Answers

Answer:

The radius of a sphere is 2 millimeters

The surface area of a sphere is 50.24 square millimeters.

The circumference of the great circle of a sphere is 12.56  millimeters.

Step-by-step explanation:

Verify each statement

case A) The radius of a sphere is 8 millimeters

The statement is false

we know that

The volume of the sphere is equal to

[tex]V=\frac{4}{3}\pi r^{3}[/tex]

we have

[tex]V=100.48/3\ mm^{3}[/tex]

[tex]\pi =3.14[/tex]

substitute and solve for r

[tex]100.48/3=\frac{4}{3}(3.14)r^{3}[/tex]

[tex]r^{3}=(100.48)/(4*3.14)[/tex]

[tex]r=2\ mm[/tex]    

case B) The radius of a sphere is 2 millimeters

The statement is True

(see the case A)

case C) The circumference of the great circle of a sphere is 9.42 square millimeters

[tex]r=2\ mm[/tex]  

[tex]\pi =3.14[/tex]

substitute

[tex]C=2(3.14)(2)[/tex]

[tex]C=12.56\ mm[/tex]

case D) The surface area of a sphere is 50.24 square millimeters.

The statement is True

Because

The surface area of the sphere is equal to

[tex]SA=4\pi r^{2}[/tex]

we have

[tex]r=2\ mm[/tex]  

[tex]\pi =3.14[/tex]

substitute

[tex]SA=4(3.14)(2)^{2}[/tex]

[tex]SA=50.24\ mm^{2}[/tex]

case E)  The circumference of the great circle of a sphere is 12.56  millimeters.

On December 31, 2016, Osborn Company purchased 30% of Shea Company’s common stock for $220,000. During 2017, Shea Company had a net income of $75,000 and paid cash dividends of $30,000. What would the balance of Osborn’s Equity Investment (Shea) account be at the end of 2017 if they use the equity method?A. $242,500 B. $211,000 C. $220,000 D. $233,500

Answers

Answer:

the balance of Osborn’s Equity Investment (Shea) account be at the end of 2017 is $233,500

Step-by-step explanation:

Given data

Acquistion price = $220000

purchased = 30%

net income = $75,000

cash dividends = $30,000

to find out

the balance of Osborn’s Equity Investment (Shea) account be at the end of 2017

solution

we will find out balance of investment i.e. given by formula

balance of investment = Acquistion price + share of income - share of dividend   .................1

so here

share of income = 30% of net income

share of income =30% × 75,000 = $22500    ..............2

and

share of dividend = 30% of cash dividends

share of dividend = 30% × 30000 = $9000  ...............3

put equation 2 and 3 in equation 1 and we get

balance of investment = Acquistion price + share of income - share of dividend

balance of investment = 220000 + 22500 - 9000

balance of investment = $233,500

A piece of thread is 52,000 nanometers thick. How many meters thick is the
thread? Write your answer in standard form.
1 nanometer = 1.0 x 10 meters​

Answers

Answer:

0.000052

1 nanometer = .000000001 meters

.000000001 x 52000 = 0.000052

To convert 52,000 nanometers to meters, divide by the conversion factor of 1,000,000,000 nanometers per meter, resulting in a thickness of 5.2 x 10-8 meters in standard form.

To convert the thickness of a piece of thread from nanometers to meters, we need to use the conversion factor that 1 meter equals 1,000,000,000 nanometers, or 1 m = 109 nm.

Using this conversion factor, we can set up the following calculation:

Thickness in meters = Thickness in nanometers \/ Conversion factor

Thickness in meters = 52,000 nm \/ (109 nm/m)

Thickness in meters = 52,000 nm \/ 1,000,000,000 nm/m

Thickness in meters = 0.000000052 m or 5.2 x 10-8 meters when expressed in standard form.

0, 5, −4
0, 5, 4

Answers

Final answer:

The zeros of the polynomial function f(x) = x^3 + x^2 + 20x are 0, -5, -4.

Explanation:

The zeros of a polynomial function are the values of x that make the function equal to zero.

We are given that one zero of the polynomial function f(x) = x^3 + x^2 + 20x is x = 0.

