radius and diameter
The Radius is the distance from the center outwards. The Diameter goes straight across the circle, through the center. The Circumference is the distance once around the circle.
Answer:
f(x) = + 8x² - 9
Step-by-step explanation:
Given the zeros of a polynomial say x = a and x = b, then
the corresponding factors are (x - a) and (x - b)
The polynomial is the the product of the factors
f(x) = (x - a)(x - b)
Given zeros x = 1, x = - 1, x = 3i and x = - 3i, then corresponding factors are
(x - 1), (x + 1), (x - 3i) and (x + 3i), then
f(x) = (x - 1)(x + 1)(x - 3i)(x + 3i) ← expand in pairs using FOIL
= (x² - 1)(x² - 9i²) → note i² = - 1, thus
= (x² - 1)(x² + 9) ← distribute
= + 9x² - x² - 9 ← collect like terms
= + 8x² - 9

10x7= 70 (Base 1)
10x7= 70 (Base 2)
10x4= 40 (Front)
10x4= 40 (Back)
7x4= 28 (Side 1)
7x4= 28 (Side 2)

Remember to think of a rectangular prism as a box, then label the base, the width, and the height :)
Answer: Given the quadratic equation + bx + c =0
If the value of a is positive, the the graph is a parabola with u - shape, that means minimum point will exist , but if the value of a is negative , then the graph will be a parabola with n - shaped , that is maximum point will exist
