The value of y varies directly with the value of x, and y = 12 when x = 4.

1 answer:

8 0

You can basically plug in the numbers for x and y into the options:

A. y/x = 3
12/4 = 3, so this one is right

B. xy = 3
12*4 = 48, so this is wrong

C. x = 3y
3*12 = 36, which is not x (4), so this is wrong

D. y = 3x
3*4 = 12, which is y (12), so this is right

So, A and D are right

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:

$Face \ value = 2.3880083\times 8375$

$=20,000$ ($)

If a translation takes triangle CAT to C'A'T', what is A'T'?

Marina86 [1]

Answer:

square root of 10

Step-by-step explanation:

since triangle CAT with vertex A at negative 2 comma 1, vertex T at negative 1 comma 4 and vertex C at 0 comma 0, side AT has a measure of square root of 10 units, side TC has a measure of square root of 17 units, and side AC has a measure of square root of 5 units, therefore the square root will be 10