To find the other zeros, we can use polynomial long division or synthetic division to factor out x = 0 and find the remaining quadratic equation.

Factoring the quadratic equation, we find that the zeros are x = -5 and x = -4.

Therefore, the correct answer is 0, -5, -4.

Final answer:

The zeros of the polynomial function f(x) = x^3 + x^2 + 20x are 0, -5, and -4.

Explanation:

The zeros of a polynomial function are the values of x that make the function equal to zero. Given that one zero of the polynomial function f(x) = x^3 + x^2 + 20x is x = 0, we need to find the other zeros. To do this, we factor the polynomial using synthetic division or long division. In this case, the factored form of the polynomial is f(x) = (x)(x + 5)(x + 4). Therefore, the zeros of the polynomial function are 0, -5, and -4.

Six pairs of data yield r = 0.444 and the regression equation y = 5x + 2. also, y = 18.3. what is the best predicted value of y for x = 5?

Answers

Final answer:

The best predicted value of y for x = 5 is 27.

Explanation:

A regression equation is a mathematical model that represents the relationship between a dependent variable and one or more independent variables. It expresses the linear or nonlinear association between these variables and is derived from statistical methods like linear regression analysis.

To predict the value of y for x = 5 using the regression equation, you can substitute x = 5 into the equation y = 5x + 2:

y = 5(5) + 2 = 27

Therefore, the predicted value of y for x = 5 is 27.

The best predicted value of [tex]\( y \) for \( x = 5 \) is \( y = 27 \).[/tex]

To find the best predicted value of [tex]\( y \) for \( x = 5 \),[/tex]we substitute [tex]\( x = 5 \)[/tex] into the regression equation:

[tex]\[ y = 5x + 2 \] \[ y = 5(5) + 2 \] \[ y = 25 + 2 \] \[ y = 27 \][/tex]

To reconcile this discrepancy, if we assume that the provided value of [tex]\( y = 18.3 \)[/tex] corresponds to [tex]\( x = 5 \),[/tex] then we would set the regression equation equal to 18.3 and solve for \( x \):

[tex]\[ 18.3 = 5x + 2 \] \[ 16.3 = 5x \] \[ x = \frac{16.3}{5} \] \[ x = 3.26 \][/tex]

What must the total momentum of the system be after the train cars collide?

Answers

Answer:

The total momentum of the system remains the same.Momentum before collision is equal to momentum after collision

Step-by-step explanation:

Momentum is defined as the product of mass and velocity of the bodies.According to the law of conservation of momentum, a collision that occurs in an isolated system, the momentum before collision equals that after collision.After collision, the bodies can move in the same direction thus their momentum is combined.

Answer:

The total momentum must remain the same.

According to the law of conservation of momentum, in a system where particles collide, the momentum loss on one particles is gained by the other one. This is what create an reaction during the collision, for example, if two bodies collide, one will decrease its speed while the other will increase its speed, that's why the momentum is conserved.

So, basically, after the train cars collide, the momentum must be conserved, remaining the same.

The formula for the sum of an infinite geometric series with first term a1 and common ratio r (where |r| < 1) is ...

  sum = a1/(1 -r)

Applying this to the given series, we get ...

a. sum = 5/(1 -3/4) = 5/(1/4) = 20

b. sum = d/(1 -1/t) = d/((t-1)/t) = dt/(t-1)

_____

The derivation of the above formula is in most texts on sequences and series. In general, you write an expression for the difference of the sum (S) and the product r·S. You find all terms of the series cancel except the first and last, and the last goes to zero in the limit, because r^∞ → 0 for |r| < 1. Hence you get ...

  S -rS = a1

  S = a1/(1 -r)

Its in the picture below

a: 1% decay
b: 10% decay
c: 9% growth
d: 90% growth

Answers

Answer:

  b:  10% decay

Step-by-step explanation:

Expressed as a percentage change, the growth is usually the value of the base of the exponential function after 1 has been subtracted. That result is expressed as a percent:

  0.9 - 1 = -0.10 = -10% . . . . . 10% decay

_____

The "t/12" exponent means this is the decay that is experienced over 12 units of time. This might be the annual decay, where t is expressed in months, for example.
