Answer: v[5/7] represents the volume of air inside a rubber ball with radius 5/7 units, such that

Step-by-step explanation:

Given: The volume of air inside a rubber ball with radius r can be found using the function.

Here volume is a dependent variable on radius (independent variable).

Therefore, the value of v[5/7]  represents the volume of air inside a rubber ball with radius 5/7 units.

Answer:

we know that

The volume of a sphere (rubber ball) is equal to

V = 4/3pi r^3

where r is the radius of the sphere (rubber ball)

The volume in function notation is equal to

V(r) = pi r^3

in this problem we have

V(5/7)

that means

The radius of the rubber ball is 5/7 ft and the volume of the rubber ball is V(5/7) ft^3

<u>therefore, the answer is the option B</u>

the volume of the rubber ball when the radius equals 5/7 feet

vivado [14]

Answer:

a) Incorrect

b) $208

Step-by-step explanation:

a)

$4582 need to be distributed equally among 22 employees . Hence we need to divide 4582 by 22 to know the amount each one will get. Since 44=22*2 , The manager can estimate that each one of the employee will get around  $200 as bonus. So his reason to estimate was correct but the estimated amount was incorrect.

b)

Each employee will get

\frac{4582}{22}

= 208.27

Hence Each one will get

$208 rounded to nearest whole number

In the diagram, the areas of and are in a ratio of 3 : 4. What are the coordinates of point C?
Radda [10]

9514 1404 393

Answer:

  D.  (4, -6)

Step-by-step explanation:

Since the heights of both triangles are the same (CD), their areas are proportional to their bases. That is ...

  AC : CB = 3 : 4

In terms of coordinates, ...

  4(C -A) = 3(B -C) . . . . multiply the ratios by 4(CB)

  4C -4A = 3B -3C . . . .simplify

  7C = 4A +3B . . . . . . . isolate C

  C = (4A +3B)/7 . . . . . divide by 7

  C = (4(1, -9) +3(8, -2))/7 = (28, -42)/7 . . . . substitute given coordinates

  C = (4, -6)

31. The length of a rectangle is 2 meters less than
Effectus [21]

Answer:

l=15

Step-by-step explanation:

let length=l

width=w

l=3w-2

w=(l+2)/3

Perimeter P=2(l+w)=2[l+(l+2)/3]=2(4l+2)/3≤43

2(4l+2)≤129

8l+4≤129

8l≤125

l≤125/8

so l=15

________________

P=2(l+w)=2(3w-2+w)=8w-4≤43

8w≤47

w≤47/8

l≤141/8-2

l≤125/8

l=15
