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]

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%

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  ..

Answer:

9 1/8

Step-by-step explanation:

1. first take away the fraction part and take the whole numbers off of the numbers and add them!

1 + 3 + 5 =  9

2. now take that aside and keep that for later... now lets focus on the

1/2, 3/4, and the 1/8 these are the STARS you will be focusing on!

3. now, find the common denominator in these fractions!!!

how? here is how!

       1. lets list these fractions:

1/2, 3/4, and 1/8

the common demoninator is 8 because 1. its one of the highest in this set and 2. if you multiply 1/2 and 3/4 n the numerator and the demoentator by 4 they can create  a 8 denminator and then you can add them!

4. Next, I wont be explaning you just watch!

3        x2             6

_     =               _                  

4          x2            8    (to get to 8 from 4 you multiply by 2! so you do the same for the upper one!!!)

1      x4          4

_     =        _

2       x4        8

you dont do anything to 1/8 because its already part of the eights family! :D

5. I know, it took us a LONG way here but here it is! the final! now, time to add them!

     4/8, 6/8 and 1/8

6. lastly...

1 1/8 + 9 = 9 1/8

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.

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

D. 1/8

Step-by-step explanation:

Count the total sections - 8

Count how many 4s there are - 1

Reduce if possible, not possible here.

The probability of spinning getting 4 on the spinner will be 0.125.

Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.

The shinner has 8 equal sections.

The total number of events will be

Total event = 8 {1, 1, 1, 2, 2, 3, 3, 4}

Then the probability of spinning getting 4 on the spinner will be

Favorable event = 1 {4}

Then the probability will be

P = 1 / 8

P = 0.125

P = 12.5%

the complex number z=-2+10i

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.

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).

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.

Answer:

width is 48, length is 60

Step-by-step explanation:

Answer:  The dimensions of the field are

width = 40 ft and length = 60 ft.  

Step-by-step explanation:  Given that a field with an area of 2880 ft² has the shape of a rectangle with length 12 ft larger than the width.

We are to find the dimensions of the field.

Let w ft be the width of the given rectangular field.

Then, the length of the field will be (w + 12) ft.

According to the given information, we have

[tex]w \times (w+12)=2880\\\\\Rightarrow w^2+12w=2880\\\\\Rightarrow w^2+12w-2880=0\\\\\Rightarrow w^2+60w-48w-2880=0\\\\\Rightarrow w(w+60)-48(w+60)=0\\\\\Rightarrow (w-48)(w+60)=0\\\\\Rightarrow w-48=0,~~~w+60=0\\\\\Rightarrow w=48,-60.[/tex]

Since the measure of a side of a rectangle cannot be negative, so w = 48.

This implies that

length of the field = w + 12 = 48 + 12 = 60 ft.

Thus, the dimensions of the field are

width = 40 ft and length = 60 ft.

Answer:

(5x+3y) and (5x-3y)

Step-by-step explanation:

From the concept on difference between two squares;

a² - b² = (a+b)(a-b)

Therefore;

25x² - 9y² = (5x+3y) (5x-3y)

Therefore the dimensions of the square are (5x+3y) and (5x-3y)

Answer:

the dimensions of the rectangle are (5x + 3y) and (5x - 3y)

Step-by-step explanation:

The area of a rectangle is 25x^2 - 9y^2 square units.

To find the dimensions of a rectangle we need to factorize the expression completely.

We know that (a + b)(a - b) = a^2 - b^2

In this case: a^2 = 25x^2 and b^2 = 9y^2

So a = sqrt(25x^2) = 5x

And b = sqrt (9y^2) = 3y

Then the solution is:

(a + b)(a - b) = (5x + 3y)(5x - 3y)

Then the dimensions of the rectangle are (5x + 3y) and (5x - 3y)
