After a new $28,000 car is driven off the lot, it begins to depreciate at a rate of 18.9% annually.

REY [17]

Answer:

C(t) = $28,000(0.811)^t (Answer A)

Step-by-step explanation:

The value of the car is decreasing. Thus, by the end of the first year of ownership, the car will have the value $28,000(1 -0.189)^1, where the "-0.189" represents DECAY instead of GROWTH.

Please use " ^ " to indicate exponentiation.

Then the desired formula is C(t) = $28,000(0.811)^t (Answer A)

Bryce is looking at a map of a theme park. The map is laid out in a coordinate system. Bryce is at (2, 3). The roller coaster is

Sunny_sXe [5.5K]

Answer:

Bryce is closer to the <u>roller coaster</u> as compared to the water ride.

Step-by-step explanation:

Given :

Bryce is at point (2,3)

Roller coaster is at point (7,8)

Water ride is at point (9,1)

To find whether Bryce is closer to roller coaster or the water ride.

Solution.

In order to determine the closeness of Bryce from either of the two rides, we will need to find the distance of Bryce from each of them. We can apply distance formula in order to do so.

By distance formula to find distance between two points $(x_1,y_1)$ and $(x_2,y_2)$ .

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

Distance between Bryce (2,3) and roller coaster (7,8) can be given as:

$d_1=\sqrt{(7-2)^2+(8-3)^2}$

$d_1=\sqrt{(5)^2+(5)^2}$

$d_1=\sqrt{25+25}$

$d_1=\sqrt{50}$

$d_1=7.07$ units

Distance between Bryce (2,3) and water ride (9,1) can be given as:

$d_2=\sqrt{(9-2)^2+(1-3)^2}$

$d_2=\sqrt{(7)^2+(-2)^2}$

$d_2=\sqrt{49+4}$

$d_2=\sqrt{53}$

$d_2=7.28$ units

Thus, we can see that Bryce is closer to the roller coaster as compared to the water ride.

Margaret has a monthly clothes budget of $50. She maps the amount of money she spends each month to the number of items of cloth

prisoha [69]

Margaret has a monthly clothes budget of $50. This implies that she can spend a maximum of $50 on clothes and therefore the maximum value of the domain is 50 to or it can also be said that the domain is all values of domain from 0 to 50.

jasmine needs 300 centimeters of fabric to make her new dress. The fabric costs $5 for each meter. How much will her fabric cost

Fed [463]

The cost of 300 cm fabric is $15.

Step-by-step explanation:

Given,

Cost of fabric is $5 per meter.

To find the cost of 300 cm fabric.

1 m = 100 cm

We will apply unitary method.

Cost of 100 cm of fabric is $5

Cost of 1 cm of fabric is $ $\frac{5}{100}$

Cost of 300 cm of fabric is $ $\frac{5}{100} X300$

= $ 15

Hence,

The cost of 300 cm fabric is $15.
