Answer:
lets consider two end points are the marked points ,
Then ,
(1,5)=x1,y1
(-1,-3)=x2,y2
line passes through point(1,0)=x3,y3
slope of line ,m = (y2-y1)/(x2-x1)
= (-3-5)/(-1-1)
=4
Eqn of line is:
y-y3=m(x-x3)
y-0 = 4(x-1)
y=4x-4
4x-y=4 is reqyuired eqn..
Step-by-step explanation:
Problem may arise due to calculation but plz check it ...
Answer:
m is the slope and b is the y-intercept. Therefore, for the equation y=x+5 , the slope is 1 , and the y-intercept is 5
Step-by-step explanation:
A unit vector in the direction of a would be the vector a multiplied by a factor such that the length of vector a is unity.
The magnitude of a is given by:
|a|
=sqrt(4^2+3^2+2^2) [ I got lazy instead of writing (-4)^2+(-3)^2+2^2]
=sqrt(29).
So the univector is a/sqrt(29), or (-4/sqrt(29),-3/sqrt(29), 2/sqrt(29), or simply (-4,-3,2)/sqrt(29).
D, the number inside of the absolute lines are just the exact same number in there but just positive. If the number was positive the number would still be the number:
|100| = 100
|-100| = 100
Answer:
1,235,520
Step-by-step explanation:
13P6 = 13!/(13-6)! = 13·12·11·10·9·8 = 1,235,520
__
There are 13 ways to choose the first object, 12 ways to choose the second, 11 ways to choose the third, and so on. The 6th object can be chosen 8 ways.
The total number of permutations is the product of all these ways:
13·12·11·10·9·8 = 1,235,520
