Tim Tradesman pays $2,000 annually for $150,000 worth of life insurance. Answer the following questions. a. At the end of 10 years, how much will Tim have paid in premiums? b. At the end of 10 years, what will the cash value of his policy be? c. What will the ratio of cash value to premiums paid be (as a percent)?

Answers

____________________________________________________

Explanation for question A:

We are trying to found the amount of money he payed after 10 years.

He pays an annual (yearly) of $2,000, so we would just multiply 2,000 by 10, since we are trying to find the amount he point in 10 years, in which he pays $2,000 a year.

[tex]2000*10=20000[/tex]

Answer for Question A: Tim Tradesman paid $20,000 in premiums at the end of 10 years.

____________________________________________________

Explanation for question B:

In question B, we are trying to find the cash value of the policy at the end of 10 years.

To find the cash value at the end of 10 years, we would get the units of life insurance and multiply it by the cash value per unit

There would be 150 units of life insurance.

So we multiply:

[tex]150*89=13350[/tex]

Answer for Question B: The cash value of his policy will be $13,350 at the end of 10 years.

____________________________________________________

Explanation for question C:

In question C, we are trying to find the ratio of cash value to premiums paid.

Our cash value is 13,350 and we paid 20,000.

When you subtract 20,000 and 13,350, you would get 6,650.

[tex]20000-13350=6650[/tex]

Then when you add 20,000 and 13,350, you would get 33,350.

[tex]20000+13350=33350[/tex]

When you subtract 6,650 from 33,350, you would get 26,700

[tex]33350-6650=26700[/tex]

26,700 is 66.75% of 33,350.

Answer for Question c: The ratio as a percent for the cash value to premiums paid is 66.75%

Given: m∠MEJ=30°, m∠MFJ=50° , Find: Measurement of Arc KL & Measurement of Arc MJ

Answers

Answer:

Part a) The measurement of arc KL is [tex]20\°[/tex]

Part b) The measurement of arc MJ is [tex]80\°[/tex]

Step-by-step explanation:

Let

x--------> the measure of arc KL

y-------> the measure of arc MJ

we know that

The measurement of the outer angle is the semi-difference of the arcs it encompasses.

[tex]m<MEJ=\frac{1}{2}(y-x)[/tex]

substitute the given value

[tex]30\°=\frac{1}{2}(y-x)[/tex]

[tex]60\°=(y-x)[/tex]

[tex]y=60\°+x[/tex] ------> equation A

The measure of the inner angle is the semi-sum of the arcs comprising it and its opposite.

[tex]m<MFJ=\frac{1}{2}(x+y)[/tex]

substitute the given value

[tex]50\°=\frac{1}{2}(x+y)[/tex]

[tex]100\°=(x+y)[/tex]

[tex]y=100\°-x[/tex] ------> equation B

Equate the equation A and B and solve for x

[tex]60\°+x=100\°-x[/tex]

[tex]2x=100\°-60\°[/tex]

[tex]x=20\°[/tex]

Find the value of  y

[tex]y=100\°-20\°=80\°[/tex]

therefore

The measurement of arc KL is [tex]20\°[/tex]

The measurement of arc MJ is [tex]80\°[/tex]

When Elyse moved last weekend, the circular glass top for an end table broke. To replace it, she bought a circular glass top with a diameter of 20 inches.

What is the approximate area of the circular glass top Elyse bought?

Answers

Answer:

A = 314 inches^2

Step-by-step explanation:

We know the diameter of the glass.  We need to find the radius

d = 2r

20 = 2r

Divide each side by 2

20/2 = 2r/2

10 =r

To find the area of the glass

A = pi r^2

A = pi * 10^2

A = pi*100

A = 100 *(3.14)

   = 314 in^2

A. 98/10; X =90
B. 98/10; =110
C. 10/98; X =90
D. 10/98; X= 110

Answers

Answer:

The statement which describes the ratio of weight to mass and the value of x is ⇒ 98/10 ; = 110 answer B

Step-by-step explanation:

