Describe what happens to the x' and y-coordinates after a point is reflected across the x- axis

1 answer:

3 0

The y coordinate would become a negative or positive depending on the number. The x coordinate stays the same. For example, if the numbers were (3,2), then they the x coordinate, 3, stays the same and the y coordinate, 2, changes to -2 (negative 2).

Answer:

The answer is 384

A = 6 a^2 = 6 · 8^2 = 384

A = area

There are 6 sides to a cube, so you multiply the surface( 8 in ) squared by the sides.

In short, 8 · 8 (8^2) = 64

64 · 6 = 384

find the measure of the central angle of a circle if it's minor are length is 14π and the radius is 18 inches

MrMuchimi

Step-by-step explanation:

Length of arc of a circle is given as:

$l = \frac{ \theta}{360 \degree} \times 2\pi \: r \\ \\ \therefore \: 14\pi = \frac{ \theta}{360 \degree} \times 2\pi \: \times 18 \\ \\ \therefore \:\theta = \frac{14\pi \times \: 360 \degree }{2\pi \: \times 18} \\ \\ \therefore \:\theta = \frac{7 \times \: 360 \degree }{18} \\ \\ \therefore \:\theta = 7 \times \: 20 \degree \\ \\ \huge \red{ \boxed{\therefore \:\theta = 140 \degree}}$
