Answer:

x = 5.6
y = 65

Step-by-step explanation:

There are a couple of relations that are applicable to these questions.

the product of segment lengths of crossed chords is the same for both chords
the angle formed at crossed chords is the average of the intercepted arc measures

The segment lengths relation tells us ...

10x = 8×7 . . . . . . products of segment lengths are equal

x = 56/10 = 5.6 . . . . divide by 10

The value of y° is the average of the intercepted arcs:

y° = (85° +45°)/2 = 65°

_____

<em>Additional comment</em>

This diagram does not have enough information to allow computation of z. We would need to know the intercepted arc, or the length of the secant that meets tangent z.

Summer has an offer to buy an item with a sticker price of $13,200 by paying $460 a month for 36 months. What interest rate is S

AysviL [449]

Answer:

the annual interest rate is 7.583%

Step-by-step explanation:

We are given

Summer has an offer to buy an item with a sticker price of $13,200

so, we have

P=13200

paying $460 a month for 36 months

so, we can find total amount

$A=460\times 36$

$A=16560$

Let's assume

annual interest is r

total time =36 months

so, total number of years =3

Since, it is compounded monthly

so, n=12

now, we can use formula

$A=P(1+\frac{r}{n} )^{nt}$

now, we can plug values

$16560=13200(1+\frac{r}{12} )^{36}$

now, we can solve solve for r

$(1+\frac{r}{12} )^{36}=\frac{16560}{13200}$

$r=0.07583$

So, the annual interest rate is 7.583%
