Sidana [21]

Answer:

Step-by-step explanation:

Draw a picture of a cube and label the cube's side length, s. Prior to placing your order for more cardboard, tape, packing material, etc. your boss asked you to determine each of the following: a. Write an expression to determine the surface area of a cube-shaped box, SA, in terms of its side length, s (in inches).

The surface area of a cube of side length s is A = 6s^2; there are 6 sides each of area s^2.

If s is measured in inches, then A = 6x^2 inches^2.

b. Define a formula to determine the volume of a cube-shaped box, V, in terms of its side length, s, (in inches). Preview What are the units for the cube's volume?

The formula for the volume of a cube is V = s^3. In this case, V is measured in inches^3.

c. Given the formula for determining the volume of a 4 sphere is V = ar atrs, 3 (This is incorrect; the formula in question, for the volume of a sphere of radius r is V = (4/3)(pi)r^3. (1) We can solve this formula for r^3, and then for r:

3V

3V = 4(pi)r^3 becomes r^3 = ------------

4(pi)

and so the formula for the radius of a sphere whose volume is 87 inches^3

is

∛(3V) ∛3*87 in^3

r = ------------ = ------------------

∛(4pi) ∛(4pi)

(2) The volume of the sphere when r = 5.9 in is:

4(3.14) 205.38 in³

(4/3)(pi)r^3 = (4/3)(pi)(5.9 in)³ = --------- = --------------------- = 67.46 in³

3 3

(3) V = (4/3)(pi)r³

Please share the possible answer choices. Basically, you must find the volume twice: once for a radius of 4 in and once for a radius of 2 in. Then subtract the smaller from the larger. The numerical result is the desired answer.

Lesson 1-1: The periodic comet named Johnson has been seen at every return since its discovery in 1949, as shown in the table be

stiks02 [169]

Answer:

Step-by-step explanation:

Occurrence Year seen Difference

1 1949 -

2 1956 1956 - 1949 = 7

3 1963 1963 - 1956 = 7

4 1970 1970 - 1963 = 7

Difference between each successive term of year seen = 7 years

Therefore, there is a common difference of 7 years between each successive term.

Function defining the year seen will be a linear function and will increase in the same pattern. (multiple of 7 years)

2017 - 1970 = 47 (It's not the multiple of 7)

2018 - 1970 = 48 (It's not the multiple of 7)

2019 - 1970 = 49 (multiple of 7)

2020 - 1970 = 50 (It's not the multiple of 7)

Therefore, comet will be seen next in 2019.

Option (C) will be the answer.

If a person is born in 2005

Then difference between 2005 and 1949 = 56 years

Number of times comet seen after 1949 = $\frac{56}{7}=8$ times

Total number of comet seen in the lifetime = 8 times
