new car is purchased for 18700 dollars. The value of the car depreciates at
14.25% per year. To the nearest year, how long will it be until the value of the
car is 3000 dollars?
The minimum time required to depreciate the value of the car is 12 years.
Let us assumed the time to be t. Representing the formula for calculation of time-
Final value = Principal value × [tex] {(1 - rate of depreciation)}^{t} [/tex]
Keeping the values in formula to find the time period
3000 = 18700 × [tex] {(1 - 14.25%)}^{t} [/tex]
Solving the expression
[tex] {(0.8575)}^{t} [/tex] = 3000/18700
Cancelling zeroes common in numerator and denominator
3000/18700 = [tex] {(0.8575)}^{t} [/tex]
Taking log on both sides of the equation
t log 0.8575 = 30/187
Keep the value
t = log 0.8575 30/187
t = 12 years
Hence, it will take 12 years for value depreciation.

if A C B, then A n B = A U B
1) sometimes

3) always
if A C B, then A n B = A U B is always true
How to determine if A C B, then A n B = A U BThe statement "if A C B, then A n B = A U B" can be rephrased as "if A is a subset of B, then the intersection of A and B is equal to the union of A and B".
Every element of A is also an element of B. Therefore, the intersection of A and B contains all the elements of A.
On the other hand, the union of A and B contains all the elements of A and all the elements of B. Since A is a subset of B, all the elements of A are already included in B, so the union of A and B is just equal to B.
Therefore, we have:
A n B = A (since all the elements of A are in both A and B)
A U B = B (since A is a subset of B)
So A n B = A U B = B, which means that the original statement "if A C B, then A n B = A U B" is true

C.220.06
D.2.65
Answer:
B. 122.88
Step-by-step explanation:
Since t is the number of years since 1910, we can find the t value we need for the equation by subtracting 1910 from 1980:
t = 1980 - 1910 = 70
Now, we can plug in 70 for t to find the amount of currency in 1980:
[tex]M(t)=2.08(1.06)^t\\M(70)=2.08(1.06)^7^0\\M(70)=122.8779348\\M(70)=122.88[/tex]

The square is dilated from the origin by a factor of 1111 to give A′B′C′D′A′B′C′D′.
What are the coordinates of point C′C′? (NEED THIS ASAP)
Answer:
Step-by-step explanation:
To dilate the square by a factor of 1111 from the origin, we need to multiply each coordinate by 1111.
The coordinates of point C are (8,8). So, to find the coordinates of point C' after dilation, we can simply multiply each coordinate by 1111:
x-coordinate of C' = 1111 * 8 = 8888
y-coordinate of C' = 1111 * 8 = 8888
Therefore, the coordinates of point C' are (8888, 8888).
We often use the phrase "to the power of" when talking about exponents. For example, x¹3 is
referred to as x to the power of 13. Why do you think that they would name it like this? How does
increasing the exponent of a number increase its "power"?
Hint: Use a number as an example. (for instance 2) if you keep increasing the power, what happens
to the answer? (i.e. compare 2¹, 2^2, 2^3, 2^4,..., 2^13, 2^14,... until you see the answer you are looking
for!)
In mathematics, the expression "to the power of" pertains to the exponent, signifying how many times a key number is to be multiplied by itself.
What is the exponents about?Expressing this idea in English can be done well by using the term "to the power of." To show this, 2 raised to the third power can be interpreted as 2 multiplied by itself three times, resulting in 8.
Therefore, the possible reason behind using the word "power" is probably due to the fact that when the exponent rises, the outcome number is wide, either being greater or smaller, made on the base being above or below 1. This implies that the figure holds more significant value.

The table below shows the lengths and weights of six dolphins at an aquarium. Use the data from Pax and Snowflake to create a linear model that predicts the weight (y) of a dolphin given its length (x). Which dolphin's weight differs most from the value predicted by this model?
The dolphin's weight that differs most from the value predicted by this model is JoJo's (31 lb of difference)
Let's elaborate the model this way:
Snowflake's length - Pax's length = 8.2 - 7.6 = 0.6 ft
Snowflake's weight - Pax's weight = 549 - 519 = 30 lb
Ratio = 30/0.6 = 50 lb/ft
This means that for every foot of length, the dolphin has a variable weight of 50 lb.
However, if we multiply the ratio by the actual length of the two dolphins, we will have these results:
Snowflake = 50 × 8.2 = 410
Pax = 50× 7.6 = 380
Snowflake = Actual weight - Ratio× Length = 549 - 410 = 139
Pax = Actual weight - Ratio × Length = 519 - 380 = 139
The common difference is 139.
Therefore, the linear model that predicts the weight (y) of a dolphin given its length (X) is:
y = 139 + 50x
Now, let's use the linear equation or model to calculate the weight of the remaining four dolphins, as follows:
Blaze y = 139 + 50 × 6.8 = 479 ⇒ difference of 9 lb (488 - 479)
JoJo y = 139 + 50 × 5.8 = 429 ⇒ difference of 31 lb (460 - 429)
Corky y = 139 + 50 ×8.4 = 559 ⇒ difference of 2 lb (559 - 557)
Shadow y = 139 + 50 × 7.4 = 509 ⇒ difference of 8 lb (509 - 501)
Hence, the dolphin's weight that differs most from the value predicted by this model is JoJo's (31 lb of difference)

The angles that you get when a circle is divided into 4 equal parts, would be four 90 degree angles.
How to describe the angles ?The reason these angles are called 'right angles' is because they create an exact 90-degree angle, signifying one fourth of a complete circle. Every specific angle is named as a 'quadrant,' as it covers a quarter or a quadrant of the circle.
These four perpendicular angles stand side by side - having in common not just one diameter of the circle but also a shared vertex, which is at the center of the circle. Together, they share uniformly the circle into four unique sections - each turning toward a distinct quadrant of the circle parallel to their placement.
