The variable Z is inversely proportional to X. When X is 6, Z has the value 2.
Vera_Pavlovna [14]
Inverse proportion is of the form:

y=k/x, in this case the variables are

z=k/x, and we are given the point (6,2) so we can solve for k

2=k/6

12=k, so our equation is:

z=12/x, so when x=13

z=12/13

Please help it will be brainlist please make sure you are 100% the awnser is right
Dominik [7]

Answer:

Step-by-step explanation:

Step 1: Sum of angles on a straight line is 180

Step 2:

2x + 25 + y = 180

2x + y = 180 - 25

2x + y = 155  (1)

Step 3:

3x - 10 + y = 180

3x + y = 180 + 10

3x + y = 190    (2)

Step 4: Substract equation 1 from 2

3x + y - 2x - y = 190 - 155

      x = 35

Step 5:

Substitute x in equation 1 to find y

2x + y = 55

2(35) + y = 155

70  +  y = 155

  y = 155 - 70

   y = 85

Find the face value of the 20-year zero-coupon bond at 4.4%, compounded semiannually, with a price of $8,375.
umka21 [38]

<u>Given</u>:

Time,

t = 20 years

Rate,

r = 4.4%

Price

= $8,375

Now,

The yield will be:

= \frac{4.4}{2}

= 1.1 (%)

Time will be:

= 20\times 2

= 40 \ periods

As we know the formula,

⇒ Price \ of \ bond = \frac{Face \ value}{(1+\frac{r}{2} )^{n\times 2}}

By substituting the values, we get

                   8375=\frac{Face \ value}{(1+\frac{0.044}{2} )^{20\times 2}}

                   8375=\frac{Face \ value}{(1.022)^{40}}

                   8375=\frac{Face \ value}{2.3880083}

The face value will be:

        Face \ value = 2.3880083\times 8375

                           =20,000 ($)
