Answer:

y = 100°

Step-by-step explanation:

x = 40° (vertical angles are congruent)

y is an exterior angel of a triangle that has two opposite internal angles, x (40°) and 60°.

According to the exterior angle of a triangle, thus:

y = 40 + 60

y = 100°

Leona purchased a $1,000 bond having a quoted price of 99.875. She had to pay a 5.5% brokerage fee (of the selling price). What
iogann1982 [59]

Answer:

None of these choices are correct.

Step-by-step explanation:

If a bond is quoted at 99.875, it means that it is sold at 99.875%  of the face value;

Face value = 1000

Therefore, Price = 0.99875 * 1000

Price = $998.75

If Leona pays  5.5% of the selling price, it means that she is paying additional cost which will make the total cost more than the quoted price;

5.5% of 998.75 is;

0.055*998.75 = $54.93

The total cost = $998.75 +$54.93

= $1053.68

Therefore, none of the given choices is correct.

Texaschic nailed it when saying that it's arithmetic

The recursive way to write this is to say

a_1 = 6
a_n = a_{n-1} - 5

which tells us "start at 6 and each time subtract off 5"

The a_n portion is the nth term while a_{n-1} is the term just before the nth term

I NEED HELP!!! ASAP!!!
omeli [17]

Answer:

A.

Step-by-step explanation:

In the picture, the estimated slope goes down, so it has to be negative, eliminating 2, B and D

It isn't a gradual line, as 6x is, so that is eliminated.

When we look at the estimated line, we can count out on the grid 3 to the right and 4 down, doing that a few times.  If you then connect the dots, it will be a line probably very close to your estimate.

The explicit formula for a sequence is
Alexandra [31]

Answer:

28

Step-by-step explanation:

Let n = 21, and evaluate the expression.

a_n = -2 + \dfrac{3}{2}(n - 1)

a_{21} = -2 + \dfrac{3}{2}(21 - 1)

a_{21} = -2 + \dfrac{3}{2}(20)

a_{21} = -2 + \dfrac{3}{1}(10)

a_{21} = -2 + 30

a_{21} = 28
