Answer:
120
Step-by-step explanation:
It is the only constant in the equation, 120.
_____
The proportionality is to the inverse of the square of d.
Do 35/1 and then make 1 1/2 into an improper fraction (which is 3/2) and you do 35/1 * 3/2 you should get 105/2 and then make it into an mixed fraction.
Answer:
26) x = 4
Step-by-step explanation:
26)
20x + 5 + 24x - 1 = 180
20x + 24x = 180 + 1 - 5
44x = 176
x = 176/44
x = 4
Gradient of AB = y1-y2/x1-x2
= -3-0/1-1
= -3/0
gradient of AB = gradient of CD (as AB is parallel to CD)
therefore D = 3+y3/0+x3
= -3+2/0+4
= -1/4
since y/x of D = -1/4,
the coordinates of D is (4,-1) [option B]
