The volume of a sphere is a function of its​ radius, V=4/3(pie)(r^3). Evaluate the function for the volume of a volleyball with radius 11.4cm

Answers

Answer 1
The sphere is indeed the set of all points situated at a distance in 3-D Subspace from a certain point. The diameter is two times termed the radius, and pairs of points are called antipodes on the opposite ends of the diameter.

Given:

Volleyball (sphere) volume[tex]=\bold{\frac{4}{3} \pi r^2}[/tex]

[tex]\to \bold{r=11.44\ cm}[/tex]

putting the value into the formula:

[tex]=\bold{\frac{4}{3} \times 3.14 \times 11.4^2}\\\\=\bold{\frac{4}{3} \times 3.14 \times 1481.544}\\\\=\bold{\frac{4}{3} \times 4652.04816}\\\\=\bold{4 \times 1550.68272}\\\\=\bold{6202.73}\\\\[/tex]

The Volume Of A Sphere Is A Function Of Its Radius, V=4/3(pie)(r^3). Evaluate The Function For The Volume
Answer 2
Final answer:

To find the volume of a volleyball with a radius of 11.4 cm, we plug the radius into the formula for the volume of a sphere, V=4/3(pi)(r^3), resulting in an approximate volume of 6185.7 cubic centimeters.

Explanation:

The question asks to evaluate the volume of a sphere using the given formula, which is V=4/3(pi)(r^3), where V represents the volume and r is the radius of the sphere. To find the volume of a volleyball with a radius of 11.4 cm, we substitute r with 11.4 in the formula and calculate the volume accordingly.

The calculation would be:

V = 4/3 × pi × (11.4 cm)^3
V = 4/3 × 3.14159 × 11.4 cm × 11.4 cm × 11.4 cm
V = 4/3 × 3.14159 × 1481.784 cm^3
V ≈ 4/3 × 3.14159 × 1481.784 cm^3
V ≈ 6185.7 cm^3

Therefore, the volume of the volleyball is approximately 6185.7 cubic centimeters.

Use the four-step procedure to solve the following problem. How much water must be added to a gallon of 10% saline solution to create a 2% solution?

Answers

We have 1 gallon of 10% saline.
How much water (x liters of 0% saline) must be added to make a 2% saline solution?
.10 * 1 + 0x = .02 * (1 +x)
.1 = .02 + .02x
.08 = .02x
x = 4 gallons of water must be added


Answer:

4 gallons of water should be added in 10% saline solution.

Step-by-step explanation:

Let x gallon of water is added in one gallon of 10% saline solution.

Therefore total volume of 10% saline solution will become (1 + x) gallons

Since concentration of water is 0% so equation will be

0.10(1) + 0(x) = .02(1 + x)

0.10 = 0.02(1 + x)

1 + x = [tex]\frac{0.10}{0.02}[/tex]

x + 1 = 5

x = 5 - 1

x = 4 gallons

Therefore, 4 gallons of water should be added to 10% saline solution to create 2% solution.

3x-2y=-39 and x+3y=31 solution using elimination

Answers

This is hard to write... I hope this makes sense to you...
3x-2y=-39
x+3y= 31
We want to use elimination therefor, we need to either get our x or our y to add together to get zero. 
To do this, we will multiply -3 to (x=3y=31) 
NEW EQUATION
3x-2y=-39 PLUS
-3x-9y= -93 Equals
Answer: -11y= -54 
y= 4.9
Plug in to solve for x (put new y in)
3x-2(4.9)=-39
x= -9.73 
Solving for x on 3x - 2y = -39:
First, we must add 2y to both sides.
3x - 2y + 2y = -39 + 2y
3x = 2y - 39
Next, we divide both sides by 3.
3x/3 = 2y - 39/3
Answer: 2/3y - 13

Solving for y on x+3y=31:
First, we must add -x to both of the sides.
x + 3y + -x = 31 + -x
3y = -x + 31
Next, we must divide both sides by 3. (Like last time.)
3y/3 = -x + 31/3
Answer: y = -1/3x + 31/3

Find the domain and range of the relation and determine whether it is a function. y=x2-3

Answers

is that supposed to be x squared or 2x
A relation is a set of pairs, like {(2, 1), (5, 9), (3, 7)}

If the first coordinate is not repeated, like in this example, were we have only (2, 1) and not also (2, 8), for instance, then the relation is called a function.


A relation sometimes has too many pairs to be expressed by listing all of them. in such cases we use formulas which describe all the pairs.

We are given the relation is [tex]y=x^2-3[/tex]. This means that all pairs of this relation, are such that the second coordinate, is the first one squared, minus 3.

