Answer:

  D  The model indicates that 1-bedroom apartments in New York had an average rent of 800 dollars in 2000.

Step-by-step explanation:

The y-axis of the graph represents the year 2000. The value on that axis represents the rent for a 1-bedroom apartment. So, the y-intercept of 800 means ...

  1-bedroom apartments in New York had an average rent of 800 dollars in 2000

The best interpretation of this y-intercept is the model indicates that 1-bedroom apartments in New York had an average rent of 800 dollars in 2000.

The intersection of the graph of the function with the y-axis gives y-intercept of that function.

The y-intercept is the value of y on the y-axis at which the considered function intersects it.

Thus, y-intercept of y = f(x) is y = f(0)

In this case, x be the number of years after the year 2000.

Then we can show that x = 0, represents the year 2000 itself.

Now, the y-intercept is the value of y when we have x = 0.

So, the y-intercept gives information about the average price of a 1-bedroom apartment in the year 2000.

The information that we can conclude with this is the model indicates that 1-bedroom apartments in New York had an average rent of 800 dollars in 2000.

Answer:

( 7x + 11  )( 7x-  11 )

Step-by-step explanation:

( 7x + 11  )( 7x-  11 )

Because 7*7 is 49

-11*11= -121

7*11=77

-7*11= -77

77-77=0

so the answer is 49x^2-121

To factorize 49x^2-121, we can apply the difference of squares method. The factorization of 49x^2-121 is (7x + 11)(7x - 11).

To factorize the quadratic expression 49x^2 - 121, we first identify it as a difference of squares. This allows us to rewrite it as (7x)^2 - 11^2. Utilizing the difference of squares factoring pattern, we then break it down as (a + b)(a - b), where in this case, a = 7x and b = 11. Consequently, the factorization of 49x^2 - 121 simplifies to (7x + 11)(7x - 11). This method efficiently breaks down the quadratic expression into its constituent linear factors, providing a clearer representation for mathematical analysis and problem-solving purposes.

The measure of the hypotenuse of an isosceles triangle with equal sides measureing 12 units is 16.97 units

An isosceles triangle is a triangle that has two of its sides equal to each other . The base angle is also equal to each other.

The isosceles triangle is a right triangle. Since, one of the leg is 12 units, the other leg is also 12 units.

Using pythagora's theorem,

c² = a² + b²

c = √12² + 12²

c = √144 + 144

c  = √288

Answer:

Hey!

If a car is losing value at a constant rate, then a linear function would work better. For example, say that a car dealership is buying used cars. They will buy it for the asking price, but subtract 500 dollars for each year the car has been in existence. So, if you had a car from 2015 that cost you $2,000, and it's 2018, the dealership would buy it for 2000-(500 * the amount of years it has been since the car was made). Therefore, as 2018-2015=3, we have 2,000-500*3=2,000-1,500=500 as the value of the car after three years, and linear function (in the form of

, with y representing the end cost, b representing the starting cost, m representing the amount the car depreciates in value every year, and x being the amount of years) is 500=(-500*3+2000) in our situation here. Similarly, if the minivan depreciates 3,000 dollars in the first year, based on our knowledge and being forced to use linear function, we can assume that the minivan loses 3,000 dollars every year, making our equation y=(-3000*x)+29,248, with y representing the value of the car at the end, x representing the amount of years, and b representing the starting cost.

However, say that the car loses 50% of its value every year. This means that if you originally bought a car for 2,000 dollars in 2015, in 2016 it would be world 2,000/2=1,000 , 1,000/2=500 the year after that, and so on. We can try to put this into a linear function, but it's hard to put into one equation because we're not subtracting or adding to the cost of the car by a specific amount each year. If we had our equation as y=-0.5*x+2000, this wouldn't work because it's adding to the original amount, not multiplying. However, if we used an exponential equation such as y=b(m^a), with y representing the end cost, b representing the starting cost, m representing the amount multiplied per year, and a representing the amount of years. This works because we start with a value, and multiply it by an amount each year. Since 50%=0.5, we plug that into m to get y=2,000(0.5^a). Therefore, this works really well here. If the minivan were to depreciate by 3,000 every year, starting at $29,248, this means that we first have to find out what we multiply 29,248 by the first year to subtract 3,000. As, after one year, the value is 29,248-3,000=26,248, we have 26,248=29,248(m^1). Therefore, we can divide 29,248 by both sides to get around 0.9 as our answer for m. Thus, our equation is y=29,248(0.9^a). This type of equation would not work if we subtracted an amount every year because we're not multiplying by the same amount then. For example, if a toy was valued at 3$ and gained a value of one dollar every year, we could multiply the toy by 4/3 the first year to get 4, but the next year we wouldn't get 5.

