<h3>Answer:  B) 36π cubic inches</h3>

=====================================

Work Shown:

V = volume of the sphere

V = (4/3)*π*r^3

V = (4/3)*π*(3)^3

V = (4/3)*π*27

V = (4/3)*27*π

V = ((4*27)/3)*π

V = (108/3)π

V = 36π

Solve the simultaneous equations<br> y-2x=6<br> y+2x=0
elena-14-01-66 [18.8K]
Y-2x=6 => y=6+2x
Y+2x=0
(6+2x) + 2x = 0
6 + 4x = 0
4x= 6
X=6/4
X= 3/2
Y=6+2x
Y=6+2. 3/2
Y= 6 + 3
Y=9
Check: y-2x=6
9-2. 3/2 = 6
9 - 3 = 6

Write the equation of the line that passes through the points (-1, 10) and (5, 2)
sdas [7]

Answer:

y=-\frac{4}{3}x +\frac{26}{3}

Step-by-step explanation:

1) if the point A has coordinates (-1;10) and the point B - (5;2), then it is possible to write common view of the required equation of the line:

\frac{x-X_A}{X_B-X_A} =\frac{y-Y_A}{Y_B-Y_A};

2) if to substitute the coordinates of A&B into the common equation, then:

\frac{x+1}{5+1} =\frac{y-10}{2-10}; \ => \frac{x+1}{6}=\frac{y-10}{-8};

3) finally, in slope-intersection form:

3y= -4x+26; ⇔ y= -4/3 x +26/3.

P.S. the suggested way of the solution is not the only one.

A television game show begins with 20 contestants. Each week, the players vote 2 contestants off the show. What is the rate of c
nadya68 [22]

Using a linear function, it is found that the rate of change in this problem situation is of -2 contestants per week.

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = mx + b

In which:

  • m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

Considering the situation described, the number of participants after n weeks is given by:

N(n) = 20 - 2n.

The slope is of -2, hence the rate of change in this problem situation is of -2 contestants per week.
