Answer:
V = 268 cubic inches
Step-by-step explanation:
[tex]V = \frac{4}{3} \pi r^{3}[/tex]
[tex]V = \frac{4}{3} \pi (4^{3} )[/tex]
[tex]V =\frac{4}{3}\pi (64)[/tex]
V = 268.0825731
V = 268
The volume of the sphere with radius 4 inches is V = 268.08 inches³
What is a Sphere?A sphere is symmetrical, round in shape. It is a three dimensional solid, that has all its surface points at equal distances from the center. It has surface area and volume based on its radius. It does not have any faces, corners or edges.
The Surface Area of a Sphere = 4πr²
The Volume of a Sphere = ( 4/3 ) πr³
where r is the radius of the sphere
Given data ,
Let the radius of the sphere be r = 4 inches
Let the volume of the sphere be V
So , Volume of a Sphere = ( 4/3 ) πr³
Substituting the given value of the radius, r = 4 in, we get:
V = (4/3)π(4³)
V = (4/3)π(64)
V = 268.08 inches³
Hence , the equation that finds the volume of the sphere is
V = (4/3)πr³ = (4/3)π(4³) = 268.08 inches³

There are men and women at a meeting.
There are 42 women.
40% of the people at the meeting are men.
Work out the total number of people at the meeting.
Answer:
70 peopleStep-by-step explanation:
40% of people are men, then 60% are women.
60% of x is 42 people, find x:
0.6x = 42x = 42/0.6x = 70Let total people be x
ATQ
[tex]\\ \sf\longmapsto 60\%\:of\:x=42[/tex]
[tex]\\ \sf\longmapsto 0.60x=42[/tex]
[tex]\\ \sf\longmapsto x=42/0.6=70[/tex]
Solve for x:
42=3x+6
Question 2 options:
x=-16
x=16
x=12
x=14
Answer:
42=3x+6
subtract 6 from both sides
42-6=3x+6-6
to get
36=3x
divide both sides by 3 to isolate x
36/3=3x/3
to get
12=x

If you take a varible, lets say x, and times that by your mom. You will get y^2. After that, take ur mom and divide that by ur dads ding dong. Now they don't give us the formula to find out how long, creamy and wet your dad's ding dong is so we use the formula, busty step sis + step bro = BIG DING DONG, to get (x^69)+12 as ur dads ding dong. Now add ur mom with ur dad, y^2+(x^69) to get a child, 6969699696.

#1 has to be excluded, since it jumps from 4 to 5 and has a hole between x=4 and x=5
#2 loses the extreme values. It would be correct if the domain was [tex]2<x<5[/tex]
#3 is including values in the interval [tex]1<x \leq 2[/tex] which aren't in our domain.

write a linear equation given the two points
Answer:
y = 2x + 1
Step-by-step explanation:
1. Find the slope; (change in y values)/(change in x values)
Slope = (-5 - 3)/ (-3 - 1) = -8/-4 = 2
2. Find the y-intercept (b) using the slope intercept formula: y = mx + b
m = 2 and using point (1, 3) , solve for "b"
y = mx + b
3 = 2(1) + b
3 = 2 + b
1 = b
3. Write the linear equation: y = 2x + 1
parallel, perpendicular, neither. 10x+8y=16 5y=4x-15
Answer:
Neither.

What is the slope and y-intercept -4x+2y=-2
Answer:
Slope: 2
Y-intercept: (0, -1) or - 1
Step-by-step explanation:
Given the linear equation, -4x + 2y = -2:
Transform the given equation into its slope-intercept form, y = mx + b:
-4x + 2y = -2
Add 4x to both sides:
-4x + 4x + 2y = 4x - 2
2y = 4x - 2
Divide both sides by 2 to isolate y:
[tex]\frac{2y}{2} = \frac{4x - 2}{2}[/tex]
y = 2x - 1 ⇒ This is the slope-intercept form where the slope, m = 2, and the y-intercept is (0, -1).
