Answer:
Ellipse C
Circle E
Sphere B
Great Circle D
Triangle A
Step-by-step explanation:
Cross sections are slices through a 3d figure to create a 2d shape. A cone creates a circle and triangle. A sphere creates a great circle. A cylinder creates an ellipse. Rotating a semi circle around an axis creates a sphere.
This is a square with area 36 in^2
So dimensions are 6 * 6 ins and perimeter = 24 ins.
Answer:
That is has root -12 meaning if you replace x with -12 you get 0.
X² - 7x + 10 = 0
Let's factor out the equation first.
x² - 7x + 10
x -2
x -5
This factoring of (x-2)(x-5) fit the equation.
(x-2)(x-5) = 0
One of the factors must equal 0 as to equal zero.
Either x - 2 = 0 or x - 5 = 0
x - 2 = 0
x = 2
x - 5 = 0
x = 5
The two answers are x = 2 or x = 5. Hope this helps!
