Answer:

k = 2

Step-by-step explanation:

Based on the right triangle altitude theorem, thus:

4 = √(k*8)

Square both sides

4² = k*8

16 = 8k

Divide both sides by 8

16/8 = 8k/8

2 = k

k = 2

Is y-4=2(x-2) and 4x-2y=5 perpendicular
djyliett [7]

Answer:

Therefore,

Slopes are Equal, Hence the Lines are not Perpendicular.

Step-by-step explanation:

Given:

y-4=2(x-2)=2x=-4\\\\y=2x .......Equation ( 1 )

4x-2y=5\\2y=4x-5\\\\y=2x-\dfrac{5}{2}  .......Equation ( 2 )

Comparing with,  

y=mx+c ......General Slope point form  

Where m =slope  

We get  

Slope = m1 = 2   For Equation ( 1 )

Slope = m2 = 2   For Equation ( 2 )

Hence,

m1=m2[=2

Therefore, Slopes are Equal Hence the Lines are Parallel not Perpendicular.

For Perpendicular we require

m1\times m2=-1

Therefore,

Slopes are Equal, Hence the Lines are not Perpendicular.

Factor out the GCF 45c^6+20c^4
tatiyna

Answer:

5c^4( 9c^2 + 4).

Step-by-step explanation:

The GCF of 45 and 20 is 5 and the GCF of c^6 and c^4 = c^4.

So the GCF is 5c^4 and the factors are:

5c^4( 9c^2 + 4)
