Answer:
Reflect in the line y = -1 then translate 10 units to the right.
Step-by-step explanation:
Lets see what happens to the point A:
Its starts at (-8, 8) and ends up at A' (2, -10).
If we reflect in the x axis A goes to (-8,-8).
Now translate 10 units to the right moves it to (2, -8.)
And a second translation of 2 units down takes it to (2, -10).
Oh, another way would be to reflect in the line y = -1 then translate 10 units to the right. That's only 2 transformations.
The first thing we must do for this case is find the volume of the sphere.
The volume is given by:
V = (4/3) * (pi) * (r ^ 3)
Where,
A: Radius of the sphere
Substituting values:
V = (4/3) * (3.14) * (4 ^ 3)
V = 267.95 in ^ 3
Then, the weight of the sphere is:
W = (267.95) * (0.75)
W = 200.9625 pounds
Round to the nearest pound:
W = 201 pounds
Answer:
The weight of the sphere is:
W = 201 pounds
If two angles are complementary, the sum of their measures is 90 degrees. Call one of the angles x. This means that its complement is 90 - x degrees. But the difference in their measures is 12 degrees.
This procedure is known as estimating or rounding, where one compares the digit to the right is the number and sees whether or not is found within a given range, greater than 5 and can be used to increase the number in question, by a value of 1.
