When a shape is rotated, it must be rotated around a point.
<em>See attachment for the image of each rotation.</em>
To do this, the top coordinates of the X shape will be transformed using the appropriate rotation rule; the same rule will then be applied to the other parts of the X shape.
The top coordinates of the X shape are:




For 90 degrees counterclockwise rotation, the rule is:

So, we have:




For 180 degrees rotation, the rule is:

So, we have:




For 270 degrees counter rotation, the rule is:

So, we have:




See attachment for the image of each rotation

Pls see answer below.
Step-by-step explanation:
In this case, our slope is -8. This means that every hour, the storm is getting closer to the town by 8 miles per hour.
Our y-intercept is 200, which means that its' initial position is 200 miles away from the town.
Hope this helped.
Answer:
A) y=(x-8)^2-5
B)y=10(x+6)^2
C) y=-0.6(x+7)^2-2

Answer:
40.5 g
Step-by-step explanation:
Find how much salt is in 450 g of a 9% salt solution.
Note that
450 g - 100%,
x g - 9%,
then

If you evaporated all water from this solution, then you would get 40.5 g of salt.
Answer:
k = -2
Step-by-step explanation:
x -1 0 2 5
f(x) 2 0 -4 -10
ƒ(x) = kx
Substitute a pair of values for x and ƒ(x)
-10 = k×5
Divide each side by 5
k = -2
The constant of variation k = -2.