Hope it helps you in your learning process.

The probability of first drawing a ball numbered 9 and then drawing a ball numbered 3, with each ball being returned to the box between draws, is 1 in 225.

The question is about calculating the probability of two specific events occurring consecutively when drawing billiard balls from a box that contains numbers 1 through 15. We focus on the probability of first drawing a ball numbered 9 and then, after returning it, drawing a ball numbered 3. Since each ball is returned to the box before the next draw, the number of possible outcomes does not change between draws.

For the first draw, the probability of drawing a 9 is 1 out of 15 (since there is one '9' ball and 15 total balls). When the 9 ball is returned, the probability of drawing a 3 on the second draw is also 1 out of 15. Because these two events are independent (the outcome of the second draw does not depend on the outcome of the first), we multiply the probabilities of each event to find the overall probability of both events occurring:

Probability of drawing a 9 and then a 3 = (1/15) * (1/15) = 1/225.

This means there is a 1 in 225 chance of drawing a 9 followed by a 3 when both balls are returned to the box in between draws.

The lengths of the sides corresponding to DE and DF in triangle ABC are 3.75cm and 5cm respectively as triangles DEF and ABC are similar and their sides are in proportion.

Since triangles DEF and ABC are similar, then their corresponding side lengths are proportional. This means the ratio of the lengths of corresponding sides in both triangles remains constant.

Therefore, the lengths of the corresponding sides in triangle ABC will be in the same ratio as that of the sides in triangle DEF. Since we know the lengths of sides DE and DF in triangle DEF are 6cm and 8cm respectively, we can conclude that the lengths of the sides corresponding to DE and DF in triangle ABC will be in the same ratio as 6 and 8.

The ratio of 6 and 8 can be simplified to 3:4. Therefore, given that the length of side EF in triangle ABC is 5cm, we can apply cross-multiplication to find the lengths of the other sides. For example, using the ratio 3:4 to find the length corresponding to DE in triangle ABC, we would get 5/4 * 3 = 3.75cm. Similarly, "for DF we would get 5/4 * 4 = 5cm".

The lengths of sides DE and DF in triangle DEF are 6 cm and 8 cm, respectively.

Since triangle DEF is similar to triangle ABC, the corresponding sides of both triangles are proportional. This means that the ratio of any two corresponding sides in the two triangles will be the same. Let's denote the lengths of the corresponding sides in triangle ABC as follows: side AB corresponds to DE, side BC corresponds to EF, and side AC corresponds to DF.

Given that EF is 5 cm, we can set up the following proportion using the corresponding sides of the two triangles:

[tex]\[\frac{DE}{AB} = \frac{EF}{BC} = \frac{DF}{AC}\][/tex]

We know the lengths of DE and DF, so we can express the lengths of AB and AC in terms of the lengths of DE and DF, using the proportion:

[tex]\[\frac{6}{AB} = \frac{5}{BC} = \frac{8}{AC}\][/tex]

From the proportion, we can solve for AB and AC:

[tex]\[AB = \frac{6}{5} \times BC\][/tex]

[tex]\[AC = \frac{8}{5} \times BC\][/tex]

Since we do not have the actual length of BC, we cannot determine the exact lengths of AB and AC. However, we can express them in terms of BC, the corresponding side in triangle ABC. If BC is known, we can simply multiply it by the respective ratios to find AB and AC.

In conclusion, the lengths of sides DE and DF in triangle DEF are 6 cm and 8 cm, respectively, and the lengths of the corresponding sides AB and AC in triangle ABC can be calculated once the length of BC is known, using the ratios derived from the similarity of the triangles.
