Answer: DF = 25

Explanation:

Look closely at the picture

We see that BC = FD

But AC = 50

But B is the midpoint of AC which mean BC = 25

Therefore, BC = DF = 25

Answer:

- \frac{3}{5}

Step-by-step explanation:

slope-intercept form: y = mx + b

y = (x , y)

m = slope = -\frac{3}{5}

x = (x , y)

b = y-intercept = - \frac{7}{9}

With this given information, your slope will be -\frac{3}{5}

For what values of b are the given vectors orthogonal? <br><br> (−30, b, 5), (b, b2, b)
mart [117]

Given :

Two vectors :

v_1=-30i+bj+5k\\\\v_2=bi+2bj+bk\\\\

To Find :

The value of b for which the vectors are orthogonal .

Solution :

We know , two vectors are orthogonal when the are perpendicular to each other .

So , their dot product will be zero .

So ,

-30b+2b^2+5b=0\\\\2b^2-25b=0\\\\b(2b-25)=0

Therefore , for b =0 and b=\dfrac{25}{2} the vectors are orthogonal .

Hence , this is the required solution .
