Answer:
A
Step-by-step explanation:
note that these are the factors of a difference of squares
• a² - b² = (a + b)(a - b), hence
(x + 13)(x - 13)= x² - 13² = x² - 169 → A
Answer:
The first digit of the quotient should be placed at the leftmost place of the places of the all the digits in the quotient.This is so from the basic rule of division.
Step-by-step explanation:
The quotient is given by,
[where [x] is the greatest integer function on x]
= [322.6]
= 322
and the remainder is given by,

= 9
So, the first digit of the quotient should be placed at the leftmost place of the places of the all the digits in the quotient and this is so from the very basic rule of division.
Answer:
Volume = (250π√3)/3 unit³
Step-by-step explanation:
The shape is a solid sphere
Where rho = ρ
ρ ≤ 5
Where Phi = φ
φ = π/6 (lower limit)
φ = 5π/6 (upper limit)
Note 1π rad = 180°
We would apply triple integrals and spherical coordinates to solve for the volume of a solid sphere.
See attachment for details
From calculations,
The volume of the portion of solid sphere = Volume = (250π√3)/3 unit³
To solve this problem, we will use the formula for permutation. A permutation is where the order of the things in the set matter.
Solution:
₁₂P₅ =

= 12 x 11 x 10 x 9 x 8 = 96,040 different ways that can be made.
