The equation p = 1.65t² + 18.25t + 155 approximates the average sale price p of a house (in thousands of dollars) for years t si

liraira [26]

Answer:

The correct option is 2. The best estimate for the price of the house in year 2018 is $407,000.

Step-by-step explanation:

The given equation is

$p = 1.65t^2+18.25t+155$

Where p is the average sale price of house (in thousands of dollars) and t is number of years since 2010.

We have to find the best estimate for the price of the house in year 2018. The difference between 2018 and 2010 is 8 years.

Substitute t=8.

$p = 1.65(8)^2+18.25(8)+155$

$p = 1.65(64)+18.25(8)+155$

$p=406.6$

$p\approx 407$

Therefore the estimate for the price of the house in year 2018 is 407 thousand dollars, i.e.,$407,000. Option 2 is correct.

What is the length of the hypotenuse triangle if both sides are 36

vovikov84 [41]

Answer:

<h3> $\boxed{ \bold{ \huge{ \boxed{ \sf{36 \sqrt{2} \: \: units}}}}}$ </h3>

Step-by-step explanation:

Given,

Perpendicular ( P ) = 36

Base ( b ) = 36

Hypotenuse ( h ) = ?

Finding the hypotenuse  :

Using the Pythagoras theorem :

$\sf{ {h}^{2} = {p}^{2} + {b}^{2} }$

plug the values

⇒ $\sf{ {h}^{2} = {36}^{2} + {36}^{2} }$

Evaluate the power

⇒ $\sf{ {h}^{2} = 1296 + 1296}$

Add the numbers

⇒ $\sf{ {h}^{2} = 2592}$

Squaring on both sides

⇒ $\sf{h = 36 \sqrt{2} }$ units

Hope I helped!

Best regards!!
