Answer:
Because the product is always non-termination,non-repeating decimal.
Step-by-step explanation:
If we have 
is irrational; 
is rational such that 
, then 
is irrational.
A way to represent this is:
Note that we have a contradiction, because is not a rational number, as I stated in the beginning. Therefore, ab is irrational.
A polygon has coordinates A(-7, 8), B(-4, 6), C(-4, 3), D(-8, 3), and E(-9, 6). What are the coordinates of its image, polygon A

The correct answer is third set of points: <span>A′(6, 10), B′(4, 7), C′(1, 7), D′(1, 11), E′(4, 12)
</span><span>
We can figure out this answer, just by looking at the first point A. If we rotate it 270 degree counterclockwise, if will go from the second quadrant to the first quadrant.
The new point will be (8, 7). If we move left 2 and up 3, we will be at the point (6, 10). Only the second choice matches this.</span>
Answer:
Slope is 1/2
Step-by-step explanation:
Using the slope formula y₂-y₁/x₂-x₁
(x₁,y₁) and (x₂,y₂) → (1,2) and (3,3)
So...
3-2=1
3-1=2
1/2
Answer:
144=12², so 144^3/2=(12²)^(3/2)=12³=1728.

To find the gradient of the tangent, we must first differentiate the function.
The gradient at x = 0 is given by evaluating f'(0).
The derivative of the function at this point is negative, which tells us <em>the function is decreasing at that point</em>.
The tangent to the line is a straight line, so we will have a linear equation of the form y = mx + c. We know the gradient, m, is equal to -1, so
Now we need to substitute a point on the tangent into this equation to find c. We know a point when x = 0 lies on here. To find the y-coordinate of this point we need to evaluate f(0).
So the point (0, -1) lies on the tangent. Substituting into the tangent equation:
