What is the exact distance between the point (-2,-1) and the point (6,8) units

Studentka2010 [4]

Answer:

$\sqrt{145}$ units

Step-by-step explanation:

Distance between 2 points

= $\sqrt{(x1 - x2)^{2} + (y1 - y2)^{2} }$

Thus distance between (-2, -1) and (6, 8)

$= \sqrt{ {(6 + 2)}^{2} + (8 + 1)^{2} } \\ = \sqrt{8^{2} + 9^{2} } \\ = \sqrt{145} \: units$

Find the value of x (URGENT/GIVING BRAINLIEST)

alexira [117]

Answer:

D. 24

Step-by-step explanation:

Angles are the same, so 84 = 3x.

To get x alone, you divide 3 by both sides.

84/3 = 24

24 = x.

Marris decides to bake his parents a cookie in the shape of a regular dodecagon (12‑gon) for their 12-day anniversary.

allochka39001 [22]

Answer:

The answer to each question is:

A.) 403.2 $cm^{2}$
B.) 100. 8 $cm^{2}$

Step-by-step explanation:

A.) To obtain the area of the dodecagon, you can use the next formula:

Area of a dodecagon = 6 * apothem * edge

In the exercise, we have the edge (6 cm), but, to find the apothem of a dodecagon, that is the distance between the center of the polygon, and the middle point of each side, you can use the next formula:

Apothem = Edge * $\frac{2+\sqrt{3}}{2}$

If we replace the value of the edge, we obtain:

Apothem = 6 cm * $\frac{2+\sqrt{3}}{2}$
Apothem = 11.2 cm (approximately).

With this data, we can find the area:

Area of a dodecagon = 6 * apothem * edge
Area of a dodecagon = 6 * 11.2 cm * 6 cm
Area of a dodecagon = 403.2 $cm^{2}$

Then, the area of the dodecagon is 403.2 $cm^{2}$ approximately.

B.) As the area obtained is for 12 pieces, when the parents ate 9 pieces, just left 3 pieces, with these values you can make a rule of three.

If:

12 pieces = 403.2 $cm^{2}$
3 pieces = X

Then:

X = (3 * 403.2 $cm^{2}$ ) / 12
X = 1209.6 $cm^{2}$ / 12
X = 100. 8 $cm^{2}$

In this form, when the cookie has 3 pieces, its area is 100. 8 $cm^{2}$ approximately.