* Lets explain how to solve the problem

- The mass (kilograms) values are

  20 , 50 , x , 130 , 140

- The corresponding weight (newtons) values are

  196 , 490 , 1078 , 1274 , 1372

* Lets find the ratio between weight to mass

∵ 196/20 ⇒ divide up and down by 2

196/20 = 98/10

∵ 490/50 ⇒ divide up and down by 10

∴ 49/5 ⇒ multiply up and down by 2

∴ 49/5 = 98/10

490/50 = 98/10

∵ 1274/130 ⇒ divide up and down by 13

1274/130 = 98/10

∵ 1372/140 ⇒ divide up and down by 14

1372/140 = 98/10

- All the ratios between weight to mass equal 98/10

∴ 1078/x = 98/10 ⇒ by using cross multiplication

∴ 98(x) = 1078(10)

∴ 98 x = 10780 ⇒ divide both sides by 98

x = 110

* The statement which describes the ratio of weight to mass and the

  value of x is 98/10; = 110

The ratio of weight to mass is constant. Write the ratio of weight to mass in simplest form to represent the table.  Answer: 9.8

What should the value of x be in the table? Answer 110 kilograms

Earth is approximately 9.3 × 107 miles from the sun. Saturn is approximately 8.87 × 108 miles from the sun. About how much farther is Saturn from the sun than Earth is?


Answers-
A)7.94 × 10 7 miles

B) 7.94 × 10 8 miles

C) 4.3 × 10 7 miles

D) 4.3 × 10 8 miles

Answers

Answer:

B) 7.94 × 10 8 miles

Step-by-step explanation:

Given

Distance between Earth and sun=E=9.3* 〖10〗^7  Miles

Distance Between Saturn and Sun=S=8.87* 〖10〗^8  Miles  

In order to find the distance between Earth and Saturn, we have to subtract the distance between earth and sun from the distance between Saturn and sun. So

Distance between Earth and Saturn=S-E

=(8.87* 10^8 )-( 9.3* 10^7 )

As the distances are in scientific notation, to perform subtraction, the powers of 10 in both quantities have to be same, so

=(8.87*10* 10^7 )-(9.3* 10^7 )

=(88.7* 10^7 )-(9.3* 10^7)

=79.4* 10^7  Miles

It can also be written as:

Distance between Earth and Saturn=7.94* 10^8 Miles  ..

Given that he polynomial function below find f(-9)

Answers

Answer:

B

Step-by-step explanation:

To find the value [tex]F(-9)[/tex] of the polynomial function [tex]F(x)=-x^2-10x-2,[/tex] you have simply substitute [tex]x=-9[/tex] into the function expression (write -9 instead of x):

[tex]F(-9)=-(-9)^2-10\cdot(-9)-2\\ \\=-81+90-2\\ \\=7[/tex]

Final answer:

To find f(-9) in the given function, substitute -9 for x and evaluate by following the transformation rules.

Explanation:

We can rewrite a given function as y = f{-2(x+1)}. To find f(-9), we substitute -9 for x in the function.

This gives us f(-9) = f{-2(-9+1)}. Calculating further results in f(-9) = f{-2(-8)}.

Therefore, to find f(-9), we evaluate the function at x = -8, and the value depends on the specific function provided.

If you increase your bicycle speed by 5.6 miles per hour, the speed will be 17.9 miles per hour. What is your bicycle speed now?

Answers

Answer:

12.3 mph

Step-by-step explanation:

17.9 - 5.6 = 12.3

Answer:

12.3 mph

Step-by-step explanation:

Let x be our speed now

We increase the speed by 5.6 mph

Our new speed is x+5.6

We are going 17.9 mph

x+5.6 = 17.9

Subtract 5.6 from each side

x+5.6 -5.6 = 17.9-5.6

x =12.3

Find a unit vector in the direction of u and opposite of u

Answers

Just divide [tex]\mathbf u[/tex] by its magnitude:

[tex]\|\mathbf u\|=\sqrt{5^2+6^2+(-1)^2}=\sqrt{62}[/tex]

So a unit vector in the direction of [tex]\mathbf u[/tex] is

[tex]\dfrac{\mathbf u}{\|\mathbf u\|}=\dfrac5{\sqrt{62}}\,\mathbf i+\dfrac6{\sqrt{62}}\,\mathbf j-\dfrac1{\sqrt{62}}\,\mathbf k[/tex]

Then multiply this by -1 to get a unit vector pointing in the opposite direction.

