Answer: option B is correct

Step-by-step explanation:

The custom glass table that has a top in the shape of a regular octagon.. It has eight sides, since it is a regular octagon, all the eight sides are equal.

The formula for determining the area of a regular polygon is expressed as

Area = pa/2

Where

P represents the perimeter of the polygon.

a represents the apotherm of the polygon. The apotherm is the perpendicular distance from the center of one side of the polygon to the center of the polygon.

From the information given, the apotherm = 1.2m

Perimeter = 8 × 1 = 8

Area of polygon = (8 × 1.2)/2

= 4.8m²

Answer:

Formula Area= .5xaxp

.5x1.2x8

You get the 8 by multiplying 8 sides by the size of each side remember a octagon has 8 sides of 8 sides by 1 meter= 8

Ms. Cassidy plotted the point (2, 3) on Miguel’s graph of y < 2x – 4. She instructed him to change one number or one symbol i

iris [78.8K]

Ms. Cassidy instructed Miguel to change one sign of the graph of y < 2x – 4 so that point (2, 3) can be included in the solution set.

To check which of the given options might Miguel write we check the inequality that holds true for the point (2,3).Substituting x=2 ,y=3 we have:

1) y < 2x – 1

3<2(2)-1

3<3 Not True.

2)y ≤ 2x – 4

3≤ 2(2) -4

3≤ 0 .Not true.

3) y > 2x – 4

3> 2(2)-4

3> 0 True.

4) y < 2x + 4

3<2(2)+4

3<8 True

5) .y < 3.5x – 4

3< 3.5(2)-4

3<3 Not true

6) y < 4x – 4

3<4(2)-4

3<4 True.

Options 3 ,4 ,6 holds true for the point (2,3)

Please help i have been trying to figure this out for like an hour

KengaRu [80]

Answer:

Step-by-step explanation:

Since x varies directly as y, the ratio of x to y remains the same. Let the value of x when y=4 be a. Then we have

$\dfrac {7 \frac12} {10} = \dfrac a4$

We can cross multiply to get that

$10a = 30, \text{so } \boxed{a=3}$
