You would use v=lwh (volume= length x width x height)
You first round 289 and get 290 then multiply it by 7
The formula is a permutation in which n represents the sample points in the set, while r represents the number of sample points in each permutation.
Answer:
D. 
Step-by-step explanation:
The point-slope form of a line is given by:

The line given to us has equation;
.
The slope of this line is -4. The of the line perpendicular to this line is the negative reciprocal of the slope of the given line.
Our slope of interest is therefore; 
Since the point goes through (-2,7), we have
.
We plug in the slope and the point into the point-slope formula to obain;

The required equation is:

Answer:
686.7 N
Step-by-step explanation:
mass the person is 70 kg , which is constant for the entire universe.Although weight of the person is depends upon the gravity of the planet on which he resides
W= mg
m= mass W= wight and g= Acceleration due to gravity of the planet which 9.81 m/sec^2 on earth.
therefore weight W = 70×9.81 = 686.7 N
Hence the weight of the father will be 686.7 N
