A reasonable estimate is an educated guess made by an observer based on that person's current knowledge and following observations. For example, If Garth knew that he was 1.2 meters tall, and he observed that the door was approximately twice his own height, Garth could then make the reasonable estimate that the door is about 2.4 meters tall.

What expression is represented by the factorization below (x+13)(x-13)
Lynna [10]

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,

[\frac {4,839}{15}] [where [x] is the greatest integer function on x]

= [322.6]

= 322

and the remainder is given by,

15 \times 0.6

= 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.

Find the volume of the portion of the solid sphere rholess than or equals5 that lies between the cones variant phiequalsStartFra
BlackZzzverrR [31]

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 = \frac{12!}{7!} = 12 x 11 x 10 x 9 x 8 = 96,040 different ways that can be made.