Final answer:

To find the unit vector in the direction of a vector u, divide each component by its magnitude. For a vector u=i+j, the unit vector direction is ½(i+j), and the opposite direction is ½(-i-j).

Explanation:

To find a unit vector in the direction of a given vector u, we must first calculate the magnitude (or length) of u and then divide each component of u by that magnitude. Let's assume the vector u has components i and j. The magnitude of u, denoted as |u|, is given by the square root of the sum of the squares of its components, which is √(i² + j²). The unit vector in the direction of u is then the vector u divided by its magnitude, Û = (i/|u|, j/|u|).

In the case of the vector u = i + j, the magnitude is √(1² + 1²) = √2, and so the unit vector in the direction of u is Û = ½(i + j). Conversely, the unit vector in the direction opposite to u would be Û = ½(-i - j) since we are simply negating each component of the unit vector in the direction of u.

Tomás built several towers with rectangular blocks. Which formula best represents the heights of the blocks in terms of their volumes?

Answers

Answer:

Option A

V = 15h

Step-by-step explanation:

Given in the question some information regarding the heights and volume of the towers with rectangular blocks

Formula to use

Volume = Length x Width x Height

30 =  Length x Width (2)

Length x Width   = 30/2

Length x Width   = 15

Formula best represents the heights of the blocks in terms of their volumes

V = 15h

Answer:

The correct answer is option A.  15h

Step-by-step explanation:

From the figure we can see that a table shows the relationship between heights and volume of rectangular blocks.

Heights          Volume

2                       15

3                       45

4                       60

10                    150

To find the formula in terms of heights

If height = 2 then volume = 30 = 2 * 15

If height = 3 then volume = 45 = 3 * 15

If height is 'h' then volume = 15 * h = 15h

The correct answer is option A.  15h

Answers

To compare the measures of variation for both weeks, calculate the range and standard deviation. Week 1 has a larger range and standard deviation compared to Week 2.

Explanation:

To compare and contrast the measures of variation for both weeks, we need to calculate the range and standard deviation for each week. The range is the difference between the highest and lowest values, while the standard deviation measures the average amount by which each data point differs from the mean.

For Week 1, the range is 90 (90 - 30), and the standard deviation is 25.62. For Week 2, the range is 30 (60 - 30), and the standard deviation is 11.55.

Therefore, Week 1 has a larger range and standard deviation compared to Week 2.

What is the amplitude, period, and phase shift of f(x) = −4 sin(2x + π) − 5?
Amplitude = −4; period = 2π; phase shift: x = -pie/2
Amplitude = −4; period = π; phase shift: x = pie/2
Amplitude = 4; period = π; phase shift: x = -pie/2
Amplitude = 4; period = 2π; phase shift: x = pie/2

Answers

Answer:

Amplitude = 4; period = π; phase shift: x = -pie/2

Step-by-step explanation:

For a sine wave of the following type:

y = Asin(Bx + C) + D, we have that:

A represents the amplitude

C represents the phase shift

D represents the vertical shift

And the period is given by: [tex]\frac{2 \pi}{B}[/tex]

Therefore, considering: f(x) = −4 sin(2x + π) − 5, we know that sin(a + π) = -sin(a). Then:

f(x) = −4 sin(2x + π) − 5 = 4sin(2x)-5 = 4cos(2x - π/2) - 5

The amplitude equals 4

The period is T = π

The fase shift is: -π/2.

Therefore, the correct option is:

Amplitude = 4; period = π; phase shift: x = -pie/2
