Answer:

Width 10y^6 units

Length 7y^2+3 units

Step-by-step explanation:

The rectangle has an area of 70y^8+30y^6.

The width of the rectangle is equal to the greatest common monomial factor of 70y^8 and 30y^6. Find this monomial factor:

70y^8=2\cdot 5\cdot 7\cdot y^8\\ \\30y^6=2\cdot 3\cdot 5\cdot y^6\\ \\GCF(70y^8,30y^6)=2\cdot 5\cdot y^6=10y^6

Hence, the width of the rectangle is 10y^6 units.

The area of the rectangle can be rewritten as

10y^6(7y^2+3).

The area of the rectangle is the product of its width by its length, then the length of the rectangle is 7y^2+3 units.

I can Multiply a 11x6 matric by a 6x7 matrix. The resulting matrix will be ??? Can somebody help me
Bumek [7]

Answer:

The resulting matrix will be 11 * 7

Step-by-step explanation:

Given

Matrices 11 * 6 multiplied by 6 * 7

Required

The dimension of the resulting matrix

When a matrix a * b is multiplies by a matrix b * c, the resulting matrix will be: a * c

In this case:

a * b = > 11 * 6

b * c => 6 * 7

So, the resulting matrix will be:

a * c => 11 * 7

Answer:

The answer is option A

Step-by-step explanation:

Reflection in the y axis is

(x , y) → ( - x , y)

The coordinates of A are ( 2, -5)

When it's reflected in the y axis it becomes

( - 2 , - 5)

Which equations can be used to solve for acceleration? Select four options.
sweet [91]

Equations for the acceleration: a=\frac{v-u}{t}, v=u+at

Step-by-step explanation:

The acceleration of a body is the rate of change in velocity of the body; it is given by

a=\frac{v-u}{t}

where

v is the final velocity

u is the initial velocity

t is the time taken  for the velocity to change from u to v

The equation can be also written as

v=u+at

Therefore, these two equations can be used to find the acceleration.
