Answer:

h = 400 ft

The bird is 400 ft above the submarine

Step-by-step explanation:

Given;

The submarine is 300 feet below sea level

Vertical distance between submarine and sea level h1 = 300 feet

The bird is flying at 100 feet above sea level

Vertical distance between the sea level and the bird h2 = 100 feet

The total vertical distance between the bird and the submarine is the sum of the vertical distance between submarine and sea level and the vertical distance between the sea level and the bird.

h = h1 + h2

h = 300 ft + 100 ft

h = 400 ft

The bird is 400 ft above the submarine

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = -x² + 10x - 6

f(-5) is x = -5

<u>Step 2: Evaluate</u>

  1. Substitute:                    f(-5) = -(-5)² + 10(-5) - 6
  2. Exponents:                   f(-5) = -(25) + 10(-5) - 6
  3. Multiply:                        f(-5) = -25 - 50 - 6
  4. Subtract:                       f(-5) = -75 - 6
  5. Subtract:                       f(-5) = -81

A flower garden is shaped like a circle. Its diameter is 40yd. A ring-shaped path goes around the garden. The width of the path
stellarik [79]

Answer:

Number of sand bags needed = 124

Step-by-step explanation:

Diameter of garden = 40 yd

Width of path = 6 yd

Diameter of garden with path = 40 + 2 x 6 = 52 yd

We need to find area of path.

Area of path = Area of garden with path - area of garden

\texttt{Area of path = }\frac{\pi \times 52^2}{4}-\frac{\pi \times 40^2}{4}\\\\\texttt{Area of path = }867.08yd^2

Area covered by one sand bag = 7 yd²

\texttt{Number of sand bags required = }\frac{\texttt{Area of path}}{\texttt{Area covered by one sand bag}}\\\\\texttt{Number of sand bags required = }\frac{867.08}{7}=123.86\approx 124

Number of sand bags needed = 124
