A scale drawing of a rectangular park is 5 inches wide and 7 inches long. The actual park length is 280 yards. What is the width
Anastaziya [24]

Answer:

56,000

Step-by-step explanation:

7 inches → 280 yards

1 inch → 280 ÷ 7 = 40 yards

5 inches → 40 x 5 = 200 yards

Area = 280 x 200 = 56 000 yards

Identify the vertex of the quadratic function in standard form y=2x^2 -16x+31
lapo4ka [179]

Answer:

(4,1)

Step-by-step explanation:

The vertex of the quadratic can be found using -b/2a. The vertex is the point (-b/2a, f(-b/2a)).

To find the x coordinate of the quadratic, define its a,b, and c. The quadratic has a = 2, b=-16, and c=31. Then -b/2a is -(-16)/2(2) = 16/4 = 4.

To find the y-coordinate, input the x=4 and solve for y.

y=2(4)^2-16(4)+31\\y=2(16)-64+31\\y=32-64+31\\y=1

The vertex is (4,1).
