a. The difference between two outputs that are 1 unit apart.

You need to Use y2 - y1 / x2 - x1 to find the difference

I will choose x2 as 1 and x1 as 0

(29 - 21) / (1 - 0)

8/1 so The difference is 8 per 1 unit.

b. Use the same formula

I will choose -3 as x2 and -5 as x1

(5 - (-11)) / (-3 - (-5))

(5 + 11) / (-3 + 5)

16 / 2 so the difference is 16 per 2 units.

c. I will choose 2 as x2 and -1 as x1

(45 - 21) / (2 - (-1))

24/3 so the difference is 24 per 3 units.

d. The ratios of the differences to the input intervals reduced all equal each-other, which is 8 per 1 unit.

Kingbird, Inc. purchased merchandise with an invoice price of $3200 and credit terms of 2/9, n/30. Assuming a 360-day year, what

Tatiana [17]

Answer:

80%

Step-by-step explanation:

Data provided as per the question

Number of days in a year = 360 days

Discount provided = 2%

Total net credit period = 30

The calculation of implied annual interest rate inherent in the credit terms is shown below :-

$Inherent\ in\ the\ credit\ terms\ = \frac{Number\ of\ days\ in\ a\ year}{Total\ net\ credit\ period\ - Remaining\ days}\times 2\%$

$Inherent\ in\ the\ credit\ terms\ = \frac{360}{30 - (30\ -\ 9)}\times 2\%$ $Inherent\ in\ the\ credit\ terms\ = \frac{360}{30 - 21}\times 2\%$

$Inherent\ in\ the\ credit\ terms\ = \frac{360}{\ 9}\times 2\%$

$Inherent\ in\ the\ credit\ terms\ = \ 40\times 2\%$

$Inherent\ in\ the\ credit\ terms\ = \ 80\%$

Therefore for computing the inherent in the credit terms we simply applied the above formula.

3x - 2y = 13 x + 4y = 14

AleksandrR [38]

Answer:

10x +6y - 14

Step-by-step explanation:

3x - 2y = 13x + 4y = 14

3x = 13x + 6y = 14

-10x = 6y = 14

10x + 6y - 14

Hailey is scuba diving in the ocean. Her boat is anchored 300 feet away at a 30° angle of depression. If her diving partner is 2

victus00 [196]

Answer:

B)313 ft

Step-by-step explanation:

Hello,I think I can help you with this

to solve this you need to find all the measures of the rigth triangle formed by Hailey, the boat, and the point on the surface of the sea just above the head of Hailey

Step 1

define

triangle

Hypotenuse=300 feet

opposite side=y

adjacent side=x

angle of depression =30°

Step 2

find the distances

$cos\alpha =\frac{adjancent\ side}{hypotenuse}\\\\hypotenuse*cos\alpha =adjancent\ side\\ so\\x=adjancent\ side=hypotenuse*cos\alpha\\\\x=300\ft*cos 30 \\\\x=259.8076$

so, the point on the surface of the sea just above hailey is 259.8076 ft from the boat

$sin\alpha =\frac{opposite\ side}{hypotenuse}\\\\hypotenuse*sin\alpha \\y=opposite\ side\\ so\\y=opposite\ side=hypotenuse*sin\alpha\\\\y=300\ft*sin 30 \\\\y=150$

hailey is at a depth of 150 feet

Step 3

now,her partner is 25 feet directly below her,it is

partner's depth is =hailey is at a depth of 150 feet+25

Y=175

he is at the same distance from de boat ( horizontal),because it is the same point in the sea surface.

X=259.80

Step 4

to find the distance between the partner and the boat we can use

Pythagoras theorem

$adjacentside^{2} +opposite side^{2} =hypotenuse^{2} \\\sqrt[2]{adjacentside^{2} +opposite side^{2}} =Hypotenuse\\Hypotenuse=\sqrt[2]{175^{2} +259.8076^{2}} \\\\Hypotenuse=313.24 ft$

so, Hailey's diving partner is 313 ft away from the boat(B)

Have a great day.
