Answer:
A) ((x+1)^2)-3
B) f(x) = 2(x+1)^2 is vertically stretched upwards by a factor of 2. In addition to this, it’s minimum value remains on the x-axis, due to there being no vertical translation like in the equation on part A.
So: The equation in part A has no vertical stretch, and does have a vertical translation, however it retains the same horizontal translation.
Explanation:
You can see the transformations by looking at the vertex and at least 1 other point.
Since it is a parabola we can start by saying:
f(x) = x^2
We also see a vertical translation of 3 units down:
f(x) = (x^2)-3
Lastly, we see a horizontal translation of 1 unit to the left:
f(x) = ((x-1)^2)-3
Y = -2x+1 thats the answer its hecka easy
Answer:
216 cm²
Step-by-step explanation:
Applying,
V = lwh..................... Equation 1
Where V = volume of the cubiod, l = length of the base, width of the base, h = heigth of the cubiod.
From the question,
Since the base of the cubiod is squared,
Therefore,
w = l = 4 cm, V = 400 cm³
Substitute these values into equation 1
400 = 4×4×h
h = 400/(4×4)
h = 25 cm
A = lw+lh+wh.................. Equation 1
Where A = surface area of the cuboid.
Given: l = 4 cm. w = 4 cm, h = 25 cm
Substitute these values into equation 1
A = (4×4)+(4×25)+(4×25)
A = 16+100+100
A = 216 cm²
Answer: The result of the division is the number pi.
And the approximation of pi is: pi = 3.14
Step-by-step explanation:
The distance around a circle is called the perimeter of the circle.
The distance across a circle (This is a line that starts on one point of the circle, go through the center of the circle, and end in the next time it intersects the circle) is called the diameter of the circle.
The quotient between these two quantities is maybe one of the most famous numbers in the world, is the number pi, written as:
π = 3.14159265358979...
Is an irrational number, which means that the decimals keep going infinitely.
Then we can conclude that:
"The result of dividing the perimeter by the diameter, is equal to the number pi = π = 3.14159265358979..."
Because this is an irrational number and is actually impossible to write it, we usually use pi = 3.14 to aproximate it.
