Equations y1 = x2 − 5x + 8 and y2=10/x intersect at a point. What is the closest value of x when y1 = y2?

Alex17521 [72]

Answer:

C. between 3.5 and 4

Step-by-step explanation:

We are given

$y_1=x^2-5x+8$

$y_2=\frac{10}{x}$

Since, we have to solve for x

so, firstly we will set them equal

$x^2-5x+8=\frac{10}{x}$

we can multiply both sides by x

and we get

$x^3-5x^2+8x=10$

now, we can use graphing calculator

and find intersection point between y1 and y2

so, we can see that

x=3.538 lies between 3.5 and 4

so,

C. between 3.5 and 4

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.

Omg someone pleaseeee help me!!! 30 points!!!

Crank

add the volume of a cone, V=1/3 pi times radius squared times h. The volume of the cone is V=355. Then you add the volume of the cone to the volume of the cylinder. the formula for the volume of a cylinder is V= pi times radius squared times h. So the volume of the cylinder will be V=923. if you add those two together the overall volume is 1,278.
