You just purchased two coins at a price of $1,270 each. Because one of the coins is more collectible, you believe that its value
Karolina [17]

Answer:

The first coin will be worth $137.16 more than the second coin.

Step-by-step explanation:

Interest formula = i = prt

For coin #1:

p = 1270

r = 0.061

t = 18

i = (1270)(0.061)(18)

The first coin will be worth $2664.46 after 18 years.

For coin #2:

p = 1270

r = 0.055

t = 18

i = (1270)(0.055)(18)

The second coin will be worth $2527.30 after 18 years.

Subtract the value of coin #2 from coin #1.

2664.46 - 2527.30 = 137.16

In conclusion, the first coin will be worth $137.16 more than the second coin after 18 years.

Which of the following is the area of a quadrilateral with vertices at (-4,2),(1,2),(1,-3) and (-4,-3)
kow [346]

Answer:

The correct option is B.

Step-by-step explanation:

The given vertices are (-4,2),(1,2),(1,-3) and (-4,-3).

Plot these point on a coordinate plate. From the graph it is noticed that the given quadrilateral is a square.

Distance formula:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Use distance formula to find the side length.

AB=\sqrt{(1-(-4))^2+(2-2)^2}=\sqrt{5^2}=5

BC=\sqrt{(1-1)^2+(-3-2)^2}=\sqrt{(25}=5

Since both consecutive sides are equal therefore it is a square.

Area of a square is

A=a^2

Where, a is side length.

The side length of the square is 5. So, area of ABCD is

A=(5)^2

A=25

Therefore the area of quadrilateral is 25 units square. Option B is correct.

NISA [10]

Answer:

1,-10 and 2,-8

Step-by-step explanation:

If you substitute each answer choice:

6+-10=4

12+-8=4

12+8=4

6+2=4

The only ones that would make sense are the first and second one.
