Answer:
19,600 Nm
Step-by-step explanation:
WD = mgh
= 40 × 9.8 × 50
= 19600 Nm
You just divide 3/8= 0.375
Answer:
variation constant = k = 8
equation of variation : y = 8x
Step-by-step explanation:
Any relationship of variation can be written as y = kx
where k is the variation constant.
_______________________________________
Let the equationof relation between y and x be y =kx here as well
given
y = 16 when x = 2
substituting this value in the equation y = kx
16 = k*2
=> k = 16/2 = 8
Thus,
variation constant = k = 8
equation of variation : y = 8x
Answer:
-4c + 5d
Step-by-step explanation:
3 - 7 = -4, so c is equal to -4.
Since there is only one value for d, d stays the same as 5d.
(x^2-5)(3x-1)
Here's how I got this answer:
I found the GCF for each part of the polynomial.
3x^3 and -15x both contain 3x, and -x^2 and 5 share -1.
I then can divide the polynomial by 3x-1, and I get x^2-5
(Okay, that's not what I really did, but I can solve these on sight and don't remember the proper way to do it.)
