Being that the triangle has a center of dilation at (0,0) you must contract the points towards (0,0). The scale factor is 1/3 so you must divide the difference in location of the points on the X and Y axis by a scale of 1/3.
1/3 of 9 = 3 , y = 3
1/3 of -6 = -2 , x = -2
by changing these points a new triangle will be formed
Hello,
Cube X: volume=x
Cube Y: volume=8x
Y has a volume 2^3 times of the X cube
So,
the side of the Y cube is twice the volume of the X cube.
The side of the X cube is half of the cube Y
Side of X cube=y/2
23 x 76 is 1748
I hope this helps :)
Wow that looks so cool!, is that toothless?
Answer : The time taken by the element to decay to 2 grams is, 75.2 minutes
Step-by-step explanation:
Half-life = 13 min
First we have to calculate the rate constant, we use the formula :



Now we have to calculate the time passed.
Expression for rate law for first order kinetics is given by:

where,
k = rate constant = 
t = time passed by the sample = ?
a = initial amount of the reactant = 110 g
a - x = amount left after decay process = 2 g
Now put all the given values in above equation, we get


Therefore, the time taken by the element to decay to 2 grams is, 75.2 minutes
