The Huey family is purchasing a winter cover for their above ground pool which is rectangular and has dimensions of 18 ft x 9 ft

Response:

B. 255 m

Detailed breakdown:

utilize similar triangles

L / 60 = 85 / 20

L = (85 * 60) / 20

L = 255 m

Answer:

y hat = 2114.20 + 18.96x

Step-by-step explanation:

Given the least squares regression model equation:

y hat = -959.00 + 8.60x

weld diameter x; shear strength y (in pounds)

1 lb = 0.4536 kg

To convert shear strength y to kilograms:

y is multiplied by 0.4536

(y hat × 0.4536) = -959.00 + 8.60x

Divide both sides by 0.4536

(y hat × 0.4536) / 0.4536= (-959.00 + 8.60x) / 0.4536

y hat = 2114.1975 + 18.959435x

y hat = 2114.20 + 18.96x

Explanation:

Hello! Please remember to formulate complete questions to receive accurate answers. I will assume that the depicted function derives from:

This describes the equation of a parabola that opens upwards, with its vertex positioned at:

The graph below illustrates this function. What is true about the graphed function f(x)?

• It is accurate that the domain consists of all real numbers, as this is a polynomial function.

• It is also correct that the range includes all real numbers where y ≥ 5

• It is indeed true that this parabola opens upwards

• It is valid to say it does not intersect the x-axis