So each pair of this relation is : [tex](x, x^2-3)[/tex]


For any x, [tex]x^2-3[/tex] is only one value, 

for example, if x=10, y can only be [tex]x^2-3=10^2-3=97[/tex]


We cannot possibly have both (10, 97) and (10, 16), for example, because the formula does not allow that.

this means 10 does not repeat as a first pair in this relation, and nor does any other value.


this makes the relation a function


The Domain is the set of all possible values x can be. Clearly, x can be any value, because no x makes [tex]x^2-3[/tex] undefined


Answer: The relation is a function, with Domain all real numbers


The set of ordered pairs represent a function. Write a rule that represent the function. (0,0), (1,6),(2,24), (3,54),(4,96)

Answers

All y coordinates are divisable by 6. What you then get is the square of x, so the function is:

f(x) = 6x²

The required function would be f(x) = 6x² which represents the set of ordered pairs.

What is a function?

The function is defined as a mathematical expression that defines a relationship between one variable and another variable.

We have been given that function as sets of ordered pairs :

(0,0), (1,6), (2,24), (3,54), (4,96)

First, we must identify a pattern. It appears that all yₓ values are multiples of 6.

We can divide yₓ by 6x since it is a multiple of 6 and a multiple of x:

y₁/ 6×1 = 1

y₂/ 6 ×2 = 2

y₃/ 6 ×3= 3

y₄/6×4 = 4

We can clearly see a pattern here ;

y/ 6×x = x

y = x × x × 6

y = 6x² = f(x)

Therefore, the required function would be f(x) = 6x² which represents the set of ordered pairs.

Answers

A linear equation has the form  y = mx + b where m and b are real numbers.  The value of b (you may know this as the y-intercept) is the value of y when x = 0. The value of m (the slope) is the RATE of increase; it tells how much y changes when x increases by 1.

In this problem, x represents the number of years since 2000, so x = 0 represents the year 2000.

Midwest: the value of y begins with 64.4 and increases by 0.3 each year.
y = 64.4 + 0.3x

West: the value of y begins with 63.2 and increases by 1.0 each year.
y = 63.2 + 1.0x

420,983 estimate it then estimate 39,932 then you have to add thoes then you have to add that and that and then you have to add 420,983 plus 39,932 and see if your answer is close to the estimate

Answers

Final answer:

By rounding numbers to the nearest large place value, we estimated the sum of 420,983 and 39,932 as 460,000. The exact sum is 460,915, demonstrating that our estimation was a close approximation to the actual value.

Explanation:

To estimate the sum of 420,983 and 39,932, we can round these numbers to the nearest ten thousand and thousand, respectively. Rounding 420,983 to the nearest ten thousand gives us 420,000, and rounding 39,932 to the nearest thousand gives us 40,000.

Now, we add the estimated numbers: 420,000 + 40,000 = 460,000.

To find the exact sum of 420,983 and 39,932, we add the two numbers together without estimating: 420,983 + 39,932 = 460,915.

Comparing our estimate of 460,000 with the exact answer of 460,915, we can see that our estimate is very close to the exact amount, showing that our estimation was a good approximation. To find the estimate for 420,983, we round it to the nearest 100,000, which is 400,000. For the estimate of 39,932, we round it to the nearest 10,000, which is 40,000. When we add these two estimates, we get 440,000. Next, we add the actual numbers 420,983 and 39,932, which gives us 460,915. Comparing this with our estimate, we can see that our answer is close to the estimate.

Final answer:

To estimate the sum of 420,983 and 39,932, round each number to the nearest thousand and add them together. Then compare the estimate with the actual sum.

Explanation:

To estimate the sum of 420,983 and 39,932, we can round each number to the nearest thousand. 420,983 rounded to the nearest thousand is 421,000, and 39,932 rounded to the nearest thousand is 40,000. Now, we can add these rounded numbers together: 421,000 + 40,000 = 461,000. This is our estimate for the sum.

Next, we add the actual numbers 420,983 and 39,932 together: 420,983 + 39,932 = 460,915. Finally, we compare our estimate (461,000) with the actual sum (460,915) to see if they are close. In this case, our estimate is slightly higher than the actual sum.

Solve the equation a+b-c=180 for c

Answers

We need to make sure c is on one side:

a + b - c = 180

So let’s subtract a and b from both sides:

-c = -a -b + 180

Now, multiply both sides by -1:

c = a + b - 180

Hope this helps!

Answer:

Step-by-step explanation:

we are given the equation a+b-c=180

Now to solve it for c we need to isolate the c

first step can be addition of c to  both side

a+b-c+c=180+c

a+b=180+c

now in second step we subtract 180 from both sides to get

a+b-180=180+c-180

a+b-180 = c

c= a+b-180
