A) through (7, 1) and perpendicular to y=-x+ 3

Mnenie [13.5K]

Step-by-step explanation:

Two lines that are perpendicular to each other has -1 as the product of thir gradient.

Since the gradient of the line y = 3 - x is -1, the gradient of the other line must be 1.

So y = x + c.

When x = 7, y = 1. 1 = 7 + c, c = -6.

Hence the equation of the line is y = x - 6.

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
