1question. 11 points. for the the equation p = 1.7t² + 18.75t + 175 approximates the average sale price p of a house (in thousands of dollars) for years t since 2010. what is the best estimate for the price of the house in year 2020

The equation approximates the average sale price p of a house (in thousands of dollars) for years t since 2010.

We have to calculate the best estimate for the price of the house in year 2020.

So, we have to calculate the best price of the house after 10 years.

So, putting the value t=10 in the given equation.

p = 532.5= 533 (Rounded)

Since it approximates the average sale price p of a house (in thousands of dollars).

Therefore p=$533,000

Therefore, the best estimate for the price of the house in year 2020 is $533,000.

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
