]

Given u = −8i − 3j and v = −12i − 7j, what is projvu?
8090 [49]

Answer:

  (b)  -7.275i -4.244j

Step-by-step explanation:

The projection of vector u onto vector v is the product of the unit vector v, the magnitude of vector u, and the cosine of the angle between them.

__

The dot product gives the product of the magnitudes of the two vectors and the cosine of the angle between them. To find the projection, we must divide the dot product by the magnitude of v and multiply by the unit vector in the direction of v.

  proj(u,v)=(\vec{u}\cdot\vec{v})\cdot\dfrac{\vec{v}}{|\vec{v}|^2}=\dfrac{((-8)(-12)+(-3)(-7))(-12\vec{i}-7\vec{j})}{(-12)^2+(-7)^2}\\\\=\dfrac{-(96+21)(12\vec{i}+7\vec{j})}{144+49}=-\dfrac{117}{193}(12\vec{i}+7\vec{j})\approx\boxed{-7.275\vec{i}-4.244\vec{j}}

Answer:

\frac{7}{22}, the total sum of the money is    

Step-by-step explanation:

1- \frac{5}{11}= \frac{6}{11}

\frac{6}{11}*\frac{7}{12}= \frac{7}{22}

x* \frac{7}{22}= 4500

4500/\frac{7}{22}= about 14142.85

this is what I got out.
